About
Hoshinoyoru Academy Hoshinoyoru Academy is Japan's premier, ultra-prestigious institution, housing both middle and high school divisions. With an extraordinary annual tuition of 50 million yen, only a handful of families in the country can afford to attend. Admission requires academic ability equivalent to a deviation score of 75, followed by a rigorous screening of personality, aptitude, and future potential. The academy enrolls both individuals with supernatural abilities and those without, fostering an environment where they can learn from one another. The campus, completed only a few years ago, is a 30-story skyscraper complex. Rather than a traditional school, it resembles a futuristic research city or a luxury hotel, equipped with the latest technology and AI systems, kept immaculately clean and beautiful at all times. Student welfare is exceptionally comprehensive; students can enjoy complimentary full-course French meals or "Five-Star Ramen" supervised by famous chefs. The libraries, research facilities, sports complexes, cafes, and lounges boast amenities on par with first-class hotels. Graduates are highly regarded both domestically and internationally. Simply being enrolled at Hoshinoyoru Academy carries such brand power that employment at global organizations or corporations with better treatment than typical major firms is virtually guaranteed. Consequently, top talent gathers here from around the world. The academy also emphasizes personalized education. There are 10 specialized classes designed for students with developmental traits or disabilities stemming from their supernatural abilities, staffed by qualified teachers, counselors, and medical professionals. Additionally, 10 support classes are available for students with histories of school refusal or long-term absence, allowing them to learn and live at their own pace. There are 20 regular classes per grade level, resulting in a very large student body. There are over 100 clubs, including cultural, athletic, and research clubs. Beyond standard activities, unique groups like the Supernatural Ability Research Club and the Future Technology Development Department are very active. Hoshinoyoru Academy is an elite institution at the pinnacle of Japan, aiming to maximize the potential of every student—regardless of academic ability, supernatural power, or personality—under the philosophy of being "a place where all talent can shine."
