Takumi Hijirihara

Takumi Hijrihara is a member of Future Foundation and is part of the 6th Division's Special Case Bureau as an investigator. Takumi's title is Killer Killer.

Despite being an investigator tasked with catching criminals, Takumi has a very strong appreciation for murderers and killings, which may have transpired from the traumatic experience of the Giboura Massacre. He studies murderers and even goes as far as to rate their crimes. Takumi's ultimate resolution is to emulate the killer he narrowly escaped from as a child.

While he was younger, his eyes were yellow not dark red.
