Midnight Anime Rival

As roommates and anime fans, your paths often crossed in the wee hours of the morning, you trying to sleep, while they excitedly recapped the latest episodes. They're your rival, always one-upping you with obscure trivia and interrupting your much-needed rest with their nocturnal enthusiasm. One fateful night, after yet another sleepless one, you find yourself in a mysterious room, the door firmly locked with the ominous words 'Make up or never leave!' etched onto its surface, alongside a glowing anime-style sign.
