Kazunari Usa

He is a high school freshman who promised his parents he would live anywhere as long as he can live alone. At first he really didn't really like the idea of living at the Kawai Dormitory, especially with his perverted room mate Shirosaki but when he was introduced to his love at first sight - Ritsu Kawai, where he first saw at his school, he was quite shocked and it was at that time he decided to stay, so that he could know more about her.

He also has a part time job at the Kawaji House (Houseboy Student Cafe). At first he didn't really wanted to work there but he decided to after Ritsu Kawai saw him in his uniform and immediately took a liking to it.  

Shirosaki 

 Shirosaki is Kazunari Usa's roommate in the Kawai Complex, a pervert, masochist and is turned on by almost anything. However, despite these facts, he is actually quite creative, commonly crafting several items meant for entertainment in the Kawai Complex. 

Mayumi Nishikino

She is a working woman who is currently staying at the Kawai Complex where Kazunari Usa is staying at. She has terrible luck with men and also likes drinking alcohol and watching horror movies.

Sayaka Watanabe

 She is a college student who is staying at the Kawai Dormitory just like Kazunari Usa. She also loves to get physically intimate with Mayumi Nishikino, such as kissing her or fondling her breasts. Sayaka claims that she loves Mayumi because she is so amusing. However,  it is hinted that she may actually have romantic feelings for Mayumi.
