Katsuo, a transmigrator reborn as a starving five-year-old Uchiha orphan, survived after crawling to a relief meal. After reading his mother's letter and resolving to grow powerful enough to return to his original world, he set out to demand his family's unpaid death compensation.

• Katsuo took a kunai and left home to confront the Uchiha clan over his father's unpaid death compensation.
