In order to be able to buy it you have to have at least 1 aquos bakugan and 2 darkus bakugan AND buy all the moves from darkess AND aquos you will find the style under "Multi" in the dojo
Aquos Macubass is spelled just as you have done .
Jenny uses an Aquos Siege and Jewls uses a Subterra centipoid
You have to beat Marucho using only aquos [water] bakugan after you beat the game.
Pyrus,Ventus ,Darkus ,Subterra ,Haos and Aquos
