Ubau Mono Ubawareru Mono

Twelve-year-old Setou Yuu possesses a remarkably sharp intellect, yet his brilliance offers him no refuge from the relentless cruelty of his daily life. Trapped in a cycle of severe abuse at the hands of his violent father, he is further subjected to regular beatings by debt collectors seeking repayment for his father's obligations. The physical toll of this torment is permanently etched across his young body, leaving him covered in scars and stripped of any semblance of a normal childhood. His desperate existence takes an extraordinary turn when he is suddenly transported into an entirely different world. Far removed from the tormentors who defined his past, Yuu finds himself in an unfamiliar realm where the rules of his previous life no longer apply. Here, he finally acquires the very means he has always lacked—the power necessary to protect himself and those he holds dear. Armed with these newfound abilities, the once-deprived boy seizes the opportunity to strike back against anyone who dares to threaten him or his loved ones, transforming from a helpless victim into a formidable force determined to reclaim everything that was stolen from him.
