Butterfly Soul in Another World: I Transmigrated Into a Martial Arts World

(This book includes Yiren, Busi Hua, Zhen Gu, and canon pairings. If these pairings are a trigger for you, please steer clear!)

In the original story, Hu Die Ren died at the hands of Douma. A wisp of her lingering soul wandered in the land beyond the mortal realm, unwilling to be reborn because she still clung to her unfulfilled ideals.

When she opened her eyes again, Ren found herself in an unfamiliar martial arts world.

In her new body, she was a pampered young lady with no strength to fight, but she still had all of the Demon Slayer Corps' memories and the Insect Breathing technique.

Her old comrades were scattered across different regions, some enemies and some allies. This world was no longer simply about fighting the encroachment of the demons known as Sui. It also held the greed and selfishness of human nature.

The martial world was treacherous, and the Sui ran rampant. Amid the vast crowds, she once again encountered that cool, distant figure: Tomioka Giyu.

She had owed him in her previous life, and would make it right in this one. This time, she would no longer endure and back down. She only wanted to draw closer to him, treat him well, and protect him.

What she did not know was that he had transmigrated too.

He had fallen into this world and lost all his memories of the original story.

When the martial world met blades forged from Breathing techniques, and the fate of the past returned, she rose with her blade in hand, determined to stand at his side, wipe out the shadows of Sui, and end the calamity of Muzan.

This time, I will run to you, take your hand, and return with you. We will never be parted again.

The legendary Black and White Heron Immortals: one fell into darkness, while the other ascended.

Eternal immortality, eternal slumber.
