The Treasure Hunt Game begins. The rules of the game are simple: find the rings hidden around the city of Shibuya. 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, he meets a young girl who calls herself Rein.

Kaname and Rein discover that the Florist is watching their every move with the building’s surveillance cameras. They join forces to undermine his plans by destroying the cameras while evading his henchmen. Unable to escape the henchmen, they decide on a desperate strategy that leaves them with only a twenty percent chance of survival!
