Truth attacks Ao who is rescued by Naru when he teleports him and the Nirvash to her side at Okinawa. Reunited once more, Ao and Naru discuss the situation when Team Harlequin appears and reveals that Truth's current form is affecting all people infected by the Scub Corals and for being the son of a Coralian, Ao should stay away from him. Regardless, Ao decides to join his companions against Truth. Meanwhile, back at Eureka's timeline, her husband Renton boards the original Nirvash in an attempt to rescue her.

Truth and Ao fight for the Quartz Gun until it fires once more, erasing Truth and converting Ao's Nirvash into the "Nirvash Neo". It also rewrites history once more to render it like Generation Bleu defeated the Allied forces including Naru. As Naru is being hospitalized, Ao witness the Nirvash Spec V3 coming from the pillar and comes at its encounter, meeting his father Renton for the first time.

After having a brief encounter with the phased-out Eureka, Renton sets with Ao to Iwato-Jima where he thanks Toshio for taking care of his family and then decides to make use of the Quartz Gun to destroy the original Scub Coral at his timeline and prevent it from spreading itself throughout the dimensions. As Ao confronts him to stop it, he learns that surprisingly, Truth has not fully disappeared, but has become the Nirvash Neo's archtype instead. Ao then decides to make use of the Gun's last shot to change Eureka's fate and have her reunited with Renton. Because of it, Ao is transported to the year 2027 where he bids farewell to Truth and returns to Iwato-Jima to resume with his life, despite the fact that there's a chance that no one in the world remembers about him anymore.
