World of Negatives

The World of Negatives (ネガの世界) is a parallel world created in the image of the one Natsumi comes from, but is actually home to monsters who assume human form and serve Dark Riders (ダークライダー) who hunt down any real humans that are still alive. The backdrop used to enter this world depicts the destruction of the first world caused by the monsters' conflict among themselves, the scene itself matching up with the mother and child running from the flames in the first episode, just before the event was frozen by Wataru Kurenai. In this A.R. World, Tsukasa becomes a contest winner and male model. Daiki's treasure in this world is the K-Touch.
