The following morning Alcor surprises Hibiki, Daichi and Io by making breakfast for them, while Io withholds her fate from Hibiki and Daichi. Later, Alcor visits Yamato and expresses his concern over what consequences Io's death would have on Hibiki, although Yamato shows no sympathy for Alcor's anguish. Finally, Io is summoned by the JP's while Hibiki and co. are briefed on the Septentrione: Mizar's abilities of self-replication. As the group expresses concern on a battle plan, Yamato and Makoto reveal to their horror, Io inside a machine connected to the "Brionac" and their plan involving Io's sacrifice for Lugh. Furious, Hibiki demands another plan, although Yamato's logic trumps him. Finally Mizar manifests in Tokyo prompting Yamato to begin the summoning for Lugh. Simultaneously, Hibiki, Daichi and Hinako receive Io's death clip, causing Hibiki to storm out of the JP's headquarters. As Lugh manifests, Yamato assumes control of it and releases the Ryumyaku Seal at the Tokyo Metropolitan Government Building to envoke the Dragon Stream - Shakko, while at the same time Io's mind begins to erode due to the strain of maintaining Lugh. Makoto explains that Shakko connects to a parallel universe and hence, is the only thing capable of banishing Mizar before it replicates infinitely and consumes their own universe, which Yamato manipulates through Lugh and thus defeats Mizar, just as Io's mind collapses. As Hibiki arrives at the Shinjuku National Stadium, Yamato orders him to destroy Lugh (Io) who has now gained control of Io's body.
