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.” In Yamataigo (邪馬台語) they are called 猫ワルキューレ (nekowarukyūre).
All Nekovalkyrja citizens of Yamatai, regardless of their origin, are subject to a mandatory 3 years of military service in the Star Army of Yamatai, or the equivalent in direct service to the Yamataian government.
The main subspecies of the Nekovalkyrja is the Nekovalkyrja, Type 33, but many other subspecies and types were used in the past.

Nekovalkyrja were first created by The Pagoda no Uesureya Genetics Corporation (PNUgen). These first “nekos”, NH-2 Nekovalkyrja types, had been created to counter the new “Seraph” organic weapons when the Yamatai Star Empire had been at war with the Elysian Celestial Empire.
Notable NH-2 included:
Yui and Yumi were raised as babies, but later Nekovalkyrja were generally created as full adults. The first attempts at trying to make an artificial mind template for Nekovalkyrja who weren't raised as children were a mixed bag - some of them, like Eve, were psychopaths.
PNUgen, following on their success, created the NH-7 Nekovalkyrja Nekovalkyrja II, which saw even more production – and were eventually purchased by the WickedArms Industries Corporation and Ketsurui Heavy Industries, whom began producing NH-7 variants.
In YE 22, PNUgen produced the NH-10 Nekovalkyrja III (“NH-X”) and made them available as elite units to the Star Army of Yamatai.

In YE 22, shortly after the NH-10 finished its long development, WickedArms followed up with the NH-12 Nekovalkyrja, a miniature neko model designed as a personal assistant. They saw extensive use as pilots of Lamia M1 Space Mecha during the Second Draconian War.
The Star Army Research Administration, a branch of the Ketsurui Zaibatsu, eventually produced the NH-17 Nekovalkyrja Nekovalkyrja V from YE 23 to 27, producing in the span of four years a number of four-and-a-half-trillion models; making them the most common series yet which came in the 17R (regular), 17S (stealth) and the 17T (telepathic) variants.
The NH-17 was the main Nekovalkyrja of the First Mishhuvurthyar War.
More recent developments introduced the NH-22 Nekovalkyrja types, but instead of seeing mass-production, they only lasted for a prototype phase before they branched off into two variants whom became types of their own: The NH-22M Nekovalkyrja VI, originally designed to assemble most the the NH-17’s variants under one powerful package, was perfected and reclassified as the NH-27 Nekovalkyrja (Type 27); The NH-22C Nekovalkyrja VI, designed to be a civilian unit capable of child-bearing instead of a military-grade machine, was reclassified as the ‘Yamataian’ race under Nekovalkyrja Re-integration Plan. The NH-22C Yamataian were strongly advocated by the Yamataian Government to diminish the number of Nekovalkyrja combat units in an effort to integrate them into society when the Yamatai Star Empire was not in a state of war.
In YE 28, the NH-28 Nodal Integrated Weapon System saw the field. Rather than being an actual living creature, the NH-28 Nodal Integrated Weapon System pushed the weapon-aspect of the Nekovalkyrja series to the hilt, creating a cold killing machine designed as a ruthless counter the Mishhuvurthyar.
The NH-29 (now known as the NH-29) was made by the Star Army Research Administration as an answer to the NH-22C/Yamataians, so that the Nekovalkyrja could continue their own species instead of being absorbed by another. The NH-29 was based on the NH-17, but does not share most of their combat capabilities, settling for a revised, more robust physiology and relying more on power armor to provide for their fighting capabilities.
The NH-29 was the standard model Nekovalkyrja body used by the Star Army of Yamatai until its replacement by the Nekovalkyrja, Type 33 around YE 34, making it the primary Nekovalkyrja serving throughout the Second Mishhuvurthyar War.

The Nekovalkyrja, Type 33 design process began around the same time that the NH-32 was started in YE 32. The NH-3x as it was called was also influenced by the shifting role of the NH-29, becoming the primary ship-borne troops and the NH-32 specialized for Infantry. This shift is why the Tennyo is no stronger than the NH-29. With the NMX manufacturing their own NH-29 as soldiers and infiltration personnel, the designers wanted NH-33 easier to identify, starting with a change in the hand structure. Also a number of internal systems were modified, namely the cardiac and respiratory were based on the Minkan. The respiratory system was upgraded with the ability to store oxygen, to help improve survivability in situations where a ship's structural integrity was compromised, specialized for space service, and equipped with several security enhancements.
The reason the new NH-33 is called the Tennyo is to distinguish from the NH-32. Tennyo means Celestial Maiden, in Yamataian, and given that the NH-33 is primarily for Shipboard service, the name was considered descriptive of the new role.
The Designers from Star Army Research Administration and Ketsurui Zaibatsu carefully considered the various attributes of the various NH-Series to come up with a homogenous design. As the design work went on into the following year the project was renamed the NH-33. It became available in late YE 33.
Ketsurui Zaibatsu was surprised by the trend of NH-29 having younglings. Because of this trend, they decided to give the NH-33 (Tennyo) the freedom of choice regarding having children, without requiring a body transfer.
In YE 35, the Nekovalkyrja collectively were recognized as a legitimate species instead of just military equipment (bodies) being used by soldiers. Prior to this, the soldiers had no rights to their bodies. The ruling, Imperial Decree 20: Imperial Stance of the Rights and Restrictions on the Nekovalkyrja Species, was made by Her Imperial Majesty, Empress Himiko I of Yamatai:
“It is our view that the Nekovalkyrja, being a creature which can be created by not only by production but by natural birth, is indeed a species and we hereby decree that the whole Empire must treat it accordingly, and that the citizens of the Yamatai Star Empire who possess a NH-29 or NH-33 body are given the same rights are freedoms with one exception: as a military species created to be the protectors of Yamatai, we also declare all Nekovalkyrja citizens of Yamatai, regardless of their origin, are subject to a mandatory 3 years of military service in the Star Army of Yamatai, or the equivalent in direct service to the Yamataian government. This maintains the “veteran” status of the race which Taisho Yui explained is so highly revered amongst the Nekovalkyrja. This decree does not interfere with the Star Army of Yamatai's ability to produce Nekovalkyrja; the Star Army must continue to produce new Nekovalkyrja in any manner it sees fit.”
