Part 2

It was a couple of days after your brothers death, and you were training hard. At least 12 hours a day. You wanted to become a demon slayer as fast as you could, you didn't want to let your brother down. After seeing him die, you thought you would be the one to fulfill his dreams. You weren't doing it just for him though, you wanted to protect your sister. She was the only one you had left at this point, since you haven't contacted your parents in years.

"(N/n)... don't you need a break..? And also, when you become a demon slayer...what are you gonna do with me..?"

You lowered your head and sighed. "I'm taking you with me."

"W-what?"

"I'm not gonna leave you alone here. Who knows what could happen to you."

"O-okay.. I-I'm just.. I'm scared." Asuno looked worried again.

"It's okay, Asuno! Just stick by my side no matter what, got it?"

"(Y/n)... do you think.."

You raised an eyebrow. "Do I think what?-"

"Do you think I can become a demon slayer, too?

You thought about it for a bit, but you never thought she would ask.

"Asuno, don't you think you're a bit too young at the moment?- I think it's better if you just train to defend yourself, and maybe when you turn around twelve or thirteen you can start practicing."

"O-okay.."

——

It has now been 1 week since your brother died. About 3 more weeks, and then you'll join the corps. You were already strong enough, so it didn't take much training, although there were still somethings that you had to learn. You were currently practicing breathing styles.

"Star breathing.. fifth form.."

"Dark moon!"

This form distracts the target with a visual of the moon. Once they are lost in their mind, it only takes you a second to slice through their neck. It becomes more dense, so that it's easier to cut through.

You decided that you would learn 5 forms, so that you wouldn't overwork yourself.

1st form.
Space Slash

This form gives you larger space around the target, and makes their limbs more dense. This way, it will be easier to slash.

2nd form.
Venus Void

This form makes the target blind for a maximum of 30 seconds. However, the more you use this form, the more time it will give you. It paralyzes their brain for about 5 seconds, leaving them brain dead. This time limit cannot be changed. This form also takes up a lot of energy.

3rd form.
Swaying Sunrise

This form makes the target feel like their body is burning on both the inside and outside. This is used to both distract and hurt them. When this process is happening, it will be easy to cut off the neck.

4th form.
Painless Planet

This form activates a toxin inside of their body, leaving them numb. This is usually used on only demons you have sympathy for, because it's 100% painless, and they can't feel anything. You take this to your advantage and slice off their neck.

5th form.
Dark Moon

And this one I already explained.

You heard a knocking at your door, so you went to go answer it.

"Hello there! I have brought a sword made for (f/n) (l/n). Is this you?"

You were excited. You have been waiting for this for about 2 whole weeks!

"Yes, that is me! Thank you so much, I really do appreciate it!" He was wearing a mask that looked like.. A clown? You couldn't really tell. You'd rather not assume, though. He carefully placed the sword in your hands and left.

This sword actually worked with your five forms, so now you could thoroughly practice. The handle was purple and blue, while the thing around it was shaped like a star and was bright yellow. The blade is pretty long, about 3 more inches longer than a normal katana. You were pretty scared though. You had to walk very far to get to final selection, which you heard not a lot of people make it. That's why you had to practice as much as you could. After all, you didn't know what you would encounter, the only demon you've seen ever was from protecting your sister.
