Monochrome Factor

Synopsis

The plot centers on Akira Nikaido, an ordinary high-school slacker whose everyday routine is interrupted by the sudden appearance of a mysterious man named Shirogane, who claims the two share a destiny. Akira is taken aback and dismisses the notion entirely. Later that night, his friend Aya realizes she left something at school and asks Akira to accompany her to retrieve it. He agrees, but once there, he is attacked by a shadow monster. Shirogane then persuades Akira that the harmony between the human realm and the shadow world has been thrown out of balance, and that Akira must transform into a "shin"—a being of the shadow world—to help set things right. Notably, the anime incorporates shonen-ai themes that are entirely absent from the manga.
