Gender: Male Age: 17 (Teens) Hair Color: Black Eye Color: Grey Height: 173cm Magic: Heart Hybrid Gear Weapon: Beam Cannon Equipment Eros Kizuna has a friendly and straightforward personality. He has a very distant relationship with his mother and sister. He wants his mother to acknowledge him. Deep inside Kizuna has a inferiority complex of always being compared to his sister, because when they were kids, she was superior to him in every way possible. He always felt that his mother treated him like an unneeded child. Kizuna also doesn't like to shout out the name of his Heart Hybrid Gear. When he was a kid, he didn’t mind it at all, but right now, it is a keyword that he doesn't want to say overtly. He is also very aware of other people's feeling and doesn't want to do Heart Hybrid with them if they don't wish it. He has a very complicated feeling for his mother as he himself stated that he wants to meet her but at the same time he doesn't. Most of the boys in Ataraxia are extremely jealous of Kizuna's relationship with girls. In battle gear, he wears black outfit that emits pink light from several space. He couldn’t be called as muscular, but just from seeing one could understand that his body is fairly trained. Kizuna was the first person in the world who tested the first Heart Hybrid Gear, his mother owned a research facility (Nayuta Lab) in Ataraxia, so Kizuna was also living in this float when he was small. He was chased out from the research facility seven years ago and was forced to move into TÅ�kyÅ� float, after his mother encountered Chidorigafuchi Aine, whose aptitude for the Heart Hybrid Gear was found to be far above his. Though it was only for a short time, he lived with his big sister in an apartment in the Tokyo Float, though she eventually moved to Ataraxia and became the commander there. Kizuna was called there after Reiri and Kei discovered papers left behind by his mother detailing the method of Heart Hybrid, and its ability to solve the single largest problem of Heart Hybrid Gear pilots; their high magical power consumption and slow recovery rate. Kizuna has the power to level up a girl through perverted or lewd acts. Kizuna possesses the Heart Hybrid Gear ability, but it is not strong enough to make him particularly important (individually). Has performed climax hybrid with his sister, though she masked herself at the time, leaving him unaware of her identity. (Source: Masou Gakuen HxH Wikia)
