Kazuma Hoshino

Kazuma Hoshino (星野 一馬) is the main protagonist of Hoshizora e Kakaru Hashi. A rather ordinary, though warmhearted teenage boy, he moves out of the city and into the countryside for the sake of his brother Ayumu's delicate health. His acclimation to this environment is an initially rough and humiliating one, attracting the ridicule and distrust of some of his peers; overtime however, his gentleman demeanor and true intentions earn him respect and even the ardency of his female companions. Partially unaware that his childhood took place in Yamabaki, Kazuma experiences occasional flashbacks.
