Raimu

While Beat acts aggressive and impulsive, Rhyme balances him out with her calm demeanor. She is always wearing a smile and is kind to everyone she meets. Always optimistic and reasonable, Rhyme manages to keep everyone organized when she's around. Her young and pure heart is impossible to hate, and gives her great love and loyalty. She has no dreams, except to help Beat. She has an addiction to adages and no shortage of smiles, and without her, the others would be lost.
