Seeing Kakashi laugh this heartily surprised Hiruzen, who took down his smoking pipe on table, glanced over at Kakashi with a curious gaze. Danzō's gaze also turned a little curious at Kakashi, which he immediately turned back to his usual, as fast as it appeared.
This was indeed shocking them, they after all never seen Kakashi laughing like that. Kakashi then paused, glanced straight at Hiruzen, asked, "So, what's your decision, Sandaime-sama? Have you agreed?"
Danzō then also stared at Hiruzen, expecting him to agree, and let Root and Anbu once again monitor Naruto 24/7. Hiruzen noticed both of their stares, and sighed heavily. "For sometime, we should have Anbu around your Team..."
"I Refuse."
Kakashi immediately interjected plainly and directly refusing Hiruzen. He had always defended Hiruzen in his mind, believing that Hiruzen didn't do what happened to Naruto purposefully till now, blaming completely on Danzō.
But he started to believe that Hiruzen might also be as blamed as Danzō in Naruto's mistreatment in Konoha till now. Kakashi couldn't feel that Hiruzen was showing worry in his tone for Naruto, rather felt that Hiruzen also didn't want anything to happen to Kurama, the Nine-Tails, Naruto wasn't his concern here.
Hearing Kakashi's plain refusal, Danzō and Hiruzen paused, staring at Kakashi in bewilderment. Danzō barked, "Are you repudiating Hokage? Betraying Konoha?"
"I only said what is right, and you shouldn't be the one to talk about betrayal to Konoha, Danzō-sama." Kakashi simply stated, staring at Danzō's left visible eye with his right visible eye, both hiding Mangekyō in their respective covered eyes.
"WHAT—"
Danzō frowned, once again about to bark but Hiruzen suddenly exuded a powerful aura, which, actually didn't intimidate any of those two. Danzō didn't even take Hiruzen seriously anymore, considering him a soft person, a dog who only can bark.
While Kakashi had his confidence sky-rocketed, from seeing his Chakra increasing at a tremendous pace each day. Now his chakra could be said to be behind mostly only Tailed Beasts, he believed that his strength also had increased considerably, more reason for him to not take such an aura seriously.
Plus, now even the little bit of respect he had for Hiruzen also crumbled down. He once had a thought of saving Hiruzen in the future during Konoha Crush, which no longer was in his mind.
But still both, Danzō and Kakashi completely went silent, looking at Hiruzen, who frowned, his brow furrowed at Kakashi, he also didn't like the fact that Kakashi refused him in such a blunt way, more so, even cut in when he was speaking.
"Kakashi, I didn't doubt your abilities," Hiruzen began speaking again, "But you should know that even this current peace is just a facade, we need to take precautions, Kyūbi is important for the village, and you also wouldn't like anything to happen to Naruto."
"I agree, Sandaime-sama." Kakashi said, "However, I still refuse to have Root following my Team everywhere."
He clapped loudly with his both hands, and his shadow clones took those Root ninja into the Hokage's office, threw them at Danzō's feet, and dispersed. "I assure you Sandaime-sama, as long as I am with Naruto and others, nothing will happen to them."
Hiruzen sighed again, taking his smoking pipe, closed his eyes, contemplating what to do. Danzō however got furious, seeing that Kakashi throwing his Root ninja like rag dolls, clearly felt disrespected.
He barked again, "KAKASHI! WHAT'S THE MEANING OF THIS? YOU—"
Hiruzen once again interrupted Danzō, slammed his hand on the table, taking a puff of his smoke, and said, "Alright Kakashi, I trust you, but I hope you remain more vigilant from now on, whenever outside the village with Naruto for missions. You can go now."
Kakashi nodded, slightly bowed and Flickered. Danzō abruptly stood up, slammed his cane furiously on the floor, he didn't try to refute Hiruzen, knowing that now he wouldn't change his decision, just glared at Hiruzen with dissatisfaction.
"You'll regret this, Hiruzen!"
Hiruzen settled back in his Hokage chair further, taking another smoke from his smoking pipe, casually looked at Danzō and said, "I am the Hokage, Danzō! I may or may not regret it, but that's my problem to worry about, the Hokage's problem."
Danzō got even more furious, just glared at Hiruzen once more, before rushing out of the office, slamming the door hard behind him. He even left his Root ninja inside the office, didn't give them another glance, which Hiruzen noticed.
He said sharply, "Danzō take your Root out of Hokage's office."
Danzō who had just stepped outside, clenched his left fist at his cane hearing Hiruzen, and muttered, "Once I have my hands on Nine-Tail's, what are you or Kakashi in front of me, I will unify the whole Ninja world."
Danzō didn't answer Hiruzen, just walked forward with cold expressions. He believed that now with having Hashirama's cells, and Uchiha Clan's Sharingan, even Shisui's Mangekyō, the only thing left is Kyūbi.
Once he gets his hand on Naruto, make him his tool, then he will lead Konoha back to its former glory.
However, unbeknownst to him, Kakashi had already made his mind, which he had already planned, but now decided to fasten it, and take out this disease named "Danzō" much earlier.
