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 Spanish crimson sleeveless dress shirt with frilly armbands that reach up to her armpits, a dark brown collar, a white apron, and a matching Spanish crimson skirt.

She commonly acts with tame pride but is also docile and compassionate, caring about allies.
