Hi there everyone! Before I start I would like to apologize for the false notification as this is not a chapter it is just a question.
So recently I started watching Demon Slayer (Maybe better known as Kimetsu no Yaiba), anyways I have some good ideas for a semi-crossover and was wondering whether you would like this or not, just comment yes or no if you have an opinion in the comment section below!
What I'll incorporate from Demon Slayer if there are more Checks than Xs is basic breathing techniques as that is not a to AU concept that could be easily incorporated. Sorry again for the false update and I am completely happy with both outcomes of the vote. Have a good day y'all!
Edit: To clarify, there will not be any characters from Demon Slayer, and the breathing thing will not be Nen.
