Looking at the grand castle before them, Rias Gremory felt slightly nervous, but she wasn't the only one. Instead, all of her followers, whether it was Akeno Himejima or Kiba Yuuto, also felt the same. 

Yet, among them, two within the group unexpectedly showed a different reaction. 

Issei Hyoudo was obviously annoyed and furious, thinking of what had happened previously. At the same time, he was disappointed and felt an intense regret as he was unable to bring victory to his master. If there was something fortunate, it was the fact that the House of Phenex decided to stop the engagement with Rias, as this family didn't think that Riser should become the husband of Rias, considering how hypocritical the House of Gremory was. 

However, this brought Issei happiness instead, knowing that Rias' boobs wouldn't fall and be played by Riser! 

Still, he ignored how much his master had been humiliated. 

Yet, instead of those things, Issei's focus was on something else, and this was the most critical since without that "thing," he knew that he was as good as worthless, and he didn't want to become a burden for his master, so even if his body was in pain, he forced himself to go since he wanted to get that "thing" back as soon as possible. 

However, unlike Issei, who had negative thoughts, Koneko Toujou, Rias Gremory's Rook, appeared curious as she kept looking around curiously yet quietly. Her childhood experiences told her no one could be trusted, and she couldn't even trust her master as she wasn't sure when Rias might betray her. 

Her older sister could betray her, so it was obvious that Rias could do the same, right? 

Koneko's heart was tightly closed, and no one could open it; regardless, she started to show her curiosity toward a certain young man who had been on her mind lately.

'The House of Vapula...' 

Koneko murmured that name inside her heart as she had never paid attention to another family of devils, nor was she interested in them since she had been thinking about saving her life all the time. Being a servant of the House of Gremory, especially Rias, the heiress of this house, was probably something amazing for many, but she didn't think so since, in the end, it couldn't change the fact that she was just a servant.

Or even a pet in Rias' eyes. 

The society of the devil was feudalism, and everyone could only become a high-class devil through their origin and birth. It might be possible for the servants or a low-level devil to raise their status, but one needed power, or else, even if they had done many things, they could do nothing. 

Yet, the House of Vapula was different since, along the way, Koneko saw many cats, lions, and many types of feline creatures that attracted her eyes. While she knew that it was wrong, she felt that this place was more like... her home, especially when she could see the eyes of those feline creatures never showing fear toward their master, only admiration, loyalty, and even worship. 

'What is this feeling?' 

Koneko wasn't sure, but her body had been strangely hot, and her cute cat's tail just couldn't stay quiet when she came to this place... and while she was quite nervous, she wished to meet that young man again. 

However, as Koneko was relatively discreet with her actions, Akeno was nervous, especially when she thought of Masa's strength that day. The power of the Boosted Gear, no, Ddraig, was immense as it was the dragon that pushed the God of the Bible to pass away, so even if it had died and its soul was sealed inside the Longinus when it took over its host, it became a monster that caused destruction everywhere. 

Yet, despite how strong Issei had become, Masa could defeat him. More importantly, was Issei telling the truth about his condition? 

Lastly, was it okay to bring Issei here? 

"Rias..." 

"I know..." 

Even Rias understood that it was risky to bring Issei, especially given how idiotic this guy was, but she was confident that Masa wouldn't kill Issei. 

While she didn't like this fact, it was because she was the little sister of Sirzech Lucifer. 

Due to this fact, Rias was confident that Masa wouldn't do anything. 

'More importantly...' 

When she thought of Issei's strength that day, even if he had lost, she knew that he was an important part of the House of Gremory as he could boost the power of her house, so even if her servant had caused so much trouble that her family was under the attack of many nobles that it caused her image in everyone was damaged, it was impossible if she didn't feel disappointed toward Issei. 

Not only was this guy such a creepy pervert, but he also failed. 

'If it's like that, don't give me hope...' 

When Rias thought about her current reputation, she felt heavy and angry, yet she could do nothing to change the situation. At the same time, when she glanced at Issei, she had a certain doubt in her mind. 

Yet, did Issei really tell the truth? 

Rias knew that this was an idea toward her servant, but she couldn't help it, especially when Issei had become powerless, and the eight pawns of Evil Pieces had been wasted on him if he really couldn't regain his power. 

Based on what Issei had said, his Boosted Gear was taken away from him by Masa. 

However, Rias felt doubt about those words since she knew that anyone whose Sacred Gears were taken would die right away. Even the fallen angel, who had the most advanced research on the Sacred Gears, couldn't do anything about that, so could Masa, who was just a young man, even younger than her, who took out the Boosted Gear from Issei without killing Issei. 

Or rather, it wouldn't be weird for Masa to kill Issei directly!

More importantly, with Masa's strength, did he even need the Boosted Gear? 

Instead of Issei's delusion that the Boosted Gear was taken by Masa, Rias believed that Issei was as good as useless after he had gone on a rampage. 

Juggernaut Drive. 

After Issei had woken up but lost his ability to use the Boosted Gear, it was impossible for all the members of the House of Gremory to remain silent, and they quickly tried to gather all the information about the Sacred Gears that they could collect, and the answer that came from that was due to his body having become crippled, so he had become so weak that he could no longer use the Boosted Gear or the Boosted Gear had been destroyed after it had gone rampage. 

Either way, Issei was no longer able to use the Boosted Gear didn't change. 

Still, if Masa could return the Boosted Gear, it would be good, but if he couldn't, or if Issei was lying, then...

Rias didn't say anything, and she just waited in the waiting room inside the headquarters of the House of Vapula, which made her, Akeno, Kiba, and Issei all tense since all of them were frightened. 

'This power...' 

Compared to Rias' house, the House of Gremory, even if it was led by the strongest devil in the world, Sirzech Lucifer, the House of Vapula was more comprehensive, whether it was military, economic, or political, as it was close to both the Four Great Satans through Serafall and the Great King through Misla. At the same time, it also had many powerful subordinates whose power was similar to those of high-class devils and even the ultimate-class devils. 

Somehow, when Rias thought of Ravel, she couldn't help but be jealous, thinking of that confession, wondering why it wasn't her but Ravel. 

Still, Rias knew that she couldn't mess up this meeting, which made her somehow agree to Akano's words, who thought that it was better to leave Issei instead of bringing him.

'Now that you mention it... why did I even bring him?' 

As Rias thought so, the door was knocked for a moment, and soon a maid came, but before saying anything, the maid bowed her head and apologized, "I am sorry, but Masa-sama is too busy, so he can't meet you, Rias-sama." 

"..." Everyone. 

Yup, if Rias wanted to meet Masa, then she had to bring a companion such as her older brother or parents since even if they were both heiress and heir, they were completely different as one was only spending her time on her hobby, and completely spoiled due the pampered of everyone around her, especially her older brother, but on the other hand, Masa was an heir, who had created the House of Vapula to the peak, yet, how could she accept it? 

"...what?" 

However, Masa was really busy. Why? 

It was because the three bitches that he slept with were in big trouble.
