Djinn: Dantalion
Koumei Ren is the Kou Empire's second Prince and a General commanding the Western Subjugation Army alongside his older brother Kouen and younger brother Kouha. He's captured a single Dungeon and counts among Judar's King Candidates.
The guy's basically a strategist through and through—he operates in the background, running calculations and plotting the next move while his brothers handle the flashier stuff. Fans often note that he can get so absorbed in planning that he neglects the basics: sleep, food, hygiene. It's kind of a running thing. Unlike Kouen and Kouha, though, he doesn't seem driven by bloodlust; he's more the calculating type than the warrior type.
