Rin Okumura

Summary
Rin Okumura is a son of Satan and an Exwire studying to become an exorcist at True Cross Academy. Initially growing up unaware of his heritage, he and his brother Yukio were cared for by Father Shirou Fujimoto. Rin ultimately lived a troubled, if relatively uneventful life until he began seeing black specks that no one else could perceive. This cascaded into a series of events that led Satan to possess Father Fujimoto in hopes of dragging Rin to Gehenna.

Left with little other choice, Rin drew the blade that sealed his demonic heritage in an attempt to save his adoptive father's life, but the latter had already committed suicide to protect Rin from Satan's influence. Swearing vengeance, he demands Mephisto Pheles to allow him to become an exorcist in order to defeat Satan once and for all.

Standard Equipment: His Kōmaken (Demon-Slaying Sword) Kurikara which holds his demonic abilities

Intelligence: Rin is not particularly bookish, being frequently criticized for his poor grades in and out of exorcist school as well as his reckless demeanor. However, his lineage has given him a natural talent for combat, and he has a great deal of street brawling experience due to protecting himself and his brother from bullies at an early age. In addition, his swordsmanship has greatly improved while under Shura's tutelage, allowing him to hold his own against demons much larger than himself and channels his otherwise volatile flames through his blade.

Weaknesses: If Rin's tail or his "heart" (the Kurikara) are destroyed, he will die. He's rather reckless and is sometimes foolhardy when he's riled up. He also suffers from deep-seated trauma and survivor's guilt from Father Fujimoto's death and is terrified of being abandoned.
