Ruby is the shortest of the rebel cast but comes in a fiery package, Their nickname is inspired by the tuft of hair sticking from their head like a candlewick. They are naturally competitive however are sweet towards their friends, often trying to pick up new things but tending to take a few times to get it right.
Ruby looks up to Rose as their personal idol after she taught them to value themselves more and now hopes they'll be able to live confidently like she does

Speaking style; Ruby sounds fairly like the regular rubies seen in the show.
