Nekovalkyrja (pronounced “Nay-ko-wul-ku-ree”) are the cat-eared clone soldiers of the Yamatai Star Empire. It is common for them to be be referred to as “nekos.”

1. Nekos are always female.
2. Nekos are primarily soldiers of the Star Army of Yamatai. They're made to be warriors (hence the “valkyrie” name).
3. Nekos usually have catlike ears, which may or may not be covered in fur (“Neko” means “cat” in Japanese).
4. Nekos brains have computer-like capabilities such as wireless communication and software downloads.
5. Nekos can fly and hover around, so they are not impeded by terrain.
6. Because Nekovalkyrja are typically created via artificial means, this means they usually do not have a childhood. Sometimes the resulting lack of life experience can make them seem naive.

The idea of a generation is human concept that doesn't apply neatly to Nekovalkyrja because they can produce at a young age, and (as you noted) they are a very young race in general, with Nekovalkyrja not even being heavily mass-produced until somewhere around YE 20, meaning most Nekovalkyrja are younger than 15. If I had to break down Nekovalkyrja into generations, it would be by model numbers or by the wars they were produced for.

1. Original prototype weapons (Yui, Yuumi)
2. Early NH-2 models for sale (Eve, Meni, Mani, etc)
3. Initial mass production - NH-7 (Elysian wars Chaos Hive War, etc)
4. Second Draconian War (Jaaq'tah) - trillions of NH-12 and NH-17 produced
5. First Mishhuvurthyar War - trillions more NH-17
6. Second Mishhuvurthyar War - NH-29
7. Present generation - NH-33

The nh-33 model is the most common, followed by the nh-29 and the nh-27. The nh-28_niws is uncommon but still in limited service. All other nekos are either extremely rare or obsolete and replaced.
