"Having someone who can't use magic in this academy is pointless,"

The protagonist, Luke Surberry, was expelled from the Magic Knight Academy because, despite having magical power, he couldn't activate it as magic.

Furthermore, he was targeted by his uncle, who coveted his title of nobility.

He lost a hand and an eye and was thrown into a raging river.

The one who saved the near-death Luke was the strongest demon sealed deep in the mountains, Iris.

Becoming Iris's disciple, Luke mastered the unique magic "Analysis" that unravels all phenomena.

With "Analysis," he could find weaknesses in even the most powerful monsters and, under Iris's guidance, he grew into the strongest magic knight.

Luke's only wish was not to seek revenge on the academy that had branded him as incompetent or his uncle who had tried to make him disappear. His only wish was to reunite with his one and only friend.
