Tsubame Otorii

Birthday: June 6

A mostly stoic girl with a very twisted view on friendship and no concept of family. Brought up by Cigogne as a special catalyst for the return of the Primum Mobile, she is isolated from society all this while. Hibari befriends her and will later either straighten or change those views. Also she's adopted by Hibari's parents. Her Pata-Pi is Petit-Ange (プティアンジュ Petianju), one which is basically dumb; it transforms into the Diva Erinnus. Tsubame's name literally means swallow.
