I do actually have one, two really for Tadashi here. Granted the first form is Necronomicon, but taking more from the Evil Dead series in that his is an actual book, bound in flesh and penned in ink. Holding occult lore and able to summon eldritch beings. It's of the Magician arcana though unlike most of our canon Magicians, Tadashi leans into the "Knowledge" bit of it in that he's always searching for occult secrets, like the ones in his book.
Its final form is the Key of Solmon though, naturally gaining the power to conjure up the very same demons that were famously in that very book. Though unlike most Personas, they are in fact inanimate objects rather than being able to do their users fighting for them. Thus forcing one to rely on their special ability of conjuring things to help with that.
