Flames of the Hell Spawn

A blue exorcist fanfic
I do not own

The enemy of my enemy is my friend... Right?
What happens when a simple exorcist training mission goes wrong? Yukio and his team of exwires, except for Rin, are cocooned in a spiderweb like substance. Nothing can seem to penetrate the substance, not even Rin's flames. three hundred and fifty years later, exorcist find a way to break the casing and free them. But when Yukio, Shura and the exwires wake up the world the knew is gone, and why will none of the exorcist tell them what happened to Rin? What happens when the Rin they knew is also gone? And who is this new enemy that threatens both human and demon?

Not a crossover I just really like the name Ente Isla
