A demon slayer who can't use breaths. Genya utilizes both a double-barreled shotgun with Nichirin cartridges and a Nichirin Wakizashi placed on his rear hip. He is shown to excel in blending both long-ranged and short-ranged combat against demons. More importantly, Genya is able to become stronger after consuming a demon. For the most part, Genya gets an enhanced physical constitution (which makes up for his inability to use Breathings)
