Girarin

Girarin is an anime-only fishman pirate from the Foxy Pirates. He first appeared in the Round-around Roller Race of Davy Back Fight of the anime.

Appearance
Girarin is a purple fishman with yellow-green hair. On his arms are blade-like attachments of sorts which Girarin can somehow expand. While these blades look sharp, they are actually merely for show only. They can however still be used as blunt weapons despite having no edge at all. It is unknown what kind of fishman he is.
