Kodama (小玉) is an anime only character in the Post-Alabasta Arc. She is a great fireworks expert and also makes them. She lives on Fireworks Island with her grandfather, Odama, whom she helps as best she can.

Her parents are dead due to the malfunction of a firework named Ball 205 during the festival from the year before. This year, she planned to release the Ball 205 at nightfall, hoping to accomplish her parents' dream. Usopp managed to help her make that dream come true.

The word "kodama" can also mean "echo" in Japanese
