The Medaka Mermaid Quintuplets
A group of five tiny mermaids who hang out with Keimi. They're known as Ichika, Nika, Sanka, Yonka, and Yonka Two—basically best friends who are almost always together.
The quintuples have a pretty distinctive way of talking that fans find entertaining. They've got this whole routine where each sister riffs on what the first one says. Ichika makes a statement, Nika repeats it excitedly, Sanka contradicts it, Yonka hedges it with doubt, and Yonka Two basically asks why it matters. It's quirky and repetitive in a charming way.
As for looks, Yonka Two stands out with dark brown hair and a yellow-striped tail, plus a black top and a jaguar-print hat.
Beyond their signature speech pattern, they're cheerful and easygoing—the kind of characters who seem genuinely happy to be around each other.
