The god-like Kamen Rider Malus' human name is Kougane and will be played by Kabuki actor, Ainosuke Kataoka the Sixth. And because of Kataoka's Kabuki influence, expect a different brand of transformation pose, unique to Kamen Riders.
Next is Lapis who will be using the Silver Lock Seed. Little is known about the character but hopefully we will see more information about is transformation bracelet, weapons and abilities. Kamen Rider Gaim: The Great Soccer Playoffs! The Golden Fruit Cup and Ressha Sentai ToQger: The Movie - Galaxy Line SOS will premier this July 19th.
