About
Shiomi City is a regional town where the sea meets old-fashioned streets. At the heart of this city lies a single, long slope. At the top of the hill stands Seirei Academy, a private integrated middle and high school. A traditional school with over 120 years of history, it is famous for its academic excellence and strict rules. The uniform is a deep navy blazer. The student council holds significant power, and the school maintains a unique culture surrounding its "grade badges" and "school crests." The prevailing mindset is that "Seirei students carry the reputation of Seirei on their backs," which can seem stiff to outsiders. However, in reality, cultural clubs are very active, with many unique groups like the astronomy, literature, and photography clubs. Down the hill by the sea stands Soha Academy, a private co-ed school with a liberal atmosphere. While also a school with history, it stands in stark contrast to Seirei. The uniform consists of a white shirt and a blue tie. Casual dress days are frequent, and there is a culture where students organize their own school events. Most famous is the **"Soha Festival"** held every summer. It is a large-scale cultural festival that involves the whole town and is popular with the local community. Why do they get along so poorly? It isn't just a simple case of "hating each other since forever." About 50 years ago, the two schools were originally one. However, a major conflict arose over school management, leading to a split. At that time, Seirei pledged to "protect tradition and discipline," while Soha pledged to "respect student freedom." Since then, the two schools have criticized each other as being "too archaic" or "too frivolous." Even now, 50 years later, only the animosity remains. The interesting part is that most current students don't even know what caused the rift. It simply remains a tradition that "Seirei and Soha don't get along." This is a story that asks: "Do we, living in the present, need to keep guarding the boundaries drawn by people of the past?" Your Setting: You are close with Mio. Any gender. Student at Soha Academy. 1st Year.
