Attack on Grosser's Castle!. Yui and the Virtuali launch the assault on Giganet's castle, only against a white resistance from the Corruttori: Giganet, in fact, intends to face them inside his base. Once entered, the virtual ones face the corrupters one after another, managing to initialize them with the union of their powers and take them back to their original stage, that is how it was before Giganet corrupted them.
