The Day One Edition includes 4 exclusive, limited run only original pins in a display box, featuring Emilia, Subaru, Rem, and a brand-new character Melty! These are exclusive to physical copies of the game and will not be reprinted, so preorder today!
Rem and ram are the blue and pink haired characters in maid costumes.
It's a story/mystery based game. You'll play as Subaru I'm guessing and have to make choices throughout the story to figure out who the imposter might be. Going by the description it also seems like you'll have to avoid assassination attempts and such on Emilia, the candidate that Subaru is with and backs. If you've ever heard of games like CollarXMalice, then it's a game along those lines.
