Ayumu Hoshino is the adorable younger brother of Kazuma. An affectionate little boy, he moves with Kazuma into the countryside on behalf of his asthma and meek health, and like his older sibling, enrolls in school. Much like Kazuma, Ayumu is friendly, altruistic and gregarious. Of his many hobbies, Ayumu enjoys drawing. [From Wikipedia.]
