In a generic ancient China, Keirou, an evil general attacks a city on his own and wipes out the guards of Lotus Temple so that he can steal an ancient sword of power. The only person around to try to stop him is young Taitou, who is a highly skilled martial arts fighter, but even so Taitou is no match for Keirou’s power.
Taitou is the incarnation of a mysterious star that grants him a huge amount of power that he has yet to fully master. Joining them is Ryuukou, who has power similar to Taitou, just more honed. After Taitou’s coming of age ceremony, which required him being beaten by Ryuukou, he is given the Kenkaranpu, described as a conqueror’s sword, which Taitou is not even capable of drawing.
However, Taitou grabs the magic sword and, during his own power-up, is able to unsheathe the sword, demonstrating that he is the Chosen One. Keirou is ticked-off at this, and since he is an experienced Villain and Taitou is an inexperienced Hero, Keirou is able to trash Taitou and steal the sword.
Keirou and Taitou are only two of the seven super fighters who each have a sign of one of the stars of the Big Dipper located somewhere on their bodies. Taitou survives his battle with his powers intact and his temper on full power-up.
