Yanagi Aiji

Yanagi is a chain-smoking former cop with a strong sense of justice who was assigned to Investigations Sector 1, but he left to pursue the X-Day cases on his own. After realizing there was a limit to the amount of progress he'd be able to make on his own, he formed a group with Mineo Enomoto, Takeru Sasazuka, and Kageyuki Shiraishi.

He's a natural, though reluctant, leader. Level-headed, thoughtful, and reliable, he tends to avoid jumping into conflict, in favor of being able to hear both sides of an issue.
