"It's quite big for a karaoke room… also why is there a bed in the corner?"
"Should I call someone to remove it?"
"No, it's fine. We might need it later."
Hearing Shun and Baccarat's chatter, Mavis' face was turning tomato red.
The only weird thing about the room was that it had a bed and was a bit bigger than usual, but everything else was similar to a normal karaoke room.
There were comfortable sofas arranged in a C shape, and a large screen generated by the help of the ever so hardworking Denden MushI.
The three took their seats. As a professional, Baccarat wouldn't sit and would rather stand behind Shun to be ready for any requests. However, after knowing Shun for two years, she knew what he liked or disliked.
"So… who will go first?"
At Shun's question, Mavis pretended she hadn't heard.
"Baccarat. Break the ice."
"Eh?"
Baccarat didn't remember the last time she had sung. Rather, she had never sung a song in her life. She didn't want to embarrass herself in front of Shun, though it was presumptuous of her, she considers herself very close to him.
So… her brain worked rapidly.
"Ah! I just remembered, Carina has been wanting to meet you for a long time. She's a famous singer, she'd be good to break the ice."
"Really? Then I'll leave it to you." Shun didn't insist she sing, much to her relief.
Baccarat quickly ran out and called Carina, who happily came over to meet Shun and hopefully catch his eye.
"Hello~ I'm Carina."
"Hello~" Mavis matched her greeting, while Shun just nodded.
'I feel like I've seen her before… but I can't remember. Well, if I forgot, then she wasn't important to the story.' With that reasoning, Shun decided to stop thinking.
"Then I'll start," Carina said, and began her signature song.
——
A few moments later,
Carina panted lightly, having put a bit too much effort into her song than usual.
"She really does seem like a professional singer," Shun gave his approval.
"Good work." Shun smiled and then turned to Mavis.
"Well, then. Karaoke set." Shun chanted a weird word to help his imagination, and after some crafting under the shocked eyes of the three as he created things out of thin air,
finally, Shun was able to make a screen and speaker powered by lacrima crystals that could play the music and lyrics he wanted.
"I'll go next," Shun said, once again surprising the three. They thought he just wanted to be entertained, but he was going to sing himself?
Shun smoothly chose his song. Then…
"Sono chi no sadame~"
——
After a few minutes, the most bizarre performance of Shun ended.
"…"
The three were speechless.
"How was it?" Shun asked with his usual smile.
"…It was good, but what were those poses? They were a bit bizarre, I guess?" Mavis replied with an awkward smile.
"Yeah, a bit bizarre," Baccarat added.
Carina didn't know what to say. Her first impression of Shun was getting more bizarre as time passed.
"You guys don't understand… those poses are more important than the lyrics."
"Never mind… who is next?"
"Sorry, but I'll pass today," Baccarat swiftly avoided singing.
"I don't know any song, so I will—"
Before Mavis could try to avoid it, Shun spoke.
"Don't worry, I've already chosen your song."
The song was named Karinui from Hell Girl. It was sung by the same voice actress.
Thinking it would be unfair to pass when even Shun had performed, Mavis stood up and took the mic.
Before long, she started.
"Always a dead end. There is no escape. I place my sorrow upon a bird in the sky. And I'll let it fly. This place is ephemeral. An eternity that binds me~"
"…"
After a bizarre performance, Mavis' song was quite depressing.
'As I always thought, her voice perfectly fits a tragedy.' Shun enjoyed his time in the karaoke room.
——
Soon after, Mavis' song ended.
The three of them clapped politely, appreciating the good singer.
Mavis blushed and took her seat.
"Wow, that was amazing," Baccarat said in her occasional English for some reason.
'Well, it's literally her own song after all,' Shun thought, then gave her a thumbs up.
"Thank you…" Mavis replied. Even she hadn't known she would be able to sing this well, especially since it was a song she had never heard before.
Like that, the four of them spent the next two hours singing and having fun. Baccarat joined in, and 'luckily' for herself, she was able to sing better than she expected.
——
Baccarat and Carina just finished a duet together. Since they didn't know the lyrics from the songs that Shun had added to his self-made karaoke set, they were facing the screen, turning their backs to Mavis and Shun who were still seated.
"Ahh, that was fun. Mr. Honorary Admiral wasn't what I expected him to be…" Carina commented while panting, a bit of sweat forming on her face.
"Yeah, his words and actions don't match. He's very kind…"
However, reality was often shocking. After their performance, where they had put their heart and soul, their audience wasn't paying any attention to them.
When they turned back… the two friends they had shared a karaoke night with were in their own worlds.
"Mmph~"
With occasional 'accidental' touches from Shun, Mavis' switch had been slowly turning on.
Currently, Mavis was straddling Shun's lap while kissing him.
"…"
Baccarat and Carina didn't know what to say or do.
Baccarat thought they should leave the room for them, but Carina thought otherwise.
"…Should we join them?"
"Huh?"
It wasn't a secret that wealthy and powerful individuals were perverts, so Carina wondered,
'Was he expecting us to join them?'
Neither of them was the type to settle with a man, but with the world's strongest man… it was worth it.
'Also, he's handsome too…'
That was Carina's thought process that led to her suggestion.
'What are those two perverts talking about?'
Shun, of course, didn't miss their little conversation.
Looking at Carina and Baccarat's figures and beauty, honestly Shun wouldn't mind them joining, but not this time.
"Baccarat, sorry, but let's continue the party later. I have something important to do now." Shun spoke without shame as he patted Mavis' back.
Creaak—!
"Y-Yes…" Baccarat and Carina left, feeling flustered thanks to Carina's suggestion.
Now, there was nothing else that would stop them.
As soon as they heard the door close, they continued what they were doing. They had an important mission: to breed and help their weak continent with strong mages.
——
Two hours later…
Since Mavis didn't have the physical strength of the people of the One Piece world, Shun had to stop for today.
"You… seriously did it on purpose, right?" Mavis asked, trying to sound angry while nestling into his chest, which wasn't very convincing.
"No, it really became a reflex of mine to use contraception magic."
Shun didn't even have to create the magic, since the Fairy Tail world already had it. Shun had been using it every time for the past few years.
Because Shun kept using it 'accidentally,' they had to keep going at it more and more.
"…"
Mavis used her right to remain silent. People familiar with Shun knew that arguing with him was pointless.
"Should we go back?"
"Already?"
"I forgot to tell you, but the time difference between the two worlds is 4 to 1. Since we spent half a day here, about two days should have passed in our world."
"What?!" Mavis, who was tired and sleepy, suddenly sat up.
'Disappearing for two days together… it'll start some rumors. Or it might have already spread.' Mavis had a headache.
Mavis stood up and performed a reverse stripping performance.
Once she was fully clothed, Shun didn't waste time and teleported the two of them back.
The reason Shun brought up going back was this:
'My instincts are telling me something fun is waiting.'
——
The two of them arrived right before the entrance of the Fairy Tail guild. The paw-shaped bubble dropped them, leaving a smooth paw-printed crater on the ground, which Shun used Arc of Time to fix.
"Phew, we're home."
"Mm," Mavis nodded and, without realizing it, had clasped Shun's hand.
However, Shun's words brought her back.
"Why is there no one in the guild?" Shun said and used his sensory magic and Haki combined.
"They're all at the port… and something huge is approaching."
'What just happened in the two days we were gone? It's also about to start a giant cannon attack to shoot the entire Magnolia in ten seconds.'
"There's no time to explain. I'll repel the attack first."
"Eh?"
Shun sighed and used Makarov's giantification magic.
Shun grew to the size of an average giant from the One Piece world. However…
'Learning giantification magic was essential since my paws can't repel attacks that have too large an area of effect. But… not enough… more, more times ten… twenty…'
Shun now stood at 117 meters in height, which immediately drew the attention of everyone. Anyone in Magnolia town could now see Shun.
"Aghh—! What the fuck is that?"
"Honey, language!"
"Sorry, mom…"
With his size growing to unprecedented heights, even to himself, Shun could now hear all kinds of unnecessary things.
'Despite spending years with many types of Devil Fruits, I wasn't able to awaken any one of them: the fusion fruit from Bullet, the tremor fruit from Whitebeard, and this more more fruit from Byrnndi World. Maybe only one Devil Fruit can be awakened by a person. The other reason would be that my mind isn't able to keep up with the fruit. To awaken a Devil Fruit, the user's body and mind have to be able to catch up to the fruit. My body is at its peak condition. I've grown stronger, but my mind hasn't gotten any stronger. Instead, it's even gotten weaker. How do I even strengthen my damn mind?' Shun shook his head and stopped the spiral of unnecessary thoughts.
'It's a really bizarre feeling… it's too much information… no wonder giants are often idiots.' While lightly roasting the entire race of giants, Shun focused his eyes on the approaching huge island-like entity. It was about to shoot a cannon huge enough to obliterate the entire town of Magnolia.
'Its appearance is similar to the robots from The Incredibles animation, with many legs supporting it to move across the seas. But this one is hundreds of times bigger.'
Shun cast paw bubbles on his legs so he wouldn't have to walk and crush the civilians to death. He walked on air, and in just a few steps he was able to reach the port, where every member of Fairy Tail was discussing how to deal with the situation.
"W-What is happening?!"
"Who is that?"
"It's our guild master!"
All kinds of panicked noises were heard from the members of the Fairy Tail guild.
"S-Shun? Were you always this big?"
"…"
Natsu's question calmed everyone down effectively.
"What kind of messy situation is this?" Shun asked, but there was no time for them to answer.
WROOOM—!
A magic attack made of all kinds of dark colors was shot toward Magnolia.
Shun simply took his stance to repel it toward the sky. After all, he was interested in what the deal was with the island-like thing that was attacking them.
Just as the attack was about to meet Shun's paw, a red-headed figure shouted toward Shun.
'Is that Erik? What is he shouting? Ana…?'
With Shun still unfamiliar with his giant form, he couldn't focus on only Erik's voice.
Cobra, aka Erik, hadn't become the poison dragon slayer in this timeline. He had become a sound magic user.
At this moment, he was desperately trying to tell Shun not to meet the attack.
"NIRVANA!!"
——
Just a bit earlier…
After days of searching, Erik's team, aka Oración Seis, and the alliance of the Fiore guilds were able to effortlessly beat the dark guild led by Erigor.
However, like in the original timeline, Nirvana was activated. But Erigor didn't care about the creators of Nirvana. His plan was simple: use Nirvana on the so-called strongest mage, and the light guilds that he hated would be destroyed. He was a man of quality over quantity.
"Damn it, this thing isn't stopping. Are you sure you bastards are destroying it at the same time?"
"Of course," Richard said.
"Indeed," Jura said.
"Yes," Lyon said.
"Mm," Macbeth said.
"M-Men."
"…"
"Fuck, we shouldn't have trusted that ugly bastard to do his part. We got fooled by his voice!" Erik, aka Cobra, was furious.
The Oración Seis team were on par with Natsu's team, or even better, with a mission completion rate at one hundred percent. Though they didn't say it openly, they felt proud of being the only team handpicked by Shun. But they were about to screw up, and it was going to be the biggest mess the Fairy Tail guild, or perhaps the magic world, was about to face.
Everything was going perfectly. The dark guild wasn't even a threat. Their team alone could have completed the mission without the alliance. Unfortunately, there was an imposter among them who had failed to match the timing. The trick to stopping Nirvana, which was a giant ancient magic in the shape of an island, was to destroy its six magic lacrima cores at the same time.
Destroying them at the same time was hard, but with the help of Blue Pegasus' Hibiki's Archive Magic, it was relatively easier… however, reality was often disappointing.
When it failed, the lacrimas would be restored back to normal. Before they could retry, Nirvana had already reached Magnolia port and had blasted its attack toward the entire town of Magnolia.
——
Back to the current time.
For the first time in his life, Shun was witnessing a weird sight.
'This magic blast isn't being repelled. Instead, all of it was being absorbed…'
Also, for the first time in a long time,
'I'm feeling dizzy…'
"Shun!!"
To the shock of fairy tail members, Shun had become completely immobile in his super giant form. His giant stature completely froze in place, his body still supported by his paw bubbles so as not to crush the civilians.
Just like how Shun never doubted his paws to repel magic, the members of Fairy Tail were in shock.
"…"
——
"What happened to me…" Shun woke up in an all-white place. After a bit of walking, he found a sofa and a table. In front of him was a big screen.
"Now I remember… that thing is called Nirvana, an ancient weapon that changes people's light and darkness. Psychological types of attacks wouldn't work on people with strong Conqueror's Haki, and more importantly, why didn't my paws repel it?"
Shun had so many questions.
Currently on the screen was playing the scene of the ancient weapon Nirvana being shut down and beginning to crumble in the distance, far away from Magnolia port.
Shun took a seat on the sofa and waited for an explanation.
"Oh? Gildarts and Laxus are here today? Except for the Phantom members who haven't officially joined, like Ur, Ultear, and Mystogan who is currently in Edolas, everyone else is here today…"
"Is this the place where the system or whatever thing watches me…?"
"You're almost right."
"Huh?"
When Shun turned to the direction the voice was coming from, to his surprise, a figure that had exactly the same face as him was standing there.
Step. Step.
"Heave-ho…" With some questionable noises, the figure sat down on the sofa, facing Shun.
The figure was similar but was skinnier, shorter, had black hair, and lastly, a dumb smile on his face.
"…"
"Is this Nirvana's doing?"
"What do you mean?"
"Like… you're my light version and we have to fight, and the winner becomes the real me? That trope…" Shun asked with a tired expression.
"No… I don't know how you… never mind, I can guess how you misunderstood that. I'll explain everything."
"Thanks."
'Surprisingly a reasonable guy,' Shun thought with a small smile, but the other's next words were ridiculous.
"I'm the real owner of the body you've been using."
"…"
Seeing the white-haired Shun (W-Shun in short) speechless, the black-haired one (B-Shun in short) continued.
"Hmm, the system thing… that showed you your past life before being sent here. He was wrong."
"…"
"In short, you are indeed reincarnated into the Fairy Tail world, but the Mushoku Tensei world memories aren't yours. They're mine."
"Ha…?"
"To put it in the simplest terms, that system thing is an idiot. When I sent myself to Tenroujima after being severely injured, my soul was in a deep sleep due to overusing powers beyond my ability, like traveling to a different world. But that system guy misunderstood that he was doing a good deed and placed your soul into my body."
[It's not my fault… you guys both had strong souls and were gifted in fighting. All souls mostly look alike to me…]
The system bastard that had been silent for almost a decade finally spoke, but the words it said were poorly made excuses.
"…I have no idea what you guys are talking about…"
Ignoring W-Shun, who was still confused by the whole talk, B-Shun continued.
"If this guy hadn't put your soul in my body, you would have normally reincarnated as another person in the Fairy Tail world."
"…"
"This guy went completely silent around a decade ago, right? Around that time, I woke up and tried to take my body… however…"
"I had already possessed it, and you couldn't?"
"Yes, but I could have taken it back anytime I wanted. Since it's my body after all."
A bunch of ridiculous claims came one after another at Shun.
"Then why didn't you take it?" W-Shun asked.
"You see… one body can contain only one soul. If I took control, you would disappear."
"Huh? If that's the case, how are you still here?"
Though it was hard to believe, W-Shun decided to keep the conversation going.
"Probably because I'm the real owner. But I can tell I can no longer remain here. My time has come…" B-Shun spoke of his death nearing but still had the foolish smile that radiated kindness on his face.
After a long silence,
"…So, you wanted your body before you disappear, huh…"
W-Shun found it ridiculous and was ready to fight, if he could even fight in this weird space. But once again, he was told ridiculous words.
"No. Like I said, if I took over my body now, you would disappear. If that happens… what about your friends and lovers…"
"Huh?"
At this moment, hearing the weird sympathy, W-Shun finally began to believe.
'This guy really is the fool from that memory…'
"You're worried that the people around me will be sad?" W-Shun looked at the fool version of himself as if he were looking at a madman.
"…"
The two became silent as they maintained eye contact.
"By the way, the reason you couldn't repel Nirvana was because of me."
"What?" This whole conversation had been confusing Shun from start to finish.
"You didn't know, right? Using the two paws at once absorbs things instead of repelling. It's like when you multiply two negatives, you get a positive." B-Shun started teaching like an experienced veteran.
"If you ever run out of magic, you could use that to aggressively regenerate your magic. Though probably, you will never run out of magic since you got the 'Fairy Heart,' was it?" The fool Shun continued teaching various things that surprised Shun.
"Why are you teaching me?"
"Because my time has come. I won't last another month. Before that, I wanted to meet you."
"Why?" W-Shun asked again. He had lost count of how many times he had asked this.
"I've been watching you. You're living quite a fun life. You're stronger and smarter than me. You should be the one to live."
"…"
"If you were an asshole, I would have taken my body without hesitation. But you're kind."
'Me? Kind?' Shun found the claim laughable.
"I actually planned to disappear without informing you, but… lately you've been having a bit of depression, right?"
Hearing this, W-Shun suddenly understood something, and his face turned red.
"You were depressed when it wasn't even your own memories. So I had to tell you the truth."
"…"
"It was funny to see you like that, if I'm being honest."
'What's with this guy? It feels like I'm talking to a kindhearted grandpa…'
"By the way, my favorite one is Erza Scarlet. The red-haired girl. Why do you never get close to her?" B-Shun asked with feigned frustration.
"Her strict personality… She reminds me of my wife." B-Shun said and closed his eyes as if reminiscing about a dear memory.
"Are you talking about the woman who caused your downfall?"
"…"
"Cough, cough." Pretending he hadn't heard him, B-Shun spoke with a serious face.
"Lastly, don't hold a grudge against the system guy or anyone else. If he didn't put your soul in my body, my body wouldn't have survived anyway. I have no regrets."
"Well then, have a fun life." B-Shun said and stood up and walked closer to W-Shun.
B-Shun raised his right hand toward Shun.
'As expected, he has them, huh…' Shun thought as he saw the familiar paws.
"We will never meet again."
POP-!
——
Back to the real world.
W-Shun woke up in his giant body without any issue.
"…"
"Shun! Are you okay?" A bunch of concerned questions were thrown at Shun, but Shun wasn't in the right mind to pay attention to them.
'So… because of this system bastard, for almost a decade I felt depressed, but it wasn't even my own memories?'
"I thought my life was a tragedy… but it was a comedy!"
In the full moon night, Shun in his giant form, under the watch of everyone,
He laughed.
