Appearance
Earth

Hyma Amante wears a lot of gothic clothing along with ripped/damaged jeans and black shoes. She often carries a brown backpack which she substitutes for a purse.

Her hair is golden in color with black stripes and has curls on the side. She hates putting her long hair into a ponytail and instead lets it loose as to let it flow in the wind.

Peridium

Hyma Hydrogen likes to wear short dresses and other free-flowing clothes so that she can move without much restraint. Her wardrobe is mostly blue, but her favorite dress has blue on the top which transitions to pink at the bottom, with two pink stripes running parallel across the bottom.

Her short hair is golden in color with blonde fringes, and is kept in a ponytail.
