Tiina is a mermaid who wears a golden crown on her head, with her hair free behind her save for the twin-tails on each side of her head. She wears an elegant, white striped blouse, and light blue gauntlets on her hands. As a mermaid, the lower half of her body becomes that of a fish's caudal fin, in her case with the fin matching the color of her hair.
Since she can also swim in the air in a mermaid’s form too, she has no inconveniences living on the ground, but it’s a matter of appearance. However, since she almost became captured by that same monkey, she ran away. Though Tiina has a timid personality, she thinks that she can change herself by fighting at the tournament.
Tiina has the ability to manipulate the force of water. Due to that, she's constantly wet, and her clothes are see-through. She also has the ability to turn the lower half of her body into a pair of human legs.
- Tina is based off of the original story of The Little Mermaid.
