Satan has been driven back. The forces of Gehenna have been repelled (for the time being, at least). Class 1-A has returned to UA, and Rin has resumed his exorcist training at True Cross. Despite parting ways, things are going great. But, with the opening of the Gehenna Gate, demons are spilling through the cracks all over Assiah at an alarming rate. All whilst villains across Japan are rapidly starting to partner up with them. With heroes trying and failing to combat the growing threat, UA has only one choice - to summon some of True Cross's most-trusted exorcists in the hopes of severing the ties between villains and demons. Before both forces become far too strong to handle. It looks like Rin's time with Class 1-A is far from over. _ This story is a direct sequel to my previous Blue Exorcist/My Hero Academia Crossover: 'Hellbound'

Kill a demon. That was the only instruction given to Class 1-A before the students were sent on a mission to a school none of them have ever heard of before. True Cross Academy, a place for the incredibly gifted. And for the quirkless. Unlike anything any of them have ever seen, the class are instantly on their guard, and have little choice but to team up with none other than the school's faculty of exorcists. A small group harbouring a secret way bigger than themselves. Because, unbeknown to Class 1-A, their target is much closer than they've yet to realise. And Rin intends to keep it that way, for the sake of his own life. The son of Satan versus a group of superhuman teenagers. This should be fun.
