Well, this is really good idea, but it's more like one-time oporunity than pattern
Yeah, it'd only really work as a one time thing anyway. It'd lose it's affect and appeal if it's repetitive. I'm sure there could be alternatives though.
I can't say it is impossible, but it is definetly not what I expect Selebus would do. According to Maya, Sensei resets with so different personality that she cannot believe he is the same person. And also, he regains exclusively pre-reset memories which is not a big deal when full reset comes yearly and you already get used to it, but not when all your common story with somebody gets wiped. It is very big deal, which obliviously can be used to plot development, but would make coresponding route incomple. Call it a theory, but I doubt Selebus wants to disapoint us this way
Actually, there were a few times if I recall correctly, that Sensei seemed to recall memories from previous Senseis during the loops. Not just pre reset. One of these being a crying Maya giving him a handjob which seemed to be how a past Sensei broke. Of course, I could be wrong, and even then this could be something only Sensei could do.
There's also how Tsuneyo has seemed to recall previous resets, but she's an outlier for sure.
There are per-girl endings and mysterious "True ending" anounced. At least i been told that
Endings are far ahead, we are at the end of first phase and they are in the end of third. I don't think Selebus planning or capable of serious plot diverging at this point. It would be hell of work
I'm hoping the girls get more than one ending each, but I can be rather greedy. Either way, I'm looking forward to them, and whatever plot diverging shows up.
I honestly wouldn't mind if Sel milked the game after it ended and kept on adding new endings or "secret resets", etc. As long as the characters aren't suddenly written as shells of themselves, and the story isn't full of plot holes, I'm in.
