Apartment 707 is the apartment that Nana Komatsu and Nana Osaki lived in. The apartment notably has a western style bathroom with a clawfoot bathtub in it. Later on in the future after Nana Osaki leaves the apartment, the clawfoot bathtub was removed and replaced with a standard grounded tub. The apartment has a reputation among its neighbors of nothing good ever coming from it.
