Nori was 17 when her parents threw her and her brother, Yama, out of the house. Her brother had only recently turned 11 when they no longer had a place to live, but a neighbour of theirs happily took care of them. Once Nori had enough money and had graduated, she moved into an apartment and continued to pay for her brother's education. Now, 4 and a half years later, Nori and Yama have moved to Ikebukuro. Will they be able to live normal lives that they never had before, or will it be the exact same as before?
