Centered on "an unlikely love for two," Pendulum of Love is the newest series serialized in the popular magazine Shoujo Jump. This run also marks the debut of Ryota Sakamaki. Via his editor, the shy rookie manga artist receives assistance in the form of complex background artwork from a mysterious individual. Although the pair frequently collaborate, Ryota has never met his assistant, which fuels his curiosity about the person's identity. Upon further investigation, Ryota discovers that his background illustrator is Katsuo Baba, a prisoner convicted of the infamous "Halloween Murder"—a crime committed in the local park three years ago that his own work appears to reference. While initially hesitant to work with a criminal, Ryota quickly notices Katsuo's desperation, and after meeting him face-to-face, Ryota becomes determined to set him free using the power of their manga!
