5 year old Y/n sat patiently waiting for the sound of the spring of trap to activate. Today was Y/n's 47th day of training, and Pyua did not make it easy whatsoever. No, in fact, the day after the poor child blacked out, Pyua only pushed her further.

Yesterday, Y/n was under a waterfall in an Iron Horse position. Were they having fun? No. Their little body started to hurt from the pressure of the flowing water.

Though it was better than the day before that, as Y/n had to learn how to leap lightly from tree to tree and ended up spraining one of their ankles. Not the funnest of days, but Y/n kept going. They wanted to be a demon slayer, and they will be a demon slayer.

Don't it twisted, though Pyua did take care of Y/n's injuries. But a part of Pyua wanted Y/n to give up on being a demon slayer. She wanted Y/n to be safe. So she put more pressure on them in hopes they would give up. But Y/n never did. They persevered and pushed their body past their limits of a normal five year old.

In fact, Y/n training style leveled that of the current hashira.

Y/n heard a spring and jumped to the tree above them, successfully landing as light as a feather. Hearing multiple other springs activate,Y/n moved forward, then to the left, back down to the ground gracefully and then rushed forward as three weapons came down from their traps and towards the resilient self.

Y/n opened their palms, hitting the sides of the blades swiftly, successfully redirecting them.

A small series of claps was heard, turning around Y/n was Pyua there with a small smile.

"Now that you have finished this task successfully, you will be starting your final trial soon."

Y/n had a sweet smile of victory on their face, the absolute relief they felt when Pyua said they were on their last trail. "Y/n a quiz!" Y/n gave a small giggle and jogged to where Pyua was walking away. "Ready!"

"What are the main keys of our techniques?"

"Stealth, Agility, Obscurity, and Painless attacks." Pyua nodded.

"What are the seven techniques of Heaven Breathing?"

"Form One: Stairs to the Gates, used for larger enemies. The attack consists of ten horizontal sword slashes that travel up the body. The last attack is against the neck, quick, powerful, yet painless.

Form Two: Feathers of the Angels, the attack comes from above. The attack consists of six sword thrusts in critical places, then the last and seventh attack is a horizontal strike to the neck, still painless. You have mentioned that this attack can become even more fatal after access to the see-through world.-"

Pyua smiled as pride swirled inside her heart.

"-Form Three: Heavenly Ascent, the attack consists of two diagonal strikes upward, one on the left side, the other the right. Once again, a horizontal strike to the neck as a final move.

Form Four: Angels Twisted Feathers, used when the user is surrounded. Twist your body while bringing your sword with you. This can either decapitate the enemy or cause a fatal wound. However, act fast to the point that it seems painless.

Form Five: Parting Clouds, the attack focuses on obscurity and only revealing yourself when it's too late for the enemy to attack. The only strike is a circle around horizontal slash.

Form Six: Chalice of Izanagi, used as an absolute peaceful ending to the enemy, one swift strike taking off the head with a diagonal strike downward.

And finally Form Seven: Retribution, the only painful attack, usually used on the Kizuki. Bring the elements stealth, obscurity, agility, flexibility and power into one and use forms one through six repeatedly."

"Good very good, but the only thing you missed was the part of your final trail. You need to enter a state of peace, so much so that not even an upper rank would notice you." Y/n only looked at Pyua nodding, they would get it done.

"What breath style does Heaven Breathing derive from?"

"Moon Breathing, with hints of Mist Breathing."

"It seems that you're all set, your next trial will begin tomorrow, then and if you complete it. You will join the final selection." Pyua opened the door for the child, her small smile never leaving her features. "Let's get you clean and ready for bed."
__________

'Maybe Pyua's crazy.'

'Just maybe.'

'Okay no definitely.'

'Crazy lady wanted me to kill a black nosed bear without it noticing me.'
___________

'Day seven and I'm surprised I'm not dead.'

The bear let out a roar as it came towards Y/n in rage. Y/n ran into the cage of the bear as it ran after them, once both of them were inside Y/n slid under the bear before it could aim a blow on them. Y/n kicked the hatch and the door of the cage slid down locking itself, the bear roared in annoyance scratching at the door.
___________

'Day twentieth.'

Y/n opened the hatch and the bear stepped out, Y/n took all the stealth and obscurity skill Pyua had taught them and put it into use as they snuck up behind the bear. Y/n accidentally made a large step but the beast did not react, it did not sense them.

'Form Five, Parting clouds.' Moving forward without hesitation and one swift sword strike, the bear's head was clean off.
