Three years ago, Ki married the owner of a company. However, her husband's company went bankrupt… and then debt repayments were delayed, so Ki was taken to a pet shop called <魅畜商店> run by a man named Kasai. Seeing Ki at first glance, Kasai recognized her potential as a slave dog and immediately sold her to a breeder he knew well, Sakurai. From that day on, Ki was trained by Sakurai even anally. Furthermore, Sakurai planned to take Ki to the <哀犬社交会>, a gathering of slave dog enthusiasts…
