Rinko is an ordinary girl who has a lot of dreams in her life. She shows a bit of shyness towards others but sometimes left out, thought she resolves them later on. Rinko also shows a lot of tendencies towards her fears, sometimes overcoming her arcrophobia when she tries to convince Garnet or being determined to take all the risks, even if she untended wanted to be more confident using Ruby's failed magic. She also has a good sense of Justice, usually wanting to protect others and shown to take action for the sake of her friends and getting all the lost Jewelpets back to Jewel Land, no matter the risk. Usually, after she obtains the Jewel Stick, she starts to gain confidence thought using the said item would take her a while to get used to.
