Green Village Kazamidai is an apartment complex that Tsubaki visits in Episode 8: Mysterious Sensation . It turns out to be his girlfriend Urabe's home, which he finds out when she returns from grocery shopping, to find him standing on the sidewalk and staring at the building.
After she invites him in for a cup of tea ( manga ) or a cup of coffee ( anime ), he finds out she lives on the tenth floor. Urabe has her own bedroom in the apartment, and has it decorated with items having to do with Si-Fi and UFO's. Urabe lives in an apartment with her family, but it is uncertain just who comprises her family, and why they seem to never be at home.
