A boy in a blue and white outfit with a topknot raises his hand against a purple background. A girl with her hair in a bun looks to the side against a light green background. A boy in a dark outfit with a topknot holds a staff against a red background. A man in a red and brown outfit with two swords on his back stands with his arms crossed against a yellow background.
