Marie

Your Number agent 7 Callie and Marie in their younger days. Callie and Marie were from Calamari County, where they were born and raised. After they won Inkopolis' first annual Youth Folk-Singing Contest, they moved to Inkopolis where they began their career as announcers for Splatfests and musicians. When first beginning Splatoon's Hero Mode, Cap'n Cuttlefish refers to the player as Agent 3, as they are the third agent of the New Squidbeak Splatoon to fight off the Octarians. He even states that the equipment given to the player is a hand-me-down from the previous two agents. Towards the end of Hero Mode, it is heavily implied that Agents 1 and 2 were in fact Callie and Marie, respectively. Among other clues, Agent 1 almost refers to Agent 2 as "Marie", and the Squid Sisters are seen reporting on the return of the Great Zapfish while pretending not to know how it came back. Marie, like her cousin, has an extremely complicated personality which has grown more complex as the games go on; she is first introduced as generally laid-back, reserved. but also very prone to being sassy and sarcastic, especially to her cousin. Although she cares for her cousin and her music and her fans, she often doesn’t show it and prefers instead to make sassy and sarcastic comments in the first game. This makes her a good foil to Callie, who is more energetic and peppy, with a kind and innocent demeanor.
