Sandworm

Enormous worms that inhabit the desert region.

At first glance, they seem to have the appearance of a monster from the age of former mamono lords. Inside their mouths there’s a part that looks like a tongue or bait in the form of a beautiful woman, but the woman part is actually the main body. They can move freely as if swimming through the sand, and when they dive into sand, by closing the part that’s like the mouth of a monster, they can store their soft, sensitive main body inside and protect themselves with the shell that’s like a rocky surface.
