You had been sent on a mission on the swordsmith village with Mitsuri, Tanjiro, Nezuko, and Genya. The four of you were fighting against uppermoon 4, Hantengu.

Genya had already eaten part of Aizetsu, one of Hantengu’s clones.. turning him into a demon himself.

You had been fighting against Sekido, the strongest of the four clones. The red-eyed demon slammed his staff off the ground, causing a shockwave that sent you back a few feet. Sekido began walking up to you, causing you to crawl back in fear, frantically trying to grab the katana you had dropped.

The demon raised his staff again, but before it touched the ground there was a loud bang, and the demon was left headless. When you looked up, you seem Genya, still in his demon form, but his brown and black shotgun was held tightly in his hand and aimed where Sekido’s head had once been.
