The Nakikabane are large birds that live in the ruthless 2nd layer of The Abyss in the Forest of Temptation. They're carnivorous and quite violent at that. They're notorious for their capabilities to mimic speech and use it for hunting. If they capture prey with high social capabilities such as Hammerbeaks or humans, they will learn their prey's cries for help and use it to lure others thus giving them the name, Crying Corpses.
They live in colonies, and raise their chicks together. When they're at a young age and before they learn to fly, the elders will carry living prey to take them to their nest to feed the chicks. As one would expect from their size, they're quite strong, being able to swiftly carry a human around. During breeding season, they will purposely drive their prey to their colony and hunt them together. Delving into their colony is extremely dangerous, even for an adept Delver. Despite their scary looks and intimidating behavior, they are quite affectionate and chicks can be raised to be familiar with humans. Also, while their meat smells bad when cooked, it is incredibly tasty.
They have three eyes, one on the left side of their head and a bigger one in what would be the forehead. This gives them a superb spatial awareness, and they can respond quickly to threats coming from the sky. While they consume meat, they don't have a beak like most birds, so they rip out meat and organs using their tongues. Males have longer quills, so they can be recognized easily. With their wings fully spread, they can exceed 10 meters in width in some cases.
- In the English sub, they are called "Corpse Weepers" because of their ability to mimic the sounds their prey makes.
