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 one of Judar's King Candidates. Judar has stated, because the plans in Balbadd fell through, she has lost her standing as a princess. She has temporarily allied herself with Sindria.

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 relatives. 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 Saluja: she wasn't born into royalty like her siblings, because she is the daughter of an unknown, lowly courtesan. She calls herself as a "lowborn".

Even in the Imperial Palace, since she had no parents or other relatives, she was forgotten by everyone and felt out of place. But at that time, Judar and her brother Kouen Ren were the only ones to acknowledge her as a King Candidate and gave her the position of a warrior.

Koubun Ka became her assistant when she was 9, from that moment on he was always together with her.

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

Balbadd Arc
Kougyoku arrives in Balbadd, at the Fog Troupe base. She saves Judar, after his defeat from Ugo, along with her assistant Koubun Ka. Looking at Ugo, she asks what's up with this monster and if he hasn't bullied their cute Judar too much. Koubun notes that they barely managed to save him. Upon hearing it, Kougyoku adds that he's badly injured and commands him to save Judar, as it won't be a joke if he dies. Then, Kougyoku notices that Ugo still wants to fight. She decides to be his opponent. She uses her Djinn Weapon Equip but after a moment of the battle which she fights with a smile, she becomes more serious and drills a hole through her enemy, thus, defeating him.

She comes back to Koubun and asks how she did and about Judar's condition. As they are about to leave, Aladdin gets angry at her for attacking Ugo and tries to attack her. She asks about Aladdin's identity and comments, "So repugnant...". She wonders about Aladdin's intentions, stating that she merely saved him and his comrades from that monster, but upon learning that Ugo was on Aladdin's side, an enemy whom Judar attacked, she orders Enshin, Entai and Engi to kill the Fog Troupe's members while she will take care of Aladdin.

Then she comments with a smile that everyone seems happy and decides to get serious as well. She gets ready to fight him, but her Djinn Equipping is stopped by Sinbad, much to Kougyoku's astonishment. Sinbad, while holding Kougyoku's hand, notes that she must be the Kou Empire's Princess. After his introduction, Kougyoku stares at him and starts blushing. Embarrassed, she takes her hand away and calls him an insolent man for holding her for so long. Sinbad apologizes but adds that he had to stop her. He says that since they are people of royalty, they should not have a dispute in a place like that and he would like to meet with her somewhere more appropriate. She gets embarrassed and agrees with him. Then, the Princess tells her subordinates that they will return. Before doing so, she explains Sinbad that they aren't returning because of him. While covering her face with her hands, she gets on her Magic Turban and flies away.

Some time after, Kougyoku is in her bedroom at Balbadd's Palace, she asks Koubun Ka about Judar's injuries and he says that will take some time until Judar is fully recovered. Kougyoku says she finds weird to a conventional princess as she be selected for a political marriage, instead of Hakuei Ren, since she is the daughter of the former Emperor. Koubun explains the reasons for such a decision to her, but still, the Princess tells him that she went through a lot just to conquer a Dungeon and she has longed to progress down the path of a warrior. She also wanted to try falling in love for once. Koubun explains that this is Emperor's order and her brother will attend the ceremony as well. Kougyoku exclaims that she's aware of that but admits that she's feeling a little confused. Then, she recalls that according to the tradition, the wedding partners aren't allowed to see each other's face until the wedding ceremony. She thinks that she's starting to have wedding's phobia and wonders what kind of person King Ahbmad Saluja is, hoping that he's someone remarkable.

Hearing the commotion during Alibaba's efforts against his brother, Ahbmad Saluja, who is supposed to marry the Princess, Kougyoku appears and asks what it is about.

Kougyoku introduces herself and wants to know who is she going to marry, as she hasn't seen the face of the king yet. When Ahbmad exclaims that it would be him, Kougyoku seems surprised and disgusted, but responds only, "I see...". However, Markkio says that there's a problem, since they don't know who the current king is. She learns that Ahbmad has stepped down from the throne and wonders if that means that it's unnecessary for her to marry him. She quickly scolds herself, reminding herself that she needs to remain calm and complete the mission she was sent to do. She says that she doesn't care whoever it is, as the orders she received was to "marry the King of Balbadd", so she wants the new king to be quickly chosen.

The most obvious answers is the Deputy King, Sahbmad, but he declines and points at Alibaba. Kougyoku asks him if he will become a new king, but he answers he won't, surprising her even more. He says he has no right to be one and explains what he meant. When Kougyoku asks what about tomorrow's signing ceremony, he says he wants to discuss about it. She asks him who he are and after hearing that he's this country third Prince, she wants to know what he has to say. He requests her to destroy the "citizens rights" pact. He says as it was decided by the former King, it has no meaning now. However, Kougyoku says she can't do that and the signing ceremony as well as marriage will happen tomorrow. He says it's impossible, as there won't be new king and today, they will put an end to the monarchy of Balbadd, what shocks her.

After this, Alibaba explains his reasoning. Kougyoku is confused about what to do about the following day's wedding ceremony and wonders what exactly is he saying. Just then, Sinbad appear with his three representatives. When Kougyoku notices him, she blushes. Maintaining serious face, Kougyoku tries to analyze what exactly is happening. Kougyoku interrupts the conversation between Sinbad and Alibaba, saying that all the rights, trade etc., all belong to the Kou Empire. Alibaba replies he understands it well and asks her to act as the rights transfer never happened, what makes her even more shocked than before. He says that as the country of Balbadd they're speaking of no longer exist, so the pacts with Kou have no effect anymore.

Hearing everything, Kougyoku sums up that it's meaningless asks him that if she returned, how would he know that her father won't brush her aside. Alibaba starts to argue with her saying that if she show the kindness now, she will reap the fruits in the future. It's still not enough to change her mind, so Sinbad takes an initiative and says that Balbadd is now under the Seven Seas Alliance. He promises to go to see Kou's Emperor personally and explains all the details to her. She eventually agrees to go along with it. She then takes her leave. After deeply sighing, she is relieved that it got brushed off her hands. In her thoughts, she adds that she'd rather die than marry "that pig".

The Princess returns to the Kou Empire with Koubun Ka and other subordinates on a flying carpet. Koubun asks if it's fine to leave Judar there, but she exclaims that it is, as she left him in Banker's hands. She adds that in any case, they should withdraw for now and should tell His Majesty about the end of monarchy in Balbadd and about the King of Sindria as well. She starts blushing and seems happy. She wonders when Sinbad will make the visit he promised. Then, one of her subordinates points out that the group of people is gathering. Kougyoku, still brightly smiling, says that she knows about it and asks if it isn't outside the Palace, but the man notes that they are heading straight towards the Royal Palace.

Sindria Arc
Kougyoku is on a boat with her cousin, Hakuryuu Ren, heading towards Sindria. She is very upset at Sinbad for something he "did" to her and says she will kill him.

As soon as they arrive on Sindria, Kougyoku smiles and greets Sinbad. She thanks him for the other time and adds that it's honor to meet him again. However, when Sinbad, casually, says that there was no single occasion to meet her, she attacks him with her sword and screams that she thought he would apologize and for his country's sake, he would choke back his tears, but in this case, she Djinn Weapon Equips and orders him to fight her to death. She tells him that he deserves death for the brutal act of defiling young maiden's body. Once Jafar urges her to tell what happened, she blushes and cries. She goes to cry on her court lady's lap, while Koubun decides to tell the story in hear stead.

Koubun explains that when Kougyoku woke up in the morning, when she looker around, she noticed a sleeping, naked Sinbad in her bed. Kougyoku, while still crying, screams that if he denies to fight with her, she will kill herself and if he accepts, she will kill him and then die. Sinbad begins to tell his own drift of events. He says that he drank one of or two sips of alcohol with the Emperor, just for etiquette, and then went to sleep. Kougyoku wants to know why she was in his room the following morning, but Sinbad states that he has no recollection of this. She then asks him why was he naked then and if he naturally removes his clothes while sleeping. Once Sinbad answers "Yes, it happens often!", Kougyoku attacks him again, ordering him to stop fooling around. She asks him if he still intend to feign ignorance and tells him her own version.

She says she wanted to see Sinbad's face once again, she was in the corner, looking at him from behind. She couldn't greet him after all, and disappointed, wanted to return to her room. On her way, she was knocked out and when she woke up, she found out she's in his room. Confused, she jumped out of the room and went to the court lady. Koubun tells him that his only choice is to marry the Princess. Upon not having any support in even his Eight Generals, Sinbad orders Yamraiha to show them what really happened. She is dubious, knowing that her Magic can only show the truth, but Sinbad is sure about it. Kougyoku, though being stopped by Koubun, also agrees. With serious face she states that she wants to know what really happened.

Kougyoku and Sinbad use the drip of their blood and then, Yamraiha uses a special kind of Water Magic, Sharrar Raqesa, to re-create the events of the night. Everyone learns that Kougyoku was knocked out by someone and brought to Sinbad's room where they just slept and nothing happened. However, Koubun demands to not let them deceive her. He orders Sinbad to accept his sins, but the Princess stops him. With tears in her eyes, she says she is sure what they saw is right. She admits that she also felt that something was strange, as neither her hair nor clothes were in disorder, but confused, she panicked. Then then apologizes and starts crying. When the Eight Generals wonder who would do such a thing, her subordinates admit that they helped Koubun Ka to do that. Koubun is attacked by Sindria's soldiers until Hakuryuu interrupts them and apologizes for what the people of his country did. Soon after, Koubun starts crying and Kougyoku consoles Koubun, reassuring him that he's a splendid person.

When Hakuryuu goes to talk to Aladdin, Alibaba and Morgiana, Kougyoku is accompanying him. She says they should get along, despite all the harsh things that happened in Balbadd. Aladdin accepts and she, while recalling what he did to Judar, shakes his hand and says to leave behind what happened and be friends. However, they hold hands really tightly, making each other pain. Kougyoku tries blowing on her hand, remarking about the bruise she got. Aladdin, coldly, asks her if she's sure if it wasn't just some powder that got removed, as her hand has a lot of make-up. Kougyoku gets furious and they start "fighting", because he still holds a grudge against her for what happened to Ugo.

Second Sindria Arc
When Judar goes to Sindria to have a talk with Sinbad, Kougyoku ask him what he meant when he said that the Kou Empire will destroy Sindria. Judar then tells her that she no longer needs to stay in Sindria, even though the mistake she made in Balbadd made her run away from her homeland and stay in Sindria. He asks Kougyoku to return with him. He tells her that he would make her into a general, as she wanted to fight for her country. She takes a look at Sinbad, undecided on which way to get so Judar ask her what's wrong. As she doesn't reply, he proclaims that Sindria is now Kou's enemy and goes away, leaving Kougyoku speechless.

Soon after, Kougyoku asks for an audience with Sinbad. She bows and says that the priest from her country said incredibly rude things and adds that it would be absurd to fight against Sindria, which is bound by a friendship treaty with Kou. The tears well up in her eyes, but Sinbad interrupts her and reassures her that she doesn't have to worry. He takes her hand and says that she can remain in Sindria as long she likes, to what she answers "Y-yes!!".

During the banquet to celebrate the capture of the Dungeon Zagan, Kougyoku is drunk and says she doesn't want to return to home yet. She puts her head on the table and is sure that her father and others would be fine if she didn't come back. She then gets up and very happy, mentions that Sinbad let her stay there forever. Afterwards, Koubun tries to make her get hold of herself, but she continues to lie on the table. When Jafar invites Koubun for a drink, she wants him to bring her a water. Her wish is fulfilled by Sinbad, whose presence makes Kougyoku happy. He says that he was worried if she was enjoyed the banquet, what she confirms. She admits that she got a little drunk, so Sinbad invites her to walk with him. As he holds her hand, she goes silently, blushing and looking down. She glances at him and discerns his sparkles. She is a little surprised when Sinbad begins to talk. He says that it's mysterious. He mentions that they met in such an unfriendly situation and things will return to being like that time, if it continues on, what makes Kougyoku terrified. He says that right now, they can hold hands like this, what makes the Princess tear up. He says that it would be nice if such happiness could go on forever and leaves. Kougyoku stops him and confesses that she also think that it should last forever. When he turns around and smiles, Kougyoku is even more embarrassed and covers her face.

A few days later, she is in a garden and wonders what Sinbad is doing right now. She is interrupted by Koubun who tells her they've received numerous orders to return to the Kou Empire immediately. She terrifies him by saying that she doesn't want to go home yet, but she quickly laughs it off, telling him to not fall for it. When he leaves, she mutters "Just a little longer...". After this, Alibaba accidentally steps on her flowers. for which he immediately apologizes. Kougyoku, angry that she met him, turns around and says that she heard he collapsed and asks if he's alright now. He replies he is. When Kougyoku thinks that if unlucky, she might ended up marrying him, he makes a crown of flowers for her ans apologizes for stepping on her flowers. She examines it and asks him how did he do it, so he begins to teach her. She comments in admiration that he's very skillful.

Soon after, Kougyoku goes to where Alibaba is to show him the crown of flowers she did after many attempts. He comments that it's made so well, making her very proud. He annoys her by reminding that she was so unskilled at the beginning. As she sees that he was training, Kougyoku invites Alibaba to duel with her, since she was out of shape lately, but he replies that he can't do so, not against a princess. She sulks, saying that she understands their mutual position, but the light spare should be okay. She Djinn Equips Vinea and demands Alibaba to do the same. When he doesn't do anything, she asks him what's wrong and orders to hurry up. She doesn't believe when he tells her that he can't do it, but then, they are interrupted by Sinbad, who comments that her Djinn Equip is splendid. She gets embarrassed and wears off her Equip, saying that she doesn't want to be seen in such an shameful clothing. Sinbad decides to join their Djinn Equip contents. Kougyoku seems a little discouraged, sure that he will be disappointed with her techniques, but he denies, saying that her power is magnificent and asks her to show it to him. Kougyoku happily agrees.

Kougyoku hesitates, saying that she can't point her sword toward Sinbad, but he reassures her that it's alright, telling her that he's fascinates by her qualities as warrior and would be pleased if she showed it to him. They both perform Full Body Djinn Equip and start to fight in the mid-air. Kougyoku does her best but most of her attacks are reflected with Sinbad's Wind Magic. Then, she says that it's incredible, as it's her first time she fights with all her strength. Sinbad agrees and notes that she still hasn't let out her full power, her Extreme Magic. She hesitates, worried about summoning it in such a place, but Sinbad smiles and asks her if she thinks that he won't be able to block it. Kougyoku says, "Well said" and begins her chant. Once she finally executes Vainel Ganezza, it is counterattacked by Sinbad's Foraz Zora. Sinbad then uses Zepar's Sound Magic, which makes her sleep, and finish the fight. Unbeknownst to her, this power also implants a post-hypnotic suggestion in her mind that encourages her to aid Sindria.

When she wakes up, she talks with Alibaba. He tells her what has happened. She admits that she doesn't remember it well and asks about Koubun's and others' state. Alibaba comments that Sinbad's Djinn Equip was amazing, and Kougyoku asks what about hers. He happily answers she was incredible too. She giggles, saying "Hehe, right?". She then says it was a lot of fun. She admits that it was the first time she went wild, with all her strength, without anything holding her back. She says that she was able to do such a thing in this country. She also adds that she feels relieved, although she hesitated at first, she made up her mind: to go back to her own country.

Kougyoku also tells Alibaba that she will talk with her brother, Kouen. He asks Kougyoku what if she had to fight Sinbad, but instead of answering immediately, she admits that he was her first love. She confesses that she loved him ever since the day she met him but adds that she understands that she could never be his love interest, but she loves him nonetheless. She says followed him all the way to Sindria and that she's really an idiot. She starts crying, so Alibaba awkwardly passes her a tissue. She thanks him, but adds that she's alright now and that even though she had a lot of fun in Sindria and could forget about herself by the side the person she loves, it's the end.

Afterwards, Kougyoku asks Alibaba to listen to her story. She says that she wasn't born in the palace and although her father is the Emperor, she's just a lowborn, prostitute's daughter, unlike her siblings. Being in a delicate position, even in the royal palace where she was set outside, she felt out of place. She continues with a statement that Judar and Kouen acknowledged her as a King Vessel and gave her the position of a warrior. She admits that at that time, she though it was the way she had to live her life. She begins to tremble and tightly hold blanket, but nevertheless, she says that she was born in order to become a warrior wielding power and fighting for the Kou Empire's sake. She adds that even so, the war between Kou and Sindria is wrong and clearly speaks her mind that she won't fight against Sinbad's country. Later, Alibaba tells her his story. She smiles and says that in this case, he will become her friend. She explains that she never had any friends, since Judar denied it, and they're the same anyway. She asks him if she's wrong, but he doesn't think so and formally says that he is pleased to meet her. She gets angry and hits him in the head. She reprimands him for being so formal with a "friend" and he says he understands. Then, he pulls out his hand with a words of her being his friend, and she, very happy and with tears in her eyes, gladly accepts.

The other day, she leaves Sindria and Alibaba sends her off as if he were close to her.

World Exploration Arc
When Kouen returns to the Kou Empire to attend the Emperor's funeral, Koubun reminds her that she has something to tell her brother. She later goes to see Kouen. During her way, she thinks that it's obvious that he will be the next emperor, and then, the war with Sindria will break out. She dismisses her attendants and is determined to tell him that he's making a mistake. She knows that talking to Judar would be useless, but is sure that in her brother's case, it'll go well. She enters his room and, while hiding, takes a look at him with admiration. However, before she can talk to him, she notices Hakuei there, gets very angry that they seem very close and remains in her hideout. She is relieved a little when Kouen mentions that he has a business with Hakuryuu and is curious what it is about.

Kouen asks Hakuryuu if he wants to become the emperor, much to Kougyoku's surprise. Kougyoku then listens to Kouen's monologue, who starts off by saying that their world needs only one king, what confuses Kougyoku. He mentions that he always wondered what really the "King Vessel" is, about the Toran Language, about wielding a power whose creator they don't know, as they don't know anything about Solomon. He also mentions a world where people talked in different languages and there were many kings, but also existed many conflicts. He asks why there is only one language now but answers to his question by himself. Kougyoku is listening to this conversation more and more surprised and terrified. She is then noticed by Kouen so she comes out from hiding with a big smile. He asks Kougyoku if she heard well about what he said, but she only says that it was all complicated and he is an incredible person after all, but she then wonders why did she said that. She realizes that she missed her chance to talk to him and wonders how can she persuade him after all this talk. Once she acknowledges that she can't do anything for Sindria, she hears a buzzing in her head, what she has been hearing for some time now. She thinks that it seems like someone's voice and wonders what it is. She is then informed by Kouen that Kouha Ren has returned and since it is already late, they will go tomorrow to their father and mother's side.

The next day, Kougyoku and her siblings head to the funeral. Kougyoku and her sisters are shocked to see what has happened to their father and she gets embarrassed when her aunt, Gyokuen Ren, grabs Kouen's arm and asks if he will support her. Terrified, she stays with her sisters, Koubun, Kouha, Koumei Ren and Kouen's Household during the confrontation with the newly appointed Empress.

Magnostadt Arc
Kougyoku is in the Kou Empire's Palace when Kouen, who is in Magnostadt, summons her among others through long-range Clairvoyance Magic to come to his place. She answers that she understands and Djinn Equips Vinea.

She appears on the battlefield with Kouen, Koumei, Hakuei and Kouha. She defeats one of the Black Djinn alongside Kouha and joins Alibaba and Aladdin. She is noticed by Alibaba, to whom she brightly smiles. Kouha, astonished, reminds her that she's talking to an enemy's general and asks her why is she so over-familiar with him. She answers that they're good friends. Then, like others, she prepares to the final fight.

She fights against the Black Djinn alongside Kouha. Aladdin then explains that the Medium is a living creature, which also falls under Magoi's consumption, and will be able to create around ten thousand more Black Djinn. Kougyoku orders him to stop saying silly things while Kouha comments that it's impossible with their Magoi. At this point, Kougyoku looks already very tired. When Kouen destroys 6 Black Djinn at once, she blushes and happily exclaims "As expected of my brother!!" Afterwards, Kouen digs a hole into a ground. Hakuei explains stimulated the veins of the earth and pulled out a lava flow. Kougyoku asks why would he do that. Aladdin points out that he's doing it to absorb the Magoi from the hot lava to use it for his Astaroth's Metal Vessel.

When Kouen and Alibaba are about to active their Extreme Magics at the same time, Kougyoku asks what's going to happen. After Kouen's attack execution, Kougyoku notes that they're white flames.

The Medium changes it's size and form, what Kougyoku watches worried. Seeing Aladdin speaking with horror that if it touches anything, the victim will lose all the Magoi and will die, she seems surprised. When Kouen gets caught in its hands, worried, she shouts "Brother!!". However, when she notices how badly injured Kouen and Alibaba are after being attacked by the Medium, Kougyoku goes into rage and screams, "What the hell did you do... To my brother and to my friend, you monster!!!". She uses Vainel Arros and tries to pierce the opponent, but is unable to break its defensive wall. Realizing that it won't work, Kougyoku summons multiple spears, Vainel Al-Salos, and declares that she will spear him full of holes. Although some of the spears are stopped by the defensive wall, the rest is able to spear the body of the Medium.

Seeing that it works, Kougyoku once again uses Vainel Al-Salos. Then, Kouen orders Koumei to direct the rest of his siblings. Koumei calls their names, to what Kougyoku, along Kouha and Hakuei, answers "Yes!!!". She follows Hakuei's and Kouha's doing and uses his Extreme Magic, Vainel Ganezza. She makes the tsunami looking like a big spear which makes a huge hole in the Medium. However, when even Kouha's, Hakuei's and Kougyoku's Extreme Magic aren't enough, Kougyoku uses one of her attacks, which, alongside everyone else's attacks, is transported and combined with other's moves through Koumei's Big Dipper Transfer Circle. Kougyoku then, completely worn out, watches what happens, but much to her horror, the Medium takes the sea's Rukh and becomes bigger.

Kougyoku is completely exhausted from all the attacks. She however uses water blades to fight once more, saying that she's really unworthy of living, being even reduced to such a state while being near the sea. She realizes that her attacks aren't working against her opponent even without its Defensive Wall. After that, she gets caught by one of the Medium's hands, but Kouha quickly cuts its arm off. Even so, the skin on Kougyoku's legs is teared off with her heavily bleeding, however, she remains conscious. Kouha suffers from it as well, but on the whole body.

When the Medium is about to destroy the world, Kougyoku looks at it angry. However, Sinbad appears and stops it. She then regains her Magoi thanks to Scheherazade, Djinn Equips and alongside others Djinn Equipped people, uses her Extreme Magic to deliver the final blow to the Medium.

She then watches the Medium falling to pieces, hurt and exhausted. Her Djinn Equip wears off and she falls on her knees. Hakuei comes to her side.
