Azkaban: Dark Magic Awakens

My name is Aislin. I'm an utterly ordinary player of Harry Potter: Magic Awakened, the Azkaban edition.

Except I've spent a lot of money on it.

But spending money can't change bad luck, and it can't change fate. My luck is always as terrible as ever. I wanted to summon magical creatures and have some fun, but all the cards I pulled were the kind that would send me straight to Azkaban.

I've maxed out all three Unforgivable Curses, but I can't even summon a dragon egg.

I gave up.

Then, on that very night, I transmigrated into the original story with my alt account.

I looked at the motionless model of my alt beside me, then at my main account's face in the mirror, and fell into deep thought.

The next second, my alt started moving.

I accidentally cast Avada Kedavra.

In broad daylight.

Well, good news: there weren't many people around, and only one person witnessed my crime.

Bad news: that person was Albus Dumbledore.

Damn it, I don't want to be locked up in Azkaban again! I don't want to spend another day somewhere I can't duel.

So said I, who had just been released from Azkaban in the game.

The main story is in third person. The love interest is another original character.

Theme: Turn everyone's understanding of the original story upside down.
