Jitsu wa Ore, Saikyou Deshita?

A twenty-year-old socially reclusive man is reincarnated into a world dominated by magic, seeking a quiet life as a shut-in. From birth, his magical potential is considered extremely low, leading his royal parents to abandon him. Despite these odds, the newborn prince survives in a dangerous world filled with magical threats. Unbeknownst to him, his actual magical power is extraordinarily high. As Haruto, he deals with various challenges, including demon friendships, royal conflicts, assassination attempts, a hidden superhero identity, and the presence of a younger sister.
