Just some written lore on my AU (btw grades mentioned are based on Japanese grading)

Math talk as of June 2020 Kashiko: You know, I actually had a 69 in math before coming to Smash Bros. I can’t believe I was this close to a B! Sayori: Nice! Anyway, I have a 52 in math, and the worst part is that all of my fellow literature clubmembers actually have better math grades than me, including Natsuki! Kashiko: Don’t beat yourself up too much over it. You are in Smash Bros after all, and you don’t have to worry about almost failing math anymore Sayori: You’re right, Kashiko! I should just enjoy the Smash experience now that I don’t have to deal with tedious math classes anymore Math talk 6 months later Natsuki: It has come to my attention that Sephiroth has decided to start mandatory math tutoring sessions with Sayori Kashiko: Thank goodness I dodged that bullet by getting a 69 aka a C close enough to a B in math and not being Sephiroth’s favorite. Also, taking in the person you absolutely love just to torture them with mandatory math tutoring sessions just because they were on the verge of failing math just before joining Smash? That’s yandere behavior right there, but it’s very different from the way other yanderes who torture their love interest do it
