Anko Koshi

135
Anko is best known for her sister complex towards her older sister, Koshi Torako. Though, it is yet to be explained how this came to be, she admits to being highly obsessed with everything regarding her sister, from her worst traits to her best. She makes it her personal life goal to be always by her sister's side 24/7, much to the latter's dismay and embarrassment. She will not hesitate to try and outright assassinate anyone who goes as far as to even just stand within near proximity of Torako, which even the latter can't even convince her to stop herself. The only time she makes an exception to anyone else getting close to her sister was when she tried staking Noko with a kunai to the heart, only to see, much to her surprise, that her sister deeply cares for Noko, and has decided that someone else, for once, was also worthy of supporting Torako together, side-by-side. However, if her sister is around or not related to the matters at hand, Anko is reasonable, kind, and gentle. She have a skills like a ninja. Anime: My Deer Friend Nokotan
