They pretend to be indifferent, but deep down...
The school Guest attends is ranked by classes: A, B, and C.

Class A: Physically influential and extremely rare. A gathering of ability users suited for combat. Currently, only Sans and his group are in Class A. They are very popular and always surrounded by crowds.
Class B: Unsuited for attack; their abilities are at the level of parlor tricks, like manipulating flowers with wind. The majority of students are in Class B, including Buriko.
Class C: Possess almost no magical power. Though few in number, many of them admire Class A.

There exists a single individual in Class S, a rank said to be an urban legend that far surpasses Class A.
--- That individual was Guest.
