Team Natsu were in the middle of battling Zeref and the demons of Tartarus and the team was doing extremely well until the ground started shaking.
Natsu shouted, "What the hell is going on now?"
Zeref was in shock, "No...it can't be this power I know it. But why would he awaken now?"
Suddenly a bright golden light filled the area and out of the ground a large golden figure appeared with red eyes being the only visible portion of the figure.
The light spoke with a powerful voice that sunk fear into everyone present. "Zeref to think you have been beaten by these puny wizards. You can't even destroy your own creation how pathetic."
Zeref spoke in a tone no one had ever though he'd use that being fear, "Lord Kronos why have you awakened?"
Natsu said in confusion, "Who the hell is this Kronos guy? I've never heard of him."
Zeref said, "Of course you haven't he is older than even any of the first generation of dragons."
Natsu said, "Well whatever it's just another obstacle in our way." He began to cast Fire Dragon Roar, but Kronos simply waved his hand sent Natsu into a wall. Everyone looked at this Kronos in shock he defeated Natsu in a simple wave of his hand.
Lucy said, "Kronos...I read that name somewhere before." She began thinking when it hit her, "Wait Kronos as in the ancient Titan that nearly destroyed the world, but I thought that was just a legend."
Zeref answered, "No he is very real as is that legend. He is a powerful Titan that almost destroyed the world. But Lord Kronos why awaken now?"
He answered, "I was awaken by this sorry excuse of a battle. You have failed to bring this world to ruin just because of some simple wizards. I granted you some of my power to bring this world to ruin. While I am impressed that you managed to create so many of your demons they were still defeated by these fools. I will give you a second chance, but first these wizard need to be dealt with." He looked at the members of Team Natsu and drew a magic circle and cast, "Eternal seal!" All the members of Team Natsu were suddenly trapped in crystals matching the color of their fairy tail marks. Happy and Carla somehow managed to avoid getting trapped.
Kronos said, "I will give you a second chance Zeref, but first I will tell you this. I would advise to gather help from other dimensions. I will grant you some of my power before I cast the spell. I will rest this world's timeline. Than you and your followers will try again or face my wrath."
Zeref said, "Yes Lord Kronos. I will make sure it happens." Zeref felt magic energy flowing into him from Kronos. Kronos than drew another magic circle and casts, "ETERNAL REVERSION!" A bright light filled the area until it faded to nothing but black.
Meanwhile in the spirit (not celestial) world Mavis of Fairy Tail's spirit sensed a power spell being casts. She eventually learned the spell being cast was Eternal Reversion an extreme version of the Arc of Time only usable by Kronos the Titan. She sensed Team Natsu being sealed away. She needed a plan. Kronos likely reset the timeline to stop Natsu and his friends from keeping the timeline consistent. She needed heros from another realm to make sure things progress as they should. She needed the counter parts of Team Natsu from another world they were the only ones who can save this world. She scanned the worlds and found who she needed.
She said, "Something is strange Lucy and Wendy's ideal counterparts are one person, but to keep the timeline as it should be they cannot be one in the same. They need to be separated, but the only way to do that is with soul splitting magic which is highly dangerous." She paused for a moment and sighed, "I know this is dangerous, but I don't have any other choice. I fear they will be needed in this battle." She summoned the child who would need to be split. Suddenly a boy probably about 18 appeared before her. The boy had short brown hair with green eyes and wore a basic blue t-shirt with khakis.
He said in confusion, "What's going on I was home watching Fairy Tail and now suddenly I'm here?"
Mavis spoke to the boy, "Greetings Hikaru Yanagi. I am sure you are confused, but please stay calm and I will explain everything."
The boy now known as Hikaru turned to her, "W...wait you...you're Mavis! The first guild master of Fairy Tail, but you aren't real. What on Earth is going on?"
Mavis said, "As I said calm down and I will explain." The boy took a deep breath and calmed down.
Mavis smiled, "Thank now Hikaru Earth Land is in grave danger. I need you and your friends help. Team Natsu was sealed away by the great Titan known as Kronos. He is planning to reset the timeline of what you know as Fairy Tail to give Zeref and his followers the upper hand. I need you and your friends to take the place of the members of Team Natsu."
Hikaru said, "I'd like to help, but me and my friends don't know magic."
Mavis said, "I am well aware of that, but once you have taken their place you will learn and have access to their magic."
Hikaru asked, "Is it really that easy? Just boom we know all their magic?"
Mavis shook her head and frowned, "No to keep the timeline consistent you will all learn it just as they did. Essentially you will be living their lives including all the sadness they endured."
Hikaru was silent for a moment, "I see…,but are you sure we are the right people?"
Mavis nodded, "Indeed I am certain of it. So please I beg of you please work with me. If Zeref conquers Earth Land it will not be long until he attacks your home."
Hikaru thought for a moment before stating, "Okay I'll do it. I'm sure my friends will agree as well. So who am I taking the place of?"
Mavis frowned, "Well...you are...a special case. You need to take both Wendy and Lucy's place."
He said in shock, "Wait but how? I'm only a single person!"
She said, "I understand that, but there is way to do it with an ancient magic known as soul splitting magic."
He asked, "Soul Spitting magic what's that?"
She said, "Well it is similar to projection magic. I will split your soul into two, but they can act on their own. You will essentially have another you, but different."
He said, "It has to have its drawbacks though. That is way too convenient."
She sighed, "It does your magic energy will be split between the two bodies. And any major injuries one of you takes the other will have as well even if you are a part."
He asked, "Will I be split in half forever?"
She shook her head, "No I will give you a soul locket once the two halves are put back together you will be one person again though whichever one of you has the most magic energy at the time will become the main body. You two will be able to communicate with each through telepathy and switch places at a moment's notice. I understand this is a big burden, but I don't have another choice."
He said, "I'll do it. I don't want Earth Land to be destroyed if I can do something about it."
She smiled, "Thank you. You already have the heart of a Fairy Tail wizard. I will cast this spell now." She began to chant something in an unknown language. Karu felt himself splitting in two and suddenly there was flash of light and in front of Karu was a girl who looked very similar to Wendy when she was much younger likely how she looked when Grandeena found her. Though she had pink eyes and was wearing an outfit similar to that of Neptune from Hyperdimension Neptunia though less of a hoodie and more of a dress.
She opened her eyes and spoke, "Wow this feels really weird." She had a voice like Nepgear's but younger sounding.
Karu looked at the girl, "So is this really another me? Why is she a girl?"
Mavis said, "It is meant to help make her fit Wendy's role better. Now both of you hold out your hands." The two did so at the same time suddenly a pendant that looked similar to a bird's two wings. "These are your portion of the soul locket. You cannot lose it or you will never be able to unite again." The two nodded in understanding. "One more thing you two are not to tell anyone about your soul being split it would cause chaos if other wizards started trying to learn it. You can't even tell your friends. Am I understood?"
Karu nodded, "Understood so I guess you need a name other me."
She nodded, "Yeah and I think I mean we have one. Gosh this is so weird. How about Aella? It means wind."
Karu said, "Sounds good to me."
Mavis smiled, "Excellent I knew I could trust this task to you. I will contact you as soon as I am able to locate the original members of Team Natsu. I will send you both on your way than. Please take care children." Suddenly the two were blinded by light. Karu found himself in the Heartfillia Manor and Aella found herself with Grandeena. And thus their journey began.
A/N:
