The main reason was that guy was just too tanky.
Rinnegan abilities often aren't in energy forms—like Bansho Ten'in and Shinra Tensei. They are sharp tools against Acnologia, but the consumption is huge and the single-target lethality is quite limited.
No wonder even Zeref only thought about running away once he got "Fairy Heart." Even the guys in the Alvarez Empire were tricked by Zeref.
"Fairy Heart..."
If I were to get Fairy Heart myself...
"Whatever, no point thinking about that. I should focus on training."
Kael sat cross-legged, concentrating fully on practicing Sun Breathing. Sun Breathing, even though it was a technique from a low-power world, had the effect of turning the mundane into something magical.
Besides being able to improve his physical fitness, he found that his magic power could also increase slowly. It was likely that he was absorbing magic particles from the atmosphere, allowing his magic source to grow.
Like an inner strength manual, this discovery had initially brought great surprise to Kael. After all, this was the only way he had found to increase magic power outside of the System.
In the Fairy Tail world, there were similar ways to increase magic power called meditation—using one's skin to feel everything around them and then synchronizing their breathing to mobilize magic power.
Another way was to use magic constantly; this would improve one's casting. After magic power was exhausted and slowly recovered, the upper limit of the magic source would slowly rise.
Every method reached the same goal, but Sun Breathing, compared to the two methods above, was like the difference between a third-rate manual and a peerless martial art.
After all, Sun Breathing improved one's power at every moment. Even though the effect was weak, the increase became very significant over a long period. This was also why he was often able to level up even when the recycled character experience wasn't enough.
Soon, Kael's magic power recovered. Using Sun Breathing made the recovery speed terrifyingly fast, which was another of its great advantages.
While practicing Sun Breathing, Kael also organized the combat skills of each character in his mind.
Every Golden Card was a one-in-a-million master. Every person's combat experience was precious beyond measure.
In the evening, Kael returned to the beach. Everyone in the guild had also finished their day of training. After eating and drinking their fill, they went to soak in the hot springs to relax.
"Kael, how did you get so strong in such a short time?"
Gray asked Kael curiously. They all remembered that when Kael first joined the guild, his magic power was very low. But in the blink of an eye, Kael's magic power was progressing by leaps and bounds.
They hadn't thought much about it before, but now that they were training hard, they also wanted to know the method for rapid improvement.
Kael spread his hands helplessly: "Sorry! I can't help you with that. My magic power increase seems related to how many Heroic Souls I take over. The more I take over, the more my magic power increases."
This was half-true. His magic power did increase more with more character cards, but not through taking them over—it was through recycling them.
"Isn't that just cheating!"
The others couldn't help but widen their eyes. The more takeovers, the higher the magic power; no wonder Kael's magic power increased so fast.
"It's not that simple. Summoning Heroic Souls isn't easy. If you're lucky, you can summon a few powerful ones. If you're unlucky, you might get nothing for several months."
Thinking about how he would get nothing for the next three months, Kael felt a bit helpless.
"That's still pretty freaky!"
"Especially the one where you turn into that giant Nine-Tailed Fox. That was incredible!"
Natsu's eyes shone. Kael's transformation was too strong. Thinking back on it now, his body couldn't help but tremble with excitement.
"You'll become that strong too."
Natsu was the protagonist of the Fairy Tail anime; his strength would become even more powerful in the future.
"Really? Then I'm going to work hard and train!!"
Natsu felt his whole body filled with motivation.
Mage Guild
Lamia Scale
"We can only get second place in the Grand Magic Games every year!! This is too absurd!! It's too ridiculous!!"
"You're all treating this year like any other year, aren't you?! But we won't let that happen again this year!!"
"Lyon!! Jura!! You two are going to participate this time too!!"
The Master of Lamia Scale, Ooba Babasaama, complained while spinning around in circles.
"Fine. I heard Fairy Tail is participating this year too. It's time to check the results of these seven years of training."
Lyon said with great interest. In the past, he wasn't very interested in participating in this kind of competition. Since Fairy Tail wasn't involved, winning first place didn't mean much.
However, now that Fairy Tail was back and had chosen to participate, the meaning of getting first place was different.
"Since Kael is participating, I have no problem participating either. Besides, it's not a bad thing to join a festival once in a while."
Jura said with a smile. Seven years of time had made Jura even more calm and collected. He hadn't participated before, partly because he had no interest in fighting for rankings, and partly because his participation would be somewhat of a foul.
Now that Fairy Tail was participating, it was only reasonable for him to join. After all, seven years ago, Kael had suppressed the Oración Seis single-handedly and even destroyed Nirvana in one hit. That kind of power, even now, was at the absolute top.
If the Magic Council hadn't been selfish, Kael would have become one of the Ten Wizard Saints long ago.
"Lyon and Jura are participating this year?!"
"Then we're definitely going to win!!"
"Lamia Scale is the best!!" ...
Everyone in Lamia Scale became excited upon hearing that Lyon and Jura had agreed to participate.
Mage Guild
Blue Pegasus
"Hmm... have you heard? Fairy Tail is going to participate in this Grand Magic Games."
Master Bob of Blue Pegasus said to Ichiya.
"That... that is truly a terrible parfum!"
Ichiya naturally remembered that monster Kael. That guy was excessively powerful. He was a monster seven years ago, and even today, he was still a monster.
Bob continued, "Besides that, Jura from Lamia Scale is also participating."
"Uh... the parfum is even worse then."
Jura's strength had progressed by leaps and bounds over these seven years. He had moved from the bottom seven years ago to the fifth seat of the Ten Wizard Saints today. He was not just a little bit stronger than before.
Kael's strength was great, and Jura was also not to be underestimated. These two guys were not people an average person could compare to.
"It looks like we have to step it up too..."
The news that Fairy Tail was going to participate in the Grand Magic Games spread rapidly throughout the Kingdom of Fiore. Even though for most people, Fairy Tail was a flower of yesterday and was currently nothing special.
But for those who knew or understood Fairy Tail, they couldn't help but pay attention to this news.
In the blink of an eye, three months passed quietly.
