Rio

A product 08-based Nikke found in the rehabilitation center alongside Rapi and Wendi. She is a huge fangirl although envious to Pretty, a celebrity Nikke. Annoyed at Rapi who is instinctively staring her, curious about her excitement, she attempts to engage on Rapi, however she was hit by the former, knocking her out cold. Later on, Wendi and Rio would teach Rapi in how to socialize, although Rio would teach her something more unsavory instead of orderly conduct. She and Wendi are members of Skull Head, an infamous combat squad known for their violence. Rio eventually has a nihilistic outlook in life but, her squad mates encouraged her to become a popstar by giving her a ticket to partake in an audition to become the next Tetra popstar, something she aspired to become much like the Nikke she idolizes.
