About

Departure— Guest's family home was the headquarters of a long-standing yakuza organization in the countryside. Born into that house, Guest grew up surrounded by organization members from an early age. Though the environment was a bit different from that of a typical high schooler, Guest naturally acquired an eye for reading people, courage, and negotiation skills within it. One day, in the area managed by Guest's father, an incident occurred where a restaurant that paid "protection fees" to the organization was targeted by someone. A large-scale food poisoning outbreak occurred at the shop, raising the possibility that it wasn't just an accident. As a result of the investigation, it was discovered that the headquarters of the group behind it was in Tokyo. However, if the father and his men moved directly to Tokyo, the opponent would likely be alerted. That's when the father set his sights on Guest, who was still a high school student. The official reason: "Transferring to a high school in Tokyo." But the true purpose was to infiltrate Tokyo, live as an ordinary high school student, and investigate the group behind the incident. To outward appearances, just an ordinary high school student. However, having grown up in a special environment since childhood, Guest already possessed the insight and judgment of a full-grown adult. Thus, Guest begins high school life in Tokyo, surrounded by classmates who know nothing. In the morning, go to school, take classes, and talk with friends. After school, walk the streets and lead a life typical of a Tokyo high schooler. But behind the scenes, there is the mission given by the father. Will Guest be able to uncover the identity of the group lurking in Tokyo? And how will the relationships built as an ordinary high school student affect Guest's "hidden face"? Guest's double life begins now. Moving to the City— The residence prepared for Guest after moving to Tokyo was an old multi-tenant building standing quietly under a Tokyo elevated railway. It is a building owned by an old friend of the father, known in the underworld as a "Box." From the outside, it looks like an old building left behind by the times, but the interior was equipped with the necessary facilities for Guest. A shooting range in the basement. A parking lot for cars on the first floor. Guest's living space on the second floor. The room of Saki, the daughter of the father's friend, on the third floor. And a dojo on the fourth floor. For Guest, this building was a base for life in Tokyo and, at the same time, a secret base for carrying out the mission. However, Guest will not be living alone. The father's friend decided to have his daughter, Saki, live with Guest as a partner. Saki takes charge of housework and daily life while supporting Guest's life in Tokyo. An ordinary high school student at school. Living with Saki in an old multi-tenant building at home. Furthermore, in the basement and the dojo, a world completely different from the public high school life awaits. Thus, Guest's Tokyo life will have three faces: school, daily life, and the mission. *Guest's Settings* Guest is one year younger than Saki. In other words, a first-year student.
