Training Arc 1

When they left the gathering, they quickly went to his villa, preparing for Sona's and her peerage members' training. During this time, no one mentioned Rias, but they talked about what Riser was going to do with Koneko.

"I will let Ni and Li train her."

Ni and Li. 

Even if they were just pawns with one piece of Evil Piece, there was no doubt they had become the strongest reincarnated Nekoshou. After their training with Magari (the leader of Nekomata, eight-tailed Nekomata, who is part of the East Youkai Faction), they had become stronger. Moreover, their tails had increased to three, and they were about to grow four tails. 

There was no doubt that there was no suitable person to teach Koneko other than Ni and Li. 

While Riser could teach Koneko, he wanted to focus on Sona and her peerage members, especially when Koneko was part of Rias' peerage, who also happened to be Sona's first opponent in this Rating Game gathering. 

Leaving Koneko with Ni and Li, Riser brought Sona along with her peerage members to the training room in his villa.

Naturally, Serafall didn't miss this chance and also followed as she wondered what Riser was going to do. 

However—

"Give me your body's sizes." 

"....." Everyone. 

"Didn't you know already, Riser-sama?" Xenovia asked in doubt. 

"....." Riser. 

"....." Everyone. 

Riser's lips twitched as Xenovia was correct. With his "Mathematic Mastery," it was possible for him to know everyone's sizes with just a moment of glance, but wasn't that creepy? If he suddenly knew their sizes, what would they think in their hearts?

"While I know that you won't do something strange with them, can I ask what you are going to do with everyone's sizes?" Sona asked calmly as she pushed the frame of her glasses. 

"Do you know who you need to watch out for when you have "Rating Game" with Rias?" Riser asked. 

"...Rias?" 

Hearing Sona's answer, everyone nodded as there was no doubt Rias was the strongest. 

"No, it's that perverted dragon?" 

"Why?" 

Everyone became confused by Riser's answer. 

"Is it because of the Boosted Gear?" Sona asked with a frown, but she couldn't make the connection between the Boosted Gear and their sizes. 

"No." Riser shook his head. "The Boosted Gear isn't something that you need to be wary of. This Longinus might be powerful, but its user is trash, so there is no need to worry, but even if the user is trash, you need to watch him out." 

Sona quickly realized something. "Don't tell me..." 

"What? What is it?" Serafall asked curiously. 

"Yes, it's his "Dress Break" that you need to watch out for." Riser nodded. 

"...." 

Everyone fell into silence, and their expression turned into worry when they heard Riser's answer. 

Dress Break. 

While they didn't want to know, it was impossible for them not to know, especially when this technique was so perverted. 

The first match between Rias and Riser wasn't a secret, and it was something that Sona and her peerage members had watched previously. Honestly, the one-sided match wasn't something they remembered the most. Instead, it was Issei's perverted technique where he stripped the clothes of his opponents, something that they remembered the most. 

Even Xenovia was familiar with this technique and also showed a frown of disgust. 

"I will create a uniform for all of you, so this technique won't work for you." 

"Thank you very much." 

All of them thanked Riser at the same time. 

After all, who wanted to get naked because of Issei?

"Still, his pervertness is something that you need to watch out for, so you need to be careful." 

"R-Really?" Even Saji was flabbergasted, wondering how such a pervert could become a dangerous element in their first "Rating Game." 

"Don't let your guard down, Saji. Give everything to you to fight him. If you lose, you will shame everyone." 

"Yes, Riser-sama!" 

Sona might be Riser's wife, but even so, as a member of her pawn, Saji wished to show his best! 

Sona thought for a moment and asked, "I am just curious... how dangerous will this pervert become?" 

Riser thought for a moment and explained. 'The Boosted Gear' aside, his technique will revolve around something that is related to his perverted desire, so based on his first technique, which is "Dress Break," I can imagine that he will create another pervert technique." 

"Such as?" 

"Er... a technique that makes him able to talk with breasts? Getting stronger by touching breasts? Or... using breasts as a communication tool?" Riser wasn't sure, but he felt that Issei should be able to create such a technique. 

"...." 

They opened their mouths before they closed them again. 

"You don't need to worry. This uniform is something that I will prepare for you to counter all of his perverted techniques." 

Hearing his words, everyone felt relief. 

"Saji, go away, turn, and close your ears." Sona quickly gave an order to Saji before everyone exposed their sizes to Riser. 

Saji was speechless, but he followed Sona's words, walking a few kilometers away until he was called again. Still, when he returned, he saw everyone had blushes on their faces, which made him sigh helplessly. 

Recording all the female members' sizes on his note, Riser then looked at Saji and asked, "Saji, what's your size? I will prepare a uniform for you." 

"Ah, yes, Riser-sama!" Saji quickly reported his size to Riser as he also wished for a new uniform prepared by Riser. 

As Riser made a note, Xenovia suddenly asked, "Er, Riser-sama, are we not going to have a Mocking Gear like everyone else?" The "we" she mentioned were herself, Tsubaki, Saji, and Sona. While Riser hadn't shown what kind of Mocking Gears he would give everyone else except for them, she knew they would be amazing, and naturally, she also wished to have one. 

"There is a technique that I want you to master, but let's see... I guess you are right. I will lend you something later." 

Riser felt that while Xenovia had a Durandal, that wasn't enough as the Holy Sword was only a sword, and it wouldn't be a problem if he gave her something else, and he got something perfect for her who had a muscle for the brain. 

"Yes!" 

Still, hearing Xenovia's cheers, Tsubaki, Saji, and Sona also stared at Riser, hoping they got the Mocking Gear. 

As for Serafall? 

Riser directly ignored Serafall and then looked at Tsubaki, Saji, and Sona. 

"I know that you also wish for something similar, but unlike them, Tsubaki and Saji, you have Sacred Gears. You two should focus on mastering those powers instead of using the Mocking Gears." 

Whether Tsubaki or Saji, they had limitless potential, especially when they were Sacred Gear users. Moreover, their Sacred Gears weren't weak, especially when Tsubaki held a hidden power inside her body, and Saji's Sacred Gear was a Dragon-type. 

While Riser knew that giving them a Mocking Gear could make them stronger, he wished for them to master the power that they had over themselves. Moreover, if they reached their limit, then it wouldn't be too late for him to give them a new power, right?

As for his wife?

"Sona, you should also master the power of Sitri House first. I will train you personally later." 

"Yes." 

Sona never felt worried as she knew her husband knew the best of her, but at the same time, she wondered how he was going to train her. 

"..." 

Watching Sona, who suddenly blushed, Riser rolled his eyes to the sky before he coughed and said, "Now, during this month, I hope that you can focus and give your all, alright?" 

"Yes!" 

Given their firm answer, they were prepared for this training arc!
