Fact is, the only person that interceded in the duel between Sukuna and Gojo is from team Sukuna.
And Sukuna didn't even chide him for it.
Though I agree, agendas can be put aside ocassionally.
IF (I insist on it) Sukuna is restricted by a binding vow, there's no team Sukuna. I'll wait for the proper translation, but so far Sukuna wanted to fight Gojo right there right now.
Still
IF there's a binding vow, Kenny postponed the fight, not Sukuna. Implying, in favor of Gojo, that Kenjaku isn't 100% sure Sukuna could win this. He (Kenny) prefers Sukuna to fulfill his task before fighting Gojo.
But yet Gojo accepted it, admitting he had things to do too before fighting him.
Let's say it's a 0 - 0 or 1 - 1 situation. Both sides had advanteges by postponing this fight.
Concerning agendas I don't have any. Agendas are toxic to me. I enjoy mangas as they are and has they're done. If I don't I stop reading.
Simple. My only "agenda" in any series is naively/childishly wanting the good defeating the evil chars. Cause I don't like evil chars. (Lmao)
