Aqua Heartfilia

Aqua Heartfilia is the second eldest daughter and third child overall of Lucy Heartfilia. Due to her mother being the Celestial Spirit Aquarius she is also half Celestial Spirit.

Appearance
Aqua is a little short for her age, sports long blue hair usually tied into pigtails. She likes to wear dresses and not show much skin. Compared to all of the adult Heartfilia daughters she has the smallest chest, one that virtually doesn't exist. In her human form she has a striking resemblance to the Eclipse form of Aquarius.

Upon coming into contact with water Aqua is forced to assume her mermaid form, her legs fuse and become covered in blue scales. There is no way to avoid this and virtually any amount of water, even rain, can make her transform.

Personality
Aqua is a kind girl with little to no bad bones in her body. Aqua has a slight personal sadness due to growing up with only one mother, Aquarius being lost during the original Tartaros Attack. As a result she finds herself naturally being closest to Lucy. Even then she still loves her spirit mother and wishs to reunite with her someday.
