Because I'm cryptic
Ok, it seems nobody understood what i ment so I'll explain:
There was fair assumption that there is no permament death in Kumon-mi. It was kind of implied when Maya explained resets and kind of confirmed by Bluejay. Kind of
1) As I mentioned far earlier, it was Makoto's fall from rooftop prevented so there is no link to return of people already dead
2) Maya had no idea what's wrong with Makoto. It is directly implies it was not something ususal
On the other hand, all creatures with confirmed death haven't return (I.e. todd, Makoto's dad). "There is no permament death" hypotises happens to be based on nothing.
This was a context. Now, to the facts I droped before:
There was a "plot hole" (1): Sensei's class is only 10/20 while Wakana already has almost full class.
Previously it could be explained only with ad-hoc (like it was Sensei's rokie year or smth like that, so he received special threatment). Hower, given that "initial" cycle setup may change between hard resets (2) and confirmed numerous cases of in-class homicide (3), there is "natural" explanation which does not require any ad-hocs: half of class are already dead.
I think, it is a direct call for Occam's razor. This what I was thinking about
