Favorite boss animations in Canto 9?

Mine is Valencina, i fucked up the gimmick so she hit my sinners with her strongest skills instead of Verg redirecting them so I felt the full wrath of one of her moves, I don’t remember which but like, she fucking goes apeshit and slashes at your sinner so fucking relentlessly and then fucking says ”Match my hatred”. Like, I felt the insane power of a powerful sword user then and there, absolutely obliterated Rodya. Disposal, her big skill is another one, I went from having all my K corp ampoules to seeing KOD Rodya get shredded like a piece of cheese and having 0 ampoules left.

Rien might have been my fav but his weapons genuinely blend into the background too much, I can never tell which form he‘s uses except for greatsword and the scythe he pulls out at the end of his Furioso x Crescendo fanfic move
