It's just that I haven't screamed in a while.. As you might know.. Luffy screams alot in battles, but I haven't been in many battles lately.*measures the speed with my sight and sees it coming as it pushes me out of the ground as well as sending rocks my way out of the ground as I block them off with my hands* Nicely done. But it shouldnt hurt your throat at all so once more.
*focuses chakra into my chest and my vocal cords*
*Inhales alot of air and screams all I got, focusing a large amount of chakra into my voice, and releasing a thick chakra constantly together with the scream.*
