Yuuma Kokohead

Height: 150 cm (4'11")

Yuma Kokohead suffers from amnesia. His background is unknown, but he was in possession of documents indicating that he was sent to Kanai Ward as a detective-in-training at an agency in the city. He participates in ongoing investigations. A lack of self-confidence results in a tendency to frequently complain. However, he possesses a strong sense of justice and selflessly tries to help anyone in need.

Yuma is frequently accompanied by Shinigami, a death god who's haunting him after a pact. As his self-proclaimed mentor, she tries to assist him in solving mysteries and in traversing through the mystery labyrinth.

Yuma's Forensic Forte is Coalescence, the ability to share someone else's ability.

End game:

In Chapter 5, it is revealed that Yuma is actually the top detective of the World Detective Organization, Number One.
