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.
