Deuce Spade is your average NRC student, eager to rise the ranks and become an honor student. Unfortunately, his plans are sidelined when he falls through a broken mirror and ends up in a reality much like his own. Momentarily believing everything to be normal, he continues about his day when his world comes crashing down: He comes face to face with Heartslabyul housewarden Vil Schoenheit and Octavinelle vice housewarden Ruggie Bucchi!? Shocked to find that he is no longer in his world, Deuce must navigate through the unfamiliar life he (or a different version of him) lived while trying to find his way back home.
