Here is a summary about this world (not story) :
(I am going to keep this short...)
Basically there was chaos which birthed a goddess( similar to ATG Ancestral God only much weaker...)
She created a son who was massive A.SS perfectionist, he banished his own mother, but he was stupid and ambitious he wanted to rule everything, (even the realm where he banished his own mother, but since he is stupid he needs to find gateway)
So he created his own three kids, one of them looked like his mother so he banished her as well...after creating his kids he used all his power and went to sleep...
The eldest of his sons created a planet, and most of life there, the middle one assisted the eldest one, while the youngest( the banished one) became the goddess of the underworld.
While these two gods are creating stuff to find this gateway they created beings called fal'Cie, since gods were lazy these fal'Cie did everything from controlling ecology to creating food. (massive alive like building, it's weird I know, Fal'Cie come in many shapes and sizes, from giants to ball like things...😑)
After Fal'Cie creation, The two gods retired, since Fal'Cie will do the work for them...
And that's where the story begins of the game...
As Fal'Cie created a USA size floating 'Cacoon paradise' where humans are 'breed'...
Fal'Cie jobs is to breed enough of them so that genocide can be done to open this gateway...
But no plan is perfect as only half of the population went to live in Cacoon(They can't force them IDK why...), the rest continued living in Gran Pulse(The planet)
So Fal'Cie instigated a war between people on Cacoon and people on Gran Pulse...
That failed too...
And that's where the game starts...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~Gran Pulse~~~~~~
High in air above wildness of Gran Pulse White doors appeared and Raynor stepped through them.
First thing in the distance he noticed the massive floating Cacoon, portion of its shell is missing and it possible to see what is inside...
He was pulled by this fantasy-like creation...
Marvelling for second he spread his sense through whole reality...
He instantly found the pesky Gods of this reality...
With single-step, he appeared at the side of sleeping as.shole 'Bhunivelze' The as.shole son of the Goddess...
Raynor pointed his right-hand palm at the sleeping god, it was massive being.
'If this thing really wanted to conserve his power he should have changed his size...what a moron...oh well.'
Raynor focused Destruction and Nothingness laws and this palm right at the sleeping God.
"Hakai..." Moment Raynor said that word the massive Sleeping God started to disintegrate...
*PAINFUL SCREAM*
The massive being opened his eyes and started to scream and thrash around from pain...
"W-WHATS GOING ON!?!" The god screamed in pain as its body started to disintegrate.
"You dying to slow..." Raynor said that as he did three hand seals...
"Tengai Shinsei..." The God realm where these gods real bodies exist started to turn red massive meteorites started to fall down...
They were concentrated on the 'main' God Bhunivelze...
'I should allow Pulse exist... he still needs to 'brand' Lightning and rest so that main story can start...' Raynor focused meteorites at Bhunivelze instead of other sleeping Gods in distance...
He clapped his hands and banished Lindzei, one of Bhunivelze son to nothingness, since he is not such as.shole like Bhunivelze, but Raynor allowed Pulse the other Bhunivelze, son to exist instead he put him under his mind control...
After doing so Raynor can enjoy this world with these pesky gods now 'under control'.
***BOOM***BOOM***BOOM***
"So that's how it looks like when meteorite smashes into a God..." Raynor pulled his phone and took a few pictures...
He then created a new folder which was named 'Final Fantasy XIII' it's where he stored these pictures.
"Not bad..." After saving them there, he pulled out his notebook, and put a tag on 'dealing with Pesky Gods'
"Next, going to Cacoon..." looking a dying main villain of whole XIII franchise Raynor was quite satisfied while he didn't play other two games (XIII-2 and Lightning Returns) he won't need too as this pesky God is dead...
After seeing it vanishing to nothingness Raynor took a step and appeared in this original position where he entered into the world.
He took another Picture of the Cacoon.
Focusing on the 'Paradise' in the sky he started scanning the whole thing finding the seaside city of Bodhum...
'Ho... what a tropical paradise...' he took a step and appeared in the City of Bodhum... he quickly turned invisible and changed the clothes to fit with the place...
A Hawaiian palm tree shirt, white shorts and flip flops, with nice futuristic-looking sunglasses, since he is in the world which is in somewhat like 23 or 24 century...
As Raynor already noticed holograms, fancy-looking cars which runs on god knows what power source...
'Probably something fal'Cie produce for them...'
Raynor started to walk around exploring, the same time he started to look for two special ladies, since they are human and don't have any unique powers yet, he needs to look in somewhat old fashion way...
He did cross seal with his hands...
With *POP* several copies of him popped into existence...
They all nodded at each other and went to look for a pair of pink heads...
While the original went to look for a smart-looking person...
Once he found someone to his standards he put his hand on him, and skimmed through his head, skipping his personal life, instead of looking for information on languages, mannerisms, general knowledge of the world...
Once he got what wanted he created some money for him and added to his wallet...
'This world is interesting, people speak English... yet everything is written in this weird language which they call English as well...is this because my game copy is in English?'
Thinking for a moment he continued his exploration, he looked at the building, the holograms, cars, how people are dressed, seeing so many of them have different hair colours, it's something else...
Much different from ATG, it doesn't have that mysterious ancient feel to it, instead it's more colourful? and fantasy-like...
The best part the are no young masters or greedy Sects... only pile of xenophobes...
Once shit hits the fans that there are 'people' from the lower world...
Well then the whole Utopia setting crumbles down...Panic kicks in... fal'Cie really knows how to create those kinds of things who would suspect their 'caretakers' to be evil?
Raynor never saw such massive xenophobes anywhere else...
Eventually he founded what he was looking for, as one of his shadow clones just popped.
He processed his memories in nanosecond...
With single-step, he appeared on one of the highest buildings he looked at the side toward Lightning house.
He whistled seeing that.
'That one hell unique house!'
He scanned for any life forms...he smirked what he saw...Serah was home, he scanned her soul, and found a similar soul in the city...
His gaze went to another soul, and Raynor finally found what is considered one of his first waifu...
Claire Farron or A.K.A Lightning...
'God, she is even prettier in real life several times over, and that no f*ck giving expression...
and those legs...yep it's definitely her...'
Raynor then spends several hours looking at how she went on a mission to wipe off some creatures outside the city...
'She is good with that gun blade, really good... I should probably make one of those weapons for her...'
Raynor then spend several minutes making a weapon which show's the middle finger to laws of physics.
Instead of bullets it shots railgun without recoil, while the blade itself can cut pretty much anything...
'Well, for now, I am keeping you with me, I guess it can be considered 'Ultima blade'...' Raynor chuckled as he stored the weapon, for now, he waited for a right movement to reveal himself to Serah, as Lightning is really hard stone to crack... It would take years... but... there is... of course the main storyline...it will accelerate that, life and death situations tend to do that...
It didn't take long, a few days later while for Raynor it was a few minutes later thanks to Time laws.
He has a chance to reveal himself as Serah was going to shop...
~~~~~~Serah Farron~~~~~~
It was a day of shopping, and the younger of Farron sisters were walking to the shop.
Since her older sister is most of times busy working for Bodrum Guardian Corp, she is the one who does most of the house duties...
As she was walking towards supermarket her mind wandered towards what to cook today... at that moment she missed her step and started falling...
...
...
Instead of falling on the ground face first, someone caught her.
'What strong and firm hands!' She lifted her head and looked at this person, she definitely knew it was a guy because she can see his chest...
She gulped down, internally she wanted to explore that chest with her fingers...
'H-H-How can someone have such a perfect body!!!' She started to blush as she saw his face...
He might have those sunglasses on him, but she was mesmerised by him...
'Is he a model?'
"Are you ok miss?" Hearing his voice, she finally snapped out.
"Y-Yes thank you! I was so into thinking what to cook that I missed a step..." Serah said with a red face.
She can't believe she is so embarrassed in front of someone!
"No worries, it tends to happen..." He said with a smooth voice, he slowly released her from his hands.
Serah didn't even realised he was holding her, she can believe she forgot even about that!
"Umm thanks for catching me! I am Serah! Sarah Farron!, and you are? if it's not much to tell that is?" She said with a somewhat red face, he chuckled hearing that from her.
"It's fine, I am Raynor Valeron!" He gave her his hand for a handshake which Serah accepted really quick.
"Nice to meet you! I haven't seen you around here, are you came here for a holiday?" He smiled at her, which pulled her heartstring, she never felt like that from any guy...
"Yea, and Bodrum is the perfect place for that, and I heard there is that firework festival coming as well..." He said that to her, she quickly nodded at him.
"Yes, it's one of best in whole Cacoon, even can be comparable to Nautilus carnivals!" He nodded in agreement hearing that.
"So where are you going?" He asked her.
"Oh right! Shopping!!!" Serah said with realisation.
She really didn't want to leave him but, she has shopping to do!!!
"Need help? I literally have an empty day, since I am holidays..." He said that to her, as he scratched back of his head.
Serah eyes brightened hearing that she quickly nodded.
"I gladly accept!" She started leading towards the supermarket while slowly starting to ask simple questions.
Like what he likes about the city, is he staying long and so on...
~~~~~~Raynor~~~~~~
Raynor had a massive silly smirk on his face, not only he met Serah but he underestimated his own looks, at this point Serah is a normal girl, and not the world-saving heroine like in XIII-2, while he didn't play he knows the general story of it...
So not only he helped shopping, but Serah offered herself to show the city the next day, as a 'Thank You'.
It means he got her phone number, by this point Raynor used his powers on his phone to make it universal...
Meaning it works on this world as well...
So it's not a big deal.
Funny enough he realised that it was a moment for Serah to actually meet her original Fiance Snow at this moment, but Raynor used very powerful compulsion on him to go home and work on his Bike...
Thus they never met, Raynor didn't actually like the guy as he was in his early twenties, yet he was acting like Naruto in his early days...
A Guy with Hero complex...
'So I think I did a favour to Serah...'
Raynor looked at his Phone and already saw a message from Serah as she was complaining something about food...
Raynor smirked...
There is at least a month or so until the start of the main story.
'Let's have some fun...'
Teenager>>>Otaku>>>God.
To Mc his godhood is a tool to enjoy his hobby...
In his home verse, he will be as 'normal' as possible for a god. (LoL)
That where the whole comedy-realism part comes from, apart from face slapping and Being OP...
Eventually, he will become famous through a somewhat 'normal' means, that is just to troll his classmates that Otaku can be 'famous' and have 'hot girls'
