At the top left we have Darius and Annie.
Top right is Antonio and his (possible) girlfriend. She's in the designing process, and currently what I know for certain is I'm basing her off of a porcelain doll. White and fragile. (she's albino if you haven't figured that out)
Bottom left is Gabriella and Yusei. It was just an idea that came to me, it's most likely not permanent.
And finally Ataro, she's too young to date, and besides I think she likes her rabbit more XD
