Shiiiit, they look awesome. Kishi did a better job on Itachis design imo
I don't know about Shisuis, but Itachis is going to be a beast. A perfect Susanoo wielding the Totsuka blade and yata mirror is pretty much invincible. Luckily for Itachi tho since this is a game or otherwise he'd probably die from just activating it lol.
