The is the version of reality where Kamen Rider Agito takes place. Similar to the World of Kuuga, the Riders and the police battle the Gurongi. However, a new evil surfaces onto the world, monsters that they refer to as the Unknown. The backdrop used to enter the World of Agito is the elaborate tapestry seen in the opening sequence of Agito that depicts the story of Agito and the Unknown. This story arc further expands on the war between the Unknown and the Gurongi, which is hinted in both their respective series and explained more outside them. Within this A.R. World, Tsukasa assumes the role of a mailman with Toko's letter on his person. Due to the similarities to the World of Kuuga, Tsukasa more or less possesses the same talents in this world, as well as knowledge of the Unknown and the Agito Seed. Daiki's treasure in this world is the G4 Chip, but it's eventually destroyed by Toko.Kamen Rider Decade episode "Reunion: Project Agito"Kamen Rider Decade episode "Awakening: Tornado of Souls"
