I think she means the mangas of the different episodes I've started seeing in stores, even though they're not realy mangas. Mangas have to be made in Japan, be in black-and-white, and read right to left to be classified as mangas in my book.
Yeah, they're not "real" mangas...they're essentially books with images from the tv show with captions. But manga was the closest word to what they are. They have a few out there...they're crap, so I don't recommend them unless you just want to add it to a collection.
