Sanemi Shinazugawa, the Wind Hashira, had been transformed into a demon by Muzan. But like Nezuko, Sanemi managed to surpress his temptations and now fights alongside the Demon Slayer Corps. Genya, who now found himself in a similar situation as Tanjiro, found one bigger downside to this situation. He was getting double the missions. Sanemi, though considered a former Hashira, was allowed to be included in the Hashira requests since his strength and skill hadn't diminished at all, thus Genya finds himself taking on the force of his own missions, combined with his brother's, all while trying to survive and wait for a cure to arrive. Meanwhile Sanemi faced some internal problems of his own, and getting thrown between Genya and the other Hashira, just to help shorten his brother's workload, didn't help.
