Keidori

Keidori is the slash ship between Keiji Shinogi and Sou Hiyori from the Your Turn To Die fandom.

Canon
During the capture of a suspect, Sou was undercover as a police officer with Keiji and Megumi Sasahara. During the incident, Sou manipulated Keiji's lack of experience and told Keiji that the suspect was going to fire his weapon. Keiji, in the heat of the moment, listened to the disguised Sou and fired a gun. The suspect turned out to be a role model of Keiji's from his past. The trauma made Keiji unable to even touch a gun without panicking as seen in his battle against Midori.

Keiji's career untimely ended after a routine arrest, where he was misdirected by a disguised Sou Hiyori into shooting and accidentally murdering an "unarmed criminal;" none other than his childhood hero.

At some point, Midori collects Keiji's signature on the ASU-NARO consent form, putting him into the Death Game. Like the other candidates, Keiji's memory of this is supressed.

Keiji doesn't meet Midori until reaching the fourth floor during the Death Game. Midori triggers Keiji into a panic attack by showing him the gun that he shot Mr. Policeman with. Keiji is so enraged by Midori that he declares he will kill him and a battle ensues where Keiji tries to tag Midori. In the end, Midori pushes Keiji into his coffin and locks him in.

Fanon
Keidori is not as popular of a ship due to the way Midori treated Keiji.
