Hakuryuu Ren Husbando

Hakuryuu Ren is the fourth prince of the Kou Empire, and later the fourth emperor following his vengeance on his mother Gyokuen Ren. He is also a Dungeon Capturer, having conquered Zagan and Belial. Initially, Hakuryuu pledged allegiance to the Seven Seas Alliance, but later defected before abdicting the throne to Gyokuen Ren, and becoming one of the world's three most wanted criminals. Hakuryuu is a young man of average height and build. He has dark blue hair and blue eyes, the left eye being a paler shade than the right. He has a large burn scar on the left side of his face and body which he received when he was a child. He also has thin, split-ended eyebrows and a mole on his chin, in the same place as his siblings and their mother, Gyokuen. He wears traditional clothes typical of the imperial royalty of Kou. He always carries a halberd, which later becomes his Metal Vessel of Zagan. Originally, Hakuryuu had real flesh limbs, but had lost his left arm to Ithnan and later both legs to Alibaba Saluja. To compensate for these losses, Hakuryuu used Zagan's power to create prosthetic wooden left arm and legs. Ultimately, Hakuryuu returned to have flesh limbs again thanks to Kouen Ren, who gave his own limbs to Hakuryuu with the power of Phenex. He has a serious personality and is concerned about small things. He also has a bit of an inferiority complex. Due to this complex, he becomes quite pessimistic whenever people surrounding him notice his weaknesses and takes such criticism personally. He greatly treasures his sister, Hakuei Ren, who has not only become a mother figure for him but is also the last of his siblings. It is revealed that he harbors an intense hatred for his mother, due to her secretly murdering half of his family. After he remembers this, Hakuryuu becomes obsessed with seeking revenge against Gyokuen for her deeds. He now mercilessly slaughters his enemies, as seen when he beheads Umm Madaura in front of her "children", and when he kills all of Hakuei's enemies on the Tenzan Plateau. He wishes to tear down the current Kou Empire and replace it with the former one, one that isn't controlled by Al-Thamen. He believes that hatred can never be erased, and the only thing you can do is erase the ones you hate. He eventually fell into depravity and sought to eliminate all that stand in his way. However, after having a talk with his defeated brother, Kouen Ren, regarding Arba's immortality and ability to change bodies, along with words from Aladdin and Morgiana, he came back from depravity after concluding that his justice (which once advocated annihilation) had changed, with Kouen's fake execution and exile being proof of that. As of the Final Arc, Hakuryuu has fully given up on revenge despite discovering Arba possessing his sister's body and charging in angrily at Arba (the latter being a ruse to get information). With revenge out of his psyche, Hakuryuu is much more sane and in control of himself.
