Tama is the best kid character we've had thus far, and is the most refreshing and fun female character of Wano. She led the charge to free Luffy from prison, and subsequently get Udon under control. She has a strong desire to save her country, and actually makes an effort of saving it as one of its warriors. She's a clever metaphor for the current state of Wano. A fragile child neglected proper food and growth, but isn't beyond saving, and has years of prosperity waiting in the back.
Her bond with Luffy, and to a lesser extent Zoro, is very cute and wholesome.
