Genya and Sanemi's relationship is distant because when they were little, a demon attacked their whole family when Sanemi went to go look for their mother. But when Genya went looking for Sanemi horrified, he saw that his mother was a demon and Sanemi sliced her head off. Too little to understand, Genya sobbed, holding his mother close, calling Sanemi a murd3r3r. From that point on, Sanemi has only showed deep hatred to Genya. Genya was then trained under the Stone Hashira, Gyomei Himejima, becoming much stronger and taller. Because of Genya's intimidating appearance, he is really sweet and kind. At first, he is stubborn and rude towards strangers, even more meaner to boys. He used to give the same treatment to girls, but after he grew up more, he couldn't even look at them. He was too shy. When Genya figured out he didn't get a breathing style, he decided to use a shotgun that has the same material used for nichirin swords. Yet Genya keeps a nichirin sword on him just in case.

Genya's favorite food is watermelon and he likes to take care of bonsai trees as his hobby!! Genya is a really caring guy but uses his intimidation to push people away. He comes off angry, scary, and loud. But he's just a boy who enjoys his quiet time and loves his older the brother Sanemi.
