Takuma Arawaki

A delinquent high schooler who wroked part-time at a host club, Takuma unexpectedly inherits the mantle of leadership from his late father, Michizane Arawaki, as the 272nd head of the ancient Arahahaki Clan, a secretive group with roots stretching back to antiquity. Thrust into a world he barely understands, he finds himself fighting to protect Anastasia, a Russian girl his father had taken in, alongside his childhood friend Hideko Kondo and a group of allies.
