Summary
The Medaka Mermaid Quintuplets are a group of five diminutive mermaids who share a friendship with Keimi. The sisters are identified as Ichika, Nika, Sanka, Yonka, and Yonka Two. Yonka is distinguished by her pink hair, a tail striped with brown, a brown top, and a white hat. The quintuplets communicate using a distinctive, synchronized speech pattern. Ichika begins by making a standard declarative statement. Nika follows by repeating that same statement as an exclamation. Sanka then asserts the opposite of the original claim. Yonka questions the validity of the initial statement, and Yonka Two concludes the routine by questioning whether the statement is even relevant. For instance, if Ichka states that Luffy is a pirate, Nika exclaims it, Sanka denies it, Yonka wonders if he might be, and Yonka Two asks if it matters. Aside from their unique dialogue style, the sisters are cheerful and friendly, and they typically remain in close proximity to one another. They first appeared in Chapter 608 and Episode 527.
