Koumei Ren

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

Appearance
Koumei is a tall man with long deep red hair tied back into a ponytail. He wears long clothes, bracelets and a large earring in his left ear and amber eyes. He carries a fan of black feathers.

Personality
Koumei stays in the shadows planning strategies and rationally planning. He tends to lose himself in strategizing so his sleep and eating habits (and also his appearance) suffer. Also, he doesn't seem to have the thirst of blood of his brothers.

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

Koumei was able to conquer one Dungeon.

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 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 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 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.
