Well, looks like Kugaha took Kurama too…Damn! That makes things trickier for Yato. Oh yeah, and Yato seems to believe, quite understandably so, that Hiyori was kidnapped under Bishamon’s orders, rather than Kugaha acting alone. Let’s just say Yato gets a little hot-blooded the moment he knows Hiyori is in enemy hands. He’s going to get her back; nothing else matters. When Yukine hears what’s happened, he’s quick to join.
It’s a race against time, as Hiyori can only survive so long outside of her body. But she and Kurama are stuck, so it’s as good a time as any to explain the beef between Bishamon and Yato. Turns out, as we more or less knew, Bishamon’s entire cadre of regalias were wiped out by Yato, and Kurama was the only survivor. But Kurama also lets us know how a God can be resurrected after being destroyed, which is what Kugaha’s aim seems to be.
Kugaha wants Yato to kill Bishamon for him so a new Bishamon will be born: one he’ll be the exemplar for (rather than Kurama) and will likely be able to mold into more compliance than the current, “spoiled” Bishamon, whom Kugaha also believes is too “soft-hearted” to carry the mantle of God of War. And he may not even be wrong.
Thanks to Tenjin, Yato and Yukine are able to travel to the realm of Bishamon’s mansion (in exchange for being kept out of it, plus one other thing Yato understands without him saying), and the fight begins. Because Kugaha is basically using Aiha’s corrupted body to weaken Bishamon, the lack of a steady exemplar like Kurama means her power flies out of control easier, which results in tougher attacks but at a risk to herself and her regalias.
Trapped in a dungeon and unable to intervene even if “Veena” heard him, Kurama laments the fact that it was he who got his fellow regalias wiped out by Yato. That’s right: Yato wasn’t only a rabid monster killing indiscriminately (though he was certainly in Nora’s thrall at the time): he was a rabid monster killing indiscriminately because he was asked to, by a young Kurama who didn’t know what else to do.
When Bishamon’s body became riddled with corruption, and the regalia culprit wouldn’t come forward, discord was sown among them all, and all it took was one spark from someone who’s lost their temper to start fighting amongst themselves. Kurama couldn’t bear to watch Bishamon be destroyed in the chaos, so he exercised the nuclear option: hire a calamity god, Yato, to cut out the rot, to save Bishamon.
In the present, Yato seems to sense Bishamon is corrupted again, but Bishamon insists none of her regalias are betraying her this time—words that make Aiha tear up, because she and Kugaha are betraying her. In the past, Kurama’s quick, decisive action saved Bishamon, but I don’t think Bishamon wanted to be saved that way, even though things had gone to far to save her regalias.
The collective pain of their fighting and deaths would have probably destroyed her, but better she die than watch them die. It’s the reason she takes on every lost soul she can, even if they’re not useful. She blames Yato, but she blames herself just as much for what happened.
Now, things are on the verge of going past the point of no return, and everything is going according to Kugaha’s plans, with Yato and Bishamon fixed on one another and their colorful pasts, unable to see the forest for the trees. Vastly outnumbered, Yato gets separated from Yukine, is encased in a tripartite barrier, and Bishamon’s killing blow for him is caught by Yukine, shattering him into pieces.
This was a brutally intense episode culminating in an equally intense cliffhanger. I can’t quite believe Yukine is dead, since that would surely be curtains for the unarmed Yato, but who knows? It’s a very unfortunate situation. Kugaha has truly made a mess of things, and it’s going to be interesting to see if and how it’s cleaned up.
