The protagonist. Favorite phrase: economically sound. Seirin Academy Class 3-C. Years ago, his parents abandoned him and his little sister, leaving them with little money to their names. Unable to rely on any relatives, they live alone. In order to give his sister a comfortable life, he works several part-time jobs. He only relies on two things: his sister and his money. However, as long as money is involved, he'll work diligently and earnestly to earn his keep. When he's on the job, he slicks back his gloomy bangs to disguise himself. Thus, when he meets Emi to fulfill her rental request, she doesn't even realize that he's her classmate.
