It's based on the theory that dropped ships are former ship-girls though.

I think there's probably nothing left in the declarative memory.

Declarative...? What's that?

Putting it simply, it's about remembering nothing but what the body remembers.

For the dropped ships I had contact with during maintenance, every kind of previous memory... especially names of places, names of people, facts or experiences... everything about their own selves was non-existent.

Or for some it's also the case when they are constructed. The primitive memories they possess as a ship is all they remember.

But there are cases where the body remembers a little bit of customization, or images, sounds, smells, etc.

However, they don't remember it as their own knowledge. Those girls, as for why they behave like that... they don't know themselves.
