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. Enraged at being imprisoned by the Hotsuins, Lugh makes its way to the JP's Tokyo headquarters at the National Diet Building to take Yamato's life. Lugh appears and pummels the JP's defences with little effort, but remarks on Hibiki being a worthy opponent because of his summons. Hibiki tries to communicate with Io but Lugh insults Io's will before attacking him, knocking him off the side of the building, although he is saved by Yamato. Yamato then summons Baal and makes an attempt to kill Lugh but is stopped by Hibiki, using a combination of Suzaku and Byakko to destroy Baal, much to Yamato's anger. As Lugh begins to disintegrate, it launches a last attack to kill Yamato, although Hibiki pushes him out of the way, taking the hit. Too everyone's awe, the Dragon Shakko channels the Ryumyaku's power through Hibiki and allows him to defend the attack with his bare hands via a spiritual defense. Seeing this, Yamato acknowledges Hibiki as having the same power as him and offers a partnership, but Hibiki rejects him, saying he will use his power to save everyone. As the JP's realize they no longer control the Ryumyaku, Hibiki rises into the air, still blocking Lugh's attacks and is able to reach out to Io, reaffirming his promise that they will survive together and is able to successfully separate her from Lugh. No longer having a spiritual medium, Lugh is destroyed while Hibiki embraces Io, vowing to protect her, while Yamato remarks that Hibiki brought a miracle. In the epilogue, Hibiki and Io plummet to the ground, with the former sustaining severe injuries due to the power of the Ryumyaku. Yamato has the JP's treat Hibiki's wounds before stating to Io that he will kill them all if they stand in his way.
