The only comment the artist had for this picture was "The heroines' names are all Kris." So I'm guessing that it's a joke on the fact that Kris was the first playable female protagonist, and the fact that they all subsequently came after her and you can name your character whatever you want...
Wow!What!? You say your name is Kris!?Nice to meet you! I'm the female protagonist for the remake of Gold and Silver...Kris!My name is Kris, too!I'm Kris, too!Me, too! Me, too!What an incredible coincidence!! Looks like we could be real good friends!It was like the night of the kamaitachi
