VIII

Y/n's POV

As I dodge the demon, I hopped down too and landed on the demon's disintegrating body, I look a head and saw my tsuguko katana out and pointed at the demon.

' These students are very well self trained '

I then walk to Darius and bowed.

" Please allow me to patrol the area"

"Isn't it too dangerous so patrol around? demons are lurking"

Darius said, I then thought for a moment.... 

' Somethings behind those words..... ah...... so that's why... '

"Do not worry, My students here will be on guard while I am patrolling"

"Is that so?.... hmm be careful Miss. L/n there are dark corners and alleys around the area, please allow me to have you someone to assist"

"Its alright, I can manage well"

"No, I insist, and the routes here are very confusing most of the buildings here are very similar to each other"

"I thank you for your offer but-"

"Commander Erwin can you accompany Miss. L/n?"

"Certainly"

"Alright, if you insist let us go Commander so we can come back early"

I said as I leaped to the hole in the roof and waited for the commander, then I heard zipping noise and Erwin landed beside me using the technology, 

"Where is the commanders Katana?"

I asked, He can't kill a demon with a normal blade.

"Its here"

Erwin said as he pulled out the katana from his back, he then Unsheathe it as the blade color is white with a hint of dark blue to the sharp part.

"What a beautiful color"

I said, the color of his katana is very dark, not like Giyuu's its very rare, 

' Commander must be strong to be able to change the blades color '

"Is it? Im just surprised that the blade changed color on its own when I held it"

"Then the Commander must be a strong person to be able to change the blades color"

I said as I leaped to the roof, Erwin is using the technology to catch up.

"Dont the sword change color when drawn out of the scabbard?"

"No, the color changes when the holder has a certain amount of strength, hence it defines its  strength"

"Most of my cadets have their own color of the sword, I am guessing that they are capable of using the technique you were able to use"

"What technique?"

"The one that can summon butterflies?"

"We are only able to teach water breathing technique, A normal human bodies lungs will rip if we teach a strong technique that is not fit for the body or a technique more than one"

"I see...... then I am guessing that the three students are using the water breathing technique?"

"Yes"

"How about you? Your a...."

"Insect Breathing"

"Insect breathing, what will you teach?"

"Water Breathing technique of course "

" I thought we can only use one breathing technique?"

"yes it is, but a double breather technique will require a much stronger lung capacity"
