Once rejected by the art world, Perception Art has now swept the globe. The medium has developed to engage all five senses, enabling viewers to fully immerse themselves in artworks. As the son of the movement's founders, Kazuya Yamanashi has inherited the talent and creativity for Perception Art from his late parents. Now a first-year student at Eisen High School, he aims to become the top Perception Artist. Kazuya has a motive beyond ambition for attending this prestigious school: he hopes to reconcile with his estranged childhood friend, third-year student Kyou Takise. However, mending the rift between them may prove difficult, as Kyou and Kazuya are enrolled in different academic streams at the school. By chance, the two are paired for the exclusive Staircaser competition, where the winners will represent Eisen for the year. To have a chance against their rivals, Kazuya and Kyou must first learn to put aside their differences.
