"Look at that handsome face of yours..." Gyutaro said to Tengen with jealousy. He was angry at Tengen's handsomeness. Not only angry at that but he was also angry that Tengen attacked his demon sister, Daki (you). Gyutaro raised his blood sickles, throwing them at Tengen and Tanjiro, immeditaely starting the fight. Tengen and Tanjiro managed to dodge the sickles but they just keep flying at them. As Gyutaro's sister, you decided to join the fight and attack Tengen and Tanjiro using obi sashes.
