Chapter 14: Best reward

The three magic that he wanted them to learn were, without a doubt, fire magic.

All of them were also his servants, and as his servants, without a doubt, their best magic was either fire magic or wind magic.

As he received fire manipulation mastery, he could teach everything that was related to fire.

Whether it was Phenex ability, ordinary fire magic, fire-related Norse Magic, esper fire-related ability, or any other abilities and skills, as long as it was related to fire, he knew all of them.

When he claimed he was number two in fire manipulation, no one dared to claim they were number one.

While the three magics he wanted them to learn were the same fire magic, each had a different effect.

The first one was fire magic which was related to a movement.

By using fire magic, one's speed would increase dramatically enough to seemingly cause one's body to "disappear."

This magic was simple, and all of them could learn it easily, but it wasn't easy to master it as a movement wasn't just simply charging forward like a boar.

The change of direction, obstacles, and various other things.

One needs to think about all of that before one can master this fire-movement magic.

However, this was good enough for them to run away.

If they wanted to run away, no one should be able to stop them. Naturally, it was only among their levels and slightly above them, but in cases like the big boss like Sirzech, they died.

Though, this single magic was enough to excite all of them.

Still, this was too early for them to feel excited.

The second magic that he wanted to teach them was a heat sight.

Similar to the first magic, it also supported magic, but it was for eyesight. While there wasn't much effect, it helped them to see people through their bodies' heat. Even if there was an obstacle that made them unable to see their targets, their targets were hiding, or had the ability to hide their presence, they could see them with this heat sight.

Now, the last one is still similar.

It was still supplementary magic.

However, unlike before, when he taught them the last magic, their excitement was even better.

"Now, see my body."

Suddenly, his body disappeared, and no one could see his figure.

"!!!"

Then when he appeared again, he smiled and said, "Now, this is the last magic you are going to learn. You must learn it, okay?"

"Yes!"

This time, everyone answered with an even louder voice.

By using fire magic to turn invisible.

He hid his figure by refracting light from the heat, turning invisible. Still, if it was learned even further, it could create a mirage. It was like what he had done before, creating a lot of copies during his previous fight, causing Issei Hyoudou to be unable to find his figures.

Among all the three magics that he taught them, without a doubt, the last one was their favorite, so they learned it well with all of their might.

Moreover, as a devil, who didn't want to become stronger?

Lastly, their master was gentle and supportive, yet also rough; all of them loved him deeply now!

Frankly, a master like him, Rias, or even Sona was rare among the devils.

The majority of the devils treat their servants like slaves.

Evil, wicked, brutal, rotten, scum, wrong, brute, and vicious.

He was sure that most of the devils had at least one of the traits he mentioned above.

"But Riser-sama, is it really alright for us to learn these magics? Aren't they important? Also, while I don't think anyone will spread your magic somewhere since I will kill anyone who does so, don't you feel worried about this?"

Yubelluna, his "Queen," a mature woman with long, wavy purple hair, took the initiative to say so.

Hearing those words, they also realized how serious this situation was and waited for his answer.

Still, as Yubelluna said, if someone dared to betray Riser, then they would kill them.

There was no mercy.

While in the human world, a human might go to prison when they commit a crime, the reincarnated devil doesn't have such a luxury. Once they had betrayed their master, death was their only destination.

"It's okay. I believe in all of you."

Still, hearing such a question, Riser was nonchalant since he trusted all of them. "Still, if my answer might not satisfy you, then the real reason why I am okay with it is that I am strong. With my strength, even if all of you or other people learn those three magic, I don't think someone can defeat me. Though, I would appreciate it if you don't teach this knowledge without my permission since if you do so, you will lose my trust."

"Yes."

All of them answered at the same time and thought that he was handsome.

Strong.

As they had been by his side all the time, they understood he was powerful, especially in his last fight with Sekiryuutei; he showed all of them his real might.

Yet, they also knew that he was correct.

Even if someone learned the three magics taught by Riser, it didn't mean that they could defeat him.

It might sound arrogant, but for someone who learned from him, he had thought of them as his opponent.

Especially when it came to fire manipulation.

However, the most important point, they didn't want to lose his trust, so they had to keep everything in their hearts.

"Okay, how about we start now? The faster you learn, the faster you leave this place."

"Yes!"

What he wanted them was to learn only the basics, so it shouldn't take much time.

As for mastering those three magics, they would take quite a while to do it.

Nevertheless, all of them competed with each other since, as he told them before, the first one would receive the reward.

Yet, when it came to magic, Yubelluna had more advantage over others as she was his Queen, and her talent for magic was better than others.

Riser also wasn't surprised by this since he knew the talent of his Queen well. Frankly, he wondered how this woman could fall on the original Riser, but it didn't matter since she was his now.

Frankly, the power of his peerage members wasn't bad at all, or rather, they were better than Sona Sitri, who often appeared in the story than the original Riser.

As for Rias?

The world seemed to love her, and her luck was so great that she could get her hands on various powerful beings such as Sekiryuutei, the daughter of the general of a fallen angel, a knight with unique Sacred Gear, a powerful healer, a powerful dhampir with Sacred Gear, a rare monster race Nekomata, and also a powerful female Valkyrie.

Moreover, her older brother was Maou, with many powerful peerage members.

While Rias might be a devil, he felt that this young woman was the daughter of heaven.

'Well, in her case, should she be called the daughter of the underworld?'

However, their relationship was far from good now, and the best way for him currently was to avoid her, living away from the plot, so he wouldn't be involved in various troubles unless his strength was strong enough to fight fate.

Still, as he taught all of them carefully, the one who learned the three magics first wasn't Yubelluna, but his little sister, Ravel.

"Onii-sama, I have learned all of them!"

Ravel was happy.

"Good job, Ravel."

He gently stroked Ravel's golden hair with a soft smile, causing her to close her eyes in enjoyment since his patting felt so pleasant and comfortable. Because of this, she wanted to move closer, pressing her body against his, yet she endured it since she was in front of everyone.

While the rest were disappointed, they accepted it and felt it was normal for Ravel to master those three magic first, considering Ravel was part of the Phenex House. Moreover, even if they felt disappointed, what could they do? Ravel was, after all, Riser's little sister.

"Then, Onii-sama, since I am the first one who learned those magics, I can get a reward from you, right?"

Showing her mischievous smile, Ravel asked him that question.

"...."

[Reward? Good, you will give Ravel a reward, but before that, you bring her to your room without anyone knowing and lock the door, then open your pants, giving her the best reward that she will think of in her life]

"....."

Riser decided not to read the system reminder anymore for now.

"So, is there something that you want, Ravel?"

"Um..." Ravel was a bit nervous, and her face flushed red.

"...."

Riser fell in silence and shook his inner doubt, thinking that it should be a normal reaction, or did his little sister catch a cold?

Then, he might as well check her condition, but—

"Ca-Can we go out together?"

".........."

---

".........."

Cough!

Still, I have to say that Riser's servants aren't that strong, but isn't it normal? Not everyone is like Rias, whose luck is against the sky. However, they should have potential. After all, even Sona's servants (except for Saji and Tsubaki Shinra), that don't have much potential, can become strong, so why shouldn't Riser's servants can't do so?

By the way, can you give me advice on what kind of rewards he should have in the future?
