Nanami's eyebrows raise. Copying other people's abilities? It's the jujutsu sorcerer equivalent of curse manipulation. Powerful shit indeed. The flexibility that allows, with that vast pool of cursed energy Okkatsu has, is... unfathomable.

"Can you copy Gojo's abilities?" Nanami asks. Gojo may have lost to Sukuna, but he's still the strongest sorcerer of their age... at least until Okkatsu fully develops. If he can utilize Gojo's strengths, then they may stand a real chance of winning.

"Thank you for telling me." That's a huge revelation. It's not a binding vow, the way Nanami revealing his technique is. Okkatsu doesn't need one of those.
