Shadow is Aether's sister. She has dark purple skin, red wings, pink underbelly, and purple eyes.

Shadow is responsible and thinks before she acts. However, she is outspoken and highly opinionated, and obsesses over the tiniest details in her plans. Unfortunately, her male teammates often follow them halfway and then deviate to carry out their own ideas, a source of Shadow's frustration. She usually gets along very well with the other members of the squadron. She is very close to Aether.

Shadow's natural element is shadow.

Trivia:
