Kougyoku Ren is one of the princesses of the Kou Empire.
Kougyoku was a daughter of the king and his concubine. Since her mother was a prostitute, she was a princess of lower status. Koubun Ka was assigned to watch the young princess and served as her guide. Unbeknownst to the princess, Koubun Ka is using her to climb his way to the top of authority in Kou Empire.
Kougyoku Ren is created by Shinobu Ohtaka who has no information regarding any inspiration used to create her. Her name, 練紅玉, in Japanese means red ruby.
She is a young, woman with red hair with a dark pink tone. Her hair is tied with her hair pin and fashioned into two loops, resembling a bunny's ear, while her pony tail reaches past her nape and shoulders. Her attire is quite similar to the Hanfu, a traditional dress for the Han people of China. Her sleeves are long enough to hide her delicate hands. Her outfit has a pink top layer for her chest over a green dress that reaches her legs. The green dress is layered and parted on top of her darker, pink dress.
In her full-body Djinn Equip form, her hair is blue while her body is covered in clue scales except for her cleavage and navel areas.
Being a Dungeon Conqueror, she has access to Djinn's powers when she obtained Vinea. She is skilled enough to do a full Djinn Equip and to use Extreme Magic spells. Her Djinn Metal is her hairpin which houses Vinea.
