Later, Paff and her media company, Monophonic Entertainment, announced the date for her annual event, PAFFCON. By browsing through iM and through each character's private 'OS logs', players can unlock new songs and gain insight into the story of Cytus. A bunch of top musicians performed, but the organizer, Aesir, was nowhere to be seen, even after the end of the event. Attendees of the event included Paff (stylized as PAFF), a popular singer, Neko Asakura (stylized as NEKO#ΦωΦ), a famous streamer on iM, and Robo Head (stylized as ROBO_Head), an AI robot. One musician, Aesir (stylized as Æsir), decided to hold a large virtual concert in Node 08, one of the many nodes in Cytus. As more and more people used the virtual Internet, more and more musicians held concerts on iM, a social networking service.

The story is told in-game through various cutscenes that are unique to the chapter title songs individual songs within each chapter are at most only marginally relevant to the plot, except for a limited few.Ĭytus II, the sequel to Cytus, takes place about seven hundred years after the establishment of the virtual Internet space Cytus (stylized as cyTus). The plot features the disaster and the protagonist's struggle with identity. Due to limited memory space, human emotions are stored in the form of music in 'Cytus', and by playing the songs, the robots are able to revive their human emotions. The story revolves around the protagonist, Vanessa, who lives in a 22nd-century world where robots with human memories are the only remaining sentient beings while living humans are killed by a mutant virus.

The story of Cytus is carried through its 10 main chapters as well as a prologue.
