In an unexplored region of China wrapped in mystery, Ryuhi, a boy, was born and brought up in high mountain tops. There he received instruction from his wise teacher, Juan. Though he was young, he made himself a master of Kempo. One day, his teacher Juan was attacked and robbed of the Secret Scrolls of Hiryu-no-Ken, of which he was the author. Ryuhi possessed the 6th volume of the Secret Scrolls, the Shingan-no Sho, or book of the mind's eye which Juan had managed to save. Ryuhi begins his journey to Shorinji in compliance with Juan's last request. Gengai, the bishop of Shorinji welcomed the little Ryuhi, regarded as one of the titans of Shourinji Kempo. Six years later, they received a letter of challenge from the Tusk Soldiers, a mysterious organization of enemies of the Shorinji. Ryuhi is determined to take part in the upcoming "World Tournament of Contact Sports" as a representative of Shorinji. His desire is to prevent the Tusk Soldiers from becoming champions of Contact Sports at the tournament. Ryuhi heard from Gengai that in truth it was the Tusk Soldiers who attacked his teacher and robbed him of the Secret Scrolls. As he leaves for the World Tournament, his thoughts are on his teacher Juan and keeping the fighting spirit burning. The game features combat in a variety of formats, such as kicking and using fireballs to repel monsters in scrolling stages, a system during one-on-one duels against Tusk Soldiers or a pair of martial arts tournaments where the player must attack a mark that appears on their opponent's body, or defend the area when it appears on them (this system is similar to Culture Brain's original Flying Dragon for the NES), and RPG-style command battles against monster bosses. When confronted by a Tusk Soldier or other otherworldly villain, Rick can change into a costumed superhero form or switch with one of his teammates. The player must switch to Flying Warrior form to use the characters' magic powers and defend themselves from the Tusk Soldiers' magic spells.
