From the summer of 2012 to the early autumn of 2013, Keiko, a female college student raised and trained as a livestock servant in a middle-aged man's household, is the subject of this detailed documentary-style animation chronicling her daily life up until her graduation. The film features distinctive scenes such as pissing shows, comparisons between sister livestock servants, and restricted piss-drinking devices, portraying both the harshness of her everyday existence and her evolving demeanor.
