Firestorm Shinobi

Kentaro: Let's find out which power is stronger?


Ray(In head): I can see him slowly moving. Maybe the sharingan gives increased reaction time. Why is it so blurry?


Kentaro dodges the fireball, and when he moves ray comes down on him with a punch that slams Kentaro into the ground. They both do a backflip, and they land 15 feet away from each other.


Ray's body starts to feel a lot of pain.


Kentaro: Don't you know anything about the sharingan. You've just unlocked it, and it gives you a faster reaction time. Your body isn't used to that. Your reaction time is so quick it puts extreme strain on your body. You're done. 


Renjiro knocks him out with one good punch.
