Just as Dreamcast, Saturn, and Mega Drive are finally about to graduate, Sehagaga's network gets taken over by... a Center-sensei lookalike?! Now with almost all their medals taken, Black Asobin challenges the trio to conquer his tower and face him head on, in order to get them back! Welcome to his Fantasy Zone... GET READY!
Dreamcast, Saturn, and Mega Drive team up with Sonic the Hedgehog to chase after Dr. Eggman through various dimensional warp zones, briefly passing through his Genesis debut and his first voyage in the third dimension, Sonic Adventure. With the Blue Blur on their side, the girls have Gotta Go Fast if they want to crack that Egg-Head wide open and stop the hacking for good!
Center-sensei hosts an exam in which the girls must go into the world of the arcade robot shooter game, Border Break, where they can win a large amount of medals. Saturn, the only one who has to go on foot, is made into a decoy for the enemy, while Dreamcast struggles with her controls, leaving Mega Drive to take on most of the enemies. But as they're about to reach the core, suddenly, an Egg-shaped menace rears its ugly head! But wait! What is this blue streak that's speeding by?
Dreamcast, Saturn, and Mega Drive must complete tasks to earn credit medals, but this time they don't have to go inside a game... Their task now is to use Puyo Puyo to create a new game. But here's the catch: anyone who comes up with a bad idea will lose medals! Saturn and Mega Drive think hard, but Dreamcast is the first to raise her hand...
Dreamcast, Saturn, and Mega Drive have come inside the world of Space Channel 5 to get the credits they need to graduate. They challenge aliens to dance battles with Ulala to save two friends of Center-sensei. But not only do they have to save them, they have to earn viewer ratings too. Saturn strips down to her bathing suit to help earn ratings, but things take an unexpected twist thanks to Center-sensei's friends.
