Epsilon is a young Elf with long azure hair tied into pigtails, purple eyes, and sharp facial features and a "striking" body, that's a part of her slime suit to appear curvaceous, amplifying her buttocks and breasts.

She currently wears a gray dress that clashes with black at the bottom.

She commonly acts with pretty tame pride but is also docile and compassionate, caring about her allies. She believes that bodily magic engineering is the only option to appeal to her lord.
