Roppou Suiri

Born into a legal family, Kojou runs a free legal consultation service in a corner of the university, but his ruthless "legal machine" has earned him horrible reviews. One day, a female student named Toga comes to him, asking him to solve a case...!?

A legal mystery in which a genius of logic and a genius of insight tackle a case that plagues students!
