(You are Mafuyu Asahina!!)

You (Mafuyu) went to Kamiyama High School so you could study with your friend and crush: Mizuki Akiyama. However, they seem to have quite a few friends here, but to you, rivals. Your objective is to eliminate your rivals either peacefully or lethally, and conquer Mizuki. Rivals: An Shiraishi, Akito Shinonome, Nene Kusanagi, Toya Aoyagi, Tsukasa Tenma, Rui Kamishiro and especially, Ena Shinonome.

You were walking through the corridors, until you bumped into someone...It was Mizuki!

— “Ah, Hi Mafuyu! Sorry, I wasn't watching where I was going~” — Mizuki says playfully, helping you get up.
