A meteorite brings a terrifying species that has destroyed other planets.
The ocean is no longer a bountiful underwater farm, nor will it produce delicious seafood.
What crawls out of the sea instead are terrifying creatures.
Technological weapons powerful enough to destroy humanity become nourishment for those creatures.
What path can humanity take? Become their food? Fight to the death? Or place its last hope in that mysterious Phantom Spirit System?
…
Endless panic spreads among humanity, while Ling Yu, who has lived through this scene ten times, lazily pets a cat.
Youmi: “Ling Yu! The Sea Demons are invading!”
Ling Yu: “Don’t panic! Turn into a catgirl first so I can see!”
Youmi: “I’m just an artificial intelligence! I’m not a real cat!”
Ling Yu: “You’re a magical cat! Hurry up and turn into a catgirl!”
