Haruna is from The World of Narue. (The manga at least; I have the anime but haven't watched it yet, so it's possible she doesn't appear.) I'm not sure if it's supposed to be something that a lot of ships do, but she and another ship named Bathyscape both have human forms. (Bathyscape also turned part of herself into a house, if I remember correctly.)
It's kind of hard to explain Haruna's situation without being pretty spoilery, but I'll seize upon any excuse to mention the part where she poses dramtically with a ladle. '.'
(The other example, in case anyone wondered, is Kashimashi - Girl Meets Girl's Jan-Puu. Who my understanding is got the body as a sort of remote after they learned how to do it in the process of reconstructing Hazumu. Unlike her, the ships in World of Narue seem to be able make the rest of the ship disappear when not needed, and bring it out with no notice if needed.)
-Morgan, really wants more World of Narue manga..."I have no interest in ordinary humans. If there are any aliens, time travelers, or espers here, come sleep with me."
