Revenge Agent Hizumi-san

Masaichi Hizumi is a revenge agent, professionally dishing out just deserts to anyone who may have incurred the wrath of his clients. His latest target? Mikoto Kuga, an elite salaryman, narcissist, and way-more-than-two-timing cheater. Hizumi’s task is to teach this piece of trash a lesson—by thoroughly humiliating him, body and spirit! Whether he’s ready for it, Kuga is about to get his comeuppance, served with a smile by Hizumi!
