Sotorii is similarly cruel & generally asshaty as his counterpart from the original timeline was. And him being that was a major driving point of the story.I cannot help but get the impression that one of those two princes is significantly more villainous than the other.
This time he even has a very personal reason to have beef with Toturi & cast him down when he gets an excuse!
Well... Given the Daisetsu / Daigotsu parallels (with his involvement with Sahai being a major one of those, actually)...I find funny Iuchi Shahai went from being the former baddie (Daigotsu) milf to the current Good Prince bestie.
Nevertheless, they're cute together & still Not Evil (tm).
