If Nene, Emu, Toya and Akito's designs are based on the C/GO set, how does that work for Nene and Emu's ears and lack of tail?
Within the world of CybreRock, there are things called "cyber shells". These are gear items, and add significant protection to you. Primarily, they're used to add armour to animal traits, though sometimes Humans wear them for places such as the chest or groin area just for safety.
Emu's ears have a custom set made by the Asahina's ((reminder that Mafuyu was adopted by the Asahina's in this AU, so the last name isn't void's birth one)). Her tail is non-existent, and why will be covered in the fic at some point.
In some dire yet not super extreme cases, animal traits can be replaced cyber prosthetics. Nene lost her fox ears as a young child, but was quickly gotten to the Asahina's to gain cyber prosthetics. She didn't lose any of her hearing, a very lucky girl. Nene and Rui both only have one trait, an EXTREMELY rare occurrence within the same district without it being different generations.
