I had a sudden thought after watching Demon Slayer: Kimetsu no Yaiba, and there are many regrets in it. I won't say more to avoid spoilers. I hope you all like it. I opened a new pit. The reason for the old pit is that I am temporarily brainless and can't think of a new plot, so I'm sorry. Please wait a moment_(:з∠)_
Intention: Happiness is all that matters
