Also Avery is colored like a Prinny. It really seems like a Disgaea reference.
I'm almost sure it is too, but I don't want to put any information I'm not 100% since these were used for a news article. The Fortune one is also an original palette sort of based on a Touhou character, but I can't remember where I saw that or any more details, so I didn't include it either.
Personally I can see a slight resemblance to a Moku made original...
I salute you for the Kyoko palette.
Mike can pretend all he wants to, but the palette's cyan eyes can't lie.
It was added right after Nu Valentine and Charasoul.
