The Bastard Hero

Lukas Belmont, waking up as the powerless, orphaned ward in a house of super-powered heroes, awakened with a system but his stats are still garbage. His only path to power is the Scumbag System which request him complete the "humiliating" quests. And so on, his first quest's to smack the ass of Sloane Fitzgerald—his fiery, super-powered psuedo-sister who sees him as a brother and a pervert in equal measure, and the penalty for failure is the reduction of his manhood permanently. Watch and see if an insect with a gacha system really can climb a ladder built for gods or not.
