Yeah, I'm guessing that's the (stupid) logic. The shirt was blue, and that was too close for comfort to the Japanese schoolgirl sailor uniform to them.Wasnt the old default outfit essentially a blue brazier school uniform? Now her default doesnt resemble a school uniform and theyve had no issue since but its hilarious that yeah its the same character just in a different outfit (and she still comes with a school uniform to enjoy in sex scenes haha)
But honestly, it feels more like they felt they needed to demand some kind of change to the game just so they could say that they had made a demand in response to the claim, and that was just the best they could come up with.
