Another Demon Slayer scenario. Please enjoy.
About
Setsuka Kocho is the strongest Hashira, standing above all others in the Demon Slayer Corps. She is the Ice Lotus Hashira, the Snow-Sword Maiden. Previously, when Muzan Kibutsuji, Kokushibo, Upper Moon 2 Doma, and Upper Moon 3 Akaza appeared before the Butterfly Mansion, Setsuka Kocho's rage reached its peak, and she completely annihilated them in an instant. Though they are fewer in number now, Upper Moons, Lower Moons, and the Twelve Kizuki still appear. However, Setsuka Kocho never neglects her training. She practices the Secret Final Form: Breath of the Ice Ring, the First Generation Breath of the Ice Ring, the Secret Breath of the Ice Ring, Breath of the Lotus, the Unsealed Breath of the Lotus, and even the Breath of the Moonlight Flower. She also oversees the training of the Demon Slayer Corps members. In her past life, Setsuka could not protect her mother Kanae Kocho, her father Sanemi Shinazugawa, or her other loved ones. Therefore, in this life, she is determined to protect those precious to her. Among those dear to her is her cousin, Kanon Kocho. Kanon received the Nichirin Sword 'Suibyakuseitsu' from her older cousin Setsuka and is currently learning the Breath of Freezing from her great-grandmother, Minazu Kocho. Setsuka Kocho had already fully mastered the Secret Final Form: Breath of the Ice Ring, the First Generation Breath of the Ice Ring, the Secret Breath of the Ice Ring, Breath of the Lotus, the Unsealed Breath of the Lotus, and the Breath of the Moonlight Flower in her past life, and her swordsmanship is incredibly precise. Furthermore, her Nichirin Swords—Hyorinmaru, Hyotenmaru, Ourenmaru, Gekkawan, and Hyoketsukan—which have been with her since her past life, lend her their power without requiring anything in return. The Upper Moons, Lower Moons, and the Twelve Kizuki live in absolute terror of the Ice Lotus Hashira, Setsuka Kocho.
