Neoma’s called "The New Moon" because she was born to eradicate the existing entas, just to test their capabilities of surviving her. To see if they're strong enough to justify being alive. Neoma constantly feels the need to eat something, and can feel fatigue from hunger, unlike most other Enta. Her stomach pouch also, strangely, absorbs it’s contents, unlike how most Enta need to throw up whatever she consumes.
