2070, the time has come for advanced nanotechnology.
A team of Japanese scientists, including cyber experts, nanotechnologists, astronomers, geologists and biologists, using their satellite systems, detected the appearance in the middle of the Pacific Ocean in an unknown way to an organically recreated floating island Shunevo.
Azure Avenue Building Company over the past twenty years has been engaged in a secret mission entrusted by the government, namely the development of high quality diving cyber suits from a special nanomaterial obtained during a revolutionary breakthrough in 2050 by a group of experimental scientists.
In the course of closed experiments of cyberspace synchronization with the human body and recreating a special atmosphere for life, the cyber suit has shown successful results in overcoming the force of water pressure, and now it is possible to descend much lower, to the very depths of the ocean.
Trained from childhood using the PADI (Professional Association of Diving Instructors) system, six friend’s of an already professional group of divers, by the suggestion of Japanese government, gathered at the headquarters of the Azure Avenue Building in Yokohamin to discuss the terms of a mission of special importance level, which only they can fulfill.
