I love TSUBAKI!! club.

If you love a girl who turns into assassin wepons then this is the club for you.She is Black Star’s Dark Demon Blade partner. She can change into multiple ninja weapons (shuriken, smoke bomb, a katana, etc). She is most of the time disheartened by Black Star’s loud self but she still puts up with it because that’s what she likes about him. She has a very forgiving personality and always tries to help everyone even when she has no idea how to help.Tsubaki soul is “very co-operative and has a lot of space to accept people” as said by Dr. Stein......oh yeah and her brothers an butt hole.
