[Demon Slayer] I'm a Healer, Dancing on a Grave

Me: Healing Breathing. [Sobbing]

My family expected me to become a powerful member of the Demon Slayer Corps, slay demons, and bring honor to the clan... I trained hard for a year and finally mastered:

Healing Breathing.

I'm sorry, Mom, Dad, Grandma, Grandpa, and all my nieces and nephews on my great-aunt's side. I've let you down, sob, but I still have to join the Demon Slayer Corps. Even though I'm just a tiny bit off track from my dream and can't slay demons, I can help other people slay them, boohoo.

I can't attack with a Breathing Style, but I can use ordinary techniques to cut ordinary demons, though. QAQ. [One day, the protagonist splits open a stone one meter in diameter using brute force.]

With a crack, the sword breaks.

[The swordsmith responsible for making his Nichirin Blade chases him from one end of the village to the other.]

I, Tachibana Aki, die on the spot.

[Depressed] I'm so weak, I'm so useless. Why can't I learn a Breathing Style? I can only freeload at home every day. I wish I had a cute little darling to support me, boohoo.

Friendly reminders:

1. The CP is undecided, so be careful before placing your bets. Original male protagonist.

2. There will be OOC, and the writing is below average.

3. Most of it is silly comedy.

4. Original worldbuilding throughout.

5. Updates whenever. Currently obsessed with Demon Slayer.

Theme: Prosperity, democracy, civility, harmony, freedom, equality, and justice.
