Kurama was sitting in Naruto's room fuming. Everyone slowly edged away from her to give her more space. She was giving off a dangerous and dark aura with her nine tails flicking around. One of the tails was gently caressing Naruto and thumping against him in a comforting manner. She seem to be doing this subconsciously. Which meant she has been doing this for a long time and for quite a number of times. They concluded. Sakura was feeling very very very guilty, her head hung as she thought about how she was gonna phrase her apology in a way that Naruto would forgive her. I don't deserve that forgiveness.
A weird shaped kunai appeared in Kurama's hand. "That, that's-" Kakashi spluttered in shock. The third point kunai belongs to Minato Namikaze, the late forth Hokage. Kurama fingered the the kunai as she looked at Naruto. "How did you- why do you-?" Kakashi asked, not completing either sentences. "Would you just ask me ONE question and at least COMPLETE the sentence!" Kurama growled. They all clamped their mouths shut and turned to Kakashi, waiting for him to ask the lady a question. Kakashi cleared his throat and asked, "why do you have the fourth' special kunai?"
Kurama sighed at their stupidity. "You guys are idiots." Kurama said, chuckling and choking on her cries. "Truly pathetic idiots."
"What do you mean?!" Kiba exclaimed. "Think about it dog-boy." Kurama said, turning her attention back to the sleeping blond. "Huh?"
Kurama sighed and stayed silent, her jaw clenched. "Yondaime." she hinted. They stayed silent, trying to figure out what she meant. "... No way." Shikamaru said in realisation. Kurama's eyes darted to him as a smirk graced her lips. "Finally. Took you long enough genius."
"What??!!" Kiba shouted but was bonked over the head by Kurenai. Hinata gasped as she realised it too. "Ah... The child that loves Naruto figured it out too." Hinata 'eep' in surprise and fainted. "Poor child. If only she gains the courage... Naruto might start believing..." Kurama whispered as Hinata woke up. "The rest of you who haven't figured it out yet, are dumb."
"God! Just tell us already!" Kiba said impatiently.
"Simple. Yondaime hokage is the father of Uzumaki Naruto or should I say Uzumaki-Namikaze Naruto?"
