The Sigur Berrentzs returns to Windermere for Grammier’s funeral and Heinz’s coronation. Hermann visits the site of the Dimension Eater blast to pay his respects and is joined by Kassim, Theo and Xao. Separately, Bogue visits the graves of his parents and three sisters and vows that everything will be over soon. Theo mentions that it’s been 150 years since a Singer of the Wind last sat on the throne, and Xao adds that Roid is going to use the coronation ceremony to announce the Globular Cluster’s independence. Hermann thinks it took too long to reach this point, and Kassim notes how many knights have died. Hermann adds that they painted their white feathers black and discarded their honor by using things like Var Syndrome. Theo thinks Roid will be able to use all these things to negotiate with the New U.N. Government. Hermann asks Kassim if he’s seen his family, and Kassim answers that he hasn’t. Xao points out that Theo hasn’t gone to see his fiancé, and Kassim explains that he vowed to not think about family until the war is over. Hermann rejects that idea and says that he visited his family and is expecting another grandchild. He says that no one knows when their lives will end, so they should say what they want to say and do what they want to do. Roid rides in a limo with Keith, who is now scarred and missing his right eye. Roid mentions how Keith was initially opposed to his plan, and now things might not go as they expect. Keith says that he’ll go along with Roid’s plan as long as he doesn’t betray Windermere. The coronation ceremony begins in a stadium with Heinz ascending stairs and thanking the Aerial Knights for their service to Grammier. Heinz asks Keith if he can still fly, and Keith answers that he can still read the wind. Heinz wishes they could serve together as brothers, but Keith answers that he’s a knight and that it’s his duty to protect the kingdom. Heinz responds that this will be the last time he calls Keith his brother. On the Island Jackpot, Mikumo tells Kaname that she might have an idea about retaking the Globular Cluster. Hayate, Mirage, and Freyja visit Rag-Nyan Nyan, which has set up inside the Island Jackpot and will be the new headquarters for Walkure. Chuck runs over and shows them a video feed of Heinz’s coronation, which is being broadcast in real time across the entire galaxy.
Roid addresses the crowd and states that Windermerians have never forgotten what happened with the Dimension Eater seven years ago. He says that they tried to show everyone the truth, but the New U.N. Government silenced them. Despite that, Grammier rose up and established the Domain of the Wind. Roid then pulls up a video from seven years ago of a NUNS VF-22S Sturmvogel II dropping the Dimension Eater on Windermere. Roid claims that NUNS dropped the Dimension Eater and blamed Windermere, and he points to the use of a reaction warhead on Ragna as further evidence of NUNS’ duplicity. He then declares that the capture of the Globular Cluster is only the start and that he intends to liberate the galaxy from Earth’s rule and establish a galactic civilization that exceeds the Protoculture. People in the audience are confused because they thought the war was going to end. Roid declares that this directive was Grammier’s final will, and the Aerial Knights voice their support. A platform then rises with King Heinz sitting on the throne. Heinz states that Grammier wanted Windermerians to be happy, and he pledges to establish a galaxy of peace. Heinz starts singing the Wind Song, which causes a Protoculture structure to appear below Sigur Berrentzs. The same structures appear on other planets in the Globular Cluster and emit Bio-Fold Waves that spread throughout the entire galaxy. Makina and Reina theorize that if the Wind Song were any more powerful, it could put everyone in the galaxy under mind control. Mikumo looks at the image of the Protoculture structure and has a memory of her dream. Roid is informed that a NUNS fleet is approaching Windermere. The fleet is using new fold jammers and is intercepted by the Aerial Knights. Hermann knows that Kassim doesn’t agree with Roid, but he tells him to stick to the mission. Keith’s Draken breaks off from the group and dodges a missile attack from multiple Nightmare Pluses. The Wind Song allows him to sense the wind, and he starts destroying the Stealth Cruisers equipped with fold jammers. With the jammers gone, the soldiers fall prey to Var Syndrome. Later, Delta Flight arrives at the battlefield and finds that the NUNS fleet has been completely destroyed. However, Hayate spots a single survivor and moves in to rescue him. Berger reports to Roid that all the Protoculture structures are operating normally. Berger mentions hearing that a request came in for peace talks and asks Roid if he refused. Roid answers that Earthlings aren’t worthy of the legacy of the Protoculture. Arad is surprised that the survivor is Robert Kino, and he’s equally surprised to see Arad. Arad asks what happened, and Robert explains that they were all destroyed in an instant by Keith’s Draken. Robert thanks Hayate and asks for his name, and he’s shocked when he hears Immelmann. He asks if Hayate is the son of Wright Immelmann, and Hayate answers that he is. Robert then turns to Arad and asks what he’s doing with the son of “that man.”
The war enters a new phase of escalation, as Roid declares war on the entire galaxy. He gives a propaganda speech that echoed Gihren Zabi in Mobile Suit Gundam, but the most interesting thing about it is that it’s built on a lie. As Grammier died, he called out for Heinz, and he certainly didn’t have time to tell Roid to conquer the galaxy. So even though no one else knows it, this is all Roid pursuing his own agenda and using Grammier’s name to push it through. NUNS attempts to fight back with the new fold jammers, but their quick destruction makes the fleet an easy target once more. The episode then teases a mystery about Hayate’s father, who he admittedly doesn’t know too much about.
