Water Hashira Giyu Tomioka's Pain

When the four emotions do not disintegrate, Tanjiro informs Genya of a hidden fifth demon. Genya expresses jealousy towards him and declares he too shall defeat an Upper Rank, to which Tanjiro responds with encouragement. He and Nezuko fight off the demons while Genya finds the now minuscule Hantengu, but he fails to behead him before Sekido attacks. Believing he will die, Genya recalls his past; he and his family were frequently abused by his father, who was later killed. One night, a demon entered their house, killing all five of Genya's younger siblings before it was fought off by Sanemi. He later found him standing in front of their mother's body, who was the demon, and branded him a murderer in his grief. Genya laments dying without apologizing to Sanemi when Tanjiro saves him from Sekido. After Genya saves him from Aizetsu, Tanjiro goes after Hantengu.
