Start by Eating Jake Jake no Mi

"BUCHOOOOUUUUU!!!" 

Issei had an ordinary face, build, and everything with a small ponytail, and he shouted with all of his might in front of many people. 

"Issei!" 

While Rias was startled, Riser was dumbfounded and embarrassed since how could this trash interrupt his party? 

Unlike Akeno, Kiba, and Koneko, Riser didn't invite Issei since he knew that this guy would cause trouble and might even cause shame to his family, especially when there were many lords and important devils in this hall. 

"Hey, how dare you—"

Yet, Issei ignored Riser and went on with his introduction. "I am Hyoudou Issei, a member of the Kuoh Academy Occult Research Club!" 

If this was all, then no one would say anything, but—

"BUCHOU'S VIRGINITY IS MINE!!!!" 

"....." Everyone. 

Masa, who watched this scene, fell into silence, never expecting someone to dare to say those words aloud without embarrassment. 

Yet, more importantly, he wondered whether Rias' blush was all due to embarrassment or shyness. 

This world was weird, he thought, since a woman could fall in love with such a maniac. 

'So, is that due to that?' 

Masa looked at the red dragon gauntlet on Issei's hand, wondering whether it had the ability to charm anyone who saw it.

However, it was good that Issei was ordinary and even a pervert, so that way, even if the Boosted Gear had an ability to charm anyone due to his pervertedness, it lowered its charm ability and only made those who were close to him to be moved and fall for him. 

As for those who knew nothing about him, they wouldn't have fallen for this guy at all. 

Still—

'Has this guy developed a "Dress Break"?'

Or did he not? 

After all, if there was a reason why Issei could develop the "Dress Break," a unique ability to tear up any clothes, it was all due to Asia, who would become his training object, but as there was no Asia, was he able to do that? 

As for Koneko and Akeno, while they might be close, they shouldn't have told all of their secrets to Issei, so their relationship should have developed. 

So what about Rias? 

Would Issei use his master to develop a "Dress Break"? 

'Probably not.' 

If Issei had such an ability, then Ravel should have mentioned it to him earlier, but as she didn't, Masa knew that Issei hadn't developed the "Dress Break"?

Still, since Masa had the ability of Jake Jake no Mi, then was it possible for him to develop the "Dress Break" too?

"....." 

'I am not a pervert, but this ability is useful, so let's try to learn it.' 

As Masa was in deep thought. Naturally, the followers of the House of Phenex couldn't let go of Issei, who broke into the party and did something outrageous, so all of them tried to stop him. 

"You are late." 

"Hurry up and go." 

"We will handle all of them here." 

However, when all of those followers wanted to stop Issei, Akeno, Kiba, and Koneko made their move to help Issei. 

"Everyone!" 

Issei was moved by their help before he charged forward. "Thank you! I will save Buchou!" 

Still, while Issei and the others fought with all of their might, everyone was confused and couldn't help but look at Rias. 

"Rias-dono, what's happening here?" 

Their eyes were full of blame since this was a place for a high-class devil to gather, so why should her servants cause a mess in this place? 

While Rias wasn't sure how to answer, her older brother, Sirzech, came to help her and said, "It's all due to me. I prepared a little entertainment for this party." 

"Who is that?" Issei was confused, but Rias was startled. "Onii-sama?!" 

"T-That's mean... he is a Satan?!" Issei was dumbfounded, but Riser looked at Sirzech with an uncomfortable expression. "Sirzech-sama, what do you mean by entertainment—" 

Yet, Sirzech stopped Riser from complaining and expressed his thoughts on the previous Rating Game. 

"Riser-kun, the Rating Game, was interesting to watch. However, against my sister, who was inexperienced and had less than half of her pieces, it was a bit..." 

"You have a complaint about that match?" Riser frowned. 

After all, the two parties decided to start a rating game, and no one objected to it from the beginning. Then, wasn't it too late for Sirzech to complain? 

"Not at all." 

Those words caused all of them to roll their eyes since if Sirzech didn't have a complaint, then would he even do this? 

"The Rating Game would become meaningless if I did. Not to mention, considering the circumstances involved this time, my old family would be dishonored." 

"????" 

Many were confused by Sirzech's words. 

Dishonor? 

What kind of dishonor is there after you have pulled up this kind of a stun? 

Yet, due to Sirzech's status, no one dared to say anything.

"I wanted something flashy for my little sister's engagement party." Sirzech then looked at Issei and said, "You boy over there. I wanted to see for myself the power of the dragon you possess, so I had Grayia make the arrangement.

"So, what do you think, Riser? A phoenix against a dragon. Wielders of the two legendary powers squaring off would make the party exciting, wouldn't it?" 

Yes, it was interesting, but could you search for a different time for this type of game?

Riser was annoyed inwardly, but what could he do? 

Still, he didn't think that he would lose to this pervert, but—

"Sorry to interrupt, but can I take a place in this battle?" 

"....." 

Everyone fell silent since no one thought that someone would come out to interrupt. 

Sirzech was the same and looked at the source of this voice with confusion. "Masa-kun?" 

Masa, who had been staying outside, remaining low-key, suddenly stood up and took all the attention to himself. "It is, after all, Riser's special day, so it isn't good for him to have a workout, right? His suit will get dirty. Let me handle this little entertainment game. A lion versus a dragon. It isn't bad, right?" 

Riser was dumbfounded when he saw Masa suddenly come to help him, but then, he thought that it might be because Masa felt sorry as he didn't prepare a gift by himself, which made him happy inwardly, thinking that this guy was still as thoughtful as ever.

"Okay, I agree! Masa beat him up for me!" 

"Okay, okay. You don't have to be so loud." 

Masa stood up, walking toward Sirzech, and never even glanced at Issei, and due to that, as expected—

"Oi! Who are you?! How you—" 

"Be quiet." 

"..." 

Issei immediately shut his mouth when Grayfia scolded him. Still, he glared at Masa, who was such a handsome young man, and more importantly, when he noticed Asia, who stood by Masa's side, he felt his heart ache and snorted inwardly, thinking that by defeating this guy, he could attract the attention of Asia! 

Yet, Asia was hiding behind Masa as she felt Issei's gaze was too... while it was rude, it was quite disgusting. 

Still, Sirzech was quite awkward by Masa's interruption and asked, "Masa-kun, do you want to join this game?" 

"Why not? It seems fun. I also want to see the power of the user of the Boosted Gear. Moreover, it is all the same, right? After all, you just want him to show his power to all of us." 

"Okay, let's do it!" 

However, Issei had no fear since no matter who the challenge was, he would do it to win against Rias! 

"..." 

Sirzech fell silent because of Issei. Yes, this guy's courage was good, but his stupidity was on another level. 

Many also started to giggle inwardly, thinking that it would be fun to watch this little entertainment. 

"Sirzech-sama, please let Masa fight in my place. If he loses, then I can let this engagement end," Riser said calmly. 

"What? Really? Then, let's do it!" 

Issei was excited, but—

"Stop running your mouth here!" 

"—?!" 

Issei was startled by Grayfia's anger, and meanwhile, Sirzech had a hard time maintaining his gentle image. Still, he took a deep breath and said, "I don't think it is fair for him to fight you, Masa-kun." 

"I also think that it is unfair for Riser to fight once again after he has won on the Rating Game that you two have agreed." 

"...do you really want to do this, Masa-kun?" 

"I do." 

As the two faced each other, no one said anything, but inwardly, they wondered where Masa got his confidence. 

Yet, there was no doubt that Masa made all of the members of the House of Phenex cry, feeling moved. 

"Good, but I have heard that you have a lot of lions that have a power that is comparable to an ultimate class devil." Sirzech looked at Masa without a smile like before and said calmly, "To make this duel fair, can you not use those lions?" 

"..." 

Everyone was speechless by Sirzech's words, but Masa only chuckled, then agreed with a gentle smile, "Sure, why not? I won't use my lions, so it will be fair, or do you want me not to use my Demon Power, too? Should I not use my hands, too, in this duel to make it fair." 

Naturally, his words caused many to chuckle, but all of them held it back since they were in the presence of Sirzech. 

"YOU BASTARD! DON'T LOOK DOWN ON ME! I WILL FIGHT YOU WITH EVERYTHING I HAVE!" 

Even if Issei's IQ was worrying, he knew that he was being made fun of. 

"Okay, then, if that's the case, I will use everything I have."

Masa appeared helpless, but he could only nod to Issei's wish. 

"..." 

Sirzech felt that this boy's IQ really was so low that it caused him to be dumbfounded. 

"Sirzech-sama, please let me do this! I will definitely win this, and Buchou, please wait for me!" 

Issei's eyes were blazing with excitement, thinking of the woman who had saved him, and like how she had saved him, he would save her! 

No matter how strong Masa was, Issei would win! 

With the power of the Welsh Dragon, no one could stop him! 

"Okay, then..." Sirzech sighed helplessly, then looked at Masa. "By the way, don't forget your words, Masa-kun. Don't use your lions." 

"..." Everyone. 

"You don't have to worry, Sirzech-sama; since it is entertainment, then it won't be fun if I use my lions, right?" 

This was the time for him to change the rules within the Underworld. 

Lucifer, the leader and the king of the devil, should be placed with someone who is more suitable. 

Then, with that, the duel between the dragon and the lion started.
