Akira Shinozaki
The son of Kuwahara's former teacher and idol, he has a tendency to act without thinking. After ending up half-dead on Kuwahara's doorstep, he's allowed to stay in a spare room in exchange for chores and housekeeping until he can find a place of his own. It is revealed that, after his father's death, his step-mother asked him to leave home so that her son, a young boy who adores Akira, could concentrate on school entrance exams.
