When his adoptive father, Shiro Fujimoto is killed by his biological father, Satan, Rin Okumura swears to become an Exorcist to avenge Shiro's death by essentially declaring war on Gehenna. Much later, whilst the preparations for a festival which is celebrated once every 11 years in True Cross Academy Town are being performed, a "Phantom Train" goes berserk—the barriers protecting the town from Demon intrusions are under repair. Rin, Yukio, and Shiemi are sent to exorcise the Phantom Train, but Rin manages to complicate the situation. Amongst the chaos, Rin meets a Demon in the form of a young boy. Meanwhile, Cheng-Long Liu, an Upper First Class Exorcist from the Taiwan Branch, joins Shura in the repair operation; as their paths all cross, fate takes its course.
As far as we know there are two new characters introduced, Usamaro and Cheng-Long Liu.
The young demon Rin meets in the Phantom Train subjugation mission. He seems to be sealed in a shrine for an unknown reason. He is looked after by Rin during the festival. He is voiced by Rie Kugimiya in Japanese and Cassandra Lee in English.
