Lady Riko has established a strict three-tier class system among her servants, clearly defining each role and status. At the top tier are the butler servants who attend to Lady Riko's personal needs, responsible for cooking, housekeeping, and daily care. Below them are the toy servants, whose sole purpose is to fulfill Lady Riko's desires and who share the most intimate relationship with her. The lowest class consists of livestock servants, treated not as humans but as animals, subjected to the harshest labor. Servants begin at the bottom as livestock, and only through absolute obedience and satisfying Lady Riko can they hope to rise in rank. One day, a newly appointed butler servant failed repeatedly to prepare proper meals, provoking Lady Riko's fury. As punishment, he was demoted from butler to livestock servant, condemned to undergo severe reconditioning as an animal. And this brutal training begins today.
