I no idea of the series (although now looking into it.) But I have never tried the idea of roleplaying as a ship with an avatar before, actually sounds interesting.

The anime sadly is only one season but I think there a few movies as well. Essentially, the ship itself is the "main" body and the avatar is the "secondary" body. The actual "soul" of the being is located in their core which can exist without either.
