Setsuna once thought that her life was to move towards a predetermined future based on her father's resources, and then give her sister and brother the future they wanted. As a result, on that moonless and starless night, she lost her left eye, her younger siblings, and her wet nurse.
The person who rescued her was a girl named [Butterfly Kanae] who belonged to the non-governmental organization [Demon Slayer Corps]. After her body recovered, she became the apprentice of her predecessor Naruhashira under the recommendation of them and Lord Iwabashi. She never let go of the Nichirin Sword in her hand.
She didn't want to let anyone die in the mountains where rescue was difficult to come by.
"Don't be afraid, the stars will always take you home."
