From my Fantasy Mythologyverse

An extremely timid and shy young spirit, Aquairy rarely shows herself to others, using her ability to turn into water to hide at the first sight of another creature. In spite of this, she trusts Xela due to seeing his kindness toward others, and was willing to be friends with him.

Her true name is Celia, but due to her dislike of being called a nymph due to having a dislike of insects, she insists on others calling her Aquairy. Her antenna work as vibration sensors, allowing her to sense those around her in water.
