Not Normal Arc: Return of the New Century Galaxy Legend! O Armored Hero, Stand upon the Earth!.Hifumi's dying words leave most of the students convinced that the culprit is fortune teller Yasuhiro Hagakure, who is found by Kyoko near the pool stuck inside the aforementioned robot costume. Yasuhiro denies committing any murders, claiming he was knocked out after being called by a note, which had subsequently gone missing. After Makoto and Kyoko finish their investigation of the crime scene, the class trial begins. Makoto starts vouching for Yasuhiro's innocence, using evidence to point out he couldn't have designed the outfit, let alone carry the corpses whilst wearing it. After Kyoko asks the court to consider the two murders as separate incidents, Makoto deduces that Hifumi had only faked his death from before, with Kyoko's evidence revealing Hifumi was the one who killed Kiyotaka, moving his body to the art supply closet, where he himself was killed. Tasked with finding the true culprit behind both murders, Makoto accuses Celestia of the crime, as she knew there was a second victim before it was announced. As Celestia grows defensive and brings up Hifumi's dying words again, Makoto deduces that the 'Yasuhiro' he was referring to was actually Celestia's real name, Taeko Yasuhiro. Accepting defeat, Celestia reveals that she stole Alter Ego to coerce Hifumi into killing Kiyotaka under the premise that they would escape together, before killing him herself in the hope of winning the reward money and buying a castle. Leaving Kyoko with the key to Alter Ego's location, Celestia is put through a Versailles-style witch burning before being run over by a speeding fire truck. After the trial, Kyoko has Makoto investigate a hidden room behind the boy's toilets, where he finds a whole bunch of confidential records and a note reading "You must not escape from here". However, he is suddenly knocked out by a mysterious assailant, discovering all of the files missing when he regains consciousness. Whilst returning to his room, Makoto spots Sakura and Monokuma squaring off against each other in the gymnasium.
