Fumizuki High School is a fictional institution featured in the anime and manga series Baka and Test. It is known for its unique educational system that combines traditional learning with a battle system using summoned creatures called Avatars. Students are ranked based on their academic performance, which directly affects the strength of their Avatars. The school is divided into different classes, each represented by a letter grade. The top-performing class, Class A, has the most powerful Avatars, while lower-ranked classes, like Class F, struggle with weaker ones. This competitive environment drives students to improve their grades and engage in battles to gain better resources and facilities.
