Battle of the sexes? No way, this is more fun!!!
Ginji is a street fighter who lives for his next fight, and his reputation precedes him. One night while seeking his next battle, he runs across a big battle! A bunch of girls are fighting, but this is no ordinary battle! They are all wearing funny costumes and using strange weaponry, and better yet, they are all gorgeous!
Having happened upon this secret war, Ginji is introduced to the Jewel Knights. These three girls invite Ginji to join their crusade to defeat the evil organization Ragnarokkr, since they know he is a strong fighter. He agrees, on one condition: that he gets to play with the girls whenever he wants! Reluctantly, they agree, since strength and good fighters are important in the ultimate battles of good versus evil!
