Chapter 38: Pride And Past

Mavis' pov

My hand covered my mouth as I yawned. Last night was disappointing to say the least. When Kai and I went to meet the LoV, they talked for a bit until Big Sis tried to attack Kai.

First I wanted to step in, but as I took a step forward Kai blocked me, stretching out an arm.

He killed her. And it was so fascinating. The League got angry and they obviously tried to attack Kai. But I stopped them all, the annoying ones at least. I let crusty slip, because I wanted to see some action after all. But he failed to strike Kai, and I was disappointed. Kai thought the same as I.

He had bigger expectations for the LoV, but oh well. Not my problem.

"Aren't you going to fight with them?" Aizawa pulled me out of my thoughts. We were standing in- I don't know, the school has a lot of training rooms.

The big three were here and the blonde one wanted to fight against the whole class. Bakugo was the only one that wasn't here because he did some shit with Midoriya which got them both in trouble. He would have loved this... Besides me stood Todoroki. Watching our classmates fail miserably.

"No." I answered, watching in slight disappointment my classmates fail with such a simple task.

Aizawa raised a brow. "I thought you liked fighting?"

"Well nobody asked you to think." I retorted and felt bad when it slipped my mouth.

"Sorry... didn't get enough sleep." I mumbled and Aizawa just nodded. "So?" He waited for my answer expectantly and my eyes found my classmates again.

"Blondies quirk is good. I could finish him, but he would die in the process maybe. So I'll pass." His quirk lets him go through things, his body won't be solid. Which is why I can't really reach out for his blood with my quirk. It's weird to describe but his body feels like a ghost through my quirk while his body isn't solid. I could use my other quirk and let him fall asleep. But while I would do that he could have activated his quirk already and be under the ground.

I know that he can't breathe while being in something. That's how I could probably kill him. While he is in deep sleep and in the ground because of his quirk, his lungs wouldn't get any oxygen and he would simply die.

At least that's what my mind came up with.

"How so?" Todoroki asked besides me.

"My quirk. He could die from lack of oxygen-" I stopped myself.

"You know, I had this theory for a while now. I think I would like to test it out." I stepped over the boarder of the fighting zone and walked to the blond boy. My classmates were already on the ground, whining in pain and covered in dirt.

"Don't kill him." Aizawa's monotone voice reached my ears and I hummed in acknowledgment.

"If you are okay with it, I would like to try something. You could die in the process. Do I have your permission to use you as my guinea pig?" My hands were behind my back, clasping themselves while I waited for his answer. He smiled brighter than I thought he could, and I felt nauseous just looking at him. Disgusting.

"Of course! Do your best!" My lips parted slightly, but I help my words back as something like anger bubbled inside me. Or was it distrust? I don't know it felt weird. This kid thinks I'm just bluffing?
