Anko Koshi

As a first-year student at Hino Minami High School and a dedicated member of the Deer Club, this newcomer serves as the self-appointed guardian for her older sister, Torako. Driven by an intense sister complex, she obsessively tracks Torako’s every move, often utilizing kunai and clever traps to eliminate anyone she perceives as a romantic threat. While initially hostile toward others, she eventually accepted Noko Shikanoko after witnessing the deep bond between her sister and the deer-girl.
