Can you teach me, Sensei?

[Congratulations, you have received "Archive" magic]

"...."

When Aika fell asleep, Riser didn't expect that the system would really reward him. He looked at his first client, who was sleeping, wondering whether she was part of an important character in the story.

After all, that was how it would usually be.

When he had taken down an important character in the story, the system would give him a better reward.

If he gave an example, it was Sona and Akeno who gave him a rich reward.

If he gave another example, it was like his peerage members, who didn't give him much even though their numbers were superior to Sona and Akeno.

Nevertheless, while Aika's position in the story might not be that much more important than Sona and Akeno's, she should have a certain role in this world even though it wasn't much.

The proof?

It was his reward.

Archive.

It was a rare magic to transfer information to and from people for various purposes.

With this, he was capable of coordinating the movements of his allies as well as knowing their present conditions and giving them new knowledge.

That explanation might be hard to understand, but this magic was like a computer.

He could transfer data to another, talk with each other, gain access to stored information, and convert information into magical data.

Frankly, this magic might not have much power.

No, it might even be useless when used in battle, but for support or even leadership.

It was terrific magic.

If he gave an example, if he wanted to teach his peerage members magic, he could transfer the information of that magic into the head of his peerage members like he transferred data to a hard disk on the computer.

It was practical, right?

In other words, there was no need for a long explanation as everything could be transferred into their heads directly, like data, and that data was implemented into their minds so they would remember it forever.

Still, it was also due to this function he tried to use this magic directly.

As he used this magic, he saw several flat screens projected into the air.

He knocked on the flat screen and felt that it was pretty durable, so it could be used as a shield.

Still, he quickly turned off the magic as he looked at Aika, who was sleeping by his side.

As he observed her, he put his palm into his nose and smelled a distinct scent of her body.

Every girl had their own scent, and each of them was special.

Still, he had to say, he was really a devil.

Nevertheless, with this, his first job ended with success, and he returned to his wife as if nothing had happened. Naturally, he didn't forget to burn Aika's scent on his body since explaining what kind of request Aika had made for him would be troublesome.

After his first client, his days had been peaceful for several days.

Rias and Sona also sent some of their peerage members to help the two exorcists retrieve the stolen Excalibur. Nevertheless, the result was still disappointing, and it might take a while for them to retrieve the legendary Holy Sword.

However, while their peerage members were working hard, Riser spent his days quite splendidly.

From night to morning, he would spend his time with Sona.

When school ended, he would spend his time with Akeno.

Lastly, when he went home from Akeno's place, he would meet with Aika.

It might be strange of him to visit Aika, but then again, she was his first human, so she took quite an important part in his life.

Still, there was no doubt that his life was like a devil should be.

He was living a dirty, debauchery life.

Still, he didn't do a dirty thing all the time since he also made an underground space and training space under Sona's house, managed his business in Tokyo, helped Nurarihyon take care of his problem, and trained his muscles.

Yes, muscles.

While his physical ability was good, it was still far from the perfect state.

His goal was at least to reach Sairaorg's level.

When he had reached that stage, he felt that it was enough.

Still, unlike his other abilities, it might take a while for him to reach Sairaorg's physical ability after all; unlike the abilities of Phenex and other magic that could be easily learned with talent and high intelligence, the physical ability needed discipline and hard work every single day.

Frankly, when he thought about all of this, he realized that he had started to get far away from his dream of becoming a lazy bum.

After all, what kind of lazy bum worked so hard every day?

However, there was no doubt his days were fulfilling, and in those fulfilling days, he received a call from Magari, the leader of the Nekoshou, who was also the one who trained Ni and Li.

"You are going to leave soon?"

Aika looked at Riser in disbelief. They had only met for a few days, then he would go just like that?

Still, it wasn't like she wasn't prepared for this since she knew that he was married.

Naturally, she was prepared for him to leave her, but then again, deep in her heart, she also expected that he wouldn't leave and stay with her. It was like how the lover of a married man hoped their lover would choose them over their wife.

Aika's current emotions were like that.

"I came to the human world for business. I need to take care of it, so I will leave. You don't need to worry; I will return it when it is over."

Riser, who was reading an ecchi manga, looked at Aika, who was playing with his rod and patted her head gently.

"Really?"

Hearing that, she signed in relief, but she still asked once again to confirm it.

"Yes."

"Wait, where did you live?"

"Underworld."

"...you mean hell?"

"No, it's different. An underworld is the world where the devil and the fallen angel are living. It is like an Earth, but there isn't any ocean there. Try to read Divine Comedy; you will understand better."

Aika realized that her knowledge of the devil was relatively low, and as she had made a devil as a lover, she wished to learn more about the devil.

"Still, do people enter hell?"

"Hmm..." He fell in silence for a moment, then asked, "What religion do you follow?"

"Religion?" Aika fell into silence since it was hard to say what kind of religion she followed.

While she might wish to marry in the church, she also went to the temple or shrine to pray.

However, this was the current situation of most people in this country.

After all, compared to their everyday life, praying was something they would only do when they needed to do something.

"It depends on your religion. If you are Christian, then you will go to hell if you do something bad and go to heaven when you do something good. But if you are a Buddha or Shinto believer, then it will be different."

"Then, have you been to heaven or such a place?" Aika asked.

"Hmm.. my ancestor seems to wish to return to heaven, but if you ask me whether I have gone there or not, then I haven't. As I have said before, you were my first human, and I spent most of my time in the Underworld."

"Now that you mention it, are there so many devils in the human world?"

"It's hard to say. You know, if I make a comparison, it is like a human who only stays in their country all the time instead of going to a foreign land. There are more devils who haven't been in the human world than those who have.

"After all, the human world, or Earth, isn't only a place for the devil, angel, and fallen angel. There are many myths, and all of those beings you think only exist in the fantasy also exist.

"Buddha, Sun Wukong, Dragon, or even a youkai like Nurarihyon, Oni, or even Bakeneko also exists.

"To be honest, I came to the human world due to business cooperation with Nurarihyon."

"Then, isn't this world dangerous?"

If there was such a thing, then wasn't this world a dangerous place?

"Well, if you are not involved in this side of the world, then until you die, you won't be involved, but then again, it isn't like they are that powerful either, so you don't need to worry."

Frankly, those supernatural beings that he had seen in this country were too weak.

Still, he could see that she was still worried, so he asked, "If you are worried, how about I teach you magic?"

"Eh? Can I?" Aika was surprised and eager.

"I can teach you." Riser nodded.

"Then, please teach me, Sensei!"

"Well..." Riser looked at Aika and said in deliberate manner, "That depends on your performance today, though."

"...."

Aika looked at Riser for a moment, then picked up her uniform, wearing them in one go. Her lewd appearance had disappeared, and what was left was an innocent expression that only appeared on a girl around her age.

Yet, while she appeared innocent, she leaned on the wall, showing off her bare buttocks through her short skirt and shiny pink streak.

"Sensei..."

Her voice was meek and seductive. "Can you give me more~?"
