Genya Shinazugawa

Shinazugawa Genya is a Demon Hunter of the Demon Killing Corps. He is also the younger brother of the Wind Pillar Shinazugawa Sanemi.

Final Selection Arc
Genya participated in the Final Selection exam, managing to survive the seven day trial. He impatiently inquired about receiving his Nichirin Blade, angrily hitting both his Kasugaigarasu and one of the proctors when his demand went unfulfilled. He was then grabbed by Kamado Tanjirou, who promised to break his arm if he didn't immediately let go of his second victim, something Genya dared him to do. Tanjirou obliged, leaving the irate youth to nurse his broken limb, with the choice for the alloy of his future sword then presented to him.

Demon Train Arc
Later, at the Butterfly Estate under unknown circumstances, Genya intentionally tried to bump into Tanjirou, ignoring his greeting afterwards. He later received the report of Rengoku Kyoujurou's death via Kasugaigarasu, in the company of Himejima Gyoumei.
