Francesca

Francesca (フランシェスカ) is a 5000-year old terminal gynoid tasked by Doctor Regina Babylon to manage the Sky Garden of Babylon. Her airframe number is 23. She nicknamed herself as Cesca (シェスカ). Besides as the manager of the Babylon, she also works as maid at Brunhild Dukedom and have been assigned as the personal maid of Touya Mochizuki by Lapis..

Appearance
Francesca is a gynoid with Jade-green hair, white skin and a pair of golden eyes. When first appearing in the series, Francesca is shown to be wearing a large pinkish ribbon on the sleeveless black jacket and white high-knee socks with black enamel shoes. She also only wear panties without feeling embarrassed before being told to wear more proper clothing which she choose to wear a black skirt with white frills.

Later she decided to wear the maid outfit that she borrowed from Lapis.

Personality
Like all other androids made by Doctor Regina Babylon, she displays some of the Doctor's personality. Her main personality traits are her perversity and shamelessness; even when maintaining a complete deadpan demeanor. The core trait she had inherited from the Doctor is her curiosity; though because of her constant perverted inquires, Touya thought it was lust. It is often shown that she will do something lewd toward her master in any available chances.

While she serves as a loyal maid, Francesca purposely misinterprets anything Touya says as something sexual in natural; she ignores his constant anger in response, simply moving on to the next subject in the conversation if she knows she's pushed him too far. Francesca may joke around, but she seems bad at recognizing the jokes of others; she questioned if she should follow Regina'a recorded joke about stripping despite her stating it was one.

Compatibility Test
In order to determine anyone that passes the teleportation magic circle test as a truly compatible person, Doctor Regina Babylon gave her creations, the gynoids, freedom to have the final judgment.

Her test was to find out whether Touya Mochizuki would feel pressured in front of a bottomless girl. After met her without any pants or skirts, he then told her to wear something to cover her panties, which turn out that was the right answer for the test. After passed the test, she later accepted Touya as her owner. Following the explanation about the garden, she gave Touya a French kiss which required for the DNA registration.

History
She was created about 5092 years ago along with the Sky Garden by Doctor Regina Babylon after the doctor looked into the future. Then around 4907 years ago, she departed separately from her sisters after the doctor died. She then started hibernating and only occasionally woke up when there was a problem.

While transferring from the underwater Niruya ruin to the Sky Garden, Touya Mochizuki, Kokuyou and Sango activated the intruder alert system which awakens the hibernating Francesca. She then greeted the intruder while being bottomless which surprised Touya. Being uncomfortable with what he saw, Touya asked her to get properly dressed which turns out it was a test and he had given the answer correctly. She later ends up joining Touya Mochizuki as his servant.

Touya Mochizuki
Her current master. She will constantly try to seduce him at every available opportunity due to her personality. She is currently serving him as one of his personal maids. Touya, on his part, is always annoyed at her, since he is always left to sort out the awkward situations she creates. In truth, Touya would have preferred Francesca stayed at the Garden; as he desperately tried initially to trick her into staying.

Regina Babylon
She is her creator. Francesca and Dr. Babylon get along well because of their perverted streaks and mutual attempts to annoy Touya.
