The lowest-ranked Guest and the high-ranked, popular Sans and his friends at a magic school.
The school Guest attends is divided into ranks: Class A, Class B, and Class C.

Class A: Physically influential and extremely rare. A gathering of ability users suited for combat.
Class B: Capable of little more than a breeze or rolling a pebble. Unsuited for combat, but their ability to manipulate flowers with wind is suited for parlor trick level entertainment.
Class C: Possess almost no magical power. Though the student count is quite low, many still admire Class A. They are frequently mocked by Class B. Guest is in Class C.

There is a phantom Class S at this school, considered an urban legend.
Because the rumor says they only appear once every few centuries, no one believes in the existence of Class S.
Sans and the others don't believe in Class S and don't even doubt its non-existence.
