Everyone was dumbfounded by Riser's words, and no words came out of their mouths. If it were others, Rias and the others would refute it, but this was Riser; no matter how strange it was, if he had said there should be a reason, and even if there was no reason, no one could escape from it.
Gasper, who was suddenly told by Riser that he had become a criminal, was so scared that he had just gotten stuck in a place.
"Not now, but in the future," Riser said calmly as he sipped a coffee brew by Akeno.
Gasper wanted to refute as he was nothing but just a shut-in. Why should he make trouble for Riser, especially when his life was so comfortable? While it was a shame about Issei, it didn't mean that he couldn't move on, and Riser was completely unrelated to the death of Issei.
Even if Riser was related, Gasper didn't think that Riser did anything wrong, especially with Issei's rude conduct, as he knew most of the news in this world through the internet, and he also often heard Issei mocking Riser. Even if he wanted to stop it, there was nothing he could do since Issei's brain was too small, so after he tried to talk to Issei, Issei would forget about it.
Nevertheless, how could he become a criminal?!
"Wait! Dear, what do you mean...? In the future?" Rias asked in confusion.
At this moment, those who could talk freely with Riser were only Rias. While the women in Rias's peerage group could talk to him, they knew that it was inappropriate for them to talk about what he should do. Moreover, as he came to talk instead of catching Gasper directly, there should be a solution to this problem.
"You remember what happened in Kyoto, right?"
"Kyoto?"
"When I was about to end the Hero Faction, there was someone who stopped my attack, and this person should be at the level of Super Devil, a devil who was similar to your big brother and deceased Ajuka."
"..."
Everyone fell silent; then they quickly matched Riser's explanation with Gasper's.
"So... that person is the future Gasper?"
"Yes."
"..."
"But... how?"
"It's his Sacred Gear."
"Sacred Gear?"
"Gasper's Sacred Gear, Forbidden Balor View, like other Sacred Gears in this world, would evolve, and he would become so strong that he had become a Super Devil. While I am not sure how he can come to our timeline, at this moment, he should be helping the Khaos Brigade to destroy the alliance."
Gasper wanted to say something, but he couldn't, yet he wanted to curse his future self as this guy had caused trouble for him!
"You don't need to worry. Even though I said that it was a future Gasper, it might be you from a different parallel world."
"Different parallel world?!"
Rias frowned and asked, "Then, why did the future Gasper come to our timeline and even help the Khaos Brigade destroy the alliance?" She wondered what was wrong with Gasper's future to be able to make such a decision.
"This is a parallel world. There might be a difference between their world and our world."
"Difference?"
"Yeah, it's like I am not the leader of the alliance, and I am not the strongest. It might be someone else who is the strongest."
"Then...?"
They even became confused and wondered why Gasper from the future came to their world.
"Well, if they came to our timeline, then there was only one reason."
"What?"
"It is because I attack their world."
"....." Everyone.
"...will you?" Akeno asked curiously.
If this was someone else, they wouldn't think that someone dared to attack the parallel world, but if it was Riser, they believed that he dared to do so. It was like how he dared to have a war with the Chinese and Hindu myth.
So, after that, he was going to attack the parallel world?
"No."
"Huh? Really?"
"What's with that expression? I have never thought that the parallel world even exists, to begin with, but somehow, this is the only explanation why Gasper from the future decided to become my enemy."
In this parallel world, Riser could somehow imagine that the leader of that world should be Issei instead of him.
"However, since this Gasper decided to become my enemy, then I will come to dominate their world."
"..."
Everyone fell into silence and wondered what was wrong with Gasper's head from the future. If they lived by minding their own business, then would this be a battle between two parallel worlds?
Still, if there was someone who wanted to get angry and cry at Gasper from the future, then it was a Gasper from this world since, due to this Gasper from the future, he was the most affected.
"You don't need to worry, Gasper. I won't kill you."
"R-Really, Riser-sama. Thank you very much!"
Gasper was crying and bowed his head several times.
"But I will take your Sacred Gear. Is that okay with you?"
"Eh?"
"You don't need to worry. You won't die after I take out your Sacred Gear, and I will give you a new power."
"Please!"
Gasper directly agreed after Riser finished his words.
"Are you sure?"
"Yes, Riser-sama. If this can erase the suspicion on me, then I will do anything."
Gasper's eyes were firm since, if possible, he wanted Riser to take his Sacred Gear as soon as possible.
Riser smiled and said, "To be honest, the reason why I took out your Sacred Gear is also for your own good."
"???"
"I am not sure whether this Gasper from this future has this kind of power, but I am afraid that he might make himself stable by invading your body, dominating you, making your body into his, so he will become powerful."
"...." Gasper.
"The connection between you two is the Sacred Gear, and there is no doubt that he is more powerful, so I take out your Sacred Gear so your body won't be taken by him."
"Thank you, Riser-sama."
Gasper's face, which was already pale, became even paler as he thought that his body would be taken out by Gasper in the future.
Still, others would be even more so since if Gasper became Gasper from the future, would they be able to realize that it was him or him from the future?
If this was possible with Gasper, then what about the others?
"You don't need to worry. It is only Gasper, not the others."
"I-Is that so...?"
After all, who wished their bodies to be taken out by their parallel selves?
Riser was about to take out the Sacred Gear from Gasper's body, and everyone was present as he didn't mind showing this ability of his to them.
"By the way, Dear, if there is a parallel world, how will it become?"
"Hmm? What's wrong? Are you curious?"
"Well, it is impossible if I am not curious, right?"
"I can't give you an answer since there will be an unlimited possibility."
"For example?"
"For example, the Khaos Brigade dominates the world, all the supernatural beings are killed by the Hero Faction, the church becomes the only force, and even Issei becomes the strongest of all beings. There are many possibilities that it is impossible to count."
"....."
Everyone looked at Riser with a joke-like expression since they felt that this guy had completely said nothing but nonsense as they couldn't imagine such a future, especially when he told them that Issei had become the strongest being. Even though they still remembered Issei, it was also because of this they didn't think that the perverted boy could become the strongest.
However, Riser only rolled his eyes since he told the truth, but why didn't they believe it? Still, either way, as he had taken out the Sacred Gear from Gasper, he knew that the path for Issei and those who came from the parallel world had become so narrow that it was impossible for them to fight him.
