For some reason, I just wanted to take on my own challenge after playing Final Fantasy XIII and having a few more ideas. Since Naruto chose Lightning's Path he will use her weapons, summons, abilities and Crystarium.

"So let me get this straight…" Naruto said as he and Lightning are in a Japanese style house in his mind drinking tea. "I am your successor as a L'Cie with a Focus that if I don't finish in a certain amount of time. I would turn into these crystal-zombielike creatures called C'ieth right?" Naruto asked as Lightning nodded her head solemnly still sipping her tea. "That's all believable to me …" Naruto said before developing a small tick mark and throwing into the ceiling "ALONG WITH FLYING PIGS AND THE TOOTH FAIRY!" (A/N: Guess which anime character said that line as well lol) only for Lightning to whack him with a cane out of nowhere.
"To bad runt." Lightning said causing Naruto to glare at her, hey it's not his fault he's still the shortest person in the academy still. "Because this is all real and if you try to run away from the Focus, then you will be a C'ieth in less than an hour unable to fulfill your dream as Hokage." Lightning said waiting for the words to process and saw the look of horror on his face.
"Isn't there some way out of this?" Naruto asked hopefully only for Lightning to shake her head no.
"The only way out of it is to complete the Focus given to you." Lightning said "When you are branded, you were given a vision correct?" she asked as Naruto nodded. "Then that's a clue of your Focus." Lightning said.
"Um, Lightning I have question." Naruto said as she looked at him straight in the eyes "If I fulfill my Focus, what will happen?" Naruto asked causing Lightning to sigh.
"When a L'Cie completes their Focus, they are rewarded by being turned into crystal and gain immortality until they are needed again." Lightning explained as Naruto looked at her with disbelief. "It's true, after all me and the others were turned into crystal after we saved Cocoon from destruction." Lightning said causing Naruto to go wide-eyed and she answered his unasked question. "Yes, I and my friends saved the world when it was still there and due to that we became famous heroes after the destruction of the Fal'Cie. But somehow Anima survived and was waiting for something which I went to investigate with the others. Somehow we were sealed away in our weapons and after someone picked one of them up, our conscious appeared inside them trying to train them to live up to our expectations. Sadly all of them turned into C'ieth and are now currently wandering these ruins acting as security guards doomed to forever haunt the hallways." Lightning said as Naruto gulped nervously.
"Hmmm…" Naruto said, thinking of his vision and made out some clues. "Let's see here, the creature I saw in my vision had 10 tails, one giant eye similar to the Sharingan, and had foul chakra that life near it were dying like it was some kind of poison. Maybe Kyuubi has some clues, I'll try and ask the plushie when I get the chance." Naruto thought before turning his attention to Lightning.
"We need to get you to the First Arc where I will help you train with my gunblade Naruto." Lightning said only for Naruto to look at her strangely. "What?" Lightning asked.
"I never told you my name so how do you know it?" Naruto asked her with a suspicious look on his face. "It's because somehow I saw your memories of your life when I entered your mind and I was shocked when I first saw them." Lightning said causing Naruto to raise an eyebrow. "You were hated by people because they couldn't tell the difference between you and the fox and you still looked on the bright side even when you were down and never gave up, their hatred was similar back when Cocoon feared me and my friends when we were made Pulse L'Cie but we proved them that we were not monsters and became legends afterwards." She said as Naruto nodded his head.
"So what's your name?" Naruto asked "Because Lightning isn't a person's name, more like an alias to me." He said as Lightning nodded.
"l won't tell you my real name until after you've proven yourself worthy as a L'Cie, but I'm going to train you for your Chunin Exams and give that Neji kid a lesson." Lightning said causing Naruto to grin only for it to disappear when he sensed a menacing aura coming from Lightning "And when you meet this 'Ero-Sennin'," Lightning said "I want you to teach him a lesson about peeking at women!" she shouted causing Naruto to yelp and crawl backwards into the wall in fear. "One more thing, if you ever use that Sexy Jutsu of yours without clothes then I will make you suffer pain that no man has ever seen." Lightning added with a glare that gave Naruto chills up his spine as he nodded fearfully hoping not to invoke her wrath upon him. "Good, now it's time for your basics with a gunblade." Lightning smiled a little too sweetly causing Naruto to sweat nervously.
When Naruto woke up, he had one major headache. "Was that a dream?" Naruto thought before checking his chest to see that the Pulse L'Cie brand was there. "I guess not." Naruto thought bitterly as he got up and picked up the gunblade. "Need to find a way out of here." Naruto said as he got up and looked around for an exit. When he got out of the room, he saw a group of C'ieth there howling in anguish as Naruto looked at them with pity. "Poor things," Naruto said "I need to put them out of their misery." As he took on Lightning's fighting pose as the C'ieth came close. "Naruto, focus and use Libra." Lightning's voice echoed though his mind as he nodded. "Libra!" Naruto shouted as he threw his left arm out like he was casting something and a weird gear-like image appeared on the C'ieth giving Naruto data on his Datalog which he found in a Treasure Sphere before he left the Chamber of Heroes and it revealed it to be a Ghoul C'ieth with many weaknesses. When Naruto was about to attack, Lightning's voice called to him "You are on Commando style, use Paradigm Shift to change to Ravenger." Lightning said in his head which Naruto nodded to. "Paradigm Shift: Ravenger!" Naruto shouted as his red aura turned into a blue one. Lightning then continues to instruct Naruto while watching him from his mind "Now that you are in Ravenger, you can use elemental spells like Thunder to deal electric damage to enemies. Try it out." Lightning said as Naruto followed her instructions. "Thunder!" Naruto said as he threw a barrage of lightning bolts onto the C'ieth effectively killing them. When Naruto was about to leave, he noticed some stuff where the C'ieth once stood and when he got closer, he noticed some of them looked like gems. "What are they?" Naruto asked Lightning as he picked them up. "Spoils from the battle. Keep them with you because they will be useful one day but for now they are nothing at the moment." Lightning said as Naruto put them in a safe place in his ninja pouch.
As Naruto continued his journey through the ruins dispatching a few groups of C'ieth every now and then, he noticed a floating Treasure Sphere at the corner and went over and opened it. Inside it was a different gunblade from the one he was using. The major difference besides the color was the edge of the blade, which looked like it was meant for brute strength and he decided to take it. When he took it, Lightning told him the name of that gunblade was called Gladius and she said that he guessed right for it is more for a physical attack gunblade but she told him not to equip it yet until he was use to her Blazefire Saber gunblade first. When Naruto got to the top of the ruins a few minutes later, his L'Cie mark glowed and caused some of the writings on the floor to glow and open to reveal a ship to come out much to his shock that quickly ended as he entered the ship and followed Lightning's instructions to set it on auto-pilot to the First Arc to begin his training. While the ship was flying out of the ravine and Naruto was relaxing, training mentally with his powers while Lightning unlocked a few more things in his Crystarium letting him use the Water spell as well as a few physical, magical, and stamina enhancing boosts they noticed a spiky white haired man looking at the ship with surprise before it took off to the unknown. "I'll be back Ero-Sennin, just need to take care of a few things." Naruto thought as he continued with his journey that will change the lives of everyone and everything around him.
Well that's it for now people, if any brave L'Cie are willing to take my challenge, please review. Farewell!
