Author's note: Okay I'm calling the fourth hokage Yondaime because I can't find his name anywhere, so I'm sorry if it caused any confusion. The technique the 4th hokage uses is mine.
Chapter 4: Explanations
Naruto turned to face his office window; he stared down into the busy streets of Kohona. Even thou the letter explained parts of his missing it didn't explain every thing. Like why he asked a seven year old boy to give this letter to him, how did he know Kakashi Hatake would be his sensei? Too many things didn't add up and made no sense to the current hokage.
"Bring me Kakashi Hatake I need to speak with him." The request barely reached the passing chuunin's ear. With a quick bow he was off, slowly Naruto turned to behind him. The pictures of all the past hokages hung like memories in time. Feeling an all too familiar presence engulf the room Naruto returned his attention to the issue at hand.
"You wished to see me hokage-dono." Kakashi held his head high as the chuunin quietly closed the door.
"I thought I told you before just to call me Naruto, sensei." Kakashi's smile was masquerade beneath his mask. "I have several questions for you regarding the letter the 4th hokage sent me. You're the only one who knows the answers beside the 4th hokage his self and he's been dead for years. Care to explain?" Kakashi titled his head slightly, the fail turned into the most powerful kages the ninja world has ever seen. "Sensei?" Jumping back into reality, Kakashi blinked the blond held his gaze.
"Naruto-sama please understand if this was my plan it would be less complex. The 4th hokage knew you were his child and well forbidden jutsus are more dangerous then people think!" Naruto turned towards his old sensei even more as Kakashi clamped a hand over his covered mouth. Raising Naruto approached the older man.
"Say again." Kakashi shivered as Naruto's darken glare reached his soul.
"It's a forbidden jutsu that let's a human soul see the future without damaging the human vessel or body. The Endurance Soul technique, one limited to your mother's clan. Basically that's the only reason could use it, and the only reason he knew what happened in your life without being there."
"The Endurance Soul technique what happens when someone uses it?" Kakashi gazed the hokage. Barely capable to comprehend what the jutsu could do for a village.
"The jutsu can only be used three times in a person's lifetime unless they're a member of the clan or blessed with the protection of a member. Be blessed doesn't mean anything unless the blessed soul is pure, if not the rules reapply to the soul double what it usually does." Pausing Kakashi waited. "The rules are these: One a person can not use this jutsu for more than three times in their lifetime, unless blessed. Two a person can perform any other jutsu for seven days after use of the Endurance Soul technique. Three for a person to truly understand what they see they must give up a minimum of two years from their lifetime every time they use the Endurance Soul technique. Four the jutsu can be used for the past of the future. Five the jutsu is only for the pure of heart and intension."
"So he used a forbidden jutsu to check up on me during my life." Slipping to the floor, Naruto bowed his head as crystal tears fell from his sky blue eyes. Kakashi watched as the man cried at the love his unknown father had for him. "Is the jutsu hard to learn?"
"No unlike another jutsu this one is really easy to learn. But only the head family of the clan can teach you and Toymo's out of the village, Yzak's in the sand as a Kohona representative and Kiko's pregnant so I'm not risking it." Naruto smiled beneath his tears, raising his head to look at his sensei. "I don't know the Endurance Soul technique! So your siblings are the only ones who can teach you. Can I go my new squad is waiting?"
Naruto frowned at the jounin. "Since when are you on time and since when have you been so concerned with making a good impression with your squad? You probably read porn in front of children!" Rubbing the back of his head in an embarrassed motion Kakashi disappeared within a puff of smoke. Naruto rubbed his face clear of any evidence that he was crying.
'You out did me again old man but be assured that jutsu will be learned. I'll make you proud dad.' Naruto shifted in the direction of the window and stared at the fourth's face craved into the cliff side.
