Haunted by years of female bullying that left deep emotional scars, the protagonist watches his childhood sweetheart get married and realizes he has been stuck in the past. Desperate to redo everything, he mysteriously time-slips back to his preteen body while retaining his adult consciousness and memories. Armed with knowledge of the future and zero hesitation, he begins a twisted campaign of sexual revenge against the girls and women who once tormented him.

First he targets his next-door neighbor Sera and her attractive mother, turning their past cruelty into total submission. Still unsatisfied, he moves on to his older sister Saki and the group of female classmates who bullied him the most. With each conquest he grows bolder, mixing childish innocence with adult perversion to break their minds and bodies. But as the line between justice and pure lust blurs, the question remains: when the revenge is finally complete, who has truly changed — the women he punishes, or the man who can no longer stop?
