The Treasure Hunt Game begins. The rules of the game are simple: find the rings hidden around the city of Shibuya.
Kaname and Shuka, who were together in Shibuya, are separated right before the event starts.
Kaname is teleported to a hotel and tries to escape its grounds to search for Shuka, but he is pursued by a battle hungry player and finds himself trapped inside, with the building sealed off.
Inside the hotel, he meets a young girl who calls herself Rein.
