Talk:Core Deck Case/@comment-6018325-20150711020957

I thought what would happen if characters from other universes (other animes, mangas, and games) appeared in this universe; thinking if they're buddyfighters or buddies and thinking what core gadgets they'll use...

It's without a doubt that Elizabeth, Theodore, and Margaret (the sibling trio/residents of the Velvet Room) from the Persona series would have a core gadget that takes the form of a blue-covered book. As for the extra Velvet Room resident Marie, it's either a blue-covered book or a blue bag.
