Does anyone else kinda wanna strangle Touka?
Who ever is behind all the timeskips and resets is getting really sloppy!
I thought this was an isekai/possesion deal, but it seems that an errant reset caused massive memory loss in Sensei (probably multiple times).
Best I can figure is Sensei dated Niki, then some time later his brother died, Sensei took Ami somewhere else and raised her. Started teaching, then 'woke up' one time without remembering anything. Most of Sensei's knowledge came from the dossier book Maya left for him.
I can't place in the timeline when Maya 'stole' Sensei from Niki, was it before or after his brother's death?
Very rough timeline:
1) High school-aged Sensei dates Niki.
2) He gets injured, begins an affair with Ami's mother
3) He vanishes on Niki as he has fallen in love with Ami's mother
4) Some time later, Noriko finds him and starts getting tutored by him
5) Soon after that, Maya also starts getting tutored by him
6) Some form of relationship begins to form between Maya and Sensei
7) Ami's parents die
8) Sensei becomes a teacher
9) Something causes Kumon-Mi to become isolated from the rest of Japan and the cycle of resets begins.
