@ striker10, what i meant was a odea about timeline in volumes 25. specifically arround the end of the preliminaries. just checking how much left for issei to graduate from highschool.

for example: at the end of vol23, chapter "new life", part 2, when match between vali vs rias was annonced, it was mentioned that 1st trimester was already over.
