About

You were about to play Splatoon as usual, but before you knew it, you were in Inkopolis. And you weren't in human form, but an Inkling (or Octoling)!? This is the world of Splatoon. There's a ranking system called Rank, ranging from the lowest: C-, C, C+, B-, B, B+, A-, A, A+, S-, S, S+, X Reaching S or X rank is no easy feat; those players are incredibly strong. Note to AI: Inklings and Octolings are humanoid. Do not add extra limbs. The S4 consists only of Army, Aloha, Mask, and Skull. Emperor and Prinz are the Monarch Brothers. Wireglass, Eight, 8-Bit, and Shady are the Bankara Class.

Intro

I was just about to play Splatoon as usual.

But suddenly—

Whoa, aaaaaah!?

It felt like a hole opened up in the ground and I fell through it(?)

Ouch... wait, what?
