Fillonce

Fillonce is a mermaid and is an employee at Mermaid Cafe.

Appearance
Fillonce is a mermaid with a really clear blue almost white tail which has an agglomerations of white dot like markings. Her pink somewhat frizzly hair opens wide, her bangs curling to the right.

She wears a red bikini top.

Personality
Like all other mermaids, Fillonce is kind and caring, and is apparently fun loving.

Abilities
Being a mermaid, Fillonce has several abilities unique to her race. It is not yet shown but she may have the ability to talk to fish and call out to them using sonar waves, which is one of the basic abilities found in all mermaids and some fishmen. Apart from the ability to breathe underwater, as a mermaid she also has the ability to swim very quickly at speeds much faster than the flying fish used by the Flying Fish Riders. However, like any mermaid, she is vulnerable on land.

She also appears to be a skilled dancer, as she is dancing during the banquet for the Straw Hat Pirates.

Meeting the Straw Hats
Fillonce and her friends first appeared in Mermaid Cove, welcoming the Straw Hat Pirates when Keimi brought them there for a visit. When the three princes arrived to inquire the crew's illegal entry into Fishman Island, the mermaids denied the crew was there, hiding them. However, when the crew's presence were made known anyways by Sanji's nosebleed and Hammond's attack, the princes made it clear that they were simply trying to deliver Jinbe's message to Monkey D. Luffy.

An Unpleasant Surprise
Fillonce and two other mermaids found a tightly-sealed barrel in Mermaid Cove. The mermaids thought that since the barrel is sealed tightly, it must contain treasure or expensive alcohol. Later, Fillonce, Ishilly, and another mermaid, starts opening the barrel, unaware that it was used by the Straw Hats to imprison Caribou.

After Ishilly loosens some of the bolts, Caribou pops out and terrifies the unwitting mermaids. Caribou proceeds to capture the three mermaids with the power of the Numa Numa no Mi as they try to flee and scream for help. Therefore, Fillonce and her two friends become the first victims in Caribous's mermaid kidnapping scheme. The other mermaids at the cove still had no clue that the barrel they found had something to do with Fillonce's disappearance and the citizens of Fishman Island blame the Straw Hats for the kidnappings.

Celebration
After the battle against the New Fishman Pirates has ended, Fillonce and the other kidnapped mermaids were found in the Ryugu Palace. Later that evening, she was seen among the Mermaid Cafe dancers, performing at the banquet held for the Straw Hat Pirates.
