Becoming a Shipgirl Was One Thing, but What the Heck Is a Space Carrier?

I, Li Mobai, was killed during a mission by my idiot buddy (reactor explosion).

Then I was knocked out and taken away by Bai, a catgirl who calls herself a "god," and turned into her little sister: the Demon Blade Mobai.

Bai: You're a mechanical life-form now! A War Doll, isn't that great? Demon Blade-class No. 4!

Mobai: ...Isn't that just a shipgirl...?

Bai: Wrong. You're a special model War Doll adapted to a ship's hull.

Mobai: Shipgirl...

Bai: ...

Then I was knocked out again, had some of my memories sealed away, and ended up in the shipgirl world, where I ran into my buddy again.

What reassured me was that this guy had become a shipgirl too.

And so began our daily routine of getting into trouble together.
