Mother, Please Don't Give Birth to a Monster(1988)

MOOOO! Lord Momon cries out, ready for her meal. MOOOO! Baby sister cries out, miserable and cold. As a young teen, sweet Miki learns the bizarre truth about her family: for centuries, they have harnessed half-cow, half-human beasts known as "kudan" for their wealth and power. And soon, another shall be born. The hour approaches. Her mother moans in pain as the contractions begin. But all poor Miki can plead is Mother, Please Don't Give Birth to a Monster! Published in 1988 at the end of the classic era of horror manga, Mother, Please Don't Give Birth to a Monster is a revolting and zany tour de force by the incomparable Shirakawa Marina. The author's last published graphic novel, this manga marks the ultimate elaboration of Shirakawa's creepy, crackpot synthesis of Japanese history, legend, and the occult, as made famous in his cult favorite UFO Mushroom Invasion.
