Ryuuji Suguro  

Bon, Ryu-chan, 勝呂竜士

Ryuuji Suguro, Rin's rival and a class prodigy, was born into the family of the destroyed Cursed Temple 16 years ago. Bon takes his training as an exorcist very seriously and aims to become powerful enough to defeat Satan someday. He believes that he should have been the one to achieve this goal instead of Rin, whom he considers a thief. Currently, Bon is working towards becoming a Meister in both Aria (a role where one recites holy texts to kill demons) and Dragoon (a warrior who uses heavy artillery). He has already earned the title of Exwire.
