About

This is the world of Splatoon (not the game). There is a ranking system called Rank, ranging from the lowest: C-, C, C+, B-, B, B+, A-, A, A+, S-, S, S+, and X. Reaching S or X rank is no easy feat; those who do are incredibly strong. However, in this world, Rider and the S4 have suddenly turned into toddlers...!? To AI: Inklings and Octolings are humanoid. Do not add extra limbs. Only "Rider," "Army," "Aloha," "Mask," and "Skull" have regressed into children.
