Galileo (ガリレオ Gari Reo) is the new "goldfish life" the protagonists are now living in and settling for protection. It is the airship that Hozuki Ferrari built in order to escape from Tuscany, Italy's sky pirates and the organization, Messier. It is also home to the three sisters, including Anna Hendrix.
It is also named after the famous inventor, Galileo Galilei. At first, the protagonists seem to call this airship the "goldfish", but Anna Hendrix stated that they are the descendants of Galileo and it should be named after him.
The Galileo (it's center) is sphere shaped. This is where Hozuki and the rest controls for seeing attacks with a big window screen.
It also has few basic structures. For instance, the person who is using the mechanic can use some device that is screen-like to track and examine things. The user will also have to use the handle to control and fly the mechanic.
