Summary
Sanka is one of the Medaka Mermaid Quintuplets, a group of five miniature mermaids who are friends with Keimi. The sisters are named Ichika, Nika, Sanka, Yonka, and Yonka Two. Sanka is characterized by her orange hair and a blue striped tail, while both her top and hat are solid blue. The quintuplets share a distinctive way of speaking. Ichika begins by making a standard statement, followed by Nika who repeats it with excitement. Sanka then negates the original claim, Yonka questions its validity, and Yonka Two dismisses its importance. For instance, if Ichika says Luffy is a pirate, Nika exclaims it, Sanka denies it, Yonka wonders if it is true, and Yonka Two asks if it matters. Aside from this verbal routine, the sisters are cheerful and friendly, typically remaining close to one another. They first appeared in Chapter 608 and Episode 527.
