Blue Exorcist

Humans inhabit the world of Assiah, while demons reside in Gehenna. Though these two realms should never intersect, demons still possess living beings in Assiah. Those who combat these demons are called exorcists. Rin Okumura is a boy cursed with the legacy of being Satan’s illegitimate son. When his foster father sacrifices himself to protect Rin from demons, Rin vows to avenge him and prove his worth by becoming an exorcist-and ultimately defeating his own father, Satan. To sharpen his untrained abilities, Rin enrolls at True Cross Academy, where he trains alongside other aspiring exorcists.
