Now enrolled at Eisen High School, the first-year has his sights set on becoming the best Perception Artist. Kazuya has a reason besides ambition to attend this prestigious institution, as he hopes to make amends with his estranged childhood friend, third-year student Kyou Takise.

As luck would have it, the two are partnered for the exclusive Staircaser competition, in which the winners will represent Eisen for the year. In order to stand a chance against their competitors, Kazuya and Kyou will have to learn to set aside their differences first.
