マジシャン

Synopsis

Since he provoked Yuki’s parents’ death, Shougo, who was acclaimed to be a genius of magic, abandoned the magic shows. He has hypnotized the little Yuki to make her forget this tragedy, and is living with her as her guardian (later as her lover ^^). They are often implicated in crimes and murders that Shougo succeeds to resolve, combining his reasoning to his skill of magician. source: mangaupdates
