Naruto trains Sasuke. Inspired by a one-shot that I read.
Like many kids, Naruto had dreamed of getting a pet. Of course, for Naruto, it was especially more important, as the pet represented a companion. Thus, when he heard Kiba boast during lunch about how his sister was going to be holding a lesson on taking of pets, he decided to attend.
And thus, the moment that the Academy let out, Naruto quickly ran to the Inuzuka compound. When he got there, he found that there were around 30 to 40 civilians- whom all quickly left with mutters of 'That brat is here.' or 'Now my day is ruined.' In the end, nobody was left when Kiba's sister came into the compound.
"Wow, there's nobody at all?! What the hell?!" She exclaimed in surprise.
"Well, they all left." Naruto replied, a bit downtrodden.
"Hmm, yes. Ah, you're that kid that Kiba sometimes talk about, Uzumaki Naruto." She recalled out loud.
"Yup! I'm Uzumaki Naruto, Future Hokage of Konoha!" Naruto yelled and pumped a fist into the air.
"Alright, alright, settle down. Now, I take it you're here for the session?" She asked.
"Well, yeah." Naruto replied sheepishly while rubbing the back of his head and looking around abit embarrassedly.
It was this time that Kiba came home, and Hana had an idea for a prank, involving Kiba and training.
"So, to sum it up, use negative reinforcement by to discourage bad habits, like I used water, while I gave Kiba candy when he learnt from his mistake."
Meanwhile, Naruto just nodded absentmindedly, his mind already on a different topic, namely Sasuke always insulting him.
'Hn.'
'Dobe.'
'Dead-last.'
And inevitably, the two trains of thought came crashing into each other, resulting in, 'I've got! I'll train Sasuke to stop insulting me and to help me train!'
