TomierLanely 's character based on Rikamon but not Rikamon.

As they put it "I wanted to have my own version of Rikamon, so here is Iris's cousin Ruki Xiao Yu. ... Ruki is the ungifted one in the whole family, which is her main reason for looking so grumpy. Cheer up ruki, Gil will still give you your fair share."
