Nina

Nina (ニーナ) is a a third-year senior student of Midgar Academy and Claire's best friend. She's secretly the personal subordinate of Zeta, but she works outside of the organization Shadow Garden and part of Zeta's faction in resurrecting Diablos.

Appearance
Nina is a human girl with long red hair, tied in a ponytail, with ornaments, blonde eyes, brown skin, with a cat or dog-shaped smile. She usually wears semi-revealing clothing and has a large and mysterious scar on the left side of one of her breasts.

Personality
At first glance, Nina may seem like the typical Gyaru type girl while she hides her smart and talented self as a cover to protect Claire. Nina is also seeming to have little sense of shame as she shamelessly talks to Claire and Alexia while only wearing in her undergarments, even she doesn't mind being seen with her breasts when her bra fell off later due to Claire.

Powers & Abilities
Nina isn't really good at academics nor ability at the Midgar Academy, but Cid notices that she hides her true prowess and that she's stronger than his sister Claire. She is proficient at regular tasks at the school level and routine work.

Despite not being Shadow Garden's official member, she is also talented at stealth and infiltration to help her lord, Shadow, and she has wood for paper figures. Victoria herself notes that Nina being able to challenge the Numbers, if she'd actually join Shadow Garden.

Cid Kagenō / Shadow
Despite working outside the Shadow Garden organization, Nina feels a sense of liking and respect for Cid Kagenō, like most of the Shadow Garden girls. She knows that Cid is Shadow, and she likes to serve functions and orders that he asks, such as doing his homework and gathering information, among other things.

Zeta
Nina respects and obeys Zeta well as her subordinate, even though she is outside of Shadow Garden.

Claire Kagenō
Ever since she was ordered to supervise Cid Kageno's older sister, Nina has apparently become very close to Claire by helping her whenever she can, in order to look after her and ensure no Cult member gets their hands on her.

However, despite Nina's loyalty towards Zeta, her friendship with Claire is genuine as seen when she became extremely worried when Claire was in pain when Zeta forcibly merges the right arm into Claire.
