Shiro Fujimoto (藤本 獅郎 Fujimoto Shirō)

Shiro Fujimoto is a Catholic priest at the Southern Cross Monastery, a Paladin in the True Cross Order (the title awarded to the strongest exorcist), Shura Kirigakure's mentor, and foster father to Rin and Yukio Okumura. He was qualified as a Knight, Dragoon, Doctor, Aria and Tamer through his cait sith familiar, which he called Kuro. Shiro is a man dedicated to his duties and was considered the strongest exorcist. Stealing the demon-slaying sword Kurikara,[ch. 24] Shiro and Mephisto ultimately used the sword to seal the demon heart of the son of Satan and Yuri Egin. Shiro then adopted Yuri Egin's children, Yukio who did not inherit Satan's power, and Rin, full inheritor of Satan's powers.

Shiro is thought to be the only man in the world able to sustain possession by Satan himself and thus Satan was constantly after his body. He fights off Satan's attempts at possessing his body through sheer willpower, but after receiving a mental shock from Rin accusing him of "playing father" and not caring, Satan takes over his body.[ch. 2] After Satan summons the Gehenna's Gate to retrieve Rin, Shiro regains control of his body temporarily and commits suicide in order to stop Satan.[ch. 1] Because of this, Rin decides to avenge Fujimoto; he also considers him to be the coolest person he knows. He is voiced by Keiji Fujiwara in Japanese and Kirk Thornton in English, while in VOMIC he is voiced by Yoshito Yasuhara.[1] In the Blue Exorcist musical, he was portrayed by Yasuhiko Imai.[3]
