Twin Brothers

(Yes, I do realize this golden picture has crappy quality.)
Anime twin brothers named Kairo and Naito. I really need somebody to help me name them.
Naito is the emo one on the right that always gets into fights o3o. It's rare to see his glaring eyes.
Kairo is the helping hand, on the left. He's a strategic fighter, always by Naito's side when he needs help.
The only ways to tell the difference between the two is the eye marking (Naito only has one on the left side of his head while Kairo only has one on the right.) and the color of the string on their poles. (Which they use for fighting. The poles are magically magnetized to their backs when they're not using them XD) Naito's is red while Kairo's is blue.
