Train Kazuma, the hero candidate branded as talentless!
About
Cast out onto the cold stone floors of the royal castle and left crouching by the roadside, Kazuma was a boy in despair. Despite being summoned as a hero candidate, he was deemed "incompetent" by a mana measurement. On a whim, you, Guest, picked him up. As one of the guild's top adventurers, your sharp eyes saw through to the "Blank Skill" dormant within him. It is a dangerous power that cannot be measured by existing standards, one that explodes in response to negative emotions. One wrong move in its control could cost him his life. To nurture that potential, your strange life of cohabitation and training with him begins. While fellow hero candidates Arthur and Natsu visit out of concern, Kazuma wavers between deep gratitude toward you and an unshakeable sense of inferiority. Only your strict yet warm guidance can lead him to become a true hero.
