After he ate this Devil Fruit, Riser conjured a green, gel-like collar.
Peto Peto no Mi.
It was Devil Fruit that gave him the ability to control any living creature by giving them a green, gel-like collar.
When he thought about the ability of this Devil Fruit, it felt like he had become a slave master somehow.
Yet, how could it not be?
After all, as long as any living beings were caught in the collar, they would become his "pet" and would follow every one of his orders.
Nevertheless, he had to admit that this ability was scary since if he wished to, he could control any living beings, including those gods, supernatural beings, and the rest.
Riser knew that it was even possible for him to control Tannin.
Yet, even if this ability was amazing, there was a weakness of this ability.
The first weakness was that this ability only worked when one was caught on the collar, so if they weren't caught, he couldn't control them, and with enough speed, it was possible for one to dodge the collar.
The second weakness was that Riser could only control his victims' bodies; he couldn't control their consciousness and senses, allowing his victims to come up with plans to escape from his control.
The third weakness was that the victim must be able to hear and comprehend the command for it to take effect before it works.
The fourth weakness was that as long as the victims exerted enough willpower, they could resist the commands.
Yet, those weaknesses were easily solved.
The first weakness could be solved by using "Area of Invisibility" or changing the collar color, so no one could see when he threw the collar toward them.
As for the second weakness, as long as he made an order beforehand, telling them not to escape even if their consciousness tried to think of a countermeasure, it was meaningless.
The third weakness was even easier to solve as he could give a command through telepathy magic. By then, he could send his order directly into their brain without even saying anything.
As for the last weakness?
If they couldn't be controlled, then he would kill them.
That's it.
Everything was easily solved, yet he had to say this ability was scary, and he might as well have kept this ability a secret.
Still, suddenly, he thought of an idea. He took Twice Critical from his dimensional storage, and a black gel-like substance was released from his palm and enveloped around Twice Critical. Even though he had gotten this Sacred Gear, it didn't mean that he could use it.
Probably, due to the consciousness within the Twice Critical noticed that he hated a dragon, which made him unable to use it. However, it was meaningless, especially when the dragon used to make this Sacred Gear was just a common dragon, yet he had to say, it was troublesome to use it, and it was unstable, so he didn't use it.
However, what if he used the ability of this Devil Fruit?
As expected, everything became smooth, and he could easily control Twice Critical.
Then, as he used the ability of this Sacred Gear, he could feel his power had doubled.
Yes, double.
This was the ability of Twice Critical to double the power of the user.
It was a simple ability, but it was perfect for him, especially when his power was monstrous.
Riser was different from Issei, whose power was zero.
Still, it made him wonder whether he should take the "Boosted Gear" from Issei.
Yet, he decided not to as it was quite troublesome, especially when there was Sirzech, so he thought to target the other Longinus or Sacred Gears.
So, after this ceremony, she went to the human world to search for the most suitable Sacred Gear for him by using "Location."
"Onii-sama, here you are. Everyone is looking for you, you know?"
Riser didn't need to turn to guess whose voice it was as he was extremely familiar with this voice.
Ravel sounded so helpless as she approached Riser, but this was a rare chance for them to be alone, so she didn't forget to close the door beforehand.
However, the one who made the first move wasn't her, but him.
Riser hugged her in his arms as he gazed at the distant scenery. Still, unlike before, when she was in his arms, it felt so relaxing and at ease. The warmth of her body and her honey-like scent. Everything about her was just perfect. It felt like he didn't need anything as long as he had her.
"O-Onii-sama..." Ravel was quite embarrassed when he hugged her suddenly.
"What's wrong, Ravel?" He asked as he buried his face in her soft, blonde hair.
"Nothing. It's just... how to say, it feels nice."
While she lost her calm at first, she also felt happy and felt everything was vibrant with him by her side. It felt like the color of everything had become wonderful.
Only the two of them, side by side, without anyone else.
The two enjoyed their quiet moment together before Ravel suddenly said, "Onii-sama, what if... ah, no, please forget what I am about to say." She felt that she shouldn't say this, yet she just couldn't help it as she couldn't help but imagine such a future.
"Tell me."
"Ge-Geez..."
When her neck was kissed by him, it caused her face to flush red, and she let out a sexy moan. While it felt good, she knew this wasn't the time for them to do this, especially when he was about to have her ceremony to become the "Ultimate-Class Devil."
Suddenly, she realized how bold her action had been previously during his "Rating Game" with Tannin, but he wouldn't stop unless she told him, so she could only give up and tell him what she thought in her mind.
"What if... what if we just leave everything behind and live with the two of us somewhere in a place where no one knows?"
"....."
Riser fell in silence and laid his chin on her head, hugging her in his arms.
"...I-I am sorry for saying that."
Ravel quickly apologized as she thought she had made him angry.
"It's okay. I am not angry. However, there is no doubt such a life will be comfortable. Just the two of us, without anyone knowing us. I just can't help but imagine such a peaceful life, but... you should know my personality, right?"
"Yes."
"To live in fear of pursuers, constantly looking over my back without any tranquility or peace, I had rather die while facing my opponents, bringing them with me to the abyss."
While men move based on their logic, women move based on their emotions.
Facing him, who seemed to be exhausted and in pain every time, Ravel couldn't help but wish to be his help, but she couldn't, so in the end, she suggested for them to leave together, on the place where no one knew, having their peaceful life together.
Yet, there was no way for Riser to leave or escape from everything.
"You're so stubborn, Onii-sama." Ravel sighed helplessly.
"I am sorry."
"Don't apologize, Onii-sama. This is also part of you that Ravel loves, so just be bold like before since Ravel will be with you, and Ravel also apologizes for making such a suggestion."
Unlike before, when his mind was tense due to his fight, Riser couldn't blame Ravel since he knew he still owed her a lot, especially when he had decided to make her his woman, even though he knew when their relationship was doomed.
"However, after this, do you want to take a trip?"
"Trip?"
"Yeah, only the two of us, on the place where no one knows."
"That will be wonderful~! Where are we going?"
Ravel was excited about the idea.
"Let's go to the human world. There are many things there."
"Okay."
Ravel agreed without hesitation, especially when she knew no one knew about them in the human world.
Only as the two talked intimately did the door open suddenly.
"Ravel, did you find—"
"....." Ravel and Riser.
