Zeta

Zeta (ゼータ) (Ζήτα) is the sixth member of Shadow Garden, being one of the original Seven Shadows. She usually travels around the world alone gathering intelligence.

Appearance
Zeta is a female beastkin with blonde hair, large cat ears and a long tail. She wears the customary slime bodysuit with a large cape and an area exposing her cleavage.

Personality
Despite being part of the beastkin race who are mostly well-known as wild and dumb brutes, Zeta is smart and level-headed. She's shown to be a lone-wolf as she usually does her missions on her own.

From the anime's depiction of her, Zeta appears to be a tomboy who likes fighting, similar to her fellow Beastkin Delta. However, she seems to have a greater degree of self-control compared to the "loose cannon".

Like her fellow beastkin, she also dislikes undergarments as she finds that they restrict her movement and thus does not wear them.

Assault on the Order
During the kidnapping of her lord Cid's sister, Claire Kagenou, Zeta participated in the assault on the place where Claire was kidnapped along with her lord and the Seven Shadows. in the end they managed to rescue her.

Powers & Abilities
It is speculated that Zeta possesses less strength compared to the "berserker" Delta, but in turn has more self-control. She specializes in reconnaissance and tracking between the Seven Shadows and the other Beastkin.

Delta
Delta and Zeta do not get along well and constantly bicker with each other. This seems to mostly stem from their animal instincts, as Zeta is a Beastkin Cat and Delta a Beastkin Wolf, causing them to refer to each other by the mocking names of "Cat" and "Doggie" respectively.

Cid Kagenou / Shadow
Nothing is currently known about their relationship.

Nina
Nina is one of Zeta's subordinates within Shadow Garden. After Claire began displaying symptoms of having become Diabolos' host, Zeta had Nina infiltrate Midgar Royal Spellsword Academy to watch her.

Claire Kagenō
As the Shadow's younger sister, Zeta cares enough about Claire to have Nina infiltrate Midgar Royal Spellsword Academy to watch her after she began displaying symptoms of having become Diabolos' host.
