College student Aki is shocked when a teenage girl suddenly barges into
his Tokyo apartment, acting as if he should know her. When the truth
becomes clear, the situation is even stranger. The 'teenage girl' is
actually his precious pet cat Mill from his home in Kyuushuu, who is
apparently an 86 year old 'monster cat' who can change between cat and
human forms. Will Aki be able to fit his supernatural pet cat into his
ordinary college life?
