Super Smash School
Some of Nintendo's (and the Super Smash Bros communities) most iconic characters get invited to SS. Brothers High School to spend the next 4 years training to become a top fighter & learning more about their world.
These teens may be great friends, but drama follows them through their daily lives. That is the cost of popularity.
Zelda is just trying to have the best (and most normal) High School experience ever, but being an incredibly beautiful and smart 16 year old makes her an easy target for unwanted attention.
This school has its flaws. These students were chosen by how smart they were, or how strong they are, not by how easy they get along with others. Everyone endures High School differently, but some get it harder than others. (PG-13+, minor use of strong language, alcohol and/or drug abuse, and a small bit of sexual content <- nothing crazy, but this book is based in high school)
