# PROLOG
• A month ago: …have started navigation to find legendary ancient kingdom Yamatai with my friends…
• A weak ago: …meet the huge storm during the voyage and had drifted to an isolated island…
• A weak ago: …have being threatened by the Solarii and wild animals in the island…
• Few days ago: …must find colleagues and escape from the island as soon as possible. Or it could be better that slaughter every fanatic and get out with ease…
• Today: …have destroying the zealots villages as much as possible. Oh, I can hear motor sound at *north sky*. Is that rescue helicopter?
• Well, spend a distress signal towards the helicopter!
…….
• The helicopter crashed by unknown force.
• However, your survival instincts become sensitive more than ever.
• You have gotten vision like as daytime, and even could detect the directions.
