Death and Rebirth

I, Kayla, am a regular human girl. Or at least I was. This is how I went from a regular human to an immortal monster who ruins the lives of everyone I meet.

On the day I died, I was casually strolling through town when I accidentally wandered into a gunfight and got shot. I can say one thing. There is no afterlife. I was completely dead for who knows how long when I saw some huge being appear. The guy glowed. "Hello. I am Cento, the god of reincarnation."

"Cool." I had said sarcastically. "So am I like given another chance at life?"

"Yes." He smiled. "I am giving you the ability to hop worlds. You are also immortal."

"Interesting. Now what?" At that point, I realized it was a lot like some of the stories I've read, where the protagonist does and is reborn in a new world.

"Imagine a world you wish to go to and you will be there."

"Thanks." I imagined the first world. I had appeared wearing a UA High school uniform in front of the gates of UA. "This'll be fun." I gave a feral grin and walked in. Now, I'm standing in the front office. "Frost." I say to the lady at the desk.

"Go to 1A." She says not even looking up. I grin again and head there. How perfect.

"You're late Ms. Frost." The teacher says.

"Whatever." If I'm correct, this is the first day. The only problem I have is I don't know what, if any, Quirk I have. I'll just have to see.

'You've got an elemental Quirk.' The voice of the god says in my mind.

"Heh. This'll be fun." I murmur. We head outside for the Quirk Apprehension thing that Eraserhead was having us do.

"Frost. You placed first in the entrance exam. What was your farthest softball throw in Junior High?" I decided to give the truth.

"100 meters." I hear muttered wows from behind me.

"Try with your Quirk." He tosses one at me.

"Gladly." I charge up my palm with fire and a lot of wind. I managed to make it go all the way to space, as seen by the little tracker he held saying infinity. The class was all shocked but I just smirked.

"Now, we will be doing an endurance test but you will be able to use your quirks."

"Great." I grin and go back to the class.

"This is gonna be fun!" Some random girl, maybe Mina, says.

"Fun? The person in last place is expelled." Eraserhead said rather calmly.

"What!" Someone shouts.

"Let's do this!" I grin.

We did the 50 Meter Dash and I got First place there easily at 1 second. Then came Grip Strength and I got 450 KG. Not the best but fine enough. Then the Standing Long Jump, I may have done a bit much but it happens. I was first in that too. Then the Repeated Side Steps, where I simply used my wind and ice to bounce me from side to side. That one I tied with Mineta. I got first in Sit-ups, Seated Toe Touch and the Distance running. Overall I was first like I thought I'd be. I heard a couple murmurs of surprise and I just smirked. I'm going to screw everything up.

The next day, there was battle training with All Might and I was an extra point person. I'd win if no one manages to touch me so I simply sat in the room that Bakugo and Midoriya have their battle in. When they come in, they were completely surrounded by fire. I won that one and no one actually wins by getting the "bomb." Instead I sat on top of it, surrounding the "bomb."

"What exactly were you doing?" All Might questions me when we were alone after the battles.

"Playing my part. I wasn't Hero nor Villain. Nor was I a civilian. So what's that leave? Vigilante. Now go away Toshinori. I'm meditating."

"How do you- Never mind." He walks away with a sigh.

"I know your secret." I call to his retreating figure and grin seeing him freeze. Once he leaves I decide to screw with my classmates. Once I scare everyone I decide to screw up the entire plot by going to kill Shigaraki. Once I kill him and Kurogiri, I talk with All for One. "Hello Shigaraki. I am Kayla Frost. Might I meet you?"

"Kayla Frost? Hmm... What did you do to Tomura?"

"I killed him."

"Good for you. I suppose this'll be fine. All else fails, If you've got a cool Quirk I'll take it."

We meet up and I immediately stab him in the chest with my dagger. He dies and I've successfully screwed up the plot. I leave the world feeling happy.
