## Story

BJ's true identity is Miura Keitaro from one loop ago, who assisted Chihiro Morimura from two loops ago in defending the world one loop ago from the Kaijus. When Sector 4 fell and the world was about to be reset, Miura, along with Tamao Kurabe, Takatoshi Hijiyama, and Tomi Kisaragi from one loop ago, were instructed to escape to Sector 0 using a Type-98 Biped. However, the Type-98 Biped exploded during the transfer, presumably attacked by a Kaiju. As such, all four of them lost their physical bodies and arrived in the new loop as AIs.

In the new loop, the AI Miura (now called No.17) was installed as the pilot of Sentinel No.17. During this time, Miura discovered a massive amount of records from the year 2188 in Universal Control, which he was able to partially decipher. The AI Tamao (now in an android body developed by Tetsuya Ida) found out about this and decided not to report, but asked him to stop. Tamao refused, and asked Tamao to never disconnect her connection with him even if something happened to him.

Having became friends with Ei Sekigahara, Miura told him about the records of 2188, and how Morimura isolated it to keep others from accessing it. However, he kept a backup in the memories of Sentinel No.17. Miura asked Sekigahara to recover Sentinel No.17's memory module should anything happen to him.

Miura and No.17 participated in the battle of Sector 2 alongside 18 other Sentinels. However, the battle was lost due to the spread of DD-426, which disabled all Sentinels. Morimura decided to activate emergency transfer on all of the Sentinels to save them, causing them to be randomlmy scattered over all Sectors. However, Miura relocated into his Sentinel's Scout Unit and detached from the Sentinel before the transfer.

Miura's Scout Unit was recovered by Ida Tetsuya. However, he refused to cooperate with Ida's plan of intentionally causing another reset. Knowing that Miura had a backup of the 2188 records in his Sentinel. Since Miura still had the control authorization of Sentinel No.17, Ida was unable to track it, so he enlisted the help of Sekigahara. In the ruined Sector 3, Ida instructed Sekigahara to pretend to rescue Miura from him and trick him into revealing Sentinel No.17's location.

While en route to the Universal Control under Sakura High School, Sekigahara and Miura encountered Ryoko Shinonome, who was under the belief that Sekigahara was 426 and the one who spread DD-426 to the other Sentinels. While inside Universal Control, Miura witnessed Tomi Kisaragi's contact with her counterpart from one loop ago. Eventually, the group returned to Sector 4.

Sekigahara was eventually forced to hide Miura's scout unit inside the girl's changing room in Sakura High Athletics Building while avoiding the men in black - Ida's subordinate, whom he sent after Sekigahara to keep up the facade that they are working against one another. Unbeknownst to him, Miura was aware of his true intention and erased the location of his Sentinel from his memory, save for a single clue.

When Natsuno Minami arrived to change before returning home, she found Miura, who uttered the words "BJ eleven five" before erasing it from his memory. Natsuno assumed that the scout unit is an alien running from the men in black and began referring to it as "BJ". After checking her innerlocitor code and finding out that she was a Compatible, BJ enlisted her help in finding his lost Sentinel, showing her the location of the transfer gate at Tokisaka Shrine.
