Aye for sure! I love this side of Hiyori in them, her expressions especially too! I feel she would potentially get along well with Bruunhilde from Record of Ragnarok as both of them have had to play similar roles of having to endure absolute nonense, tyranny, corruption and BS in general and put on that old fake smile and poker face, whilst conspiring against their tyrants in secret. Also Bruun has absolutely h ilarious expressions, which these Hiyori arts remind me of too hahaha!:
Its a shame the arts had to come from a YamaHiyo shipper as you said, I realised afterwards that's who they're from unfortunately, it made my skin crawl when I realised lmao. So many things wrong with that and to unpack but I won't ofc lol.
I'm so glad at how Toei really did her justice in her iconic moment recently vs Orochi though! Can't wait to see how they handle her end of arc scenes too! That grand speech and everything ofc!
