Daichi Sumeragi is the youngest on Tyson's Beyblading Team as introduced in season three. He has inherited Strata-Dragoon from his late father.
Tyson's favorite pet name for this kid is "monkey boy" due to him having growing up in the wild and the outdoors.
Where Daichi came from, there were no Beystadium dishes, so he made do via the woods, the plains, the rocks, hills, etc.
