Kougyoku Ren

Kougyoku Ren (練紅玉, Ren Kōgyoku) is the Kou Empire's eighth Princess. Kougyoku is the owner of the Djinn, Vinea. Judal has stated because the plans in Balbadd fell through she has lost her standing as a princess. She has temporarily allied herself with Sindria. She is a Dungeon Capturer, capturing one Dungeon, and a King Candidate.

Appearance
Kougyoku is a small young girl with long, dark pink hair, which is pinned up with her 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 appears to have fallen in love with Sinbad at first sight. She becomes very nervous and embarrassed when around him. Others have commented that she would do anything he says, a fact that he himself has not seemed to notice. Kougyoku has also admired her half-brother Kouen for some time.

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 has a history like Alibaba Saluja. She wasn't born into royalty like her brothers, her mother was a prostitute and she was a "lowborn". Even in the royal 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 Dungeon of Vinea, with the help of her assistant, Ka Koubun. We also know that she's the daughter of the emperor.

Balbadd Arc
She arrives in Balbadd, at the Fog Troupe base. She saves Judal, after his defeat from Ugo, along with her assistant Ka Koubun. She gets attacked by Ugo and retaliates by using her Djinn Weapon Equip and drilling a hole through him, thus, defeating him. 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.

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 servant admits to doing it to try to further his own status and get her with Sinbad.

World Exploration Arc
When Kouen returns to the Kou Empire, she worries about Sindria and goes to talk to Kouen. Before she can talk to him, she watches as Kouen has a talk with Hakurei and Hakuryuu. She is then noticed by Kouen which she then comesout from hiding. Kouen then informs her that Kouha has returned.

The next day, Kougyoku heads to where the funeral with the her siblings. She is shocked to see what has happened to the emperor. After the funeral and the next emperor is appointed, she leaves the hall.

 * When using this Extreme Magic the Metal Vessel Symbol appears behind her while she recites the spell. While she is reciting a large amount of water gathers toward the symbol until enough water to flood a city is gathered. When she unleashes it, it takes the form of a giant tsunami.

"Spirit of sorrow and isolation… thou who controls the power to make kings, bring forth the great raging streams that judge the surfaced earth!!"
