Kougyoku Ren

Kougyoku Ren (練紅玉, Ren Kōgyoku) is the Kou Empire's eighth Princess. Kougyoku is the owner of the Djinn, Vinea. She is a Dungeon Capturer, capturing one Dungeon, and a King Candidate.

Appearance
Kougyoku is a small young girl with pink eyes and long, dark pink hair, which is pinned up with her golden Metal Vessel. She usually wears a long, elaborate dress signifying her royalty. She carries herself demurely and often hides her face behind her sleeves when embarrassed.

Personality
Kougyoku is a very willful person. She tends to act childishly, but she can become serious if the situation calls for it. Even though she puts up such a willful front, she is actually a very lonely person and wants friends. She doesn't want to follow all of the Kou Empire's orders but is too scared to disobey.

She has always wanted to have friends and close companions, but within her family, she has felt ostracized because of her parentage and has not even had the courage to get to know Hakuei or Hakuryuu, the more approachable of her siblings. Instead, she occupied herself with becoming skilled at kemari by herself, playing make-believe by herself, doing a fashion show by herself, etc.

History
Kougyoku is Second Emperor's youngest child. She has a history like Alibaba: she wasn't born into royalty like her siblings, because her mother was a prostitute. She calls herself as a "lowborn".

Even in the Imperial Palace, she was put aside and felt out of place. But at that time, Judal and her brother Kouen Ren acknowledged her as a King Candidate and gave her the position of a warrior.

She captured the 45th Dungeon, Vinea, with the help of her assistant, Koubun Ka.

When Aladdin gets angry at her for attacking Ugo, she gets ready to fight him, but is stopped by Sinbad.

She is next seen in Balbadd's palace confronting Alibaba about the agreement between the Kou Empire and Balbadd. After the agreement was done, she returns to the Kou Empire with Ka Koubun and other subordinates on a flying carpet.

Sindria Arc
Kougyoku was on a boat with her cousin, Hakuryuu Ren, heading towards Sindria. She is very upset at Sinbad for something he "did" to her. As soon as they arrived on Sindria she claimed that he had knocked her out and had his way with her at night. Because of these accusations, which Sinbad denied adamantly, Yamuraiha uses a special kind of magic to re-create the events of the night. Everyone learns that Kougyoku was knocked out and brought to Sinbad's room where nothing happened. She is confused about who would do such a thing when her assistant, Ka Koubun, admits to doing it to try to further his own status and get her with Sinbad. Soon after, she consoles Koubun when he cries.

When Hakuryuu goes to talk to Aladdin, Alibaba and Morgiana, Kougyoku is accompanying him. She says they should get along, despite what happened in Balbadd. Aladdin accepts but soon they start "fighting", because he still holds a grudge against her for what happened to Ugo.

Zagan Arc

Judal then tells her that she no longer needs to stay in Sindria, he asks Kougyoku to return with him and he would turn she into a general. She is undecided on which way to get until Judal ask her what's wrong and suddenly goes away.

Soon after, Kougyoku asks for an audience with Sinbad to apologize for what Judal said. Sinbad tells her it's alright and that she can remain in Sindria as long she likes.

Soon after, Kougyoku goes to where Alibaba is to show him the crown of flowers she did after many attempts. As she sees that he was training, Kougyoku invites Alibaba to duel with her, but they are interrupted by Sinbad, who asks her to show him her power. They start to fight until Sinbad uses Zepar's power, which made her sleep, and finish the fight. When she wakes up, she talks with Alibaba. Kougyoku tells him she will return to the Kou Empire, she also admits she loves Sinbad, although there is no chance with him.
