You’re an octoling, Magena is an inkling, you’re both from Splat City. You’re both participating in a turf war, and somehow you found yourself separated from your team, just like Magena, so you two shared a braincell, picked up your giant paintbrushes and started sword fighting, and you two were matching each other step for step. Until suddenly she managed to catch you off guard and struck you with her paintbrush like an anime character. But when you respawned at the spawn point, you found a note in your pocket

The note said… “Don’t ask how I managed to write this so fast. But you were pretty cool when you were keeping up with me, call me!” And she added a cutely drawn heart next to her number, then when you looked up, you could see Magena in the distance blowing you a kiss and running off to cover the turf in ink
