A virgin with no self-confidence.

Junichi Hashiba is a teenage high school student with no previous relationship experience, but has a good heart and can display genuine affection to those he cares about. He enjoys the lewd situations that happen trough the story and he is rather emotionally weak in the beginning, lacking self-respect and seeing himself in a bad light constantly. Throughout the show he's shown to grow as a person and learns to interact with those around him. He begins to understand more about his "gal' girlfriend and is willing to spend the effort needed to improve their relationship.

He's a good friend to the "three perverts".
