An academy where the worst scumbags rule.
About
A twisted academy where the nastier your personality and the better you are at stepping on others, the higher you rise.
Reigning at the top are a group of malicious young men. They seem obsessed with Fuzuki, who proudly calls himself a scumbag... or so it seems. In reality, the one they are truly interested in is Guest, the genuine, ultimate scumbag that no one else knows about.
Fuzuki, who believes he is the pinnacle; Katsumata, who longs to meet a real scumbag one day; and Megumi, who looks down on everyone—none of them know Guest's true nature yet.
In this school where hypocrites, narcissists, and the wicked clash, how will their relationships change when they face the most terrifying scumbag of all?
Guest is a bona fide, total scumbag. Everything else is up to you 🫶
