Geki Kuroiwa

The ground warrior. Geki has a rivalry with En, who injured his arm in a fight at Geki's old school. He is even more short tempered and impatient than En and has a serious crush on Maria. Geki had something of a misguided view on being a hero at first, but eventually became a valuable member of the group. His robot, Dag Drill combines with Kai's, Shin's and Yoku's.
