Asti was born in a winery in Moscato. After losing her parents, she was adopted by the Florentine family. Following a series of studies and assessments, she became an apprentice housekeeper, serving Florence since childhood.
The role of housekeeper for the Florentine family is a significant responsibility. Each housekeeper's final duty before retirement is to prepare their successor, a task executed flawlessly by predecessors until the sudden death of the previous housekeeper. At that time, Florence, having just become a duchess, received numerous recommendations for housekeeper candidates from within and outside the family. However, the duchess chose none of them, opting instead for Asti, whose only listed experience was "apprentice housekeeper" and who lacked any additional background.
Asti became the youngest person ever to assume the role of housekeeper for the Florentine family. Her appointment initially sparked criticism and caused those who met her to underestimate her due to her age and appearance. However, she soon demonstrated skills and sophistication that contradicted her youthful looks, rekindling the fear and respect people once had for the Florentine housekeeper.

Moscato grapes are one of the common grape varieties in Japh and are a specialty of Asti's hometown. While they can be eaten fresh, they are mostly processed into various wines and juices, becoming indispensable beverages in the daily lives of Japhians.
During the Oath Festival, only baptized Japhians are eligible to receive "Holy Wine"—a specially made grape juice used to give thanks to the Supreme Deity and honor Japhetic Ethics. This "Holy Wine" also symbolizes the blood of the Supreme Deity, with the belief that "He blesses Japh with His blood". Moscato grapes are a key ingredient in this sacred grape juice.
Asti received "Holy Wine" as a child. Perhaps due to the special production process or the deep-rooted piety of Japhians towards Japhetic Ethics, the "Holy Wine" far surpassed ordinary grape juice. The joy and unique taste of the "Holy Wine" left a lasting impression on her, though she eventually lost this privilege. As a result, Asti initially felt resistant to the ritual. However, without going into how she ultimately reconciled with it, it should be noted that she never blamed the grape juice itself from beginning to end.

Among the many responsibilities handled by the Florentine family housekeeper, hosting a grand banquet is the most intricate. Every detail, from the theme and guest list to etiquette standards, must be flawless. Most aspects are manageable, except for the guest list, which requires careful consideration due to the fluctuating status of the Japhian nobility, influenced by factors such as wealth. To avoid any social missteps, Asti personally created a guest list that she updates regularly.
Aside from the basic information in this list, it also includes some unpublished data obtained through special means, such as affiliations, illicit assets, personal habits, peculiar preferences, dark histories, and any disrespect shown toward the Florentine family. Asti has meticulously noted these details and, for reasons unknown, even added special doodles to many entries. As the list grows, it appears to be hinting at a possible vendetta list.

After becoming an apprentice butler, Asti's responsibilities increased. Besides the visible daytime duties, she also handled some family affairs under the cover of night. Many nights, she would secretly leave the Florentine estate and return before dawn, never leaving a trace.
As she became more adept at her tasks, she also grew fond of the solitude of night walks. Unlike the tense daytime, she could enjoy the different scenery that midnight offered.
During the day, Bellefontaine is a bustling art center, filled with crowds and dazzling light. At midnight, under the moonlight, it becomes serene, with the shadows adding depth and mystery, enchanting her.
Even on nights without tasks, Asti would go out for nocturnal strolls, carefully concealing her presence to remain unseen. She has occasionally invited a few people to join her, wanting to share the beauty of midnight Bellefontaine, saying, "Just by changing the time, the familiar world becomes entirely different."
Of course, these invitations are rare. Besides the hassle of covering tracks, not everyone is willing to sacrifice precious sleep for a nighttime adventure. As a result, the Florentine housekeeper has a significant need for coffee.
"Now that you know this secret, would you like to join me for a walk tonight? It's just one night without sleep.
