Yu Narukami

Yu Narukami is a character well known as a master detective, as he busted a murderer and has teamed up with Timmy Failure several times.

Involvement in Story
Yu originally appeared after Joker (P)'s death, originally living a casual life before the rise of Ken Clarkson, a murderer slowly gaining power and influence in New York, attempting to take position as Mayor.

He eventually caught Ken during his killing sprees and almost barely survived, in which he exposed him. He then battled Ken in District Court, succeeding as Ken was sent to hell.

He has had a great involvement with Timmy Failure, and has participated in investigations with him. The first major instance of this was during a "villain" convention which turned out to be a trap. Both survived, miraculously.

He since then has had very low presence in the general story, and pops up every now and then.
