When the Beach Picking Club finds a strange suitcase on the beach, their impulsive leader, Uta, uses its contents to accidentally sign them up for an experimental tech trial from the Forgotten Times. They soon discover they are not the first in their school to have access to the tech in question and many of their fellow students already are using it for their own amusement. The members of the Beach Picking Club want in on the games in the abandoned industrial district, but should they be playing with this tech if they don't know what it's truly capable of? Soon, another interested party appears, strange foreigners who will stop at nothing to acquire the tech, leaving Uta and her friends to fight for their survival.
