After his family perished in a gate-related tragedy, Dabi swears to protect his siblings and unravel the mysteries within these deadly portals. Alongside his loyal spirit pets and rare allies, Dabi faces ancient threats and powerful enemies tied to his parents’ tragic past. As he rises in power, Dabi’s quest draws the attention of noble families, dangerous royals, and sinister forces seeking control over dimensions and the future of humanity itself. Secrets, betrayals, and a growing vendetta lead him deeper into a battle that threatens the fabric of existence. With the fate of his world hanging in the balance, Dabi must outwit and outfight forces beyond imagination all while confronting the truths hidden within the gates of the lost dimension.
