Daily Life With A Monster Girl Wiki

An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatched. Most arthropods, vertebrates (excluding live-bearing mammals, reptiles and fish), and mollusks lay eggs, although some, such as scorpions, do not.

Reptile eggs, bird eggs and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatched, i.e., breaks out of the egg's shell.

Eggs laid by many different species, including birds, reptiles, amphibians, and fish have probably been eaten by humans for millennia. Popular choices for egg consumption are chicken, duck, roe, and caviar, but a wide margin the egg most often humanly consumed is the chicken egg, typically unfertilized. Eggs are also an important symbol in folklore and mythology, often representing life and rebirth, healing and protection, and sometimes featuring in creation myths.



  • Similar to normal birds, Harpies occasionally lay unfertilized eggs. The exact number can vary at the subspecies, with regular Harpies only laying one or two eggs about every few weeks, while Poultry Harpies lays several eggs nearly every day which is a hindrance to their daily life but not to the same extend as Pans, Satyrs, Minotaurs and Dairy Breed Centaurs with their lactation.
  • Unfertilized (or possibly even fertilized) Harpies' eggs are considered a prized commodity on the black market, whereby Kasegi in Chapter 14 thought to himself that he could get 3 to 5 million yen for selling Papi's egg.
  • Although there are many avian-like, arthropod-like, and reptilian-like Liminal species, Harpies are currently the only Liminal species officially confirmed to hatch from eggs.
    • Okayado once made an illustration showing that Killer Bees also hatch from eggs, but since this illustration was never included in the canon of the manga series, this detail has not been officially confirmed.
  • Although it has been confirmed that some companies like the Black Lily Advanced Materials Laboratory also deals in the sale of unfertilized Harpy eggs, it is not known for what the eggs are actually used. One possibility is that the eggs are eaten, but since Harpies are a sentient species, that would be more than morally reprehensible, even considering that the eggs are unfertilized. This is somewhat proven after Miia ends up boiling Papi's (unfertilized) egg by accident while cooking; once everyone else realized what happened, their reactions were primarily those of horror.
