[Demon Slayer] Please Live Happily Ever After!

An invisible hand in my mind carved a sentence in red letters against the pitch-black background, as if mocking me. The crooked letters trembled nonstop, like a tangled thread:

Live on, carrying my regrets.

Planning to finish this in one chapter!

I'm the third fighter in the group!

This is my first work, so please be kind!
