The ghosts and the curse being real were NOT the development I expected, at all.
Let us first stop to consider the absolutely ludicrous premise of re-incarnating barely-animate floating steel structures as self-aware girls in order to fight their internal demons that happen to be threatening humanity in the process.
Got it? Good.
Now... notice for a second that the ghost here has "SS-218" printed on its sheet, the hull number of USS Albacore, the ship that sunk Sazanami IRL. I'm willing to bet there's an un-summoned shipgirl here that's trolling Sazanami either for Shits & Giggles or because she is still a vengeful ghost but not quite Abyssal levels of vengefulness.
And so, Sanzami-chan's totally invisible to ghosts♪Unfair!Sazanamiiiii~
Where is Sazanamiiiii~
We've come for yooooou~Hmm?
What's that?It is no use.
We came for you as promised.
We shall take this as the proof.Ah! Sazanamiii!When did you get Kai-2!?With (1 min) of docking, Sazanami-chan's hair was fixed.Ushio...
