Anyway, Yuta FRA.
Kenjaku’s Domain wouldn’t insta-break Yuta's as it also didn’t break Yuki’s SD. Kenjaku also said she’d have better chances with her own DE. Yuta has better barrier refinement then Yuki by feats and statements, and will obviously shrink his own DE once Kenjaku opens his, giving him more than enough time to use JL or any other CT/attacks that will avoid Kenjaku from being able to maintain his DE active.
Funny how everyone says that Kenjaku and Gojo are equal in hand-to-hand when that’s w/o CE, and referring to skill, which JJK isn’t that well known for and even the best fighters like Toji/Maki don’t have much to back them up. Kenjaku’s only hand-to-hand feats are Vs. Choso who, again, isn’t well known for, and a depowered Star-Rage Yuki. If it gets to the point of a physical combat, then the fight is effectively a 2v1 where Rika has enough strength to send Sukuna flying around Yuta’s DE and has enough LS to hold his arms still. Yuta will very likely use any of his Cursed Tools like the steel arms or the arms Yuji used that can withstand Sukuna’s Dismantles. And in combat, Yuta will also use Sky Manipulation to avoid getting hit, Cursed Speech to have advantage over Kenjaku and to get clean hits, and G Warstaff to predict his movements.
Again, Kenjaku’s only offensive CT is Antigravity System and it had a cooldown to be used, and it’s not lethal considering it was not killing/dealing heavy damage to anyone besides when it’s infused on his DE. Cursed Spirit Manipulation is completely useless as Yuta can very much handle any of them by his own, Rika can tear them apart since they’re pretty much shit, also RCT output from both Rika & Yuta and JL. Uzumaki has such a wide charge window that’s just not a real move for him to use. Try to use Uzumaki and Yuta will have like 5 different ways to finish the fight right there. Tiny Uzumakis also won’t work, Yuta has enough CE to constantly protect his body and has previous knowledge about it.
Kenjaku’s only real wincon here is his DE, and that’s not even something he’s actively using as his first move. Even if he does, Yuta will counter, and it will give him enough time to use any of his wincons that are much more certain than Kenjaku’s.
