Seri is an attractive and tall woman with wavy shoulder-length blonde hair that has bangs swept to the right with neck-length hair strands hanging on either side, blue eyes  that additionally has long, feminine eyelashes  and she has a slender yet very curvaceous figure with large breasts.
When Seri is working, she usually clips her bangs to the right side of her head, aside from two locks that fall freely on both her left and right. She also ties her hair into two tight buns on the back of her head, with several loose strands flying out. Both buns are connected by a blue and white tiara-like hair clip.
As a Clansman hailing from Scepter 4, she wears their signature blue uniform, although hers is a more form-fitting variation of the outfit; a white long sleeve shirt tucked underneath a closed, blue overcoat with prominent black and gold-colored lining. Seri also wears a dark blue mini dress underneath that just barely covers her buttocks and a pair of knee-high, low-heeled black boots with metallic plates attached to the nose end.
Elsewhere, Seri generally lets her hair loose.
When she's out of her uniform, her attire is much more elaborate and girlish. She wears a flowing white mini-dress with a black sash around her waist, white stockings, and white high heels. Seri often brings along a white coat with fur ends on the sleeves with her. She also decorates herself with pearl accessories and visible makeup.
Seri is a very serious, dignified, calm and collected woman who has a nonviolent yet tough nature and prefers to avoid conflict if possible, negotiation being her most preferred solution to her problems.
Seri seems to put high regards in herself, and likely her leadership abilities, which may make her very reckless. This was evidently shown as she tried to re-imprison Mikoto Suoh, despite how Reisi Munakata ordered his clan to not fight him even if the Red King were to make his escape. Because of this Scepter 4 suffered heavy casualties and Seri later apologizes to her king, not in regards to how she disobeyed orders, but because she failed to recapture Mikoto and expects a suitable punishment. Reisi, not planning to give any punishments, instead points out to Seri that the entire failure was likely what symbolizes her level of arrogance. The Blue King also adds that she was very fortunate to be alive after directly facing a king, implying she could have easily been killed for overestimating her abilities.
Although Seri's prideful she does care about others even if they are clansmen of other clans. For instance, she is friends with Izumo Kusanagi or the time when Misaki Yata and Saruhiko Fushimi were fighting in Asahinka School's campus she stopped them and even told Yata about Suoh's condition (albeit in a sarcastic manner) which made him relax and postpone the fight. She was quite worried about Fushimi when after a fight with Munakata he walked away from SCEPTER 4 wondering that whether he even had a place to sleep; Seri later seems to become very hurt after confirming Fushimi's betrayal and wanted to know why Fushimi would go as far as to join Jungle.
When she is not at work, her personality drastically loosens up.
Seri's family runs a famous Japanese confectionery store. She ate all the anko she wanted until her middle school graduation, when her family forbade it to let her learn the difference between different kinds of anko. Her family then sells her the same azuki beans that they use in the shop, and she makes her own anko.
Before joining Scepter 4, Seri was always a top student in her academic grade, with notable leadership and business skills, and was appointed the vice-president of the student council. She excelled in sports, particularly kendo, holding status at the fourth dan. At her university, she won a beauty pageant despite not recalling ever entering it..
She later meets Reisi Munakata on an airplane. The airplane had been hijacked and nearly crashed until Munakata succeeded in landing it. There, Munakata revealed his status as a King, to which Seri was divided between dismissing him as frazzled with fear and instinctively believing his words, knowing she'd serve under him. The following day, Munakata invited Seri to Tsubaki-mon, and she only agreed to go because of how many questions she wanted answers to. She later left university in order to serve under Munakata.
At Tsubaki-mon, Scepter 4 was in disarray, the swordsmen disbanded and majority of the logistical staff working under Mihashira Tower's authority. Only a few clerks remained that Munakata introduced himself, explaining that he wished to familiarize himself with Scepter 4's documents. He revealed his Sword of Damocles, this being the first time Seri ever saw it. Instead of being afraid, Seri felt excited and inspired by the sword's presence, strengthening her conviction in serving Munakata. Over the next three days, both remained at Tsubaki-mon whilst Munakata went over tons of documents. When Munakata finished, he decided to take up an invitation from the Gold King he earlier declined. Before leaving, he once again addressed Seri with the topic of her joining him, offering a saber to her. Seri accepted the saber, becoming Munakata's Clansman.
Seri often instructs and supervises sparing training. At one point, she was challenged to a match by the young Takeru Kusuhara during practice. Seri immediately landed a blow on him with minimal effort. The boy continued to challenge her over the course of the next few weeks, losing every time and getting rather beaten-up by the lieutenant. In the end, Kusuhara finally was able to strike her in the chest, and she commended him for his progress.
One rainy day, Seri broke the heel of her shoe and fell. Izumo Kusanagi was passing by, and offered her refugee at his house. She put her clothing in his dryer and borrowed some of his casual clothing, much unlike her normal style. Izumo gave her a drink and tended to the wounds on her leg, observing that it may be unwise for Seri to trust a stranger and be alone with him in his house. Seri glared at him and Izumo said that he was only joking. The two knew each other as the number-twos of their respective clans, but hadn't engaged much outside of work until that point. Izumo then told Seri about growing up with Mikoto in high school. The two appeared to almost kiss, but Seri's phone went off, interrupting them. She changed and told Izumo she got called into work. Izumo told Seri she was always welcome back, and that she could also stop by his bar sometime for a drink. 
In the month of May, Seri received a phone call from Himori Akiyama and Dōmyōji, telling her that a horse Strain they've been looking for had recently fled while a member of HOMRA was riding on its back. She immediately told them to issue a chase. Seri then reported to Captain Munakata about the news, adding that HOMRA is likely to interfere, thus she additionally commanded her subordinates to avoid any Clan disputes .
Seri accompanies her Blue Clansmen to the hotel in which HOMRA is currently located in. Seri commands her subordinates to prepare for battle before doing so herself. However, no battle occurs, due to the Red King surrendering to them. Seri and her Clansmen then return to their headquarters.
She would later go to visit Reisi Munakata in his office where he discusses ideas as to how he can forever imprison Mikoto. Seri suggests that they try every possible option before administrating a killing blow, such as using drugs; however, Munakata turns down those ideas while telling Seri in how she was being negligent on Mikoto's human rights. They then bring their attention to the weapon used to kill Tatara Totsuka. Seri reports her findings and states that she would like to issue Level: Prussian Blue in order to run an investigation unit. She is told instead by Munakata to issue Level: Royal Blue; with her orders given, Seri leaves.
Seri, Himori Akiyama and Yūjirō Benzai later visit the country's Prime Minister, where Seri hands him a formal document to issue Level: Royal Blue. She explains that Scepter 4 will enter the Yuishiki System and that for two weeks, people will be disenfranchised of their rights; with her duties completed, Seri then leaves the facility with her two Clansmen. Seri later returns to headquarters where she and several of her Clansmen continue their research on Yashiro Isana; during their private investigation, Seri discovers that he is a student on Ashinaka High School. The information quietly surprises her.
Once back in headquarters, Seri launches the Yuishiki System and discovers an almost perfect match between Yashiro Isana and Tatara Totsuka’s murderer. She speaks to an unknown individual about doing her own investigation there and eventually receives authorization to do so. Seri brings along Himori Akiyama, Yūjirō Benzai and even Fushimi.
Seri and her team shortly arrive at Ashinaka High School, where she calls for a meeting with their principal. During the meeting, Seri asks to locate Yashiro within their student body system, despite the fact that she does not know who the student look-alike really is. Unfortunately, the principal is stubbornly reluctant to grant her permission to do so. With further efforts being futile, the meeting comes to a close shortly after.
While walking near the cafeteria, Seri notices Fushimi and a skateboarding Red Clansman fighting with their Auras in broad daylight. She swiftly stops them both from continuing the battle and scolds Fushimi afterwards for his recklessness in the situation; afterwards, Seri turns her attention to Yata. She grows uncomfortable when he refers to her by a specific nickname she was given in the past, though Seri quickly shrugs it off. She tells him to postpone the fight with Fushimi, only to be bluntly refused. Wanting to maintain a shred of peace among the two Clans, Seri reassures Yata that his King Mikoto Suoh is in good condition; the information relaxes Yata enough for him to leave quietly with Kamamoto. With the two HOMRA members gone, Seri then asks Fushimi what he learned from hacking into the school's database. She is told flatly that Totsuka's murderer does not appear to be a student at the school.
That evening, Seri dresses herself up and pays a visit to the HOMRA bar, where Izumo Kusanagi gladly greets her. Seri asks that he does not tell his Clansmen about the nickname he gave her. She then orders her drink. As she drinks from it, Seri states her confusion at how relaxed Kusanagi could be despite the fact that his King is imprisoned; quickly, the conversation turns to about Mikoto Suoh. Once Seri finishes her drink, she takes her leave, though she stops briefly to look at a jukebox owned by Totsuka. Seri is told briefly about Totsuka in regards to the musical item.
Later as it is now raining, she and several of her Blue Clansmen head to a soccer stadium in Shizume City. She dresses back in her uniform, then leads a group of her Clansmen to the field within the stadium. Seri draws out Kuroh Yatogami’s and Yashiro Isana’s attention and declares that Scepter 4 shall now take them both into custody. Upon hearing of their refusal, she and her men draw out their sabers.
Shortly after, they all find themselves in a location similar to the city's streets during the day, surprising them. While looking at the people walking around her, Seri extends her arm to one person, and sees them disappear upon physical contact. She concludes that it is a sensory interference and orders her Clansmen to seal the perimeters. Seri eventually sees Kuroh, Yashiro, and an unknown girl head towards an exit, making her launch an attack at them. Kuroh decides to take her on in battle, albeit without his sword to fight with. They initiate in a short-lived battle that is forced to come to an abrupt conclusion following the arrival of Reisi Munakata. Seri then remains on standby for the rest of her Clan's time in the stadium. In the end, Yashiro and his two accomplices escape from Scepter 4's hands.
The following afternoon, Seri has lunch with Munakata, namely a dumpling with multiple scoops of canned red bean paste topped over. During which, she reports that Fushimi's pursuit squads have all failed to capture Yashiro Isana or his two accomplices due to inclement weather. Seri adds that their Clan has already been tracking down possible escape routes that their targets could have taken and has furthermore sealed off the perimeters of Ashinaka High School.
Shortly after, Fushimi enters the room and gives a report of Chikushi’s recent attack from nearly fifteen minutes prior, providing any additional information requested by Seri and Munakata. Seri becomes troubled when she hears that Chikushi's PDA has been stolen and even more so when it is revealed that the attacker is Kuroh Yatogami. However, she continues to react calmly to the situation even when it is suspected that Yashiro will contact them within fifteen minutes. Seri even advises Fushimi to wait alongside her and Munakata for the time being, though he hesitantly refuses to. While she waits, Seri begins drinking tea.
Eventually, Munakata receives a phone call and answers to find that Yashiro is on the other end. While both are speaking, Seri begins to check her cell phone for additional information. Once Fushimi has left to continue pursuing Yashiro, Seri orders for him to be followed while completing his mission. Shortly after, she overhears Munakata explaining about the Silver King, Adolf K. Weismann, and while surprised she is reassured not to worry about his words.
That evening, Seri accompanies the rest of Scepter 4 to a local airport so as to use their helicopters and find a way to contact Weismann. On the ride to the area, she reports how Weismann has not responded to any of their contacts. Furthermore, upon the mention of such an idea, Seri explains that their Clan does not have the authority to launch an investigation within the Himmelreich. She suggests contacting the Gold King first about doing such actions but is told why they cannot do so. Munakata also explains that he will take full responsibility for what is to happen and thus, she should not worry about it, causing Seri to blush. Having understood Munakata's words, Seri then inquires that he explain his reasons for going to such measures to complete a task. Seri soon discovers that following Tatara Totsuka's death, each airborne route that the Himmelreich has followed for decades has suddenly been disrupted, making Weismann a suspect in the case.
Scepter 4 eventually arrive at the airport. Seri does not join most of her Clansmen in traveling to the Himmelreich, instead waiting on standby beside Munakata. Less than three minutes after the helicopters have taken off, there is an explosion occurring from within the Himmelreich. Furthermore, shortly afterwards one of the helicopters driven by her Clansmen crashes into the blimp's engine, resulting in an even more prominent explosion. Such events deeply surprise Seri.
Seri would leave the following morning to investigate the charred helicopter that has since crashed to the ground following the explosion. As she investigates it from a river, Seri discovers that it is unoccupied. Afterwards, she is informed by Benzai that the Clansmen who are supposed to have been boarding the helicopter are found in one of the airport hangers, apparently with no recollection of ever driving their vehicle with the others. Astonished, Seri wonders who was actually driving the helicopter from the previous night.
Much later, back at headquarters Mikoto Suoh successfully breaks out from his cell and escapes outside. Seri and her men block the exit, where Seri additionally tries persuading the Red King into stopping himself from continuing forward. When he ignores her, Seri attacks him with a binding technique, though it is easily dispelled upon contact. This both surprises and worries her. Afterwards, she becomes paralyzed with fear and disbelief as Mikoto attacks Scepter 4 with a destructive fiery attack. Despite Fushimi attempting to block with a barrier, Seri and the others are stricken down. Injured, Seri overhears one of her men calling for backup, though she weakly states that it is futile.
Seri eventually recovers from her injuries, and along with the rest of her Clan, moves out to the front of the bridge connecting to Ashinaka High School. While in one of the trucks, she apologizes to Munakata for her failures to prevent Mikoto Suoh from escaping his cell. Seri states that she will accept full responsibility but hears from her Captain that saying such words only makes her sound arrogant. Nonetheless, she does not speak out against him.
The two walk outside and reconfirm the dangerous situation regarding the Red King together. Seri concludes that Mikoto is at the school so that he can apprehend Tatara Totsuka's murderer, who apparently is the Colorless King, furthermore a type of "wild card" between him and the other Kings.
The following morning, Seri stands alongside her Clansmen as they wait on Munakata's orders. Akiyama and Fushimi persist on heading to the high school campus, though she becomes annoyed and adds that using other methods of entrance would be easily burned down by HOMRA. An explosion is then seen from the island, greatly concerning Seri; however, seeing it also convinces Munakata to let his men advance.
Scepter 4 makes their way to the campus where they are met by members of HOMRA; using a speakerphone device, Seri warns the Red Clan to drop their weapons and surrender or otherwise be dealt with accordingly. Her words are ignored entirely, causing her to turn to her Captain for further commands. She notices Munakata gazing towards the main building of Ashinaka High School and asks him again, to which she is told that she will now be put in charge; momentarily surprised, she immediately understands and calls out for her other Clansmen to draw their swords. Fighting then ensues between HOMRA and Scepter 4, though Seri watches the battle from afar.
Multiple explosions from within the campus then draws out the attention of everyone in the vicinity; surprised, Seri wonders what is happening. She becomes worried for Munakata when he heads out towards the explosions. When Munakata stops in his path to protect a HOMRA member from being struck by the debris, only to be stabbed by the same man, Seri runs out towards her Captain to try and save him; unfortunately, Munakata's Aura shield dissipates before she can and the debris collapses on the men anyways. Shocked, Seri stares blankly at the scene and becomes even more astonished when further explosions are heard.
Seri regains her composure later during the battle against HOMRA, even reminding her Clansmen to stay composed and that their group combat cannot be beaten. However, she is constantly distracted by Munakata whom she keeps looking out for towards the high school's main building, even while being attacked abruptly by Misaki Yata. Seri is nearly struck by one of his attacks though Fushimi manages to defend her before it can occur.
Later, a beam of silver light emerges from within Ashinaka High School, awing and confusing Seri . She leaps onto the roof, aiming to find Reisi and help him. Instead, she runs into Yashiro Isana and Neko, now floating with his umbrella and Silver aura. He taps into her personal aura and transfers some of his own, making her a temporary member of his Clan so she can use the power of flight. Confused and disturbed, Shiro transports Seri to a classroom, where Izumo Kusanagi and Anna Kushina are waiting. It is revealed that Shiro is in fact the Silver King, not Colorless. After a phone-call from the Gold King, Shiro asks Seri and Izumo to call off their troops and evacuate. They agree, still rather perplexed.
After leaving, Seri waits with the rest of Scepter Four on the bridge overlooking the school island. When Fushimi arrives much later, Seri expresses that she thought he had rejoined Homra, his old Clan. The two then discuss how Kings mostly keep to themselves as they patiently await Munakata's return.
K Missing Kings
Seri is seen contacting Izumo Kusanagi who just came back from Germany after gathering information about Dresden Slate. She told him that the Gold King, Daikaku Kokujōji has been away without any specific information about his current location. Later, the Blue Clan and her draw their swords to honor the new Red King, Anna Kushina.
In between the events of Missing Kings and Return of Kings, Seri and Fushimi accompany Reisi to his family's house. Because they are not working, the group is dressed casually. Fushimi expresses desires to leave, to which Seri responds by violently shaking him and begging him not to leave her alone there. She meets Reisi's parents, and his mother thanks her for everything she's done for Reisi. Seri stutters that she should be the one thanking them. 
Later on, Seri visits Izumo at Bar Homra. Izumo notices that she's spacing out and asks what's wrong. Seri crosses her arms and says it's nothing. Anna walks in in a lion suit and sits next to Seri. Anna seems to be a bit embarrassed to be dressed that way around a Blue, to which Seri giggles and says she finds it a little unexpected for the newborn to worry about her dignity as a King.
K Return of the Kings
In the opening flashback, the Blue Clan confronts the Red Clan atop a building. When a fight breaks out, Seri challenges Kusanagi, who accidentally tears a part of her clothing. She asks him what is so funny, to which he shrugs and they continue fighting. 
Back in the present, it is nearly a year since the school island incident. Seri begins to express concern for her captain's condition. Due to this, she holds a private meeting with Gōki Zenjō, former second-in-command under the previous Blue King. Seri asks if there was any change in Jin Habari before Zenjō was forced to slay him to prevent a Damocles Down. Zenjō realizes Seri is worried that the same fate will befall Reisi, and tells her that he is no longer the Blue King's right hand man; she is. 
Later on, Seri attends a meeting with the Red and Silver Clans. She is surprised when Reisi agrees to join forces with the two other Clans in order to combat JUNGLE, the Green Clan. They form the Coffee Table Alliance, and afterwards Seri and Izumo discuss what to do with the documents the latter recovered from Germany earlier that year. During a strategy meeting, Seri asks Shiro about Nagare Hisui's reckless decision in the past to challenge the Gold King. She then stays in the room and overhears the Red and Silver Kings discussing the Blue King's current condition.
On Christmas Eve, Seri and her troops wait on the first floor of Mihashira Tower, ready to confront Sukuna Gojo and Yukari Mishakuji, two of the very few clansmen of JUNGLE. They manage to get in on their quest to steal the Slate, but get separated when chasing the Blue Clan. Seri regroups with Homra on a floor above, where Yata criticizes Reisi and questions why anyone would want to follow him. Izumo apologizes to Seri as Yata gushes that he wasn't referring to her, but rather Fushimi. Seri doesn't respond. When the operation ultimately fails, Fushimi quits Scepter Four. Seri calls Izumo Kusanagi, asking if Fushimi took refugee in Homra. Izumo tells her no, and asks what's happening. Despite being know for being cold and heartless, Seri is genuinely worried for Fushimi, wondering if he even has a place to sleep now that he has walked out.
About a month after the incident at Christmas, Seri and Izumo infiltrate a JUNGLE start-up party, posing as a married couple. Seri is worried about the whereabouts of Fushimi, to which Izumo comforts the lieutenant and encourages her to try and have some fun. Upon entering, Seri notices all the famous figures in the room, including the Japanese Prime Minister. After the couple splits in search of information, Seri overhears the Prime Minister expressing support for JUNGLE and criticizing Munakata. She steps on his foot with her heel and pretends to faint into a masked JUNGLE player's arms. This allows for her to lure him into a side room, knock him out, and steal his PDA. She tosses it to Kusanagi, who finds the party's invitation list. 
After exiting the room, JUNGLE members start to chase them. Seri and Izumo run to an elevator, where one of the masked members grabs her. Izumo and Seri fight him off and escape, only to have the PDA knocked out of their hands with a dagger, a trail of green lightning following it. They hear a voice identifying the player as Saruhiko Fushimi, now a J-rank. As Izumo attempts to stop him, Fushimi escapes with the help of Douhan. Obviously distressed, Seri starts towards Fushimi, but Izumo regretfully suggests they call it a night as more JUNGLE players approach. 
Back in the Blue Clan's headquarters, Seri discusses the event with Reisi, who almost appears unfazed by Fushimi's second betrayal. Zenjō then walks in as Reisi explains he transferred the Ogre to the Special Police Force. Seri reaches for her sword, shaking, as Zenjō unleashes his own blade to precisely strike a fly buzzing around the room. Later, when Munakata is dismissed as Captain, Seri visits the Prime Minister, angry, demanding an explanation. Scepter Four is ordered to stay put and not interfere with JUNGLE.
Later on, Seri is overseeing the men as they gather data in their base, restless. When they find footage of Munakata and Zenjō heading towards the Green Clan's stronghold, Seri decides she can't stand by any longer. Unable to disobey direct instructions for the Blue Clan not to interfere, Seri temporarily resigns from Scepter Four. She lays down her sword and expresses that she still wants to remain Reisi's right-hand man. She then places Himori Akiyama in charge, who tells the men that they will also go to aid the Captain. Seri is taken aback, mad that they are disobeying orders. Akiyama tells Seri that she is no longer the lieutenant, and instead an ordinary citizen that they need to protect. However, he hands her back her saber for "self defense". Seri nods and tells them all to move out.  When Reisi faces off against Tenkei Iwafune, he is knocked down and struggles to stand. At that moment, the Special Police Force charges in, fighting off the surrounding JUNGLE members while the rest of Scepter Four takes control of the chaos throughout the city. Seri steps up in front of Reisi and asks if he's alright, still referring to him as Captain even though he was fired. When the Gray King attacks, Seri stands at the head of the Clan, creating a forcefield to protect Reisi as he stands. Reisi is able to strike Iwafune, who is defeated in a pool of blood. As everyone celebrates, Seri notices that Munakata's Sword of Damocles has not yet disappeared. When she asks him to remove it, Reisi replies that he cannot. Seri sees the sword crack more as blue debris fall from it. Seri leaps forwards and stretches her arms out in front of Reisi, warning everyone, even Zenjō, to get back as she draws her sword. She tells them that she is second in command, and if Reisi's Sword should fall, she would be the one to slay him. 
Once the Slates is destroyed, Reisi chuckles as his Sword fades forever, realizing his life has been spared. He turns around and thanks Awashima for her efforts, and admits that he was curious as to whether or not she would have been able to slay him. Seri is relieved, but tells the former King that his gratitude would not be enough. She asks him to forgive her and punches him, knocking his glasses off and leaving a rather large red mark on his face. Zenjō smiles as Munakata instructs Seri to make sure everyone evacuates.
Sometime after the destruction of the Slate, Seri and Izumo go shopping for a Scepter Four fundraiser. The two go out to eat together, but soon realize that they must look like a couple to strangers passing by. Izumo then invites Seri to dinner, which she accepts. She goes to the bathroom to fix her makeup when she receives a phone call, calling her back to work. Reluctantly, she has to decline Kusanagi, but the two continue to meet at his Bar regularly.  The Blue Clan takes a group photo.
K Seven Stories
Circle Vision: Caught in a dream-world after the events of Return of Kings, Seri joins Scepter Four as they enter a fray between the Green and Red Clans. It turns into an all-out war, with the Silver Clan soon joining. Seri clashes swords with Douhan Hirasaka several times. After the giant fight, Seri wakes up in her bed, startled. The same events happen over the next few days, with Seri commanding her troops with flawless results. She begins to suspect that things are too good to be true, and visits Izumo at Homra. Due to the Clan sleeping inside, the two have their date out in the gentle snow. Izumo hands Seri a warm drink as she asks him if he's satisfied right now. Seri confesses that things seem too perfect to be real, and the two look inside the bar to see Tatara and Mikoto, alive.
One night during the fighting, Seri notices a bright light. She starts towards it before running into Reisi, asking his permission to investigate. He smiles and asks her if that is even necessary. Seri reaches the source and runs into members from all the Clans, who are caught up in the same dream. The group is introduced to a small child, who is the human embodiment and remnant of the Slates. He exports them to a black screen, showing the group images of better times and people they've lost. Seri finds out that the dream-like state was created by Sukuna Gojo's wish. The Slate wonders why they desire to leave the "dream", which Seri responds that they have to advance instead of dwelling on what they've lost. She joins the rest of Scepter Four to salute the Sword of Damocles one last time. Seri finally wakes up, ending her section of the dream. 
Powers & Abilities
Blue Aura: As a member of the Blue Clan, Scepter 4, Seri possesses Blue Aura. It typically takes the form of a thin, bluish wisp capable of scorching through the ground, even through wet grass; typically, it leaves behind a trail of smoke in its path.
- Aura-Enhanced Slash: When in combat, Seri combines both her Aura and swordsmanship to enhance her attack. She exerts her Aura enough to have it "shroud" over the blade of her saber. Seri then swings her saber and thus, ejects the Aura in a line determined by how she performed the action. It cuts across the ground and leaves behind a smoke trail, and in some cases, rupture to the ground itself.
- Arrow Attack: She first exerts her Aura onto her saber's blade and swings it vertically, causing the Aura to eject in a vertical formation. Seri repeats the move but instead creates a horizontal slash. The Aura ejected from both strikes eventually intersect and form a fast-moving, spinning structure that develops into a blazing arrow. As with its less elaborate version of the technique, its results always leave behind a trail of smoke, though the damage it causes is determined by the terrain. (unnamed)
- (to Saruhiko Fushimi) "I thought maybe you went back to your old gang."
- "Four Kings haven't come together since perhaps the Kagutsu Crater Incident."
- "You might be right. Maybe that's why they're only attracted to other Kings."
- "I am the Blue King's lieutenant. If necessary, then I will [slay him]."
- The name Seri means "world" (世) (se) and "reason, logic" (理) (ri).
- Seri is derived from Suseri-hime (須世理姫, Suseri-hime); Suseri-hime was known to have helped her husband, Ōkuninushi, the deity of Izumo-taisha, pass the harsh test of her father Susano-o.
- Seri's surname Awashima means "light, thin, faint, pale, fleeting" (淡) (awa) and "island" (島) (shima).
- Awashima is derived from "Awashima-no-kami", a Japanese folk religion deity who blesses women.
- Seri's sizes are B95/W57/H92.
- Seri's hobby is collecting small articles.
- Seri appears to have an unusual preference for red bean paste, putting a lot of it in her alcoholic drinks or daytime snacks.
- Takako (Seri's highschool friend) said that she is nicknamed "Awashima the Hundred"/"Hundred" because her bust measurement is 100cm. Hiyori (another highschool friend of Seri) and Seri refute this, saying Seri's bust measurement is actually only 95cm. Hiyori and Seri then explained that it's actually because Seri eats 100kg of anko a year. Although Seri told her friends that they can call her "The Three Hundred" now, she actually still eats 100kg of anko a year; the 200kg left is actually the amount she tries to feed to the Scepter 4 members .
- Seri and Izumo Kusanagi may be the only canon relationship in the series. In the movie Circle Vision, Izumo states that they are having a date outside of Bar Homra.
