Yeah the school never sank before but Maya said there were times when noriko just happened upon him in his daily wanderings and they reconnected that way. It's a big city and sensei goes where sensei wants. Two events come to mind and that is the one where sensei is alone with Maya asking her why she freaked out on noriko the first day and the beach event where Maya is passive aggressively insulting her every chance she gets. It was one of those two scenes I believe Maya says that.
Its chp2 "Goodnight".
Summary is that:
Noriko knew back then that Maya and Akira had a "fucked up relationship".
Noriko accuses Maya of forcing Akira to leave Niki and Noriko both times.
Maya denies that but thats to be taken with a grain of salt i guess because
A) Maya was afraid Noriko might ruin what she had with Akira (by spilling the beans or stealing Akira maybe) and
B) That Noriko could have caused Akira to spiral back into depression mode again by being a connection to his past, this time maybe making it impossible to "fix" him again.
So what i was off here with, is that Noriko doesn't seem to have done anything wrong, just Maya being afraid she could have.
Thanks for the pointer and looking up!
After going through
What It Meant to Be Destroyed, there is only only a vague sentence "She (Noriko) has a long history of getting in the way", which to me still isn't clear enough to outright confirm Noriko really did run into Sensei before by sheer accident and right off the bat spill too much beans that killed him (which isn't entirely impossible). The
getting in the way can be roughly applied to the tutor time love tug-of-war and not reset-related matters.
Then I checked
What Is. Maya claimed that "Noriko can ruin everything much quicker than you think she can". But when Sensei countered with "how you would know that if it's something you never dealt with before", she admitted that she was just scared. Of course,
something you never dealt with before can simply mean
Noriko arriving to the school, but through context it can also mean
Noriko actually breaking Sensei using the same way Maya did. Despite the tendency of hiding things from Sensei, I don't Maya this time is hoarding information because this is something she can just outright tell him what exactly happened before and make her all the more convincing
The fact that Maya always and only rationalizes these with "the more you know the more difficult it will be" every time, instead of just flat out "did you know that Noriko once broke you in Tojo Ramen after accidentally bumping into you there and not shutting her whore blabber mouth up" kinda indirectly indicates that you don't need to have done something to have Maya consider you as a threat; you just need to knows a certain past too much (unless Maya going into details telling Sensei how Noriko broke him before BREAKS him now
).
Finally after going through
Goodnight, I think Maya might just be exercising extreme preventive measures in protecting Sensei. Maya knows well (or she thinks she knows) what can break him maybe after a few loops, and realizes that there is another person who is oblivious about the reset but at the same time is fully capable of breaking him. Thus, Maya took no chances and tried everything to keep her away, and might've been successful so far until now. When she saw the unstable pink bomb she's been trying so hard to avoid suddenly arrived at the doorstep, her frustration and personal prejudice from the past merged and overcame her.
