Naruto knew that having a voice, that wasn't your own, in your head isn't, exactly, sane. He followed the voice's instructions, but don't get him wrong. He still finds it creepy as all get out. Especially since the voice reads his assignments for him and helps him spell his answers correctly.
"Your dyslexia is terrifying," the voice grumbled. It had become a common saying for the voice. "I don't trust Misuki. He seems like the other adults in this village."
   'I know,' Naruto rolled his robin's egg eyes. 'You tell me at least once a day.' The voice boomed in laughter as they watched Naruto's classmates sort of fail the new technique Iruka had just shown them. 'Uhg. I'm going to fail this one also. It's all based on chakra control. I don't have that!'
"Don't worry," the voice smirked. "I know what to do. Here," after explaining his idea/imparting his knowledge. The blonde felt like face palming. Now to find the correct chakra power to give this newest technique.
   He failed. Miserably. Even Kiba the next person in line for last place, despite Shikamaru being in that place on paper, got it sort of correct. It only frustrated the blonde more with that knowledge. He did it correctly. Even the voice said he did. Heck. Even Iruka said he had everything correct.
   'What happened? Did I over power it?' The voice seemed to contemplate what the pre-teen said. 'What?'
   "I said pay attention Natuto," Iruka snapped. The cobalt eyes focus on the teacher. "As I was saying,"
   'I spoke out loud didn't I.'
   "Yes," the voice sighed. "I have another idea. It will have to wait till later. And the old man will need to be involved and notified of things."
