As it turns out, Daikoku’s borderline was only a precautionary measure to protect Kofuku; he allows Hiyori (and only Hiyori) to enter the shrine and shower in the spring water. But there are only two ways to cure Yato: if he himself slays the increasingly corrupted Yukine (something he won’t do) or if three regalias combine their powers and initiate an ablution—the confinement and punishment of Yukine until he confesses to his sins and repents. It’s a neat concept: only regalias can fairly judge other regalias, since they were both human at one point.
But first, three regalias are needed. Daikoku, setting aside his dislike of Yato for Kofuku and Hiyori’s sakes, visits every shrine in the area begging for volunteers. Mayu is the first who agrees to help, an interesting gesture that almost suggests a smidgen of guilt harbored due to making Yato release her from his service—or maybe just because her distance from Yato in Lord Tenjin’s employ has led to a gradual dissipation of the hatred she felt for him when they parted ways. Even regalias need a cooling-off period. That leaves one more regalia required, and while Hiyori’s pleas for Kurama were initially ignored, the debt he still owes Yato moves him to volunteer as well.
That’s a good thing, because we were worried for a moment there that Hiyori would seek the help of Nora, which was bound to cause more trouble than it solved. So with the three unlikely regalias joined, the final piece of the puzzle is Yukine, who is steadfastly unrepentant and believes himself unworthy of the punishment they start to dole out. It’s an uphill battle, as he nearly transforms into a phantom, nearly wiping away the mark of the name Yato gave him. Yukine isn’t guilty so much as angry and resentful that he can’t interact with people of the near shore anymore. Yato knows he has to call out to him, but is weak and needs time to gather himself to say the proper words.
He gets that time thanks to the person without whom he and Yukine (and possibly others) would have died long ago: the tough, resolute, dependable Iki Hiyori, who throws herself into danger yet again to make a personal appeal to Yukine. She snaps him out of his near-calamitous tantrum with the threat that they’ll no longer be friends if he completes his betrayal of Yato. That threat assumes Hiyori is his friend, something he’d never considered. Now that he knows he has friends, he repents and is purified. The final scene is replete with raw emotion appropriate for the aftermath of such an ordeal. When Yato and Yukine bow their heads to Hiyori in apology and gratitude, all she can do is gather them in a big ol’ hug.
