One evening in a faraway city in another universe...
An inkling named Clauds had just come home from a holiday with her family. She was getting ready for bed when a noise broke her routine.
**RING**
Clauds rushed to the phone and was about to pick it up. However, she stopped short when she saw "Callie" on the LCD.
"I don't care what you have to say to me Callie.", she muttered to herself in annoyance as she began to leave.
Then, the answering machine picked up.
"CLAUDS, IF YOU'RE HOME, PLEASE PICK UP! THIS IS AN EMERGENCY! MARIE HAS BEEN CAPTURED! I REPEAT, MARIE HAS BEEN CAPTURED!!", a voice screeched over the speaker.
Clauds jumped in alarm when she heard what Callie had said. She ran back to the phone and snatched up the handset before Callie hung up.
"WHAT?? MARIE'S BEEN CAPTURED??", Clauds shrieked back over the phone.
"I will explain later. Meet me at the Squidbeak base camp, ASAP.", Callie replied calmly before hanging up.
Without hesitating, Clauds ran back to her bedroom, whipped off her pajamas, put on her Hero Suit and rushed to Inkopolis Square. She slipped through the grate that led to the camp and met Callie, who did not look too good. She had bandages around her head, her left arm was in a sling, and her right leg was on a medical scooter.
"WHAT HAPPENED?"
"We were trying to sneak into Octarian headquarters, but we were caught. He tried to take me again, but Marie intervened and sacrificed herself. I got hurt while escaping. I can't reach anyone else from the Squidbeak Splatoon either."
Callie then proceeded to activate a device that shot a ball of ink into the sky. She told Clauds that she had heard of a group of six friends that always stuck together in another world. She figured that these friends could possibly help them. She also indicated that it had a 50% chance that they would get the message.
