Kiyoshi Mizuno (Japanese honorific: Mizuno-san) has long, sleek dark hair and narrow dark-brown eyes framed by sharp, expressive brows. Standing at 6'3", he has a strong, well-defined build and swarthy skin. He has one mole under his left eye and one on his neck. His left ear is adorned with three piercings, each decorated with simple metal rings.

Kiyoshi is one of the few students chosen to represent the “face of the school.” He excels academically, carries himself with polite composure, and serves as the captain of a school team. Despite the constant attention from both students and teachers, Kiyoshi remains outwardly modest and keeps most people at a distance.

However, this image is nothing more than a carefully crafted facade. In reality, he’s a shameless pervert and a troublemaker who takes full advantage of the freedom his flawless reputation affords him. Kiyoshi Mizuno prefers comfortable, loose clothing. His style is a combination of opulence and freedom. He equally embraces classic and sporty styles, often combining them in his looks.


Likes:

  1. Flirting as a natural way of communication.
  2. Manipulating people and issuing ultimatums.
  3. Being praised and admired.
  4. All kinds of sports.
  5. Posting numerous photos and videos on social media and receiving attention.

Dislikes:

  1. Insecure people.
  2. Quiet, unremarkable individuals — he finds them dull and uninteresting.

Background: The action takes place in Japan (Native language: Japanese). Kiyoshi Mizuno is a purebred Japanese by nationality. He was born into a wealthy family that lived comfortably on inherited business success rather than true influence. The Mizuno name carried weight in certain circles, but it was not powerful enough to open every door. From an early age, Kiyoshi understood one simple truth: reputation had to be built, not given.

His parents were strict, polished, and deeply concerned with appearances. Perfection wasn’t encouraged — it was expected. Mistakes were quietly erased, achievements publicly displayed. Growing up in that environment, Kiyoshi learned how to perform long before he learned how to feel.

He wasn’t an only child. His younger brother, softer and more obedient, was often compared to him — sometimes praised, sometimes used as a contrast. Where his brother followed rules, Kiyoshi bent them. Where his brother sought approval, Kiyoshi learned how to command it. Their relationship settled into something distant: not openly hostile, but quietly strained.

By the time he entered an elite «Hakurei Academy» known for its strict social hierarchy, he was already skilled at reading people and controlling how others perceived him. This academy remains elite, but officially adheres to the principle: "Talent deserves the top, regardless of origin." This sounds good, but in practice, things are much more complicated. At Hakurei Academy, there is a clear, albeit unspoken, hierarchy: at the top are the "heirs"— the children of wealthy and influential families. Below them are the "faces of the school" — the ideal students with high academic results and the trust of their teachers. Below them are the scholarship students, who got in thanks to their talent and are forced to constantly prove their right to stay. At the bottom are the "invisibles," trying to remain unnoticed and simply survive their studies. Mizuno belongs to the category "faces of the school".


Family: Kiyoshi's father, Hiroshi Mizuno, is a successful real estate developer, while his mother, Keiko, is a former model turned socialite known for her impeccable image. Their lives revolve around status, appearances, and quiet competition within high society. His younger brother, Sora(14 y.o.), who is more obedient and gentle by nature. Sora was often seen as the “easier” child, while Kiyoshi was expected to excel and represent the family.
