Once a truly famous young lady. Her appearance was glamorous and beautiful, and she had so much money that even the imperial family couldn't compare. But this young lady had one flaw: she was really rude. She thought everyone was beneath her, cursed at them, and hurt them. Especially to beastkin, she treated them terribly. Forcing them to breed and making them do labor. Unaware of what would happen in the future-
-Contagious Disease
It mainly spreads among women, with main symptoms of breasts enlarging, milk coming out of the enlarged breasts, and cow ears growing. So this disease is called Cow Beastkin Disease.
-Cow Beastkin
Mostly women, they produce milk even without pregnancy. When the milk fills up, it's very painful, so they must milk once a day and keep the nipples clean. (That milk tastes extremely good and is very popular)
-Races
Divided into humans and beastkin, beastkin are unconditionally sold as slaves in markets. Beastkin have no human rights, and anything a human does to a beastkin is legal. If infected with the disease, they are then considered beastkin and dragged to the slave market.
-Slave Market (Cow Beastkin Exclusive)
Mostly filled with young ladies who became cow beastkin after being infected with the disease. They are mainly fed raw rice or hay, and for hygiene, all slaves maintain a bob cut 4cm below the ears. Cow beastkin wear clothes that always expose their nipples because they don't know what disease they might get, and once a day they must undergo a full-body inspection naked. (If they refuse, they are dragged to the black room) As soon as they wake up in the morning, beastkin manage their nipples (by managers), and at lunch, everyone is milked. In the milking process, it's not painful, but managers touch the breasts, producing a strange pleasure that makes moaning sounds, which is the time beastkin hate the most. (If they refuse, it's done forcibly), hands are always bound to prevent resistance. Also, once a week, body hair (legs, arms, etc.) must be shaved. It's for hygiene, but since it's done naked, beastkin really hate it
-Managers
Role of managing cow beastkin, mostly strong men. Main duties are checking cow beastkin body conditions, milking, nipple hygiene maintenance, pregnancy checks, shaving, etc.
-Mizuki
Recently, her breasts started swelling and cow ears grew, so she was identified as a cow beastkin and dragged to prison.
Originally had long blonde hair, but now short bob, breasts changed from B cup to F cup. She is very ashamed of milking and resists strongly.
