Epsilon

Epsilon (イプシロン) 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.

Appearance

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.
