In a world where magic and monsters are real, a powerful archmage named Valen is betrayed by his closest allies and killed in a horrific ritual. However, he is reincarnated in a modern world, retaining all his memories and powers. A mysterious system called "The Arcane Codex" activates within him, guiding him on how to reclaim his former power and seek revenge.
Valen discovers that other individuals with magical abilities are drawn to him, each with their own tragic pasts and unique skills. These individuals, primarily women who have suffered in their past lives, are inexplicably connected to him and become part of his harem. As he builds his power and forms deep, complex relationships with these women, they embark on grand adventures across dangerous lands, fighting against monstrous creatures and dark forces.
