Since the 'Ninth Grade Pearl Story' is not well - defined here, the main characters could be a group of ninth - graders. One could be the protagonist who first finds the pearl. Then there might be some antagonists, perhaps a group of bullies who try to take the pearl away. There could also be some supporting characters like the protagonist's parents who have some connection to the pearl's backstory, although this is all just speculation without more information about the story.
As we don't know the exact story, it's possible that the main character is a ninth - grader named, say, Lily. And there could be a best friend, like Lucy, who helps Lily figure out the mystery of the pearl. Maybe there's also an old jeweler in town who has some knowledge about the pearl's origin and helps the characters along the way.
I'm not sure specifically which 'Ninth Grade Pearl Story' you are referring to. There could be many stories with this name. Maybe it's about a pearl that has some special significance to a ninth - grader, like it could be a family heirloom passed down to a ninth - grade student and then something interesting happens related to it.
The main characters in the Pearl Story are Kino, a hard - working fisherman. He is the one who stumbles upon the great pearl. Juana, his wife, is a strong - willed woman. She has her own opinions and is very protective of her family. And then there is Coyotito, their baby son. His life is in danger due to the pearl. The story revolves around these three characters, their hopes and dreams, and how the discovery of the pearl affects their lives. There are also the other villagers who interact with them, but Kino, Juana and Coyotito are the central figures in the story.
Since I don't know the specific 'pearl of the stars story', I can't say who the main characters are.
Since we don't have much information about 'the pearl sad story', it's difficult to say who the main characters are. But it could be a pearl diver who found the pearl, or the person who the pearl was given to.
The main character is Kino. He is a poor pearl diver. His wife, Juana, is also an important character. And their baby, Coyotito.
It's possible that there are some antagonist characters in the Pearl Boy Story. Maybe a greedy merchant who wants to steal the boy's valuable pearls or a jealous rival who tries to undermine the boy's relationship with the sea creatures that help him find pearls. Additionally, there could be a wise old mentor figure who guides the boy in his pearl - related adventures.
