Yashiro Isana

is an amnesiac teenager accused of killing Tatara Totsuka. He is the former vessel of the new Colorless King and currently the vessel of the Silver King, Adolf K. Weismann.

Appearance
Yashiro is a male teenager of average height with messy, gray hair and amber-colored eyes.

He wears his school's uniform at almost all times. It is composed of a long-sleeved white shirt with an upturned collar, connected to a loose red ribbon around his neck. He wears a dark blue jacket left open. His pants are dark blue and his shoes are brown.

He carries a red, Japanese parasol with him at all times.

Personality
Yashiro is an easy-going and extremely charismatic person. He often uses his charisma to help him out of difficult situations, such as tricking Kuroh into believing that he has a younger sister. Nonetheless, Yashiro is able to get along with almost everyone, whether it is people or animals or robots. He is kind hearted and very open about his feelings to everyone.

History
Late during the night, through unknown circumstances, Yashiro was pushed to the edge of an open blimp. He barely manages to hold onto the aircraft and tries clinging on for his life. A tall, long-haired man named Adolf K. Weismann looked down upon him and kicked him out, causing Yashiro to plummet several hundred feet into an old shed.

He eventually crashed into an island just outside Shizume City, specifically on the campus of Ashinaka High School. He broke through the roof of the school's gymnasium and landed on a mattress-like object, completely unharmed. He rose from it and noticed a pink cat near him in the dark, hissing in annoyance. Yashiro apologized to the cat and it quickly became attached to him, hopping on his lap so that Yashiro can hold and stroke its fur.

The door to outside then opened and a teenage girl named Kukuri Yukizome entered the building. Yashiro is soon discovered and inquired about his name. He notices a poster for Ashinaka's upcoming festival and hesitantly said that he was Yashiro Isana. Kukuri slowly starts to recognize Yashiro as one of her classmates and accuses him of slacking off during the production for the school festival. Subsequently, when asked about the hole he made in the roof, he stated that he did not know what happened. However, Kukuri did not believe him.

Since that night, Yashiro was led to believe that he was a high school student, and that he'd left his parents to go study at Ashinaka High School.

Plot
After getting rice for his lunch, Yashiro asks several of his classmates to share their lunch with him, to which they oblige. Afterwards, he goes across campus trying to get more people to share, even attempting to sneak food from the cafeteria. Once his bento is completely filled up, Yashiro heads to the rooftop of one of the school's buildings to eat his lunch. The pink cat from before accompanies him and also eats his meals. Yashiro lazily stretches his arms and says that Japan is a great place. He then takes a quick nap.

Yashiro then returns to class with the little cat. He notices that everyone is not studying and wonders why, only to learn that they're preparing for the school festival. Kukuri asks for someone to help run errands for the school council and Yashiro is chosen to do so. She attempts to send him a list through their PDAs, but Yashiro cannot find his, so she writes it down. Kukuri also tells him that he needs to find it otherwise he can't leave campus, but he tells her not to worry, taking the note with him. Yashiro finds a key to one of the doors inside campus and uses it to maneuver through security, rather than having to leave using a PDA. He then walks to the city on the bridge.

While in the city, he manages to purchase the items from a local store. While walking out, however, Yashiro is suddenly attacked by a male teenager with a skateboard and a baseball bat, causing him to drop the items and try to run for his life. He runs across town, hopping onto people's vehicles, and even crosses through alleys to get away. He is soon cornered into an alley where a blonde man attacks him with unusual fireballs, which he conjured from the sparks on the cigarettes he's been smoking. Luckily, a long-haired teenager arrives and saves Yashiro from the mysterious people.

The teenager takes Yashiro to the rooftop of another building just near the train station. Yashiro thanks the male and tries to go off on his way, but is prevented from doing so. The teenager introduces himself as Kuroh Yatogami and explains that he is the vassal of the Seventh King, Ichigen Miwa, and that he must also slay the "evil" King. Yashiro is confused by his words. He is even more confused when a video, depicting a man nearly identical to Yashiro, is shown across town through a network hijacking. Kuroh claims that the man in the video is Yashiro himself.

Kuroh adds that under his master's orders, he will take Yashiro's life. Yashiro attempts to run away but is caught by Kuroh's Aura, suspending him in the air. A frightened Yashiro asks if Kuroh will actually kill an innocent man such as himself. He is then dropped but caught in Kuroh's arm. Yashiro continues arguing that he is actually innocent, though he is unable to convince the sword-wielding teenager.

Yashiro seemingly gives up hope resisting and says that Kuroh can do whatever he wants with him as long as he grants him a final request. He is freed from Kuroh's grasp and explains that he has an ill younger sister, who has been hospitalized for most of her life, and that should he die, she would be left without a family. Yashiro asks to write a letter to her so that she will know he's not actually a murderer. Kuroh allows him and then asks to see the letter. Once he does, Yashiro sets off a barrage of flash bombs, using the distraction to seemingly run away. Kuroh runs off after him, though it turns out that Yashiro had quickly disguised himself in an animal suit during the distraction.

Remaining disguised, Yashiro walks around town, completely unaware of the fact that a bounty with his face on it has been sent throughout the city. While walking about, he spots Kuroh again, and quickly retreats. He heads to a rooftop and removes his disguise just before Kuroh and Misaki Yata, the same person who attacked him before, begin their fight. Yashiro tells Kuroh to meet him on the rooftop after he beats up Yata. However, he leaves before the fight ends.

Yashiro returns to his school and sneaks back in the dormitories. He lies on his bed, completely exhausted, with the pink cat resting beside him. Yashiro speaks aloud wondering who the people who attacked him are, as well as how the video came into place. He mutters that it will be hassling and hears someone responding to him. Yashiro turns around to see the pink cat gone, and instead, a naked Human girl instead. Embarrassed, he jumps off his bed and asks who she is, only to be told that she is Neko. Yashiro picks up his jacket and tries handing it to Neko, but she refuses the piece of clothing. He then hears Kukuri shouting out for him outside and goes to look. Yashiro sees Kuroh next to her, surprising him. Using his Aura, Kuroh pulls himself up to Yashiro's dormitory. He draws his sword, attempting to kill him, but is distracted with Neko's nudity whilst before him. Neko takes this opportunity to run away with Yashiro.

While running in the hallways outside his room, Yashiro throws his jacket on Neko, startling her. He then witnesses an abrupt change in the hallways; suddenly, Neko is further away from him. When she exits the building, it reverts back to normal, surprising him. Yashiro continues following Neko throughout the campus while additionally avoiding Kuroh, who still strives to kill him. The three-way chase continues for the rest of the day and well into the night, lasting until morning, which by then has left them completely exhausted. They stop in Yashiro's room where everyone begins to show signs of hunger. Yashiro suggests that they end their conflicts to have breakfast and proceeds to make some, though he is unable to figure out how to cook his meals, as well as trying to cook food that appeals to Neko's picky tastes. However, Kuroh ends up cooking for the three of them, and they have breakfast together.

Most of the breakfast was filled with Yashiro asking various sorts of questions, such as having the soy sauce passed to him or what Kuroh's recorder was. However, one of the things he also inquires about are the HOMRA members who chased him before. Though confused throughout the entire explanation, Yashiro does understand that they are Red Clansmen led by the Red King, Mikoto Suoh. He also discovers that the reason they're after him is because of his uncanny resemblance to the man who murdered one of their own members. Kuroh reminds Yashiro that he will kill him once they've finished eating, still believing him to be Tatara Totsuka's murderer. Yashiro denies this claim before he asking for seconds.

Once he's received another full bowl, Yashiro finally asks Kuroh as to why he would want to kill him. He is explained that it is because, as per the murder video, Yashiro is to be the next Colorless King but has been deemed evil; thus, he must be killed by the vassal of his planned predecessor. Yashiro fruitlessly argues further with Kuroh, before he would then ask about the Kings. Yashiro receives another explanation about them, discovering their immense power and authority over Japan. In relation, he hears more about the Red Clan HOMRA and its known Clansmen.

Yashiro, Kuroh and Neko give their thanks for the meal at the end of breakfast. Kuroh proceeds to kill Yashiro though he stops him again, persisting that he is innocent before making a request to have his words be tested. In response, Kuroh has him play a message on his recorder, stating that it has saved his life. Yashiro is relieved to hear that his request will be given. He asks again about Kuroh's recorder; once explained about its history and usage, he comments on how Kuroh is creepy.

The next morning, Yashiro awakens to see that Kuroh has prepared lunch for the day. While ogling the food, he notices a cleaning robot taking away his backback. Yashiro tells it to stop but ends up being mistaken for trash, causing the robot to attack him. During class, instead of studying Yashiro writes down what he would put in his alibi. His teacher comes towards him to ask about Kuroh and Neko, to which he explains that they are supposed to be transfer students. Yashiro eats his lunch with Kuroh and Neko. Throughout most of the break, he attempts to analyze the video of Totsuka's murder, sent by Mishina to Kuroh's cell phone. However, he is unable to identify much from the blurriness in one of the video's screenshots.

Once the lunch break is over, Yashiro goes to change into his Feudal Japan outfit with Kuroh and Neko. While changing, he tells Kuroh that he can prove that he was on campus during that day, specifically within the hour of Totsuka's shooting. The three scavenge for information of the such across campus, from the student council's office to the courtyards near the clock tower. Eventually, Yashiro gets his proof from the teachers' office, where he asks for a log of the number of entries and leaves within school campus. Since his name is not on the list during that day, Yashiro believes that Kuroh can no longer hold it against him.

However, while getting a drink for Neko, Kukuri ends up revealing that he generally just sneaks out of campus, therefore bypassing the school's gates that log everything. As a result, Kuroh deems him insincere and prepares to kill him. Yashiro is protected by Neko, though he pushes her behind him to confront Kuroh himself. Yashiro argues that he can find an alibi that proves he was on campus during December 7-8. Sure enough, Kukuri reveals that she did see him on campus approximately 12:30 AM, proving his case. He celebrates happily and tells Kukuri that he owes her his life.

Yashiro returns to his dormitory, where he comments on how exhausted he is. He goes into his closet to look for a shirt. When he finds one, he horrifically discovers that one of them is bloodstained, just like the ones in the shirt worn by Totsuka's murderer. Though horrified, Yashiro is approached by Neko, who notices that he feels uneasy. He states that she shouldn't worry, though wonders in shock whether he did kill Totsuka.

Yashiro goes with Neko back to his classroom. There, he sits by a desk and wonders about his connection with Totsuka's murder. He is then told to help with the festival production, specifically to run more errands in the city. He has Kuroh and Neko accompany him along the way. The three take the secret exit beyond the school gate, where Yashiro explains that he lost his PDA; therefore, he can't exit normally. While walking along the bridge, Yashiro stops to look out the oceanic horizon.

The three eventually stop at at a restaurant in the city. While he's dazing off, he is reminded by Kuroh that while he may not be proven guilty, there are still many suspicions surrounding him. Yashiro quietly agrees. He then notices a bulletin board next to him with several photos of his classmates on it. Yashiro asks the restaurant owner about them, pointing out that his own photo is nowhere on it.

Once they've all eaten, they head to a store in the city to purchase the fireworks. However, Yashiro's poor penmanship makes it difficult for Kuroh to see what specifically they need to get, and so he decides to call Kukuri; because of this, Neko runs away from them. Yashiro uses Kuroh's cell phone to call Kukuri and ask her about the fireworks; however, Kukuri is unable to recognize him and eventually hangs up. Disheartened, Yashiro explains what happened. He then asks to call his family, wanting to be reassured that there are people who know who he is. Yashiro calls his home but an automatic dial informs him that he cannot contact the number.

Yashiro and Kuroh take a train to a soccer stadium, where Yashiro believes is where his house should be. He admits that it's possible that he may not be who he believes he is, and that Yashiro Isana might not even exist. As tears begin falling down his face, Yashiro wonders whether he actually is a murderer, and asks Kuroh if he still wants to kill him. He readies himself for death. Instead, he is left at a standstill when Kuroh plays a message from his old master. Yashiro wonders what Kuroh means with the message and is told that he will only kill him with certainty. In other words, until he is certain about his actions, he will not kill Yashiro, nor let him give up hope.

A cheered-up Yashiro tries to speak when the headlights around the stadium suddenly flash at his location. Once the brightness has toned down to a more bearable level, members of the SCEPTER 4 force reveal themselves, telling Yashiro and Kuroh that they will be taken into custody. Yashiro suggests to surrender willingly but is ignored completely. He looks on as Kuroh and the uniformed people prepare for battle, only to soon discover that the terrain has changed completely.

It is then that Neko arrives and takes Yashiro with her towards an exit. They are forced to stop by a blonde-haired woman and eventually her Captain, who dispels the landscape effects that are revealed to be of Neko's doing. Kuroh tells Yashiro and Neko to leave, even clearing an exit for them. Although reluctant, Yashiro leaves with Neko. However, while inside the stadium, he looks back towards Kuroh's location with concern.

Eventually, Yashiro decides to go back to the fields while cloaked in a white light and sees that Kuroh is pinned to the ground. He tells the man over him that he simply cannot let his friends get hurt. He then turns his attention to Kuroh himself. Yashiro apologizes for keeping secrets and exposes a white sphere in the palms of his hands, which hovers over him and transforms into a giant key-like object. His voice suddenly starts to reach out to Kuroh's thoughts. Yashiro exerts a white force from his body and counters against the SCEPTER 4 Captain's own Aura. Afterwards, he disappears.

Together with Neko, Yashiro leaves the stadium and eventually finds a beaten Kuroh inside an alley. Though worried, he is told not to be. As Kuroh slowly recovers, Yashiro begins to praise Neko for her efforts at the stadium. Eventually, he is told from Kuroh that Neko has the ability to manipulate memories, making Yashiro wonder if she can do anything about his.

Kuroh reminds him that if his memories prove that he is actually an evil person, he will be killed, though Yashiro does not mind it. He tells Neko to reveal his true memories to him and she does so; although, Yashiro can only recall the night that he first met Kukuri. Yashiro asks for Neko to try and uncover his past from before then. She manages to show him his innermost memories from the same night: him being pushed off a blimp by a silver-haired man. Shocked, Yashiro wonders who he is.
