She's a demon with "two faces"normally, she is usually silly and nice, but when she spins around, her eyes glow red and she becomes a more malignant girl that controls water. Although she's a fan of Gaito, she thinks she has a better plan to catch the Mermaid Princesses than him. 

~!However she still fails and Gaito rejects her fondness for him due to her stupidity.!~

Such a responsibility doesn't leave much time for romance. But Lucia vows to protect her world and win the heart of handsome Kaito.
