Dagruel

Dagruel (ダグリュール) is a Demon Lord from the Giant race and the fourth seat of the Octagram. His territory is comprised of the Barren Lands at the westernmost part of the central continent.

Appearance
His eyes are bright blue and his hair, a marine blue color. Dagruel has three tattoos on his face resembling long teardrop-like lines at the center of his forehead in a vertical fashion and two below his eyes running over his cheeks in the direction of his sideburns.

His 2-meter height and muscled solid body plus his tendency to never mask his aura give him the appearance of someone capable of shattering mountains with his bare hands.

Personality
At first glance one might think this Giant is a brawler, and they would be right; however, Dagruel has shown an observant personality where he makes small polite comments full of reserve. He is calm and sure of his strength, and his quiet confidence doesn't blind him to the subterfuge present within the Octagram, actively seeking evidence to corroborate Clayman's story.

He appears to respect the power of others while still being indifferent to their lives, having fought to the death in many occasions with Veldora Tempest even as they always ended in a draw. He would aslo constant butt heads with Luminous Valentine because of their territorial frontiers. Furthermore, he has an amicable relationship with the storm dragon and stated that although he respects the vampire queen, he won't hesitate to kill her.

Although he has earned his moniker of "Continent's Wrath" for his explosive personality, there is evidence that he cares for those close to him as he has allowed Dino to live in his home for free for centuries, and sent his three sons to Tempest to train as they were too weak, likely knowing that Rimuru was too soft-hearted to kill them and would take them in instead. He gave his sons instructions to pick a fight in the capital of Tempest but not to kill anyone to gauge their combat strength first, which made them bow down to Shion after she defeated them all bare handed, vowing to learn under her.

He seemed offended at the evidence of Clayman killing off his own subordinate.

Background
A long time ago, in the age of myth, an evil giant born from the earth itself began to rampage. The giant was eventually dealt with by Veldanava and was split apart into Dagruel and his two brothers, Fenn and Glassord. Dagruel and Glassord eventually reformed and abandoned the ambitions of the evil god while Fenn kept to them and was sealed as a result. Dagruel was given land by Veldanava and guarded the Heaven Tower to prevent Fenn from being unleashed back in the world. He eventually met Twilight Valentine and formed a close friendship with them, hearing Twilight often brag about their most prized masterpiece, Luminous. He was introduced to Kisara and Basara who challenged and lost to him in a fight and became his disciples. Dagruel became on bad terms with Luminous after she killed Twilight, leading to a fierce power struggle between the two that settled down when Dagruel and Kisara got married.

For a time things were peaceful, but that changed when his wife died after giving birth to his three sons Dagura, Ryura, and Debura. He was forced to seal Bisara who rampaged in anger, and spent some time grieving over his wife's death. Dagruel later met and became best friends with Dino, inviting him to live in his home. His territory was eventually caught up in a fierce battle between Veldanava's daughter and the Mediator, placing it near the verge of destruction. He expelled the energy generated from their clash to another dimension to minimize the damage and contain the aftermath; however, the remaining energy that leaked from a dimensional crack turned the land into a deadly desert, spawning a huge sandstorm that destroyed everything. To secure food, the giants sent their young men and women across the deadly desert. These circumstances led to Dagruel desiring Luminous's territory. He eventually joined the Ten Great Demon Lords, with him and Luminous having the largest factions. Dagruel and Veldora would come to spar with each, with the two enjoying their tussles and gaining the respect of each other despite no clear winner in their fights.
