Riako is a very young girl that have red/pink long hair (but was cut by Sora for no reason and now currently having short hair) with Yellow-Orange red or green eyes color.
Riako, not often serious, is an airheaded, laid-back and clumsy captain. She may also appear to be idiotic, violent, vulgar, hyper, short tempered and can be really scary at sometimes. When in a good mood, she is sweet and caring. She also likes to pop out out of nowhere and will keep quiet when she doesn't feel like talking.
