Squid Sisters

The Squid Sisters (Japanese: シオカラーズ Shiokaraazu) are an idol group in Inkopolis, consisting of Callie and Marie  (アオリ、ホタル Aori and Hotaru). They are also the hostesses for a News Program which announces events, new maps and announces other battle related news. These cousins host Splatfest which is an event where players decide one side to fight for. After battling it out the winning side of Splatfest get a Super Sea Snail.

Callie
Callie's birthmark is on her left side. Unlike her cousin, she wears shorts and seems to have a preference for the color pink. Callie has an edgier design in comparison to her cousin's mellow design.

Marie
Marie's birthmark is on her right side. Marie seemingly likes the color green and wears a skirt rather than shorts. Marie is probably the more timid of the two.

Trivia

 * Callie and Marie's names together are a pun of the word "calamari."
 * The band's name in Japanese is a portmanteau of shiokara (fermented squid stew) and the english word "colors."
 * Their given names in Japanese are derived from real-world species: "Aori-ika" or Bigfin Reef Squid, and "Hotaru-ika" or Firefly Squid.
 * Callie and Marie appear to be the second oldest inklings, (assuming they are twins) the oldest being Cap'n Cuttlefish, however, one can assume many Inklings older than them that don't participate in Turf War are somewhere absent from the game.
 * If you go near the window where Callie and Marie are talking, they will face the player and wave.
