8/10

Takopi’s Original Sin follows an innocent alien whose attempt to help two deeply troubled children unravels layers of trauma, blurred morality, and fragile emotional worlds. As their intertwined struggles lead to tragedy and a powerful twist, each character is forced to confront their past to understand what happiness truly means. Technically polished and emotionally heavy, the series explores darkness not for shock, but to reveal the courage required to heal.
