If Hikaru is a monster by the letter, then Yoshiki is a monster by nature.
This selfishness, this repulsiveness that he shamefully hides under a veneer of aloofness, is nothing but what he truly is at his core. For the longest time, he has made his absolute best effort to pretend otherwise, to turn his face from the truth, to portray himself as anything but what he truly is.
But by the same metric that Hikaru isn't the same friend he spent his whole childhood with, Yoshiki is nothing but the culmination of everything he tries to conceal, and regardless of how much he tries to deny it, he knows himself better than anyone.
And if he can believe that there's salvation for a monster like Hikaru , then surely there must be salvation, too, for a monster like Yoshiki.
Or: TSHD/JJK Crossover - Nobara and Megumi are sent to Kubitachi to exorcise a Curse and cross paths with Hikaru and Yoshiki.
