Pearl and Marina are pretty much confirmed to be a couple and whenever I see straight Marina porn I like to think she's cheating on her girlfriend. Never seen anyone do porn of her cucking Pearl though, know any artists who could do something like that? Are you that artist? Do you take requests?

Literally playing splatoon rn. Anyways, since when was it confirmed? I thought it was just fans shipping them together

Confirmed on the official Japanese website

The Splatoon 2 website, or what? If you could link it I'd appreciate it

Marina's description on the Japanese site translates to "Maiden in Love"

That doesn't really mean she's in a relationship, that just means she's in love. More context would be lovely.
