Arachnea

Arachnea is a villain in *Yes! Precure 5*. Along with Hadenya, they are the only female employees of the Nightmare Company. Arachnea appears as a woman with short purplish pink hair wearing a business office dress. Her true form is that of a humanoid spider with six "legs" on her back.

Arachnea is overconfident that her abilities can handle the Cures easily. Each defeat is a stab to her pride which makes her become desperate to defeat them no matter what it takes.
