A sound novel that features several young people and expresses the concept of youth as a whole through their individual ways of life, "242polyrhythm".

A few months ago, a mysterious disease called "Monster" cropped up in Tokyo. Inexplicable anxiety has taken hold of people's minds, yet life goes on as before. However, in the course of one morning, two encounters take place in a remote part of Tokyo called Nishi-Nippori.

Natsume Makoto meets a boy with amnesia, while two other boys, Kamada and Shun, also come into contact. The story also revolves around several other protagonists, including "agent" Umeshita, who infiltrates a school for his investigation, and a group of photography geeks called TARS.

As the stories of these characters progress, they intertwine and create a kind of polyrhythm. What will they discover when the cycle of past and present connects?
