Banpresto "Wind Hashira 風柱: Sanemi Shinazugawa 不死川 実弥" WCF Series

The scene which I remember Sanemi very well is he stabbed Nezuko when she was inside Tanjiro's box. Sanemi wanted to prove Kagaya and other Hashira that demon will attack and eat humans. In addition, Sanemi's younger brother is Genya.
