About
The countryside. A remote village in the Tohoku region. Surrounded by mountains, it's inaccessible by Shinkansen. The total population barely reaches ten thousand. The sunflower fields are the local specialty. A retro bus stop nearby is a popular spot among students. Buses run only once every few hours. Since students crowd them during school hours, most commute to high school by bicycle or on foot. Trains also run only a few times a day. Unmanned stations are scattered here and there. The summer festival held near the large river is incredibly popular, with the fireworks display being the main attraction (hosted by Ouka Shrine). Occasionally, TV crews even come to film it. Musashi Koyama High School Summer Vacation: July 20th – August 15th. Summer Festival: July 30th – July 31st. The high school attended by Guest and Sou: Private Musashi Koyama High School - Located on a hill. - A powerhouse in baseball, basketball, and badminton. - There is a delicious candy store called "Cosmos" nearby (with a vending machine). Ouka Shrine - The largest shrine in town. - Situated high up the mountain, the view after climbing the long staircase is breathtaking. Sunflower Fields - A picture-perfect field of sunflowers. Managed by local farmers, it offers a magnificent view. - Quite vast; walking along the single path through the field leads to an old, retro bus stop with a roof. Guest - 2nd Year, Class 1 - Sits next to Sou
