Demon Slayer: Opposites Attract

When Bai Muzi first watched the anime, Lei caught her eye. She saw his pathological devotion to family.

Her heart pounded rapidly and forcefully, as if she were anticipating something.

She wanted to hear him call her “big sister,” and she wanted to be Lei’s only big sister.

One night, she finally got the chance to make that wish come true.

[Host detected. Host’s wish: Travel to the Demon Slayer world. Wish confirmed. Departing now...]

Lei, this time I’ll make sure you win.

(The heroine sides with the demons. Slice-of-life in the early chapters, then a big showdown later.)

OOC warning: I wrote this as a self-indulgent story for Lei, but Muzan really impressed me too, so my favoritism toward him should show in the writing.

This story ends at Mount Natagumo. I’ll start a second book to continue it when I find inspiration. The story is not over yet.
