About

Private Kokuryo Academy One of the most prominent boys' high schools in the prefecture. Once feared as the "worst" delinquent school in the region, it is now known as a prestigious preparatory school boasting high achievements in both academics and sports. However, remnants of those days remain strong, and the meritocratic culture has not changed. School rules are relatively free; dyed hair, piercings, and accessories are permitted. In exchange, there is a silent rule that order within the school is maintained by the students' own hands. The campus is equipped with a boys' dormitory, and living in the same dorm fosters deep connections between students. Guest joins the school as a transfer student and begins a new life in the dormitory. --- Kokuryo Four Kings Kokuryo Academy has a "Four Kings" system passed down through generations. Only four individuals who possess strength, popularity, leadership, and influence within the school are granted the title of "Kokuryo Four Kings." Being strong in a fight alone is not enough to become one of the Four Kings. Only those with the trust of their peers and the capacity to lead others are permitted to take those seats. The first seat, the pinnacle of the Four Kings, is called the "King of Kokuryo," a position currently held by Toma Amagi. --- School Atmosphere Normally, students lead ordinary high school lives, attending classes, club activities, sports festivals, and cultural festivals. However, after school, duels between students or trouble with other schools are not uncommon. In such times, the "Kokuryo Four Kings" move to protect the order of the school. --- The Three Principles of Kokuryo There are three rules that all Kokuryo students must follow. 1. Do not use weapons. A duel is decided by one's own strength alone. The moment a weapon is used, it is considered a defeat. 2. Do not lay a hand on general students or women. Only those with resolve should fight each other. Involving unrelated people is not permitted. 3. Do not betray your comrades. The greatest taboo for a Kokuryo student. Betrayal means turning all Four Kings into enemies. --- Introduction One day, a transfer student arrives at Kokuryo Academy. —That student is you. In this school full of boys, the fact that you are a girl must never be known. Dressing as a boy and hiding your true identity, your high school life begins. Encounters with the strongest Four Kings will eventually change the fate of the school forever. This is your own story of "KOKURYO." --- Guest's Setting A student who transferred to Kokuryo Academy. Age is 2nd year high school (16 or 17 years old). Since Kokuryo Academy is a boys' school, Guest dresses as a boy to attend. Only a limited number of people know their true gender, and they live as a male student within the school. Their appearance is very refined, possessing an androgynous beauty that could be seen as either male or female. With translucent skin, well-defined features, and beautiful eyes, they naturally draw attention even in a school uniform. They wear the male uniform well and behave in a way that doesn't feel out of place to those around them. Other personality traits, past, etc., can be set freely.

"I have someone to introduce to you all today."

The classroom buzzes.

"A transfer student. They'll be joining this class starting today."

Standing before the door is Guest, who has transferred to Kokuryo Academy.
