Dagruel, the Earthquake, commands fear as a member of the Octagram and a prominent Demon Lord. His domain is the western Barren Lands on the Magic Continent's central continent. Born from the fragmented Wicked God defeated by Veldanava in the mythic age, Dagruel and his brother Glassord renounced their inherent evil. Their brother Fenn remained wicked and was sealed. Veldanava rewarded Dagruel's redemption with land and the vital duty of guarding the Heaven Tower to prevent Fenn's release, a role shaping his early existence. He presents as a middle-aged man exceeding two meters tall, with piercing blue eyes, slicked-back blue hair, and three distinct teardrop tattoos on his face. In battle, his size can expand tenfold. His Asura form stands roughly sixteen meters, magnifying his formidable presence. Contrasting his appearance, Dagruel demonstrates keen observation, wisdom, and calm. He deeply values his subordinates and family, evidenced by granting Dino centuries of free lodging and sending his three sons—Dagura, Liura, and Debura—to train in Tempest under Rimuru's care. This decision reflected trust in Rimuru's benevolence and a desire to discipline his sons safely. He holds profound contempt for betrayal, exemplified by his outrage at Clayman eliminating his own subordinates. His relationships are complex. He formed a close bond with Twilight Valentine, but Twilight's death at Luminous Valentine's hands shattered this friendship, triggering prolonged territorial conflict. Dagruel married Kisara, Twilight's creation, and fathered three sons. Kisara died in childbirth, and Dagruel later sealed her sibling, Basara, after a rampage. He maintains a sparring partnership with Veldora Tempest, their repeated draws fostering mutual respect. Dino resided with him for years until expelled for laziness. Dagruel's territory suffered devastation during a clash between Milim Nava and Guy Crimson. Containing the aftermath, he expelled energy into another dimension, but residual leaks created a lethal desert and sandstorms. This environmental catastrophe caused food scarcity, intensifying his rivalry with Luminous over her fertile lands. He joined the Demon Lord council partly to address these resource struggles. Dagruel wields immense physical strength and magical power, rivaling True Dragons. His base energy potential exceeds 40 million EP, surging to nearly 120 million EP in his Trinity form. Key skills include Soul Break, shattering souls and preventing revival; Magic Interference, nullifying magic attacks; Titan's Skin, granting extreme physical resistance; and Elemental Resistance, neutralizing elemental attributes. His signature techniques are Tidal Wave, Ashura, and Quasar Break. He also possesses True Sight, enhancing combat perception. During the Great War, Dagruel betrayed Rimuru, allying with enemy forces to lead giants against Luminous' territory in Luberius. Neither Luminous' strongest assaults nor Shion's evolved capabilities—including her Ultimate Skill Tyrannous Lord Susanoo—could decisively harm him. Veldora Tempest intervened. Dagruel fused with his brothers into his true form but was ultimately defeated. Post-battle, he dedicated himself to healing his land, using his magicules to restore vitality to the Barren Lands, and entrusted governance to his sons. Dagruel's unique nature prevents evolution into a True Demon Lord, his pure essence rejecting the Demon Lord Seed. This distinction, alongside his role as guardian of the Heaven Tower, underscores his significance in the world's balance.
