Akaza continues to offer Rengoku the chance to become a demon to improve his skills. Rengoku refuses his offer and is trying his best to keep up with him. The fire Hashira has one goal:to protect his comrades even if it costs his own life.

One day, Tanjiro returns to the Butterfly Mansion and finds Sound Hashira, Tengen Uzui, attempting to take Aoi and Naho away on a mission against their will. Tanjiro, Zenitsu and Inosuke offer to go on that mission instead, and they head to their next destination - the Entertainment District.
