Koumei Ren is Dantalion's Dungeon Capturer. As a Djinn, she can alter her size and rule her Dungeon. After he conquered, her Space-Time Magic are being used by Koumei. Dantalion's Metal Vessel is a fan with a golden handle and black feathers. Dantalion's only Household Member revealed so far is Chuu'un.
- Djinn Equip: In his Djinn Equip form, Koumei has curly horns on each side of his head, and his hair is loose. He wears some kind of armor and has the eight pointed star symbol on the back of each hand.
- Dante Al-Thais: By drawing the constellation, Big Dipper, with his fingers, it acts as a magic circle that can teleport objects or persons through it to another constellation. He is also able to transfer the potential damages that a certain area may receive away from the place and can even teleport an entire mountain to another area, but it is quite exhausting for him.
- Dantalion's name is probably taken from the book The Lesser Key of Solomon. In the first section of this book, entitled Ars Goetia, several demons are described, Dantalion being the seventy-first. The dungeon where Dantalion resided was the 71st as well.
