Gil Hazard, president of the Hazard Foundation, is secretly Professor G, the leader of the evil Dark Hazard organization. He has designs on world domination, and has plans to use the power of golf toward this end; this is the Battle Golfer project. Yui Mizuhara and Ran Ryuzaki are two ordinary high school girls who just so happen to be golf prodigies, and so are prime candidates for the Battle Golfer project. They are abducted by Professor G, but are rescued by a mysterious man before they can be taken under his control.
Having escaped, Yui hears about a golf tournament being held by the Hazard Foundation, and suspecting more nefarious plans, she secretly enters the tournament to stop him for good.
