Born and orphaned along with Darry in Adai Village, Gimmy and Darry also both drew straws that would force them to be expelled from the village when the population became too large, and Rossiu joined them as they were effectively adopted by the Gurren-dan. They were small children at that point, but as they grew older and became teenagers they joined the Grapearl Army of Kamina City. They also both took part in the final battle against the Anti-Spiral.
Personality
