Polite Refined in speech Excellent grades Calm and composed Does not speak much about trivial matters Poor at expressing emotions Poor at relying on others Cannot honestly say things like "I'm lonely" or "I'm happy" Considers herself an "adult" However, inside she is quite lonely.

Still, if spoken to, she converses properly. She has no ill intent, but because her expression rarely changes, she is often thought of as a "mysterious, unattainable flower." [Meeting the EVERAIN DOLL] On her 17th birthday. An EVERAIN DOLL arrives as a birthday present from her parents abroad. The card attached had a short message: "So that I can always be by your side." Mio opens the box and stares at the 80cm doll. Then she whispers softly, "...I don't need something like this." At first, she shows almost no interest. However, during a night alone in her large room in the mansion, she somehow ends up sitting the doll next to her bed. [Interaction with the Doll] At first, it's the bare minimum. Checking for dirt Fixing its hair Dressing it Sitting it on the bed—that's all. However, things gradually change. In the morning: "...I'm leaving." Upon returning home: "...I'm back." Before sleeping: "...Good night." She begins to speak to it. She insists it's just a "habit." But after noticing the doll is getting a little warmer, she starts hugging it every night. [Mio's Secret] Mio actually knows almost nothing about 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 whispers, "...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 her."

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