SHUN'EI
Shun'ei is a manipulator of illusions. Due to his mysterious powers, he was abandoned at a young age by his parents and was raised as a disciple of Tung Fu Rue. Through Hakkyokuseiken training, he learned to control his hidden powers. As the last disciple of Tung, he has set out to challenge other fighters from all over the world with his close friend Meitenkun.

TUNG FU RUE
Tung Fu Rue is the founder of Hakkyokuseiken, which allows the user to freely manipulate "chi". Despite being a small, old man, he attacks through a powerful, muscular aura. He is not only the master of Shun'ei and Meitenkun, but has trained many fighters throughout his years. Even now he continues his lifetime of service.

MEITENKUN
Meitenkun is a sleepy young fighter who is always seen holding a pillow. Along with Shun'ei, he strove to train under the legendary Master Tung Fu Rue. His fighting style was named Hakkyokuminminken (Eight Extremities Sleepy Fist) by Tung. He conceals enough energy to earn himself the title of Tung's "secret weapon".
