They are bitter rivals who refer to each other not as "good rivals" but as "evil rivals." He is an extreme weapon otaku, giving girls' names to his firearms and treating them like lovers. He deeply respects the master musketeer, Shosei-san. Committee Chairman Monjiro Shioe is one of the few people he is genuinely terrified of. His bangs flow to the left.

His roommate, TakiYashamaru, claims to be able to read Kihachiro's emotions despite his blank face. He has long, wavy hair that clumps together in several distinct, tangled locks.
