The tenth episode of Ao no Exorcist: Kyoto Fujouou-hen (Blue Exorcist: Kyoto Impure King Arc) continues with the Impure King bursting like an over-sized zit and miasma spreads within the barrier, covering those within in a dense spray. The only reason it’s contained is because Bon has the barrier in place, a fact that angers the Impure King as it takes form in a fantastic sequence that shows just how massive it is compared to Bon and Rin. Every step making the spores billow out like the waves of the ocean as their headmaster watches on in amusement, clearly not intending to help.
Meanwhile, the monks inside of the barrier are forced to retreat before they can be overwhelmed, with Kinzo needing to be dragged away because being hot-blooded does not make you miasma-proof. The other group facing off against Todo find themselves also at a disadvantage since Todo is essentially a high-level fire demon and can absorb their flames, due to how the elements work when it comes to demonic hierarchy. Add to that the fact that he has regeneration from Karura, it’s basically a one-sided slaughter.
At least until Yukio comes up with a plan. They chuck fire at him until his body can no longer contain it and thus explodes out in a huge flame. And while he gets up from that, his body has turned to ashes and is thus dissolved by the falling rain. They go off to get reinforcements to take his body parts and store them away before he can regenerate, but the bastard manages to knock them out and then continue to troll Yukio.
Shima and Konekomaru finally manage to regroup with the group that managed to get outside of the barrier and tell them about Bon setting the barrier with Rin while Bon’s father is being treated by the girls. Shura tells them they did good work and goes ahead to try and help Rin and Bon. At the same time, Izumo is on the verge of being swallowed until Shiemi has her Green Man cover the thing in different anti-fungal plants to slow it down, despite it taking a heavy toll on her.
Bon and Rin take up the last few minutes of the episode as Bon has Karura protect him using a part of the barrier. However, the double spell will wear him out quickly and drop the barrier once he passes out in less than fifteen minutes at best because his body is at its limit. He tells Rin to get out and make sure everyone is okay, but Rin refuses despite the fact that he still can’t draw his sword.
It’s only when Bon decides to put his faith in Rin entirely as a friend and sacrifice his personal safety that Rin manages to draw his blade. His blue flames consume the Impure King with a single slash, albeit that’s not enough to kill it yet. So Rin prepares to go round two as the episode ends.
So, we’re closing in on the final stretch of this adaptation as things begin to turn around somewhat. Rin has drawn his sword and can at least present a challenge to the massive demon and Shura is there to back him and Bon to prevent things from getting worse. On the other hand, Yukio’s decent plan has failed to work because Todo refuses to relinquish his role as the main troll of the arc easily.
I’ve also noticed how the animation gets really dark during the flashier parts of the episodes, like when they used massive flame attacks. Not sure what that’s about, but other than that it was a decent episode.
