"The Calamity Numbers"

It is the most formidable organization, comprised of nine individuals, each a match for a thousand, dreaded by all races—including humanity—and even the Demon Lord himself.

The protagonist, Cless Alicia, is one of the "Calamity Numbers" despite being only 15 years old.

One day, Cless is assigned a special mission by his boss: to infiltrate a magic academy as a student and monitor the Heroes summoned to the kingdom.

Despite his enthusiastic efforts to remain covert, his immense power inevitably stands out, and he quickly becomes famous at the academy. Even the Heroes he is supposed to be monitoring, along with royalty and nobility, end up taking a liking to him.

This is the story of a man who, despite being the most formidable sorcerer, is constantly misunderstood in a positive light.
