Epsilon

Epsilon (イプシロン) (Έψιλον) is fifth member of Shadow Garden, being one of the original Seven Shades. Due to her insecurities with having a flat-chest, she manipulated her slime-body suit every year to slowly increase the mass on her chest, eventually, developing a fake large breast. As a consequence of this, she developed extreme magic control earning her the title, "The Precision".

Appearance
Epsilon is a tall young Elf with a refined, beautiful face. She has long light blue hair tied into pigtails. The color of her eyes are darker than the color of her hair. Epsilon possesses a curvaceous body that will make any woman envious.

In truth however, she actually has a slender but petite build and uses her slime suit to make her chest seem far larger than it is.

Personality
Epsilon was a prideful girl having been born from a noble family. Following her exile, she lost all care and only desires revenge against the people she once trusted. That all changed when she met Cid Kagenou who gave her new purpose in life and she fell in love with him soon after.

When she met the other members of Shadow Garden, Epsilon was dismayed how lacking she was compared to her more skilled superiors such as Delta, Gamma, and Beta.
