Rinne Higaki

A saint resembling a girl with long greenish, black hair who wears a long scarf-like cloth as clothing. In reality he gains the appearance and personality of those who see him and resembles those which they don't wish to remember. His appearance comes from Shichika and is a collaboration of those who he regrets losing to and his personality comes from Togame's memories. Rinne has lived for more than 300 years and was a friend of Kiki Shikizaki as he received Hakari through him. But fearing that the blade's poisonous nature he had buried it. He rather enjoys tormenting his company as they learn a little bit more about themselves through illusions until they eventually get Hakari.

He wields Hakari, a sword that lacks an actual blade. (Source: Wikipedia)
