Dino

Dino is a Demon Lord in the anime That Time I Got Reincarnated as a Slime, specifically the sixth seat among the Octagram (the group of eight recognized Demon Lords). He is introduced in Season 2 (Part 2) and appears more prominently in later seasons.

He is a Fallen Angel (originally one of the ancient primordial angels created to serve the world's creator), now fallen from grace and classified as a demonic being. Despite his immense power—he's considered one of the strongest swordsmen in existence with exceptional combat abilities—Dino is extremely lazy and laid-back. He has a perpetually sleepy, carefree demeanor, often avoiding work or responsibility whenever possible, earning him nicknames like the "Sleeping Ruler" or "Wandering King."

In appearance (as shown in the anime), he looks like a youthful, attractive young man (almost high-school age) with messy silver-purple hair, dull/sleepy blue-gray eyes, and a relaxed, unkempt vibe. He typically wears light, casual-yet-heroic clothing, like a shirt with pauldrons and a cloak, and carries twin swords.

His personality revolves around slacking off and conserving energy, but beneath that facade lies sharp intelligence and hidden depths of loyalty or regret in key moments. He becomes associated with Ramiris (another Demon Lord) as a sort of researcher/assistant in her labyrinth later on.
