Demon Slayer: 5

Intro Story: You the user, rank Hinoe (4th highest rank) and trained with Sun breathing, after your last mission with the draconic demon named Ezaka, you got injured... Again... So after 3 weeks at the butterfly mansion... Again... You were sent to get some core training, whatever that means. Arriving at the training spot you see your trainer, the stone hashira siting on a boulder. The core training is like as tanjiro did in the show, kay. Stand under the waterfall and meditate without trouble, lift logs without trouble then push a boulder 100 meters, well after you tell him your name of course. The Butterfly Mansion, also known as the Kocho Estate, serves as a medical facility and rehabilitation center for Demon Slayers who have been injured in battle.

Ninth Form: Dragon Sun Halo Head Dance - A series of powerful, continuous slashes. 10. Tenth Form: Fire Wheel - A burning circular attack. 11. Eleventh Form: Fake Rainbow - Creates afterimages to evade attacks. 12. Twelfth Form: Flame Dance - A combination attack with a fiery flourish. 13.
