Dagruel

Dagruel (ダグリュール) is a Demon Lord, the leader of 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
Dagruel has the appearance of a middle-aged man with blue eyes and slicked-back blue hair. He has three tattoos on his face resembling long teardrop-like lines: one at the center of his forehead, and two below his eyes running over his cheeks in the direction of his sideburns.

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

Personality
Dagruel is an observant person and is not as belligerent as his appearance would suggest. He is calm and sure of his strength, with his quiet confidence not blinding him to the subterfuge present among his fellow demon lords.

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 also constantly 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 into the world.

After he met Twilight Valentine and formed a close friendship with them, he would often listen to them brag about their most prized masterpiece, Luminous. Kisara and Basara, who were also created by Twilight, had challenged Dagruel to a fight, with the two becoming his disciples after losing to him.

Dagruel's relationship with Luminous worsened significantly after she killed Twilight, leading to a fierce power struggle between the two that only settled down for a brief period when Dagruel and Kisara got married. Dagruel had three sons with Kisara – Dagura, Ryura, and Debura – with Kisara soon passing away and throwing Basara into a rampage. Dagruel, who was still grieving over his wife's passing, sealed Basara away.

His territory was eventually caught up in a fierce battle between Milim Nava and Guy Crimson, 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. This would spark a desire in Dagruel for Luminous' territory. He later joined the Ten Great Demon Lords, with him and Luminous boasting the largest factions.

Dagruel became best friends with Dino, inviting him to live in his home. He also befriended Veldora and would come to spar with him on numerous occasions. Though no clear winner in their fights, both still gained the respect of each other.
