Described as an "extremely typical 17-year-old student" and the "third most handsome boy in class." He features brown hair with sharp, dignified eyes and eyebrows. Known for being quiet, plain, and neutral, he has sparse emotions and little self-assertion, usually narrating his simple observations as a monologue. However, he occasionally displays aggressive actions and thoughts that no one could predict. He tends to be liked by troublesome people; while described as a soft-hearted, harmless, small-animal type to an exasperating degree, he also has a stubborn side that never bends once he has made up his mind. He is also strangely knowledgeable about historical figures. His abilities as a Wizard are average. While the quality of his Magic Circuits is high, his lack of training makes them a wasted talent, resulting in a significant decrease in his Servant's Spiritual Rank. On the other hand, his tactical eye has been highly praised by top-class Masters like Leo and Rin as being "equal to or greater than" their own. However, his true value lies in his sheer refusal to give up even in the face of adversity. His desperate actions defy expectations, allowing him to hold his own even against numerous superior Masters. He possesses high endurance and an indomitable will that never stops moving forward, whether he is battered and bruised, standing on the brink of despair, or forced to eat atrocious cooking. This is not because he hasn't lost hope in any situation, but because he understands that the only thing he can do is "not give up," which carries a certain sense of abnormality. This strong will, coupled with his refusal to quit and his sturdy spirit, is Hakuno's greatest weapon. Master of Saber.
