15 years before the present. Still a badass.
The Fifth episode of Ao no Exorcist: Kyoto Fujouou-hen (Blue Exorcist: Kyoto Impure King Arc) picks up after Rin gets knocked out. Bon’s father breaks the tension by patting Shura on her rear, not just out of an act of perversion, but using it as an opportunity to slip her a letter. Then he slips away as Yukio arrives and learns about the situation at hand while Mamushi, still under the belief that she’s doing the right thing, continues to flee with Todo despite the damage the eye is doing to her body because she put it in her head like an idiot.
So now both the Left and Right Eyes are taken and they figure that the pair will be used to unleash a more potent miasma. Yukio has his doubts because of how Todo confided to him, and then he learns that Rin flared up and everyone saw it. Since that’s the equivalent of a death sentence for him, he’s… less than pleased with his older brother. Shura still thinks Rin has the makings of a good exorcist because he’s so honest while Yukio is the sort who’s likely to give into the darkness unless he loosens up.
Then we cut to the Ex-wire girls having a moment, which gets interrupted when Shima arrives to inform them that Bon’s been hurt and Rin’s been thrown in solitary. Speaking of Rin, Yukio basically chides him for what he did before Shura hands him the letter Bon’s father gave her. The letter, which neither Shura nor Rin could read because it was in cursive, details how Bon’s old man knew their old man.
It turns out that before Bon was born and his mother was ill because of the Right Eye of the Impure King, he was a serious priest who cared about the people and teachings as the miasma ravaged their sect. That was when he ran into Fujimura while he was still a Paladin, capping demons with a rifle and stealing the demon sword that would house Rin’s flames in the future. That little tidbit naturally throws the Okumura brothers for a loop, but Shura encourages them to keep reading as Bon’s father races off and the episode ends.
So we have more character development and get to see Rin’s father, slightly younger and still badass. Considering that Bon’s father asks for Fujimura to watch over him as the episode ends, it’s clear that despite meeting like that something happened to put them on friendly terms. I can’t wait to find out.
