Is the title a reference to the Monogatari series? I haven't read it yet and I can't remember if Araragi said that in Bakemonogatari (I need to watch it all).
I'm 90% sure that they're gonna be childhood friends or something similar and he just doesn't remember them meeting. Wouldn't surprise me if he had saved her from a car when he was a kid, like she did to him in ch 1.
@SomeGuyWithHair yup it is, can't remember exactly when, but I think it was during the Senjogahara arc.
@Piuther Yeah it’s really weird lol. Seven Arcs didn’t even animate the already existing Danganronpa anime. Maybe the author just requested for the show to have a lot of pop culture references? The show and this manga aren’t afraid to use and reference licensed stuff in this work at all, so it’s pretty funny to see lol
