"...are you going to be okay?" Sato Maken-Ki looked at Sato DxD with a complicated mood.
"I should be okay."
Yet, Sato DxD was as calm as a cucumber, or probably, he had resigned himself. Then again, with what had happened to him, especially with his relationship with Grayfia and even Issei's mother, he felt that his relationship with Sona and Tsubaki was tame or even at a level that he could handle, forgetting the fact that Sona's older sister was a doting, protective, and a little crazy.
"..."
Yup, he might not be okay, he thought.
"Isn't it fine? Your level should have reached the original Satan, right?"
Sato MHA felt otherwise since Sato DxD could duplicate the King Piece; their strength had reached the original Satan, who waged the war against heaven to dominate the world, but—
"... Do you think the original Satan is strong? The Satan class of devils is strong, but when you compare them to those creatures that stand at the top? They are nothing."
At this moment, Sato DxD knew that his strength was probably similar to a nuclear explosion, which made him capable of destroying a city or two if he wanted to.
No, wait, he could destroy the planet if he wished to.
How?
By using his Starsend Moment, he increased the possibility of tectonic earthquakes occurring worldwide, causing tsunamis and widespread destruction, which ultimately led to the end of the world.
Unless the earth itself had its own entity or will, it was impossible to stop the catastrophe caused by his Starsend Moment.
"...."
Wasn't he so powerful?
Sato didn't think so since, in many cases, some kind of gods in various myths, or even gods in various major religions, had a power that could affect the cosmic level.
More importantly—
"The King Piece is just a tool, and it isn't our original power."
Yup, even if the King Piece was impressive, in the end, it was just a tool, and their original strength was more or less still similar to before.
"Well, at least we can protect ourselves now."
Sato Fairy Tail felt that they had gained a lot of things, and instead of worrying about many things, it was better to just acknowledge their hard work.
After all, if Sato DxD hadn't developed his Twice Critical, which he could even make a double of the King Piece and the Sacred Gear, then they could do nothing, right?
It was also because Sato DxD kept working hard consistently, day by day, that he could also call upon all of them together and grow stronger together.
"Thank you."
"Then again, you should be prepared." Sato Fairy Tail seemed about to remind Sato DxD of something.
"What do you mean?"
Sato DxD was confused by the sudden change of tone from Sato Fairy Tail.
"You have just lost your virginity, right? I think that you should be careful since Sona and Tsubaki aren't going to be the only ones. Rias, and the others are going to follow, and they will get your seeds no matter what the methods, even if they will drug you."
"..." Sato DxD, Maken-Ki, and MHA.
You are joking, right?
Yet, Sato DxD didn't have confidence that he could protect himself, or had a strong will to stop falling to their seduction. When he thought of the appearance of the elegant beauty of Tsubaki, and the noble, yet stern Sona, stained by his semen as they licked him at the same time, sucking his penis lovingly, it gave him a shiver, knowing that it was impossible to stop after he knew those feelings.
When he was inside them, and as they reacted, they cried lewdly under him, wishing him to impregnate them; it was just too sublime.
Still, Sato MHA and Maken-Ki aside, as they were still single, Sato DxD looked at Sato Fairy Tail in silence.
"W-What? Why are you looking at me like that?"
Sato Fairy Tail was a little flustered. "I have a girlfriend, you know?"
The three of them snorted at his words, causing Sato Fairy Tail to be speechless.
"Do you think I dare to make a move on others when my girlfriend is like that?"
As that question fell, Sato MHA pointed at Sato DxD and said, "This guy had the wife of Lucifer to give him hands and blowjobs so many times. By the way, how many times have you had cum on her?"
"..." Sato DxD.
How many times?
However, if on average he would cum five times, and if one multiplied that by the week of the training camp that he spent with Grayfia, then it meant—
"Anyway, we need energy! As long as we have energy, we can become stronger!"
"....." Everyone.
Still, his words weren't wrong since as long as they had enough energy, they could grow stronger.
The King Piece was amazing, but it had a limit on improvement, as it could only make one reach the power of the Satan-Class of Devil, and more than that, it was impossible.
Yet—
"Frankly, you need the Boosted Gear. The other, Longinus, is fine, though."
"I think it is better for you three to explore your world first, especially you, Maken-Ki."
DxD and Maken-Ki were similar since they had a similar power concept, as they relied on the artefact created by the higher beings.
Once again, if Sacred Gear from DxD was created by the God of the Bible, then Maken from the Maken-Ki was created by the birth of the gods in Japanese mythology. There might be other sources from other mythologies, but the main setting of Maken-Ki was in Japan, so it had to be the Japanese mythology.
Lastly—
"The improvement in DxD is limited and long-term. The fastest way is to rely on others, but we have secrets that we can't tell anyone, especially those deities or gods that have strange powers that might be able to read our minds, or even mind control, so I have to be careful."
As Sato DxD grew stronger, he also felt even more helpless since more people would stare at him.
As for Sato MHA, the moment he got All-For-One, he had nothing to do and had just been training with the Quirks that he got.
As for Sato Fairy Tail... hmm... it was a bit hard to describe somehow. While there were a lot of ways for him to grow stronger, there were also a lot of limitations.
"Be the Dragon Slayer, Sato!"
"Dragon Slayer..."
Sato Fairy Tail was speechless when he thought of Natsu and all other Dragon Slayer Magic users, but he had to admit that it was the fastest way to grow stronger.
Still—
"Compared to me, why don't we just summon another Sato?"
Yup, the fastest way was to summon another Sato, increasing their numbers, and as their energy had increased further due to the King Piece within their body, it should be possible, right?
"...should we?"
