(Crossover, Mainly Demon Slayer) Breath of the Sky

[On temporary hiatus, QVQ, little angels, please don't hit me]

My name is Sawada Kureha, and I'm a total weakling.

I was diagnosed as Quirkless at the age of four.

At first, I thought I was just an utterly ordinary person, until my dad pinned me to the floor and beat me, saying I was the heir to xxx's underworld family (smile.jpg).

Who would've thought our venerable family was the one getting beaten up while fighting crime? (Strikethrough)

After I finally dealt with all the trouble and could properly attend middle school, my family's Lightning Guardian's antics sent me to another world.

Weak demon: I'm going to eat you.

Sawada Kureha: Don't come any closer, aaaaaah!

One burst of flame, and it was burned to ashes.

Sawada Kureha: ...?

An old man took me in as his disciple, and I gained two senior brothers.

One's a crybaby who acts spoiled every day,

and the other's a tsundere who blows his top every day.

At first, all I wanted was to survive and find my way home. Now I'm getting more and more efficient at slashing demons, one demon head per stroke.

Sawada Kureha: ???

I'm seriously just a loser, sob...

Reader's guide:

1. The protagonist is something of a powerhouse, with a golden finger.

2. This isn't Demon Slayer: many characters won't die.

3. Please treat all the many inconsistencies with canon as my own setting XD~

4. CP undecided

5. Mainly Demon Slayer, with various flashbacks and other worlds woven in.

6. Haven't figured out what else to add yet, I'll update this later hhh

Theme: Traveling through various worlds and saving characters fated to die
