Teddy Riner returns to comics with a new team and a totally different concept. Béka, the writer of Studio Dance and Rugbymen at Bamboo publishers, takes the reins. Teddy Riner, along with a troop of judoka children, must go to Japan to discover a secret maneuver, “Wrath of the Dragon”, a move mastered by only 3 old judokas. The trip will not be an easy one; many opponents are also striving to discover the secret in order to finally beat Teddy.
