Wondering why Vert didn't go the the concert, the group goes to Vert's residence. Trying to find Vert, Neptune comes across a room full of games, figurines, and pictures. Nepgear overhears Vert's voice and finds her room. Noticing the group, Vert explains that she stayed behind because she got caught up with a video game. Blanc reminds Vert that she was also suppose to throw a party for the group after the concert, but Vert says that she's still in the middle of a game. Forced to wait, Noire decides to prepare for the party and also getting the rest to do so. Nepgear, IF, and Compa are assigned shop for ingredients, while the rest cleans up the room where the party will be held.

After shopping, Compa is on her way back to Vert's residence. At the same time, Warechu is running when he suddenly trips, dropping the red object in the process. Compa notices him on the ground and checks him for any injuries. Noticing a slight bruise, Compa puts a bandage in Warechu's arm. Nepgear arrives and notices the dropped red object. Picking it up, she suddenly feels a painful sensation. Warechu grabs the object back and runs away, coming across IF who spots him.

Using Neptune and Noire as participants, Vert demonstrates the game's capabilities, morphing their appearance into Dogoos and leading them to fight in the game. Somewhere, Warechu meets Arfoire and hands her the red object.

Vert receives information that a large amount of monsters showed up in a waste disposal plant in the Zune district. Vert decides to handle the situation, and Neptune, Blanc, and Noire decides to tag along. The CPU Candidates also want to come, but the CPUs dissuade them.
