Shunsui Kyōraku has always been good at hiding what he feels—but when a strange mark suddenly appears beneath his skin, that becomes much harder to do. The mark reacts whenever she is near, leaving him increasingly distracted, restless, and inexplicably drawn to her. Unable to understand what's happening, Shunsui begins avoiding her, much to the confusion of everyone around him. What he doesn't know is that the mark is the result of one of Mayuri Kurotsuchi's secret experiments. And as Shunsui's reactions grow stronger, he must uncover the truth before Mayuri's experiment reveals exactly what it was designed to awaken.
