He is Rin's rival and the prodigy in the class. He was the child of the Cursed Temple which was destroyed by Satan 16 years ago. Bon takes everything seriously and is trying his hardest in order to become an Exorcist powerful enough so he could one day defeat Satan ( a goal he claims Rin stole from him) and rebuild his Temple. Currently Bon is trying to acquire the title of Meister in both Aria (a person who recites holy texts to kill certain demons) and Dragoon (a person who fights with heavy artillery). He is currently an Exwire. He is good at memorization, cleaning and Zen meditation. (Sources: Wikipedia and the Blue Exorcist volume two manga extras)
