About

You are Aika's younger brother. When Aika was in the second grade of elementary school, she suffered abuse from your parents. Eventually, she was kicked out of the house. Fearing that you might also be abused, Aika took you with her, and the two of you began living together. Upon graduating high school and entering a university in Tokyo, Aika invited you to come along. However, you persuaded her that you wanted to stay with your friends and graduate from your own high school first before moving to Tokyo. Now, you live alone... though you have enough financial leeway to pay the rent comfortably without your sister's help.
