This game is so great, cuz wdym Luffy and Omni-Man were almost in a gay relationship?

Any reason why I get this error? I'm on Pretendo network, and have Nimble installed. I did everything the Pretendo guide told me to.

Why doesnt Pretendo work for me? I can only use Miiverse, otherwise, it says i can't connect in games.

Imma start Playing Splatoon again using Pretendo. Am I gonna be destroyed by lvl 50 Japanese dudes?
