The beloved anime "Shuya Marionette" follows the typical plot of a leading hero with a group of admirers, yet fans cannot get enough of the notorious antagonist, Slow Dening. Known as the porcine Duke, Slow was once a talented magician and the rightful heir to the Dening estate but squandered his potential. However, his underwhelming persona was a façade to appear equal to his loyal companion, Charlotte, whom he secretly loves. Unfortunately, the anime's storyline does not offer a fairytale ending for the Piggy Duke, as Charlotte eventually leaves him to join the hero's coterie.
One disappointed viewer finds himself thrust into the world of Shuya Marionette, inhabiting the despised body of Slow. However, he vows to change his revolting behavior, repair his dismal reputation at school, and alter the series' ending with Charlotte. Nonetheless, the opposition's nefarious schemes will thwart his journey to a happy conclusion.
