Coincidentally, I was drifted to land before I finally died.

And then...

When I opened my eyes, I have regained all of my memory until that point.

When I returned to my post at the base, everybody has forgotten who I am.

It's because three months have passed while I was out.

I don't know what was it that caused my memory to come flowing back.

But it wasn't being reborn as an Abyssal ship, because only as a ship girl am I able to experience the kaleidoscope.
