The AR-Fields (ARフィールド AR Fīrudo?) are spaces between the [[Net Ocean ()|Net Ocean]] and the Human World created by Leviathan. They resemble a ruined version of the Human World, as they are simulations of the world Leviathan will create if it manages to take over it. Aiming at Rank Number One! Appmon Championship in Cyber Arena! The AR-Fields are the only place where Appmon can materialize without appliarising. Only an Appli Driver can enter an AR-Field using their Appli Drive.
