Hunter: Red-Eyed Heir of the Zoldyck Assassins

Reborn as the eldest son of the legendary Zoldyck assassin family with crimson eyes and a mysterious system, our protagonist has no intention of following the script. While everyone expects him to inherit the family legacy, he has other plans—reshaping the Hunter x Hunter world according to his whims. With overwhelming power and a villainous streak, he'll dance through this dark new life as an unstoppable force. Genius? That title belongs to little brother Killua. This red-eyed rebel answers to no one.
