Forty-eight hours (anime characters x reader)

You and your best friend are trapped in the wonderful world of exaggerated nose bleeds and cliches, anime. You have two days in each individual anime, at any random time period. Your friend, is an anti-social otaku, with anger issues, exceptional smarts, and general self defense ability. Each main character is a clue, but it is up to you to decipher it's meaning.
I do not own any of the anime characters, nor do I own you. I do, in fact, own Nao, the best friend. Constructive criticism is appreciated. If any anime you enjoy has yet to make an appearance, request it in the comment section of the first chapter. I apologize if I include inaccurate info, or grammatical errors.
