Everything is peaceful

Stray devil. 

While this term might have been unfamiliar before, it was a new term that came from those reincarnated devils who diverted away from their masters for their own selfish desires.

Without their masters to keep their powers in check, they became a great threat if their powers went beyond their control.

Yes, it could be said that for the devils, those stray devils were the greatest criminals ever, and killing them on the spot was their punishment. 

Yet, while Masa knew that the truth wasn't so simple, he simply ignored it since this was what everyone wished to believe, and it was too troublesome for him to fix everything unless there was a benefit that made him believe that it was worth taking a risk. 

Masa came from a noble family, and he was someone at the top, so he knew everyone's attitude toward their reincarnated devils, which was even lower than that of a low-class devil, so there was no doubt that those servants of Sona and Rias should be grateful since those two heroines were kind and gentle. 

Still, he was a bit curious, wondering how those stray devils could escape from the Underworld and whether there were so many of them in Kuoh City. 

"There are many ways for them to come here, whether it is by teleportation magic, unique, innate ability, escape when their master visits the human world, and many other things." 

"So, you often met them?" 

"Yes." Sona nodded and said helplessly, "Unexpectedly, there are many of them." 

"..." 

It wasn't unexpected, but it was normal, he thought, but he decided not to bother to think too much since his purpose in coming to this human world wasn't to see the cruel reality that happened among the reincarnated devils but instead to become stronger. 

After all, in the end, it was the only strength that one could rely on. 

Issei might be a perverted boy who was even known as the "Dragon Breasts Emperor. " It was such a funny and idiotic title, yet everyone would open their legs wide for him; why? 

It was because Issei was strong!

Every tragedy in this world happened to an individual because they were weak and unable to change or protect who they loved, so he knew that he shouldn't be distracted and should focus on his goal. 

"How about you? Do you often fight in your domain?" Sona asked curiously. 

"In the beginning, when I wanted to experience a battle, I used to fight a lot, but not now. It has been a while since I fought. We have our own army, and you know our power, right? We have many lions that patrol within our domain, so there is no need for me to come out by myself." 

Masa was the heir and the leader; instead of bothering himself with small matters such as fighting and catching criminals, he should focus on developing his domain. 

After all, were there any world leaders who went to the battlefield by themselves? 

In the past, Alexander the Great, Julius Caesar, Genghis Khan, and Napoleon Bonaparte might have led their armies to fight, but if so, then how could Masa manage his domain?

"Now that you mention it..."

Masa was a devil from the House of Vapula, and instead of fighting by himself, wasn't it normal for him to summon his lions to fight? 

"But you don't have to worry." 

Sona wasn't sure how strong Masa was, but even if he was weak, it didn't matter. "I will protect you." She thought that Masa had been away on the battle for so long as he had been governing his domain, but she didn't look down on him and thought to protect him instead. 

"...." 

Masa looked at Sona, who was much more petite than him, saying those words with a solemn expression, wondering whether she thought of him as a weak devil. Still, he didn't bother to explain and nodded softly. "That's reassuring." 

Nevertheless, Saji sighed in relief when he heard Masa's words, thinking that it might be his chance to show how awesome he was. 'Sacred Gear...' He thought about the hidden power that resided within his body and thought that this was the power that could help him to grow stronger and become the strength of Sona, the one who had pulled him away from the darkest abyss. 

Masa wasn't sure what Saji thought since he didn't have a mind-reading ability, but he had never expected that the first time he came to the human world, he would immediately see the stray devil. 

At the same time, he also wondered whether those famous fallen angels in the beginning were still living. To be honest, he didn't care which fallen angels he devoured with his Jake Jake no Mi since, in his mind, they were all the same, and as long as he could gain the holy property, his goal was as good as being completed. 

Nevertheless, as it had been decided that they would have to hunt down this stray devil for a moment, Masa followed Sona and her peerage group, using teleportation magic toward the location where the stray devil appeared. 

"Is this the place?" 

"Yes, the signal is here." 

The place where they appeared was the entrance of a large, abandoned mansion located in the middle of nowhere. 

Masa felt that this was a cliche thought, and at the same time, he felt that it might be better to just destroy this whole building to kill the stray devil. However, Sona was the governor of this city, so he decided to leave everything to her. Still, he used his Observation Haki to detect where the stray devil was, and soon, he found its location. 

'As expected of the Observation Haki.' 

The Haki in the world of One Piece might be a simple ability, but even so, they were handy and powerful. 

'Still, this number...' 

Masa was speechless and wondering whether this was a trap, considering the number of presences within the mansion, and most of them weren't even stray devils. Instead, they were all completely different mythical races, he thought. Still, he decided to confirm this problem with Sona. 

"By the way, Sona-nee, how many stray devils are there?" 

"How many? There is only one stray devil, Masa." 

"Oh?" 

Masa looked at Sona for a moment, then nodded. "I see." He decided not to remind her since he felt she might not believe in him as she believed him to be weak. Nevertheless, even if there were many of them, they were just small fries in his eyes, and he could handle all of them in case an unexpected situation happened. 

"You don't have to do anything, Masa. My peerage members and I will fight this stray devil." 

"Okay. I look forward to it." 

Sona had a confident expression on her face and then looked at her peerage members. "Everyone, let's give our all to punish this stray devil!" 

"Yes, Kaichou!" 

With those words, everyone entered the abandoned mansion with a spirit, yet suddenly, a barrier surrounded them and trapped them inside. 

"Huh?!" 

Sona and the others were startled, and all of them became tense due to the unexpected situation before them. 

"Finally, you have come, the little sister of Maou! That black hair? You are not the Gremory, huh? Then, I guess you must be the little sister of Serafall Leviathan!" 

"...who are you?" 

Sona frowned, watching a man who dressed like a host club member. Most girls would scream like an idiot if they saw him, thinking that this person was handsome, but for her, who had seen Masa, she didn't feel anything, and this level of good-looking appeared ordinary in her eyes. 

The man had long blonde hair and a white suit and appeared arrogant and lustful at the same time. "Don't be so cold. Aren't you looking for the stray devils? Here you go. You can have it." 

Then, all of a sudden, many men with similar fashions came out one after another as they threw one stray devil that was half-dead into the hall of the mansion, clearly beaten up by all of those men. 

Yet, Sona and all of her peerage members also realized that they were all completely surrounded! 

Still, while Sona was a bit nervous, she didn't lose her cool and thanked the man without lowering her guard. "Thank you, then." 

"No problem~! No problem~!" The man laughed happily, hearing Sona's words, then said, "But shouldn't you give me a reward for my service?" 

"...what do you want?" Sona had expected this and clearly understood that this man didn't have a good intention from the beginning. 

"Be my harem member! No, bring your sister too! All of your Sitri Clan will be our slaves! That's my wish!" 

"Kekekeke!" 

As the man's voice fell, everyone laughed happily as they looked at Sona and her peerage members with lustful eyes. 

"...do you wish to die?" Sona was furious as her Demonic Energy exuded dangerously

Did this guy think that her family was so weak? 

How did this guy grow a confidence that all of them could defeat her older sister and her family? 

Yet, Sona had to say that all of them came prepared, and this would be a difficult battle, especially when she also had to take care of Masa's safety. 

"Oh? How festy! But can you keep that composed face for long~?" The man licked his lips disgustingly and said, "I changed my mind! I will rape you now! Guys, attack them!" 

Hearing those orders, everyone suddenly transformed into anthropomorphic rat monsters that appeared disgusting and frightening at the same time. 

"H-Huh? What are they?!" Ruruko Nimura, Sona's pawn, hadn't been in the world of the supernatural for a long time, so her entire body was filled with disgust and fear when she saw all of those strange monsters. 

"Kyuuso..." Tomoe Meguri, Sona's knight, who was also part of the Meguri Clan, a famous exorcist in Japan, quickly identified the identity of those monsters. "They are evil rat youkai, who often raped women and killed as they wished." 

"What?!" Saji was dumbfounded and felt nervous when he thought about how all of Sona and everyone became the target of this disgusting youkai! 

Everyone, including Sona, was nervous by the sheer number of evil youkais before them. More importantly, none of them could escape as a barrier made them unable to use teleportation magic or ask for help, but Masa suddenly said, "Do you mind if I attack them?"

"Ah, huh?" 

When Sona was confused, Masa stopped playing around and made his move by stretching his hand forward and— 

BOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMM!!!!

All of a sudden, powerful forces blasted all the rat youkais and smashed their bodies into pulp, killing all of them instantly before they were able to do anything, including the stray devil that was caught. 

Yet, at the same time, a powerful force shook the earth and destroyed everything, causing a small earthquake in Kuoh City and the surrounding city. 

"W-What's happening?!" 

"Earthquake? Is there an earthquake?!" 

"Isn't it a bit too big?!" 

Those who lived in Kuoh City and surrounding cities were startled and panicked because they could feel the sudden earthquake. 

Nevertheless, watching all of this, Masa felt comfortable somehow since how could he let Serafall's little sister be molested like that? 

"..." 

Still, Sona and everyone who was ready for the battle were stunned in a place as they saw all of their enemies were killed instantly by Masa. At the same time, half of the mansion was destroyed, or rather, almost everything within a hundred meters radius had collapsed, and the earth was gouged deeply by something as if a new lake was formed. Watching the carnage and destruction before them, all of them sucked a deep breath, and they turned their heads slowly, looking at the young man whom they thought they should protect. 

"Sorry, I destroyed the building." 

"....." Everyone.
