K: Days of Blue
It is mentioned that before joining Scepter4, Hidaka had just graduated college. Not knowing what to do with himself, he saw a recruitment ad for Scepter4, decided to give it a try and ended up being accepted.

K SIDE:BLUE
Before the formation of the Special Duty Corps, Hidaka was shown to be a part of Doumyouji Andy's Fourth Squadron, alongside Daiki Fuse, Tatsuya Enomoto and Ren Gotō. He was also a good friend of Takeru Kusuhara who always going out of his way to hang out with him or visit him while in the dojo with Gōki Zenjō, and was shown to be the most affected by his death within the squad.

Plot
Akira and others from his group are called to a hotel suite that another group, HOMRA, is currently occupying. Under the orders of Seri Awashima (Akira's superior), he draws out his sword in preparation for the battle between Scepter 4 and HOMRA. However, due to Munakata's persuasiveness, there is no such event and the HOMRA's Red King is imprisoned. Sometime after, Akira joins his colleagues when extracting information about Yashiro Isana.

Sometime later, he joins several members of his Clan to a local soccer stadium to confront Yashiro and Kuroh Yatogami. Akira takes his battle stance under his Lieutenant's orders, though he remains on standstill throughout the whole event.

The following afternoon, Akira is assigned to continue pursuit of Yashiro and his two accomplices. The group finds themselves on a freeway in Shizume City. There, they stop and Akira takes the time to ask whether their forces are enough to handle Yashiro's own team, seeing as one of his accomplices is capable of fighting on equal ground with Lieutenant Awashima. In response, Saruhiko reminds Akira of their main objective, before then leading him and their other Clansmen to a nearby pickup truck. Akira and Fuse begin to interrogate the driver, who explains that he is only delivering cargo for his company. As it turns out, there is no one else occupying his vehicle.

Akira would later join his Clansmen to a local airport so that they can use the helicopters there and bring the Silver King, Adolf K. Weismann, from the Himmelreich so that he can be taken into custody. Eventually, they arrive at the airport and board the helicopters, taking off to continue their objective. However, due to the unexpected explosion of the Himmelreich, doubled with a crash impact into the aircraft's engines from one of the Blue Clansmen's operative helicopters, followed by a subsequent crash landing of both vehicles, Scepter 4 ultimately fails their mission.

The following day, things did not improve. Mikoto Suoh manages to free himself from his shackles and successfully break out from his prison cell, despite the combined efforts of multiple Blue Clansmen, including Akira, to keep him confined. As such, Akira and several other Clansmen hurry outside to barricade the exit and prevent the Red King from escaping the vicinity. Unfortunately, they fail to complete their task and Mikoto ends up leaving the area with several members of HOMRA, who have arrived to accompany him back home. Akira prepares to fight them off though he is forced to draw back at Fushimi's orders.

Akira later joins his Clansmen to the bridge connecting to Ashinaka High School; as per orders, Akira waits until he is told to enter the school's campus. The morning after, he asks Seri Awashima about the matter but is coldly ignored. Moments later, an explosion occurs on the campus and surprises Akira, causing him to wonder whether it is the work of the Red King. Finally, it is then that Munakata orders his subordinates to make their move.

Scepter 4 makes their way to the campus where they are met by members of HOMRA, who rebuke Seri's warning to them and cheer on for the inevitable fighting. Akira readily draws his saber to Seri's command and subsequently fights against the members of HOMRA alongside his Clansmen; among his primary opponents is Saburōta Bandō. The fighting is momentarily halted by a sudden explosion deeper within the campus, followed by an attack on Munakata from the HOMRA member whom he was protecting from the collateral damage, though they continue fighting shortly after.

Later, a beam of silver light emerges from within Ashinaka High School, awing and confusing Akira.
