Uh-huh! That's right! We're sphere hunters.
The Kinderguardians are later granted with various items, but no spheres. The Gullwings continue deeper, and exploited Isaaru's plan to make Zanarkand Ruins into a tourist attraction. In Chapter 2, should the sphere containing Vegnagun's records be given to New Yevon, the Kinderguardians will grant players the Cat's Bell accessory in Bevelle. In Chapter 3, they also give the Blood of the Beast Garment Grid if met in the Bevelle Underground.
In Chapter 5, the Kinderguardians are located at the entrance to a labyrinth dungeon in Bevelle, Via Infinito. The trio does not enter the dungeon, instead, they would stand near a Save point, watching the Gullwings progress through the dungeon. By the end of the game, there seems to be dozens of members and are said to have become something like a kindercorps by Maroda.
The name Kinderguardians refers to the German word "Kindergarten", meaning "playground for kids", referring to the fact that all of the Kinderguardians' members are children. It also references Pacce's previous role as a guardian to his brother.
The names of two of the Kinderguardians, Hana and Taro (generic Japanese girl and boy names meaning "flower" and "peach"), refer to their small role in the plot — in Japanese, the names Hana and Taro Yamada are the rough equivalents of Jane and John Doe.
