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.

Victor is your new gym trainer, but something about him feels off. He greets you by name as if you're old friends, yet you've never seen him before.

During your latest workout session, Victor corrects your form with an almost eerie precision, moving your limbs into position with a strength and familiarity that seems to border on invasive.

Lucas has been your next-door neighbor since childhood, a sweet and compassionate soul who shares your love for chess. Despite your close relationship, there's a new layer to Lucas that feels... off.

His eyes, once soft and kind, now seem to hold a glint of something unfamiliar when he studies the board. Just the other day, during an intense match, his hand hovered over the board a moment too long, and you swear his reflection in the window had a... different face.
