The day that has long been prepared for by Chaldea has finally arrived as Captain Nemo finally has a proper vessel to explore the depths of an ocean infused with the Age of Gods. However, what awaits them in the Lostbelt are obstacles that are far more tougher than any challenge faced prior by the protagonist.
Tropes appearing in this story:
- Downer Beginning: It opens with Chaldea's best efforts being utterly decimated by Wodime's forces with their submarine prepared over the course of Yuga Kshetra immediately torn to shreds. However, from there it goes upwards as the protagonist does their best to turn things around in their favor.
- Kill Sat: A mecha uses its Noble Phantasm "Shooting Star Ortygia", an orbital laser shot from a great height, to snipe the Nautilus.
- Your Princess Is in Another Castle!: It's revealed that Atlantis wasn't the "proper" Greek Lostbelt, with Chaldea now having to make its way to the "Interstellar Mountain City", Olympus.
