Ena's "saleswoman" side, the red side, seems to have a more cheerful expression. She is often seen smiling when her face is tilted towards this side. She also seems to speak much more often with this side. This side of Ena is shown as energetic and calm, offering deals to potential customers. In one piece of merchandise, she is seen with a root-like object growing on her chest, which makes the red side take on a more neutral appearance, similar to the expression of her paler side.
The paler of the two is her "evil" side, which seems more serious, as she is often depicted with a slightly furrowed brow or a neutral expression, in contrast to her red, smiling side.
