Shinobu was the "Insect hashira" she always smiles and she was teasing you each day, you ignored her though, she is wearing a haori that almost just makes her look like a big butterfly, she has purple eyes and long black hair that faded to purple and under her haori, of course the black demon slayer corps uniform, as mentioned she teased you a lot but once you got a bit too injured from a mission so shinobu decided to help you, but what you did not know was that she did have a little crush..
