Koumei Ren

Koumei Ren (練 紅明, Ren Kōmei) is the Kou Empire's second Imperial Prince. He is a General of the Kou Empire's Western Subjugation Army together with his brothers, Kouen Ren and Kouha Ren. Koumei is the owner of the Djinn Dantalion. He is a Dungeon Capturer, capturing one Dungeon, and one of Judar's King Vessels.

Appearance
Koumei is a thin man with long, messy red hair tied back into a ponytail, pink eyes and freckles. He wears baggy robes bearing a taijitu symbol and the big dipper constellation, matching bracelets and a large earring in his left ear. He carries a fan of black feathers, which is also his Metal Vessel.

Kouha claims that Koumei is "ugly", but this might be because he doesn't take care of himself.

Personality
Koumei chooses to stay in the shadows, planning military strategies. He tends to lose himself in his work so that his sleeping and eating habits (and also his appearance) suffer as a result. Unlike Kouen, he speaks courteously to everyone. Although outwardly Koumei appears unassuming and somewhat lazy, and doesn't seem to share his brothers' blood lust, he is prepared to stop at nothing to unify the world beneath the Kou Empire.

History
Koumei is the Second Emperor's second son; he and his brother Kouen have the same mother.

Koumei conquered the 71st Dungeon, Dantalion, when he was 20 years old.

It was Koumei who devised the system of government whereby lands conquered by the Kou Empire are forced to adhere to their customs and absorbed.

Second Sindria Arc
When Judar arrives in Balbadd, he greets Koumei, who says he was worried since they couldn't get in contact with him. Judar, to apologize for his lateness, gives him a gift from Sindria. Koumei is worried about the fact Judar came from such a place. Koumei, his younger brother, Kouha, and the priest go to where Kouen is. Judar says to Kouen that he has declared war to Sindria, Koumei gets angry since Judar made not only Sindria, but also the entire Seven Seas Alliance into their enemies without the Emperor permission. But Kouen starts laughing and tells everyone that for his empire that will rule the east, the day in which it will rule the world is imminent.

World Exploration Arc
Koumei is in the Imperial City, with his assistant, to attend at Emperor's funeral, and welcomes Hakuei and her troops. Koumei is amazed at how quickly she arrived, Hakuei tells him that it was thanks to the help of Hakuryuu. After that, Hakuryuu Ren arrives along with his Household Vessel, and he seems a little worried with his change. They enter to the royal palace and Kouen arrives shortly after that, then Koumei bows to him.

The next day, he attends to the funeral along with his siblings. There, Gyokuen Ren greets her children. Koumei keeps a serious expression when Gyokuen grabs Kouen's arm and asks if he will support her. Kouha starts talking to Koumei and says that Gyokuen always fawned over En, and now it seems she has finally decided to move on from him. Kouha asks him if in that case they don't need to hear the testament, but Koumei only says to Kouha mind his manners and look forward, since the priests will begin to read the Emperor's testament. He is shocked and disgusted like everyone when Gyokuen is appointed as Emperor.

At the end of the day, he talks with his brothers about Al-Thamen. Koumei says that the "Organization" have changed their modus operandi as they begin to become so visible, referring to his aunt. Kouha tells Kouen that what happened in Magnostadt wasn't what they expected. When he was negotiating with them, even though Matal Mogamett faltered when Kouha mentioned Gyokuen, the chancellor refused to collaborate. Koumei mentions that Magnostadt is just like the Kou Empire was a few years ago, with their mass-production of Magic Tools, and the sudden development and increase in their military force. He suspects that Al-Thamen is behind it. Kouen states that it is the result of their Magicians that they were able to expand their strength to that extent, and that if they would come to oppose the Kou Empire, they would be a frightening country.

Magnostadt Arc
Koumei is working in the palace when his brother, Kouen Ren, calls him and the other Kou Metal Vessel users through long-range Clairvoyance Magic to go to Magnostadt. He answers "Ok, ok, I heard you" and enters in his Dantalion Djinn Equip form.

Aladdin is in trouble because he doesn't have any staff and cannot use his Magic decently when Hakuei uses Paimon's power to catch the Black Djinn and throws them to where the Kou warriors are. Koumei, Hakuei, Kougyoku Ren and Kouha appear with Kouen in the centre and destroy them. Then, Aladdin calls Hakuei, who is surprised to see him and asks what is he doing there. Koumei asks Hakuei is she knows Aladdin, and how are they related. Hakuei, smiling, answers that Aladdin saved her life.

Koumei is fighting against the Black Djinn along with the other Dungeon Capturers. He uses Dantalion's powers, Big Dipper Transfer Circle, which consists in attacking drawing the stars. His attacks slices the Black Djinn. Koumei comments that he's so tired, as his Djinn isn't that fit for battles. Alibaba Saluja is surprised when he sees his abilities, and wonders what the hell are those strange attacks. A few after, he and the majority of the other Dungeon Capturers are tired. He watches Kouen destroying several Black Djinn, and when his brother goes out from his Astaroth Djinn Equip and Alibaba asks if he has run out of Magoi, Koumei answers that Kouen is just switching his Equip.

After regaining his power, Kouen starts destroying the Black Djinn without hesitation. Alibaba cannot believe that Kouen really wants to destroy ten thousands Black Djinn. Aladdin exclaims that doing that is too reckless, and that they have to stop him or his body will be severely damaged. Koumei replies that it's useless, as Kouen wouldn't listen to them, and adds that Kouen is the kind of person that doesn't mind hurting himself. Alibaba, with a face of comprehension and respect, begins to say that Kouen is doing this for the sake of the world. Koumei interrupts him, saying that he didn't mean that, which surprises Alibaba, who is not understanding. Koumei comments that Kouen has an excited face. When Kouen and Alibaba starts summoning their Extreme Magic at the same time, Koumei says that they have to protect them so no Black Djinn gets close to them, at which Hakuei agrees.

After Alibaba summons his Extreme Magic, Koumei asks Kouen how long should he keep transferring the potential damages away from the city, and adds that it's quite exhausting. Kouha is behind him cheering him on. He's very surprised when Kougyoku's attacks damage the doll.

Kouen orders Koumei to direct the attacks of Kouha, Kougyoku, Hakuei and Aladdin to avoid the doll of absorbing them. Thanks to Dantalion's abilities, the attacks reach and damage the doll. Then, the Dungeon Capturers attack again, with Kouen and Alibaba joining the fight. Koumei directs the attacks, but after the impact they realize that the doll begins to steal Rukh from the sea and becomes bigger.

The doll damages Kougyoku and Kouha, and Koumei uses his power to teleport an entire mountain to damage the doll -much for the priest's surprise- but the attack fails, as the doll remains unharmed.

Alibaba exclaims that they have to use their Djinn Equip to help the Seven Seas Alliance, but Koumei objects that their Magoi is already at its limit. He fully recovers his Magoi thanks to Scheherazade and summons his Extreme Magic along with all the Dungeon Capturers gathered in the battlefield. He then watches the Medium falling to pieces, hurt and exhausted. His Djinn Equip wears off and he falls on his knees.

Koumei and his family are surrounded by the Seven Seas Alliance. When Darius Leoxses suggests that they may be hiding a trump card, Koumei answers that they don't know if the Seven Seas Alliance is hiding a trump card somewhere either, and raises his fan.

Abilities
Koumei can't do anything without his Metal Vessel.

Djinn
Dantalion

Metal Vessel
His Metal Vessel is a fan with a golden handle and black feathers.


 * Big Dipper Transfer Circle
 * 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 a great amount of material like a mountain, but it is quite exhausting for him.

Djinn Equip
In his Djinn Equip form, Koumei has horns on each side of his head and his hair loose. He wears some kind of armor and has the eight pointed star symbol on the back of each hand.

Kouen Ren
Both Koumei and Kouha show great respect for Kouen, calling him "Brother and King", and they also know very well how greedy he is when it comes to knowledge.

Kouha Ren
Kouha is Koumei's simple-minded and mischievous younger half-brother. Though Kouha teases him about his appearance, Koumei is a caring and responsible older brother. Koumei seems to worry about the well-being of Kouha, even defending him in battles, as when they fought against the Medium together. Koumei sometimes saves Kouha from the naive things he does. There are also many occasions where they have worked together and, despite having different birth mothers, their relationship is pretty good.

Judar
Despite Judar being the Kou Empire’s high priest and reliable backbone, Koumei has little patience for his eccentric antics, chastising him for disappearing without notice and playing pranks on the imperial family. Judar tends to breed worry on Koumei about his non-standard actions.

Hakuei Ren
When it appears the Medium might have crushed Hakuei, Koumei displays concern for her safety. Koumei also calls Hakuei 'Lady Hakuei'.
