I hope it's time Yuji showed his true potential. Up to this point his feats in very fast growth was by far the best in the series, he worked so hard the month before the fight with Sukuna, right now he should at least be able to use his own/Sukuna's CT... And with his potential he might even be able to use Domain Expansion very soon. Well if Sukuna going to be defeated in this fight, Yuji has to be able to use all of the mentioned things. It's high time we fully comprehend that real Gojo's successor is Yuji and only Yuji, no Yuta's shit anymore, because he's boring as hell.
Yuji gotta beat Sukuna one on one. It would be the most humiliating scenario for Sukuna. Black flash is his thing but he's also the best at fast pace learning, he's really good with RCT now (and he learned it one month, basically he just learned it) and only Toji/Maki can top him with taijutsu. Maybe now he'll learn how to enforce his body with CT better and thus reach heights unavailable for even Maki or Toji, heights that only Sukuna could catch.
Yeah but it was due to Togashi just being plain and straight lazy. All of his manga's look like shit even though only few mangakas can hold candle to him plotwise. Dude should be writer instead of mangaka and draw only design of the characters. It's so sad he'll probably never finish HxH.
