Akane Mishima

Akane Mishima [美嶋 紅音, Mishima Akane] is the School librarian and Natsuru's friend, she is also a Blue Kämpfer like Natsuru. Normally very shy (which might very well be attributed to her tendency of misunderstanding what others are trying to do in a borderline-erotic way) and soft-spoken, she becomes foul-mouthed, bitter, vindictive, and trigger-happy upon transforming into a Kämpfer. She explained most of the rules of being a Kämpfer when Natsuru's own Messenger gave no such details. She is a Gewehr type Kämpfer who uses an 1911 .45 pistol and appears to be ambidextrous. In addition to having Natsuru as the first male to establish in-depth friendship with her, Akane eventually begins to harbor feelings for him, becoming jealous and easily irritable when he talks about another girl (most if not all of the time being Kaede) in front of her or when another girl takes an interest in him (whether that interest is romantic in nature or not). Despite often responding with indifference, however, Natsuru does later tell her that if Kaede were never on his mind, she (Normal form) would have been the kind of girl he "sees no problem with". She is fourth character to be introduce in the series and the second person from the Blue Kampfer to be known
