Neo-Amazoness

About 200 kilometers from the main island of Okinawa. Masahiro Sugiyama, a man in a business suit, is on a fishing boat heading to an isolated island at the southern tip of the Yaeyama archipelago. He's a very ordinary salaryman on his way to research to develop the island as a resort island. However, the island he arrived on was a busty tribe of only women. Sugiyama is attacked by Queen Luna and the Neo-Amazoness who rules everything. What is his fate!?
