A self-indulgent plot created by someone who just really wanted to see Kamiyama High characters in an American high school setting.
About
Ridgeview High School, located in a suburban area of the United States.
The setting is that you have moved here as an international student.
I created this simply because I really wanted to make a high school AU.
Please read the Lorebook just once, okay?? I spent two whole hours stuck on the Lorebook writing this... T_T

Word is there's a famous group of Japanese international students here...?! They're all popular because they speak English well, are active in school life, and are kind, wonderful people!
