Sona appeared worried, but he calmed her down. The girl told him that they had contacted Azazel, the leader of an organization called Grigori, and that the fallen angels, who formed part of Grigori, had left Kuoh. Apparently, without meaning to, he had stopped a war.
When her mood calmed, she returned to treating him with a certain coldness. She handed him a folder containing the results of the Phoenix dust tests.
The girl stated that the most significant amount they had ever used was three hundred grams, which was used on Sairaorg Bael, who, according to the girl, was one of the strongest devils; however, there were stronger devils, such as the Maou. That was a relatively large amount to ingest, but since it was not a standard drug that needed to be absorbed and enter the bloodstream, it was acceptable. And the devils' bodies can withstand it quite well.
She also told him that some of those who took it described it as the most magnificent thing they had ever tasted.
Altair knew what they were talking about. It was delicious. No matter what potion was used to dilute it, it always tasted the same. It wasn't something he had ever tasted before; he couldn't compare it to any food. Lily said that somehow it reminded her of the feeling she got when she heard a phoenix sing.
Sona divided the doses into four types. She generalized the low-class devils, who ingested two grams for an effective dose. Mid-class needed fifteen grams, and high-class needed around thirty to fifty grams.
Older physiques require trial and error.
Sona ordered one hundred kilograms.
Although she admitted, with flushed cheeks, that some of it would be sold as an exotic food. Even her father wanted to eat it for dessert. Altair asked her to divide the purchases between the two uses. He said he would sell it for both purposes, but that it would be cheaper as medicine. He also said he will modify the taste so that patients will not become addicted.
And they won't be able to buy it as medicine and use it as a luxury item.
The girl agreed. She took the three hundred and sixty kilograms that Altair put in an expandable bag. The payment would be a territory in the underworld and the construction of a mansion on it. He didn't know how often he would use it. But it didn't hurt to have a place there.
She sent him more books on magic, not only devil magic but also some by wizards who had given them to her as payment for a contract.
Altair was surprised to see a book by Rowena Ravenclaw. He didn't wait to read it.
He spent the rest of the afternoon creating more phoenix dust and reading the book by the creator of his house.
Later, after spending some time in his Phoenix Dust factory, he walked back to his room. Lavender told him that the girls were having a sleepover with Asia, something like a welcome to the coven. The girl barely understood, even after Lily used the translation spell on her.
Lily herself told him that Asia had magical potential. So she could assist Hogwarts.
She used a power-measuring orb. [5,342] was a reasonably high result for the nun, above the magical average for her age.
He still hadn't discovered what kind of Sacred Gear she had, although he didn't have much hope. It would probably be a common one; otherwise, the church wouldn't have expelled her so easily.
"Mr. Black," he heard a strict voice in his room.
His quarters had been decorated. It looked more like a school classroom than a bedroom. There was a blackboard and a desk with "Himejima-sensei" written on it.
The woman who spoke to him was standing in front of him. She was wearing a pencil skirt and a white shirt that was definitely not her size.
"Eyes forward," he heard another voice, this time from Rias.
The girl was dressed the same, except her shirt was a different color. Her blue eyes were hidden behind round glasses.
"Believe me, professor, they're in front of me," he said, looking at the girl's bare legs.
'Grayfia isn't going to jump out of hiding at some point, is she?' he thought, not wanting to end up with blue balls. Again.
"Take a seat, Mr. Black," Akeno returned, tapping a huge ruler in her hand. "Remember what topic we're discussing today?" the teacher asked.
"And remember to call us 'sensei,'" added the redhead. Nodding, she took a seat. "We only brought one chair," she whispered when she saw Akeno standing.
"My face is available," joked the boy. "We were going to talk about Sacred Gears," he said. Not because it was dense, but it wouldn't hurt to take advantage of it.
He looked at the two girls, who were staring at each other, their eyes trembling.
"Really?"
"Yes," he said.
Akeno looked at him with narrowed eyes. However, the corners of her lips betrayed her amusement.
Rias couldn't hide her disappointment. She lay down on the table.
Slap!
Akeno's ruler hit the desk.
"Despite my better judgment, I accepted your help, Gremory-sensei. Don't make me regret it," she warned.
The crimson-haired girl looked at her in surprise. Her queen had never spoken to her so harshly before.
"What is a Sacred Gear?" Altair asked.
"Sacred Gears are artifacts created by HIM," Akeno rolled her eyes. "They confer abilities on their owners, who are mostly human. Or hybrids," she bit her cheek.
"What is a balance breaker?"
"It's a state of the Sacred Gear. It unleashes the artifact's full potential, granting new abilities and enhancing existing ones. Himejima-sensei didn't say it, but the Sacred Gear usually has a physical representation. The balance breaker also affects that appearance," Rias explained reluctantly as she watched Akeno raise the ruler.
"And anyone can unlock them?" He hoped Asia would make it.
"Theoretically, yes," Akeno replied. "It requires training and facing some emotional trauma."
"What about the Longinus?"
"They are the strongest," Akeno seemed to be getting annoyed, but she continued explaining, "There are only thirteen of them. They were the originals, the first to be created. They are Sacred Gears with the ability to kill gods."
"So God exists?" That was an absurd question, meant only to annoy.
"Enough!" roared the devil, seeming to feel a pang of pain at hearing the name. "Rias, stand up," she said to her king. Although at that moment she was just a colleague. "You're going to punish him for his recklessness," Akeno directed her.
"Punish him?" The crimson princess stood up. "Ouch! Akeno!"
"Himejima-senpai," she corrected her, whipping her ass with the ruler. She was clearly enjoying this. "It's punishment for both of you. Neither of you takes education seriously," she seemed genuinely angry.
She took a piece of chalk and wrote on the blackboard.
'Sexual education'
"This is my area of expertise," she said and looked at both of them.
"Akeno... you're a virgin," said Rias. "Ouch!" She rubbed her butt again.
Altair was a little surprised to hear that, but when he saw the devil girl's blushing face, he knew it was true.
Akeno, or Himejima-sensei, continued writing on the blackboard.
1.- Nudity
2.- Masturbation
3.- Paizuru
4.- Blowjob
5.- Breast sucking
6.- Cunnilingus
7.- Vaginal sex
8.- Anal sex
9.- Creampie
10Facial
"That will be the content of our class," said Akeno. "Gremory-sensei has joined us as a test dummy for you to practice on, Altair-kun."
"Wait... WHAT!?" Rias was supposed to just be there to watch. "Akeno!" she squealed as her best friend released her enormous breasts from her shirt.
A red bra struggled to contain them.
"Hi-me-ji-ma-Sen-sei," Akeno squeezed her breasts as she spelled out her name. "Tell me, Altair-kun, do you know how to remove a bra?" she asked.
"I can make them disappear," he said enthusiastically. He stood up and walked toward the blackboard.
His hand reached out with the intention of touching Rias' breasts. Instead, he ended up stopping the ruler that was about to hit the back of his hand. He looked at Akeno with raised eyebrows.
"Iaa!" Rias fell/threw herself forward.
Altair stopped her by holding her breasts with his hands. The girl let out a scream that was half horror, half pleasure.
"Abracadabra!" he said. Soon his hands touched the girl's bare breasts. The red bra was stored in his inventory.
"I don't remember giving you permission to touch my assistant," Himejima-sensei pulled Rias back.
Altair watched the pink nipples sway like two tiny boats on the sea, rising and falling intermittently until they stabilized.
"She fell, I just held her up," he excused himself vaguely.
Akeno dragged the teacher's chair over. It was leather, comfortable unlike the wooden desk he had been forced to sit at earlier. She pressed a button and the chair turned into a large bed.
"It doesn't matter. Since you decided to break the rules, I will too," she took the chalk and underlined points five and six.
5. Sucking breasts
6. Cunnilingus
"We'll start with those points. Since you gave my classmate a hard time," Akeno said thundering the ruler in her hand. A dull sound filled the room. "You owe her compensation..." she said, referring to the bet they made the day before.
"Oh, Satan," said Rias, looking at the two points.
