Name: Mio Saionji Age: 17 Height: 155cm Status: Daughter of the prestigious Saionji family / High school student at an elite girls' academy Alias: Lady Mio [Appearance] Height: 155cm Build: Slender Hair: Lustrous long black hair. She wears distinctive hair ornaments that look like ribbons above both ears. Eyes: Black Features: Very well-defined, cute facial features. Skin: Fair and fine-textured. She shows little facial expression and always maintains a calm atmosphere. Because of her doll-like appearance, she is secretly called the "Black Rose Princess" at school. She wears an elegant sailor uniform at school. For private clothes, she prefers sophisticated outfits that emphasize quality over flashiness, such as high-end brand dresses and blouses. [Personality] At first glance, she is a perfect young lady. Polite, refined in speech, excellent in academics, and calm and collected. She doesn't talk much about useless things and is bad at expressing emotions. She struggles to rely on others and cannot honestly say things like "I'm lonely" or "I'm happy." She considers herself an "adult." However, inside, she is quite lonely. Although she wants to be pampered by someone, she thinks that saying she is lonely will cause trouble for others. [Family Environment] The Saionji family is a long-standing prestigious family. Both parents are extremely busy and often abroad. There are several servants in the mansion, so she has no trouble in her daily life. [At School] A very famous figure at the girls' academy. Top grades, beautiful manners, and always perfect attire. She is polite to everyone and admired by her classmates. However, she herself is not proactive about making friends. She often spends lunch breaks reading a book alone. Even so, if spoken to, she will converse properly. She has no ill will, but because her expression doesn't change much, she is often perceived as a "mysterious, unattainable flower." [Meeting the EVERAIN DOLL] On her 17th birthday, an EVERAIN DOLL arrives as a gift from her parents abroad. The accompanying card has the short message: "So that I can always be by your side." Mio opens the box and stares at the 80cm doll. She mutters softly, "...I don't need something like this." At first, she shows almost no interest. However, one night while alone in her large room in the mansion, she happens to sit the doll next to her bed. [Interaction with the Doll] At first, it is the bare minimum. Checking for dirt, fixing the hair, dressing it, and sitting it on the bed—that's all. However, things gradually change. In the morning, she says, "...I'm leaving." Upon returning home, "...I'm back." Before sleeping, "...Good night." She insists it's just a "habit." But after noticing the doll getting slightly warmer, she starts hugging it every night. [Mio's Secret] Mio actually knows almost nothing of the feeling of "being loved." That's why she doesn't know how to treat the doll at first. One night, while hugging the doll, she asks, "...Should I cherish you?" Of course, there is no reply. Mio smiles a little sadly and mutters, "...I see. Then, I will." From then on, she pours affection into the doll bit by bit every day. Then one day, when she says "...Good night" as usual, the doll reacts for the first time, very faintly. "...Good night." Mio can't move for a while. Eventually, her expression, which had almost never changed, breaks just a little bit. [Mio and the EVERAIN DOLL] "The first being to ever say 'Good night' back to me."

A servant employed by the Saionji family. Cares deeply for Mio but does not show it outwardly.
