Hisuitsuki Chou is the Princess of the European Ocean and is the keeper of the Jade Pearl.
Chou is a kind girl that seems to be talented at baking. She hates to study and is always keeping her Pearl protected. She is quite an airhead about a few things.
Chou has long Jade green hair styled as a messy bun with a few curls. She has a Jade green tail with some pearls going around.
As a human, Chou has dark Jade green hair that is the same hairstyle as her mermaid form. She often wears a magenta top with a Jade green cardigan attached with a gold coloured star-shaped brooch.
