While performing on her harp, she is often seen doing a dance that fascinates others and usually leaves them no choice but to watch Rahnai perform in awe.
Rahnai is a very wise and noble female, often seen giving advice and sharing her wisdom with others. She does not entirely enjoy battling, and usually chooses music over it. Rahnai is also very caring towards children, especially her own and her nieces and nephews.
