Fan Casting Akumetsu

Nagasawa Shiina is just an average high school student until her parents' company goes bankrupt. In order to pay the bills, she sells herself into prostitution. At her first job, a mysterious masked man crashes the party... and it's someone she knows. She recognizes him as her classmate Shou Hazama. Claiming to be "Akumetsu," he interrogates Japan's former finance minister about all the evil deeds the other has committed. He then proceeds to brutally murder the man and drag his body to the lobby. When Akumetsu is shot, he somehow blows his own head off afterward. A year later, Shiina goes on to live as a normal college student. But in a shocking turn of events, Shou Hazama, who's supposed to be dead, is attending the same university as Shiina. How is he alive, and what does he intend to do next?
Akumetsu is the story of Shou, a vigilante that's out trying to straighten the corrupt Japanese Government through terrorism with his "One man, One kill" code of action.
