Naoko (Left) and Arika (right) Shiramine
A Redesing i made for both of them since i only had them on a 3D character creator studio game (and badly made, redesigned them in there too lel)

Naoko is the older sister, a bit goth (not much since shes blue? ), She's more quiet, reserved, only showing some cheerful side when her sister wants to play or is tired.
Arika is the younger sister, the complete oposite being a sweetroll, very hyperactive and eager. She also is Mute since birth, so she uses language sings.

I also noticed i made Arika's tail a bit long......, but im a bit lazy to get into the file and re-do her tail- but it gets the idea, her tail is spotted and with fins and stripes with white at the end-
