They were officially going to be twins. However, twins doesn't ness mean "brother and sister". They were conceived as androids. Ergo, one could argue "twin" means "two" or "matching" in this case.

regardless the matter is moot since they don't have canon storylines. I find it worthless arguing over what the relationship is. It wouldn't matter if they were mentioned, how many times do producers cover Merli and Lapis being Fairies? While certain Vocaloids do have canon concepts and bios, you don't have to acknowledge them.
