椿木 泰之丞

Tainojou's nickname is "Bo", which comes from an alternate way to read "Tsubaki". He says it annoys him a bit, but everybody continues to call him Bo, even Sayori. He is rather androgynous and comes from a samurai family. 
He likes to dress elegant and to act the part of a knight (cape included). He complains about being a "chick magnet" and is very interested in the paranormal.
