[Demon Slayer: Kimetsu no Yaiba] [Hot-blooded battle] [Single heroine Butterfly Ninja] [Combat power improvement] [No system, no cheats]
When his sister signed the contract, the butterfly ninja knew that he had no way out.
She has neither talent nor wrist strength, and it is difficult for her to kill even the most ordinary ghosts on her own.
In Demon Slayer Squad, such people usually have only one ending - die in the mission, or become a drag.
But there was another person living inside her.
The figure that had appeared in her nightmares would take over her body when she was about to die, and use sword skills she had never seen before to cut off the enemy's neck. He is her trump card, her only unequal bargaining chip in this cruel world.
One body and two souls. She will use this body to embark on a path she has never walked in her previous life.
