Ena has wide, dark brown eyes that become a gradient into beige. She has short brown hair with medium-length bangs swept to the right. The left part of her hair is braided and tucked behind her left ear, tied with a short white ribbon. Her voice is sweet and airy. Ena is an extremely strong-willed person who always speaks her mind. Ena is also easily flustered and angered, and is described as a "tsundere" by Mizuki. While blunt and sarcastic in her words, she also has a caring and soft side.
