Queen's Blade

Every fourth year, the queen in the country is decided in a fighting competition, the "Queen's Blade." The most powerful fighter will become the ruler of country for next four years. Any female above the age of 12 with power can join Queen's Blade. It is a 1-on-1 game, although multi-player rules are included. Each player requires one game book from this series (or any Lost Worlds book, really). Each book represents one character and contains a character sheet. At the start of game, each player hands his opponent his book but keeps his character/action sheet. Then both players announce their character's action and resolve the result according to the books. The first character reduced to zero hit points loses the game. Part of the Lost Worlds series of books.
