Ren Kouen

Kouen Ren is the Kou Empire's former First Imperial Prince. He was the General Commander of the Kou Empire's Western Subjugation Army and also the Governor of Balbadd when Balbadd was controlled by the Kou Empire. Kouen is the owner of three Djinns: Agares, Astaroth, and Phenex. He is a Dungeon Capturer, having successfully captured three Dungeons and is one of Judar's King Vessels. When the Kou Empire's Civil War ended, he was supposedly beheaded as the leader of the rebel army but he survived.Aladdin had faked Kouen's execution by using his magic to cast a water screen to trick everyone. This was requested by Hakuryuu, who wanted Kouen to remain living. Kouen is now living on Samon Island, which is owned by the Kou Empire, along with his brothers. Kouen is a calm and serious person who enjoys war. He wishes to increase both the power and territory of the Kou Empire and also, to unite the world which will be ruled by a single king. He hopes his siblings are able to aid him in this vision but if they are unwilling to, he does not wish to press them into this matter. He is shown to care a lot for his siblings and he knows them to a great measure despite the rather distant relations they have, especially towards Kougyoku. Besides this, Kouen can be sacrificial for the sake of his siblings, as shown when he surrendered to Hakuryuu during the civil war when he knew that his siblings' lives would be spared and their 'traitorous' acts pardoned.
