Y/N'S P.O.V

We arrived at Wing-san's room. I didn't mutter any word I just stood there quitly with an expressionless face. Killua keeps glancing at me but I don't give two shits, what he said earlier hella hurts my pride.

Wing-san is currently explaining about Nen "Only one thing can protect you from Nen. You must also learn Nen. You must use 'Ten' for defense. Otherwise," he put his hand on the wall and uses Nen, the wall now have big cracks.

"Your body will be crushed" I said. Wing-san look at me and said "hmm ? Yes yes, How did you know? Do you already used Nen?" He ask.

" no, I have some knowledge about Nen, but I decided to wait for this day, so that the three of us will learn Nen together" I said not looking at Gon and Killua.  I'm still pissed so yeah.'

'I feel guilty for saying that, she wanted to learn Nen with us, even if she can learn it right away whenever she wanted to. Sigh, I need to apologise I can't bare the tension on us.' Killua looks down feeling guilty on what he just said.

"I see, let's talk later Y/N-chan, for now let's continue. We need to open your aura nods." He said I just nod in reply.

Hours passed and finally! Wing-san's lecture is done! "Wews my brain can finally relax'. I decided to listen cause  there are some parts that I forgot.

"I will direct my aura towards you. This is known as Hatsu, which I demonstrate earlier. Naturally, I will restrain myself, since my objective is not to destroy your bodies. However, this is way is perilous. In other words, I will attempt to shock you into awakening. I will give your sleeping body a jolt, so you can learn 'Ten' more easily." Wing-san keeps on talking what he will do and what will happen we listen carefully and seriously.

"Now put your belongings down and take off your clothes and Y/N-chan will go first." I removed my clothes, I was only wearing some sports bra.

I walk my way towards Wing-san. Glancing at Killua he looks so red and........ Huh!? Is that blood on his nose!? Daheq happen to him?! I shrug it and continue walking.

KILLUA'S P.O.V

When Wing-san said to take off our clothes I automatically look at Y/N, she takes off her clothes my eyes widened when I saw her in... Sports bra. Looking at her body my face heated, da-damn for a 13 year old she has big size- HUH!? HEY! STOP IT! I'M NOT A PERVERT!!!' I mentally slap myself for thinking such things. 'Im still 12, what Am I doing!?'.

I felt hot liquid drop from my nose, reaching for it my eyes widened when I see .... 'BLOOD!? NOSEBLEED!?' I slightly panicked, Gon looks at me worriedly,

"E-EHHH?! KILLUA! ARE YOU OKAY WHY IS YOUR NOSE BLEEDING!?" He yelled causing Wing to looks at our direction, he chuckled looking at my state and knowing whats the cause. I felt my face heat up again. 'that was so embarrassing, thank God Y/N didn't notice me, and Gon is dense for things like this'. I thought.

Y/N'S P.O.V

"I'll begin" and with that he directed his aura towards me. Closing my eyes, I bit my lips trying to contain from shouting and pain I feel, until tasting the familiar taste of iron blood.

'Its so hot, I can feel pressure, even though Wing-san isn't touching me. You can really feel the invisible and slimy thingy crawling across my skin'  I thought.

"Every Micropyle on your body has opened."  Opening my eyes I saw and feel my aura I was about to say something when suddenly my aura went berserk the instead of white mine was blue, causing the things inside the room flying and walls began to break. 'oh shit shit shit shit how did that happen, I didn't know my aura is THIS wild! Bruh the fuck!!!! How the fuck do I stop this!' I thought panicking what might happen if this won't stop.

WING-SAN'S P.O.V

'oh god! How does this girl contain so much aura!? Did I do something wrong? No, it's her aura. I need to calm her down or this room will completely collapse and she'll be in danger!' I thought looking at the girl surrounded with blue aura instead of white.

"Y-Y/N-chan! Please calm down! Try to Control your aura! Concentrate your aura within your body! Close your eyes! She automatically follow what I said and close her eyes.

"use any stances that helps you to focus , then visualize your aura flowing like a blood through your body. From the top of your head to the your right shoulder, to your hand, before passing through your legs, to the left side. And now visualize that flow beginning to ebb and hovering around your body." I sigh in relief when I see her aura finally calm down.

Glancing at the boys they have an unreadable expression.

'Even I didn't expect her to have this much aura. That was indeed a shocking truth. This three are very incredible, I need to talk to her later. I also need to tell Netero-san about this' I thought looking at Y/N as she slowly open her eyes. Her eyes are tired, she was about to collapse when someone catched her before falling.

KILLUA'S P.O.V

I look at Y/N with visible shock expression, remembering her aura went out of control. Shivers run down my spine 'that was so cool at the same time terrifying.'

She finally open her eyes and about to fall, my body automatically run and and catch her body before she hits the ground.

Looking at her worriedly, she looks at me, ".......Kil...lua" She said weakly and then finally her eyes closed. I look at Wing-san before I could say something he beat me and said "don't worry Killua-kun, she'll be fine. She's just exhausted." I nod and sigh in relief.

" Now put her in the couch and lets continue okay? You don't have any time left" He said, I carry her bridal style and put her in the couch and then kiss her forehead.

With that we continue learning Ten one of the principles of Nen.
