OK I know this is the same chapter but that's because I made a mistake and the later one of my chapters was posted and I hadn't noticed because i was busy with my other stories.
So you have to go back to the previous chapter to get the full story.

The class gawped at her. Nabila was dressed in black jeans and a purple top. Clipped to her belt was a coiled barbed whip (obviously LiSer) which her hand rested against. She frowned, "What's wrong I did knock?" Oniweta sighed shaking his head Taiwabo face palmed and groaned out loud, "You're not supposed to break down the door though".

Nabila stared at everyone her face unreadable. Then she shrugged "Oops, oh well". She scanned the room, "Shall I sit here?" she asked pointing to a seat she asked pointing to a seat.

Right next to Rin's seat.

"Ahh no" Yukio said, "why don't you sit over there?" Nabila shrugged "M'OK". She sauntered over to her seat nodding at her supervisors on her way there. She pulled her seat and leaned back into it.
"Ok class we will revise over the strengths and weaknesses of water demons" Yukio called, trying to regain the Exwires attention. All eyes however were not on the teacher but on Nabila.

~Nabila's POV~ (I know total change of writing style but this section is best written in the 1st person)

Mr Exorcist still hadn't gone away so I electrocuted him. He left me alone after that.
I slept for a bit longer then got up, to be perfectly honest, I was already more or less awake just pride and stubbornness forbid me from getting up at Mr Exorcist's command. I washed my face, brushed my teeth and dressed in the first pair of clothes I had grabbed. Then I took Lisa and spent 10minutes deciding over what form she should be in.

A dagger or sword was too clunky and I wanted something easy to carry around. But I didn't want it too small I did want it to be noticed. So a barbed whip seemed like the perfect choice. I dug the Cram School key out of the pockets of the trousers I wore yesterday and turned them into my bedroom lock. I was about to smash the door open when I remembered Assiah manners and knocked first. Then I smashed the door open. Stepping over the debris I looked at the classroom, in horror.

'No, it wasn't possible. It was impossible, it wasn't them. They could not them.' I stared in horror at the people in front of me.

Then I saw Taiwabo and Mr Exorcist and I mentally shook myself out of terrified stupor. I covered my shock with an exaggerated yawn and said, "Hello I'm Nabila, the Half-Lightning Demoness, where should I sit?"

The class stared at me in shock. 'Why are they staring at me like that, they don't me, they are not them.' I frowned nervous and attempted a lame joke "What's wrong, I did knock" Taiwabo answered. "You're not supposed to break down the door though" Nothing.
"Oops oh well" I was eager to be off the front stage so "Shall I sit there?" I pointed to a seat.
"Ah no" said the boy at the front (who I was certain was the Son of Satan's younger twin brother, the one who didn't inherit the flames) "why don't you sit over there?" He gestured at a seat which I noticed was the furthest free seat away from the one I suggested. "M'OK" I agreed slightly put off. Walking over to my seat I nodded at Taiwabo and Mr Exorcist glad they were there.
I flopped back into my seat.

See the difference from between the calm, badass, Half Lightning Demoness and the sweating bullets nervous Nabila. However realise that it's because of the people in the class that Nabila is nervous or else she would be calm, badass Half Lightning Demoness and no other side to the event.

But just what is it about the Exwires that has Nabila so frightened, what's all this about they are not them.

You'll just have to Wait and See.
