Nina/Relationships

Cid Kagenō / Shadow
Despite working outside the Shadow Garden organization, Nina feels a sense of fondness and respect for Cid Kagenō, much like most of the Shadow Garden girls. She is aware that Cid is Shadow, and willingly fulfills various tasks and requests he assigns, such as handling his homework and collecting information, among other responsibilities. Nina holds Cid in high regard and takes his words very seriously, much like the other Shadow Garden girls. She places Cid in a position of greater respect than Claire and her master, Zeta, since he is the master of all Shadow Garden.

Zeta
Nina respects and obeys Zeta well as her subordinate, even though she is affiliated outside of the Shadow Garden organization, yet operates as a covert agent exclusively to Zeta's command. Per her orders, Nina is a planted operative at the Midgar Academy meant to be friends with Claire and recently to be of service to Cid upon his enrollment.

Victoria
Nina and Victoria are contemporaries under Zeta's exclusive command, but the two seemingly have opposite personalities. Unlike Victoria, Nina isn't cold and abrasive while encountering others, but is routinely chipper and outgoing when with being social; such as befriending Claire or helping Cid or interacting with her classmates. However, it is unclear if such a jovial persona is her standard or a façade for her undercover work for Zeta.

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. In order to do so, Nina has since become Claire's friend at the academy.

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.

Alexia Midgar
Nina has been shown to have a degree of trust fro Alexia. As when the princess wanted to help Claire understand Aurora, Nina was ready to help Alexia helping Claire. Despite Alexia's "relationship" with Cid, Nina seems to genuinely care for someone she would call a friend.
