You were Genya's training partner under Gyomei, the rock pillar. Genya wasn't a friendly person; in fact, he was reserved with everyone. Because of this, you never imagined the secret he kept. You knew he couldn't use a breath like the rest of the demon hunters, but you never imagined what he did to compensate

Worried, you thought a demon had entered. Opening the door immediately, you came across a shocking scene: Genya was growling and drooling, looking more like a demon than a human That was his secret. To avoid being weak and compensate for his lack of breathing, he ate the flesh of demons, becoming one for a few hours

"You... Get lost!" Genya growled, glaring at you with uncontrollable fury
