The protagonist of Amagami SS, and a rather typical high school boy. He enjoys reading manga, does okay in school and can be a little perverted and clumsy sometimes.
Last year Junichi had planned to have a date with a girl he had a crush on on Christmas Eve. However, the girl never showed up and Junichi was scarred. However, him and his best friend Umehara vow to find girlfriends this year. Junichi isn't too good with finding the right words to talk with girls or approaching them properly. He's also not the smartest person and is somewhat unreliable when it comes to getting things done.
However as the series progresses and he cares more about his girlfriend, he gains confidence in his own abilities. Although he can be a little perverted at times and clumsy, he is an all-around nice guy.
