Koumei Ren is the Kou Empire's second Prince. He's a General of the Kou Empire's Western Subjugation Army together with his brothers, Kouen Ren and Kouha Ren. Koumei is a Dungeon Capturer, capturing one Dungeon, and one of Judar's King Candidates.

Koumei stays in the shadows planning strategies and rationally planning. He tends to lose himself in strategizing so his sleep and eating habits (and also his appearance) suffer. Also, he doesn't seem to have the thirst of blood of his brothers.
