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 don't get along with well as the two constantly bicker with each other. That can be attributed to their differences in personality and Delta being a Beastkin Dog, while Zeta is a Beastkin Cat. Delta is often nicknamed "Doggie" by Zeta, while Delta calls her "Cat".

Cid Kagenou / Shadow
Unlike Delta who followed Cid due to his strength, Zeta was loyal to Cid due to his vast intellect.
