Galilei Donna : Season 1

Hozuki Ferrari is pursued by unknown individuals at the same time that her two older sisters, Kazuki and Hazuki, are attacked by strangers. Although they have no idea why they would become targets, the police decide the situation demands that they guard the Ferrari family home. There, the Ferraris encounter unexpected guests...

Although Hozuki has successfully driven off Cicinho and his crew, the Ferrari family's relief is short-lived as the police suddenly draw their weapons and escort the family off to a holding cell. The only one to avoid detention, Hozuki runs in to a Galileo fanatic named Anna. After Anna tells her the truth behind the chain of events, Hozuki decides she needs to save her family.

Now international fugitives, the three sisters are forced to travel on the Galileo with Anna. Jealous of Hozuki's talents, Kazuki has a difficult time adjusting to their time together. As tension builds aboard the Galileo, an Aza Iron piloted by Roberto suddenly appears.

With neither food nor clothing aboard the Galileo, Kazuki is furious, and everyone's mood has hit a new low. They decide to go to Germany in order to break the impasse and find Galileo's sketches of the moon. Although they go shopping in disguise, the Black Ganymede finds them...

The Galileo sisters meet a ring of thieves called the Blue Hawk in a frigid Dutch village. Hozuki hits it off with one of the members, a young boy named Theo. Theo had built a telescope as a birthday present for another girl, Karen, and Hozuki wants to see how their romance unfolds, but...

Hozuki and Kazuki sneak into a hospital with Anna to get medicine for Hazuki. There, they run into Cicinho and Roberto, who had shot each other down from the sky. As the blizzard rages outside, a blackout causes rising tensions between the people inside the hospital.

Galileo Tesoro is revealed to be a tremendous energy source contained within Hozuki's hourglass. Roberto captures the Galileo in order to take the Tesoro from the sisters. The sisters put up a valiant fight, but they are no match for Roberto...

The three sisters continue their search for Galileo's sketches. Their next stop is Japan, where they visit their grandfather living in Kyoto. They gain a few moments' respite as Hozuki tries to finish a device begun long ago by Geshio.

The fifth sketch has pointed the sisters toward a desert in Libya. There, they find the sixth sketch. Once they decipher it, they should be able to learn what the Galileo Tesoro is... But an enemy suddenly attacks Grande Rosso!
