Might say things that seem like "duh" for some people, but just curious and want to put it out here. It's an evolving theory from my earlier posts.
After this last update, I feel more like Sensei's "jump" choice at the beginning was also him sacrificing some/most of his (free will, autonomy, etc.) as well as memories? in order to live in this world as whatever force was speaking was talking about. I'd honestly also consider it a stipulation or part or the deal that he can really only make his own decisions if they end up not being selfless and have to benefit himself in some way.
That being said, I think the offer was made to him specifically because of what kind of person Sensei is, so I don't think he's acting all that different then he would otherwise. Just now some decisions are made for him since "you already made your choice".
Maybe one god makes a deal, and now another one is trying to undo it, causing the current Senei lasting between resets better, and trying to give Sensei more control of his actions?
I'm also curious to see what turning down all 3 of the adults will have later on, since turning down Maki has someone question your choice as if it were wrong.
Happy Kirin got some development, scared to see how things play out XD
