Harry Potter: The Truth Is Out, I'm a Dimensional Mage!

I'm Wang Lin, a rational Sorcerer Supreme who believes anything can be exchanged for something of equal value. An accident dropped me into the Harry Potter era, and from the start I got into a fight with Dumbledore.

Then I found a clever, adorable little scammer with silver hair and blue eyes.

[To-Do List]:

Solve her magical outbursts (she's on the verge of becoming an Obscurial).

Track down the gang trying to kidnap her and put them out of their misery.

Correct her mistaken belief that “I'm a human trafficker.”

Stop her from turning Dumbledore's phoenix, Fawkes, into soup!

To get her to go to school, I had to help support an entire orphanage.

But she kept packing food into Hogwarts plates and pestering me every day to open a portal and send it back.

Emily: “Bad man! Human trafficker! Open the door, my little brothers and sisters are still hungry!”

Me, rubbing my forehead: “...Just this once.”

Later, she hugged my living cloak and whispered, “Cloak, do you think that bad man is feeling down? Should I make him something tasty?”

The cloak, turning to nod furiously at me: [She cares about you! You're in her heart!]

I looked at the girl who was usually as clever as a little fox, but would throw herself in front of me without hesitation whenever I got hurt...

Oh no. It seemed my one and only “unequal exchange” had finally come along.
