| In 2020, mysterious alien lifeforms called Pillars appear, threatening the existence of humanity. When even nuclear weapons fail to destroy them, the world's leaders are left wondering how to resist. Suddenly, a boy claiming to be Odin appears, promising to help humanity battle against Ragnarök by providing Valkyries who have the ability to destroy the Pillars. However, instead of modern jet fighters, Valkyries fly magically enhanced propeller driven fighters. In 2025, after a successful but costly attack on a Pillar in Europe, S-class Valkyrie Claudia is transferred to Japan. On the way there she is ambushed, but is assisted by a local, inexperienced Valkyrie squadron. Later, when she arrives at the Tateyama Base, Claudia meets the pilots she previously encountered, Miyako, Sonoka, and Azuzu, who are members of the 909th Valkyrie Wing. Claudia believes she was sent there due to her reputation as the "Grim Reaper". Suddenly, a Pillar is detected approaching Tateyama, but since it is underwater, it is almost impossible to attack. Azuzu comes up with a plan to force it to the surface with explosives. Working together, the 909th are able to destroy the Pillar. Afterwards, the 909th and Tateyama Base staff officially welcome Claudia. |||||

However, a Pillar appears offshore near Umihotaru, creating a large barrier and trapping a number of civilians and one of Tateyama's reconnaissance helicopters. The Pillar is also slowly draining the life force of the trapped civilians, putting a time limit on when they can be rescued. Azuzu comes up with a plan to fly through an underwater subway tunnel, which will allow them to pass under the Pillar's barrier. Getting up close to the Pillar, Miyako is able to break its water barrier while Sonoka uses fire retardant to neutralize its heat barrier, allowing Claudia to destroy it. With the mission a success thanks to their teamwork, Claudia finally begins to feel that she can be a part of the 909th.

| The 909th are battling against four Pillars, which seem to endlessly regenerate when Azuzu's plane is hit. She then passes out after she makes an emergency landing. When she awakes, she finds out that the Pillars emit ultra high frequency sound waves whenever one of them is destroyed, which she surmises is them signaling to the other Pillars to help regenerate them. However, the Valkyries learn that one of the Pillars has appeared just outside of the base, cutting them off from access to their planes. Ronge, Kinpatsu, and Gurasan overhear the conversation and offer to help take them to the base, though everybody must wear swimsuits first. The trio then lead the Valkyries through a secret underground passage that takes them directly to the base. Once they finally reach the base, the Valkyries receive backup from another Valkyrie. They then take off to fight the four Pillars, and Azuzu instructs them that in order to defeat the Pillars, they must all be destroyed simultaneously.

At the base's bathhouse, Amatsuka reveals that they are at the base due to a counteroffensive against the Fuji Primary Pillar. Afterwards, Azuzu and Claudia leave to meet Odin. When a skeptical Azuzu confronts him, he assures her that the Fuji Primary Pillar will become inactive, leaving it vulnerable to attack. He then tells her what her glaring flaws are as a Valkyrie. When Claudia asks him about her transfer to Japan, Odin confirms that a replacement for Sakura was needed. The next day, Satomi tells everyone about how the counteroffensive will commence. Later, while the 909th and Amatsuka are eating lunch, Sonoka heads back to the base. Once Sonoka leaves, it is revealed that Miyako was trying to smooth things over between Sonoka and Amatsuka as Sonoka had a falling out with Amatsuka.

Sonoka overhears this and is outraged. Amatsuka explains that in a mission two years prior, she had a bad feeling about it and sabotaged Sonoka's plane. During that mission, their entire squadron was wiped out with Amatsuka barely surviving. Sonoka was deeply traumatized by the experience ever since. The attack on the Fuji Primary Pillar then commences, with the Valkyries being able to breach the Pillar's outer wall. The 909th fly into the breach, which seems to lead to an separate dimension. There, they find the wrecks of countless Valkyrie planes that had been shot down by the Pillars, and encounter a monstrous being that Odin identifies as Thor.
