Shiori is what you call a 'White Spirit'. The difference between a White and Black one is how they are made. White spirits are born that way and have ghost like tendancies. Black spirits are the human spirits that have died and haven't passed on quite yet. This happens to be the girl Ro falls in love with. She's sweet, soft spoken and very kind. She is like Hinata from Naruto in a way. She has 12 CREEPY brothers and sisters and she is one of the middle children.
