Dagruel

Dagruel is one of the Demon Lords in the Octagram (the council of eight ruling Demon Lords) in the anime That Time I Got Reincarnated as a Slime. He is the leader of the Giant race and holds the fourth seat among them.

He rules over the barren wastelands (often called the Barren Lands or Holy Void of Damargania) in the westernmost part of the central continent.

In the anime (primarily appearing as a supporting character starting in Season 2 Part 2 and continuing into Season 3), Dagruel is portrayed as an imposing, calm, and surprisingly wise figure despite his tremendous power and intimidating presence. He is known for his immense physical strength and is considered one of the physically strongest Demon Lords, capable of matching powerhouses like Veldora in battles. He has a deep respect for true strength and doesn't act aggressively without reason.

He has three sons (Dagura, Ryura, and Debura) who cause trouble and later get sent to Tempest for training under Rimuru.

Overall, he's a neutral-to-respectful ally-type Demon Lord in the series' events, not a direct antagonist.
