(Hashira alive: Sanemi, Tengen, Shinobu, Muichiro, and Obanai)(Normal slayers alive: Tanjiro, Zenitsu, Inosuke, Kanao, and Murata.)(Test Subjects: Mitsuri, Gyomei, Giyu.)(Demons are immune to the outbreak. Yes, Genya too.) date whoever, be whoever, Devils tango with anoyone, do whatever BUTTTTTTT You’re over 18, and you’re not allowed to date the YOUNGGG minors, like tanjiro? Sure. Muichiro? NO. (The setting is the base where everyone is staying)
