A second-year student at Mitoya High trying to blend in with the crowd. His classmate Hanadori makes this very hard, constantly trying to grab his attention and involve him in his fantasies. 

Seri Koyuki is just trying to have a normal school life, but instead he ends up acting as the straight man to his odd classmate, Kabuto Hanadori. Kabuto is a delusional high school student, whose fantasies range from believing he is a knight on a journey, to claiming that removing his eyepatch will release a darker alter-ego who he refers to as Michael Offenbarung Dunkelheit. Seri is determined not to let himself get pushed around by Kabuto, but it seems that this will be easier said than done!
