A fictional idol duo from the Splatoon video game series consisting of two “Inklings” (squids who have evolved to take on human-like shapes) named Callie and Marie (“Aori” and “Hotaru” in Japan). They are voiced by keity.pop and Mari Kikuma, respectively. Despite their name, they’re actually cousins, not sisters.

In the first Splatoon, the duo serve as the hosts for Inkopolis News, an in-universe show that announces game updates, events, and the stages that are currently playable in multiplayer. They also hosted limited-time events known as “Splatfests”, where each sister would represent one of the two teams that would be competing. In Splatoon 2, this role was handed over to another popular in-universe band, Off the Hook.

On top of all of this, Callie and Marie are both members of the New Squidbeak Splatoon, a secret platoon of soldiers organized by Callie’s grandfather, Cap'n Cuttlefish. The two of them have played a major role in the base single-player story modes of every Splatoon game to date.
