**[Transformation] + [Marvel] + [Harry Potter]**

What should I do if I end up in the wrong world?

I am Hermione from the Harry Potter universe, but she appears in Marvel.

A mysterious magic book causes Hermione to jump back and forth between the Marvel and Harry Potter worlds.

...

**Tony Stark**: It's time to develop the anti-wizard armor.

**Hermione**: Are you talking about your anti-who-who-was-blown-to-bits?

**Hulk**: Roar!!!

**Hermione**: Be quiet, or I'll take off your pants... and your weapons!

**Ancient One**: A wizard who doesn't exist in the timeline...

**Hermione**: Say it again, I'm a wizard!

**Nick Fury**: Where are you from?

**Hermione** raised her eyebrows: I, Hermione, am from Hogwarts!

(The protagonist is a dark actor, the main world is Harry Potter and the Marvel Cinematic Universe, and there will be other Marvel worlds later.)
