(Tokyo revengers cats x a Tachibana) Naja Tachibana. Twin sister of Naoto Tachibana. Also a detective and works in the police department. It all started on a dim, foggy late afternoon when Naja got home. Deciding to take a quick nap, she woke up to the ringing of her doorbell. Walking up to it she looked around until she realised a box sat in front of her. Bringing it in she warily opened it to find...... kittens! Taking care of them was no easy task. Taking care of some thugs? Easy. Taking down a criminal organisation? Done that. Taking care of cats.......... well.... everyone needs to learn something new. Especially when those kittens were delinquents.
