"The future huh... I've never thought about it" says the pre-cow-gnition yokai. Sus.
Tanaka sensei, you can't keep merging the main and spinoff timelines! I swear, if it weren't being fantranslated, I would be so mad (tysm)
But uh. I'll be real, I'm concerned about how long "as long as she physically can" will be. Not that it will not be long enough, but that it will be too long! These guys have gotta go up a year eventually! And even if they just swap out some characters, they have to graduate eventually too! We can't keep having long arcs that last a year irl but only a few days in-universe!
