It's off to a good start so far. I like the political storyline as it's a great way to push our protagonist into the deep end.
That being said, I find the 4th wall thing a bit jarring, but at the same time, it does add flavor and style. EDIT: I also feel the 4th wall thing might work better if it's coming from the main character rather than an anonymous narrator
I also wasn't big on the Training Montage. Whilst I like the idea of parodying/tributing such montages often found in movies (especially superhero movies), but the way it's written just feels awkward.
For example:
Day 15:
Woken up with a bucket of ice cold water splashing over her face.
Hovering in the middle of the room only a few centimeters above the ground, swaying left and right awkwardly.
This reads more like notes being taken rather than a story. If you had written it more conventionally this section would have worked much better. Something along the lines of:
Abigail is awoken by a bucket of ice-cold water. She awakens from her slumber and led to the training room. Vanish watches as she attempts to use her abilities, but all she can manage to do is awkwardly hover for a few seconds.
Finally, your dialog ends by describing the exact emotion we're supposed to take out of it, even when that's unnecessary. For example:
Stood in the middle of the hall, Vanish began tossing medicine balls at Starlight, who jumped out of the way like they’re dodge balls. “You’re supposed to catch them” she was mocked.
From the context of what had happened, I understood that Vanish was mocking Starlight. It just adds unnecessary words.
Still, I can see a lot of potential in the story and hope to see more.
