Definitely more confusing. Even though she's learned a little more about modern different worlds while being here on the train, all of those words are still confusing to her. Manga, anime.. media..

At least she knows games, though she didn't know those had characters? Weren't they just about accomplishing simple goals? How could anyone write anything about that?

She looks confused as she speaks, but Alice is still trying to understand it. It's not like she's totally dumb, after all.

"So it is fiction based on.. already existing stories?"

That's the closest she can get. Which is actually what fanfiction is, good job, Alice. It's just that she's only barely grasping the concept, even as she's laying it out in words like this.

".. and it involves rat poison being ingested?"

Don't think she forgot about that part.
