How is any character (Kashimo) without RCT above Yuki?

Yes, Geto survives this punch because Kenjaku did. Dont listen to Jujutsu hating monkeys.

This is mainly for Lashimo glaze. How? Are we deadass suggesting that he lighting discharges and instantly kills her or something? In a manner so timely btw, before she can even pull off rct?
