"Oh? Why is a commoner standing before me? I don't recall hiring such a menial worker. Or are you volunteering to be a servant for me, Mirei Ayanokoji? It's quite a bother, you know. I don't need any more underlings." Profile Attribute: POP Year: 1st Year Age: 16 Club: Equestrian Club Birthday: December 23 Zodiac: Capricorn Blood Type: B Height: 152cm Weight: 43kg Measurements: B73-W53-H80 Hobbies: Shopping Favorite Food: Caviar Disliked Food: Cup noodles Best Subject: English In a word, she is an "Ojou-sama." She is characterized by her long ringlet curls and a ribbon larger than her face. Being wealthy, she often travels abroad during winter breaks and other holidays. Although she is a first-year, she calls the protagonist (a second-year) her "servant" and greets him with lines like "Good morning, servant." However, regarding White Day returns for Valentine's, she shows a humble side, saying, "I don't expect a return that matches what I gave. Anything is fine as long as your heart is in it." She seems to be held in high regard by fellow first-year Yuka Koizumi, and they are often seen interacting. While she acts like a dominant sadist calling people servants, as your relationship progresses, she eventually switches to calling the protagonist by his surname, and finally by his first name. This subtle development showing her opening up is a charming touch present in most of her cards. However, since becoming close enough to call Yuka a friend, she has reverted to calling the protagonist "servant" more frequently. While her haughty and sadistic side is emphasized, her busy parents have been away from home almost every day since she was a child. To this day, she has almost no time with her family and harbors a lonely side that yearns for familial warmth. Due to her status, she has been surrounded by people using insincere flattery just to get to her parents, leading her to close off her heart and adopt a high-pressure attitude. The fact that she loses her composure around the protagonist and Yuka Koizumi—who speak to her directly as "Mirei" without caring about her family background—is proof that she has opened her heart to them. She works hard every day to live up to her family name. While she has a gap in perception compared to ordinary people, she is excellent in both academics and athletics. She is very strict about manners and is by no means ignorant of social norms; she is a capable person who can immediately handle and host sudden guests. In her final evolution of the permanent HR card, she is seen visibly flustered (labeled as [Flustered Ojou]). Perhaps because she is such an easy-to-read character, she has recently been teased more by the protagonist. Between having Rino Suzukawa's partner "Taisho" play with her hair, getting caught in equipment trouble, or falling into pitfall traps, she is establishing a position as a lovable "butt of the joke" character.

"...Hm? What is it, staring at my face like that? Is there something that bothers you so much? ...What!? The first-year area isn't here!? Are you an idiot!? I'm a second-year!"
