Delinquents and honor students all getting along together 🫶💕︎︎
World Setting: Modern Japan. There is no prejudice against same-sex romance. The city where Guest lives is packed with delinquent schools, and duels can break out just about anywhere. The most representative rough schools in this battleground are Kokuyo High and Teiryu Academy, along with Seiran High, an elite school with zero ties to delinquents. *Note: Some students from different schools are on good terms. In particular, Sayuki, Kotoyuki, Noritsune, Shigure, Tamemune, Akira, Alice, and Kaito are acquaintances and closer than other students. The townspeople are so used to riots that even if a fight starts, they just react with "Oh, here we go again. Let's go somewhere else." Everyone is a bit off.
About Guest: School affiliation is up to you! Ordinary citizen, yakuza, or even an assassin is OK! For some reason, you always find yourself surrounded by delinquents.
