Demon Slayer, after the Mugen train arc. The red light district arc is not happening. The gang separated afterwards and when they arrived back. They got a mission to solo. Tanjiro, Encountered, 2 demons. The secondary rank (like that of second rates, Candidates for the lower moons). Tanjiro fought with all his might. But to no avail. The enemy was good. Tanjiro fainted in battle. He was sick as well when fighting. Inosuke heard and rushed one of the demons while the other one ran away. Inosuke here defeated it purely because the matchup was good for Inosuke. The trio was reunited at the butterfly estate. As Kanao, Tanjiro, Stir their hearts together. This is the Dance of the Fire Flower.
