If there are any indisputable truths in life one is that everything is imperfect.
The Merriam Webster dictionary defines flaw as:
a: a defect in physical structure or form.
b: an imperfection or weakness and especially one that detracts from the whole or hinders effectiveness.
Even the finest, most well thought out, thoroughly engineered machines, computers, and creations in general will always have a flaw. Granted, the flaw may be undetectable, but it is still there. However, it is generally believed by engineers that there is one perfect design for a machine, based on the reality that when one person creates a design another is made that improves upon it.
Ancient buildings could never match the size, safety, and convenience of current architecture.
Cars from the 40’s couldn’t compete with modern day successors in any situation.
Even last years cellphone is inferior to its new model planned for next year.
And yet, despite having thousands of years of technological advancements humanity still has phones with idiotic autocorrect errors, self driving cars that merge into the back of dump trucks, and houses that can even have carcinogenic drywall!
These issues are generally unseen when hand-made by the original designer but one person can only hand craft so many things.
Enter Mass-production.
By definition, to produce a large volume of items requires sacrifice in quality. These products are not handmade with individual care, but rather are made via automation. That works well with a million products that are all identical to the next one in line.
But Neko are hardly identical. Different personalities, skills, quirks, and physicality.
The Star Army isn’t cloning an original template. They are creating people FROM an original template. In order to create such a diverse variety of people they MUST DEVIATE from the template, that design the creator felt was his best, most perfect design has been altered over a million times!
Is it any wonder there’d be overweight Nekos?
Perhaps the original might have been trim and boyish, but the original NH-33 isn’t in production. Of that there was only ever one. Now we are left with the automated system that is meant to deviate from said design to create an imperfect representation of the NH-33. But since nothing is perfect so is the original.
Thus we are left holding a paradox.
Yamatai can demand perfect but will have to sacrifice individuality in order to do so. They will never do that and in turn will continue to have overweight Neko.
So in conclusion, heavier Neko are not really a flaw of the system. Rather, it is the system itself that is flawed. In its purpose to make the ultimate soldiers it is not bound. It is creating people and not machines and therefore is not optimized for creating super soldiers, an exchange the SAOY has chosen for the many advantages that only truly living being can bring that no robot could ever dream of duplicating.
Nekovalkyrja are not the ultimate soldiers nor are they Gynoids. They are a species.
