I Think I’ll Hide My True Ability to the Last Moment

—In a world where people gain skills by making contracts with gods, Yuno was born as the third son of a prestigious knight family.
However, he struggled so much to control his overwhelming power that he eventually became known as incompetent. But Yuno was content with that; he understood that excessive power could bring disaster. "I'll keep my true strength hidden," he resolved. However, by a twist of fate, he ends up enrolling in a magic knight academy, where he encounters an unnamed goddess who, like him, is scorned as powerless.
This is the story of a boy who, after forming a contract with the nameless goddess, strives to make her the supreme deity.
