Being able to use all the magic in this world.
Wasn't Kira invincible, then?
"No, I am not invincible since even if I can use most of the magic, it doesn't mean that I have the talent to develop it further, like all of you. The magic that you use is special, and even if we use the same magic, you will be better."
Yes, while Kira could use most of the magic in this world as he could use his hands to reach the core of the magic, the foundation, it didn't mean that he had the mastery to master those magics to the fullest.
Instead, his talent as a mage was mediocre, and even if he could use Giant Magic like Makarov, he was certain that if they fought, he would be the loser, given the significant differences in experience, magic power, and other factors.
Still, his power wasn't limited to Shiro Kotomine, as he possessed the powers of Mata Hari and Henry Jekyll and Hyde.
The power of Mata Hari, despite not being able to be used to fight physically, was helpful in many situations.
As for the power of Jekyll and Hyde, despite its instability, the skill "Monstrous Power" within this servant endowed him with quite good physical ability and endurance, allowing him to fight Natsu head-on with his fists.
So what about his overall situation?
Frankly, Kira wasn't sure, but he was sure that he would be completely erased if he faced the last enemy of Fairy Tail, and to live peacefully in this world was still a long way off, he thought.
Still, regardless, his words made them smile.
"Hehehe..."
"W-Well, it's true that I am strong."
"Strong, you? Did you forget that you were beaten by me yesterday?"
"....."
"YOU BASTARD! LET'S TAKE IT OUTSIDE!"
"THAT'S WHAT I WISH FOR!"
From one fight, it became two, then four, and then most of the guild members fought each other, except for Makarov, who was left with all four, feeling extremely depressed as he knew that Kira had taken the title of the biggest.
Still, Lucy felt a bit helpless, watching everyone fight together, and asked in a whisper to Kira. "Are we still going to join this guild, Kira?"
We.
Unexpectedly, Lucy would use that word to describe the two of them, but this also meant that if Kira didn't join, then she wouldn't join as she would follow him. This surprised him, he thought, yet his answer was obvious. "Let's join."
Of course, he had to join, especially when he saw the increase of the gauge on his gacha.
If he joined another guild or organization or was alone, he was afraid that it would take forever for him to open another gacha.
"Okay."
Hearing that answer, Lucy also agreed and joined Fairy Tail with him.
The guild was weird and probably at the borderline of an illegal guild, but even so, it was still the strongest guild in Fiore and probably one of the strongest in the world.
Makarov might be like that, but his talent for finding talented and powerful magicians was top-notch, as many main characters in this story were adopted and taken care of by him.
Whether it was Natsu, Gray, Erza, Mirajane, or many others, they were all picked up by Makarov, and probably due to that, it used all of his luck, so it made him have to deal with many unlucky events from complaints from the Magic Council or compensation of all the damages caused by the Fairy Tail mages.
With that thought, if in the world of Naruto, the protagonist wished to become Hokage, which was the leader of the village, in this world, even if Kira was given a chance to become the leader of Fairy Tail, he would definitely refuse, especially when he thought about all the compensations, records, and many all the troubles that were cased and by all the mages of this guild.
Somehow, it was understandable why Makarov was bald.
"So, where do you want your tattoo to be, Kira, Lucy? Also, what color would you like it to be?
Mirajane, who had stayed by their side, asked with a smile, inquiring about where they wanted their tattoo to be.
"Just here."
Lucy didn't hesitate, pointed to the front part of their hand, and even asked in a pink color.
"Okay."
Mirajane easily gave the tattoo to Lucy and then looked at Kira. "What about you, Kira?"
Now, what to do?
Kira didn't really want to have a tattoo, but he knew that it was necessary so everyone could be clear that he was a member of Fairy Tail and even registered as people who wouldn't die even if the antagonist made their attack.
So, Kira thought for a moment and said, "Just on my wrist, a black color."
The wrist was quite hidden, so if he didn't want to, no one would see it, but at the same time, it was easy to show as he only needed to pull his sleeve.
"Okay."
As he said so, Mirajane pressed a tattoo stamp on Kira's wrist.
"Congratulations, you two have become members of Fairy Tail!"
Mirajane looked at the two with a happy smile, and everyone joined in, cheering, "Congratulations!"
Having a new member, especially a strong one, was obviously a good thing.
As for Lucy, while they weren't sure how strong she was, she stayed by Kira's side, so her strength shouldn't be bad, right?
Even if her strength was bad, many thought that Lucy was Kira's woman, so everyone accepted her, but many of them knew that Lucy wasn't Kira's girlfriend, so... as a good stock of man came in, it was impossible for those women, who were thirsty for love to let go of a good quality man, right?
Still, before they made their move, they thought to move closer to Lucy to learn more about Kira.
"So, how did you two meet, Lucy?"
With a barrel of alcohol in her hand, Cana asked as she wrapped her hand around Lucy's shoulder, and many others also joined in, waiting for Lucy's answer.
"Well, the truth is..."
Lucy didn't mind telling all of them about her meeting with Kira, and frankly, a little fate might work on their meeting, which made her a little shy, yet even so, she still hid some parts of the fact that she didn't want them to know, especially about his magic that allowed him to crush the entire slave trader group singlehandedly.
Meanwhile, Kira thought about his future plan, which was about how to live from now on. As for how to grow stronger, it was still a single day after he became a member of Fairy Tail, and being impatient would bring him nothing. Still, if there was something he could do, it would be to challenge all the members of Fairy Tail to fight, similar to what he did to Natsu, as his previous fight had filled his gacha for a considerable amount.
'But it hurts...'
Sighing inwardly, he had to say the injuries from his previous fight were still stinging, which made him know that he should strengthen his physical ability further, so looking around, he looked at the member of the Fairy Tail, thinking which magics could help him to grow stronger.
Naturally, it was the Dragon Slayer Magic!
If someone said that, Kira would smack their heads since what made the Dragon Slayer Magic wasn't a Caster-Type Magic, which the user could use without any mediums or tools since to use this magic, one needed to have a connection with a dragon, whether it was to be taught, killed, eaten, or have a Dragon Lacrima (crystallized magic) implanted on their bodies.
Even Natsu, with how he was, had Igneel inside his body, hiding, waiting, and empowered until the last fight.
In other words, even if Kira could access all the magic by using his hands as a key to open the door of all magic, some magics needed a certain tool, medium, or other requirements, which would be impossible to do unless he got that certain tool, medium, or completed those requirements to use.
Yet, even if Kira could use the Dragon Slayer Magic, he somehow lacked confidence in his ability to develop it further, so he knew he should focus on his gacha, as it was the fastest, most stable, and surest way to become stronger.
Still, as he thought to learn the magic of those around him, a commotion happened, which made him turn and see a young boy who faced Makarov.
"Please look for my father! I am worried about him!"
Yet, as the young boy said so, Kira noticed Natsu's expression quickly changed, which made him know that it was his chance to increase the gauge of his gacha.
---
Frankly, I should have made a list of the abilities and skills that Kira received from Mata Hari, Henry Jekyll, and Amakusa Shiro, but while I haven't done that, I will write the detailed abilities of those three characters later.
Rather, it will become two chapters, so look forward to them!
