We open with Miyako, Satomi, the Shield Squadron, and the maintenance crew breaking through a barrier to reach a secret stash of equipment with which to continue the fight. Twelve hours earlier at Shimofusa Base, Satomi tells the Valkyries about this stash, located under Mt. Nokogiri in case of dire need.
Once again Azu is both frustrated and smitten with Miko’s determination to keep fighting despite the increasingly desperate odds. As for poor Sono, her last sortie and the loss of her Big Sis has rendered her too traumatized and distraught to get out of bed, let alone climb into a cockpit.
Satomi takes Azu aside to have her listen to a recording of General Okita’s last moments, during which Odin refers to such odd terms as “Valhalla” and “Asgard”. Azu isn’t familiar, but their resident Norther European Valkyrie and Odin’s favorite just might. Claudy, meanwhile, visits Lizbet, who recovers quickly, something she attributes to the blessing of Odin enduring even if his body was destroyed in the attack.
The bottom falls out of Lizbet’s heart when she hears Lily is dead, but tells Claudy that Yayoi’s last message to her was that Odin is hiding something and Claudy holds the key. Sure enough, when Azu asks her about it, Claudy recites something Odin once said about “Valhalla’s Gate” always being open to her. Sure enough, such a gate appears right there in the corridor.
The question now is should they move forward with trying to retake Takeyama with the Nokogiri stash, or go through the gate and explore Valhalla. The answer is, Why Not Both? Miko, backed up by her devoted Shield Squadron, volunteers to take Takeyama back on their own, while Azu and three escorts will accompany Claudy through the gate.
Just as they walk through it and it closes behind them, Sono appears, on her feet for the first time. At the sight of Miko she bolts but Miko chases her down. Sono is worried that every time she sees someone off it’s bad luck, but Miko takes hold of her and tells her not to think such things, and that there are ways for Valkyries to help even if they can’t fly.
As Claudy and Azu explore a grand, ornate and otherworldly corridor and Miko and the Shields prepare to sortie, Sono aids the civilian evac by helping out at the outdoor canteen. There, she’s approached by the two young pilots (lower-class Valkyries I imagine) from last week, who thank her profusely for, well, their lives, which they’re certain they wouldn’t have if not for her heroics. They vow to become “strong like her”, even though Sono breaks down after they leave, asserting she’s “not strong at all”.
Despite pushing back against the praise and gratitude of those pilots, hopefully it nevertheless helps nudge Sono closer to again stepping into a cockpit. It’s probably not a great idea at this point, but it may be necessary very soon, judging from what happens to her comrades. First, Claudy touches some rotating runes and starts to sing, then a nasty-looking golem appears, poised to attack.
As for Miko, she and her Shield take out a number of tertiary Pillars on their way to Takeyama, but there are simply Too Many Of Them, and they eventually clump together and coalesce into a secondary Pillar that totally envelops Miko’s Hero Wing. She’d flying through an otherwordly plane consisting of giant gears and strange eddies.
When the Gjallarhorn sounds, indicating the Pillars are heading towards Shimofusa, Sono urges the evacuees to remain calm, but one civilian woman collapses, having suddenly gone into labor. While the others have uphill battles with uncertain outcomes, Sono will have to do her best to help deliver the woman’s child. In other words, everyone is officially too busy to grief.
