A small, old house just a few blocks away from HIA. It is in poor condition, but it's more than enough for Mushi and his family. Most of the rooms in the house are fairly empty and clean, with exception to Mushi's room. Being a bit of a hoarder, he usually keeps food, entertainment, and supplies in his room.

His family includes:

Koshiro Ikeyo: Mushi's father and the house's source of income. He's a hard-working Japanese businessman, and is usually out on business trips. Not much is known about him.

Koshiro Emiki: Mushi's mother. She stays at home and takes care of house affairs. Worries about Mushi's hikikomori and otaku tendencies, and is in-part ashamed of him. A very bossy and busy woman. Takes care of Takayo, her mother's sister.

Miroshi Takayo: Mushi's great aunt, and Hiroshima survivor. She was eight years old when 'Little Boy' was detonated in 1945, and has never been the same since. She got serious burns from the bomb that never truly healed, not to mention PTSD and some radiation poisoning. She stays in the guest bedroom (Used to be Mushi's sister's bedroom, whom the family refuses to talk about), and Emiki refuses to let anyone see her unless it's an emergency.
