Teaching Irina and Xenovia

It was morning, under a blue sky with few clouds and birds chirping not far from the housing estate.

Last night, Eiji did not really bring Eriri to the hotel. What he told Tomoya was just to stimulate the protagonist to the point of vomiting blood and fainting. After being satisfied with the blowjob service, Eiji wanted more, and actually Eriri, who was horny at the time, was also not difficult to persuade.

It's just that at that time Eriri's cell phone rang, Eriri's mother contacted her daughter who still hadn't come home after more than 7 pm. Eiji remembered in the original work Eriri's mother had an almost similar appearance to Eriri except she chose black hair tied twintail style and a slender figure that could be considered beautiful. Ahem! That's it, he was in no hurry to eat meat, he also understood the worries of a mother worrying about her daughter. So with his magic, he immediately escorted Eriri back to her home.

Unlike before, the girl looked at him differently. There was tenderness behind her tsundere face. It was an expression that Eriri had previously only given to the protagonist Tomoya and now it belonged to her. In the process of slapping Tomoya last night, Eriri said she was his girlfriend. Eiji didn't deny that, nor did he ask about what their relationship was now.

--

Those things let Eriri decide for herself. Anyway, I'm sure that girl will think of me more often instead of her childhood friend. After tasting my little brother, she must be addicted and will take the initiative to come to me.

--

It wasn't that Eiji didn't want to take the initiative, but there were also other heroines still waiting for him at home and other heroines out there. As a harem protagonist whose harem had grown to the point where he was having trouble dividing his time for his women.

Eiji was only one person and one body, he could not give too much time to just one woman.

"I'm a busy man..." Eiji muttered with the katana in his hand. In the spacious backyard of his house like a meadow that was 200 meters wide after being expanded with Lala's technology. For your information, this technology was like the one Lala used to expand every room in his house.

Although it did not look so spacious on the outside, only when one entered the gate of his house would one know how spacious the Eiji Seiya Residence was... Actually at this point should he call it the Seiya Family Residence? After all besides him, there were many beautiful women living in his house and all of them were his women.

Tearju, Momo and Nana were the exceptions. But it was only a matter of time before those three women joined his extended family. Eiji immediately cleared all the dirty thoughts in his head. Holding tightly the katana he created with his creation magic, it was just an ordinary katana, a Japanese sword that had a long, slender, and sharp blade.

In a plain white T-shirt and black sweatpants, Eiji stood with his breathing sounding loud. There was visible steam coming out of his mouth. While bending his knees, shifting his right leg back and left leg forward, the posture of holding his sword was also emphasized on the right side of his waist. Like a samurai about to draw his sword.

In front of her, 30 meters away, were 25 humanoid figures also created by Lala. They were called MicroBot-Kun, even if destroyed many times, they could repair themselves indefinitely as long as the core in Lala's hands was not destroyed. However, if Eiji was serious, he could certainly eliminate all the robots completely. But now he had no intention of doing so, he would just display what the breathing technique he got from the system was like and let the girls who were watching on the side know.

"Thunderclap Breathing."

"First Form - Thunderclap and Flash."

Instantly, Eiji's body was enveloped in yellow lightning, his figure also moved very fast, very fast like a thunderous lightning strike. In just a second, Eiji's position had moved behind all the robots with the same posture but there was a click of the katana being put back into the sheath even though they didn't even know when Eiji actually drew his sword.

They only caught a glimpse of yellow light moving in a straight line and...

Boom!

They also saw all the robot heads severed with a yellow lightning strike effect and exploded.

All the robots were destroyed before repairing themselves after a few seconds. But that's not the point! The point now was that Xenovia and Irina's eyes lit up.

"So that's the kind of breathing technique Eiji-sama is referring to? Very cool! I want to learn it too!" Xenovia said excitedly, Eiji's figure also suddenly appeared in front of her and Irina and patted her head.

"Sure, I'll teach you. But unlike me, not all breathing styles are suitable for you. So you have to choose one."

Before this, Eiji had actually discussed the Breathing Techniques of the Demon Slayer franchise with Xenovia and Irina. Unlike his other girls, the two girls specialized in swordsmanship because they had previously been trained as Holy Sword users by the Church.

So things about breathing techniques would actually be very suitable for them. As for the other girls? Rias, Sona, Akeno, Grayfia, and Kuroka did not use swords. They weren't interested in learning breathing techniques. Eiji also didn't force them and focused on those who were interested. Lala too, sword techniques were also not suitable for her. Run, Yui, Haruna, and Mai were the same. For those girls, Eiji thought of looking for something more practical to increase their power.

For example like the Devil Fruit from One Piece, unfortunately he only had one. Eiji still had to do more quests and hope Miss System gave him more Devil Fruits or similar rewards that could be given to others. After all, the stronger the girls themselves were, the better so they could protect themselves.

"Then what breathing technique is most suitable for me, Eiji-sama? What about the lightning breathing style you used before?" Xenovia asked, actually after seeing the lightning style Eiji used, she also wanted to learn that one.

"Me too! Eiji-sama, can I learn the lightning style breathing technique?" Irina also thought like Xenovia, she was also more interested in the lightning style.

She could imagine when using her Excalibur Mimic, the sword was enveloped in lightning, she could move very fast, and slaughter her enemies in one second just like Eiji did.

Xenovia imagined her Durandal enveloped in lightning and she liked it just because it looked cool and powerful.

Eiji's lips twitched. Obviously he had told the two girls all the different types of breathing styles. They had many choices, but they seemed to really want to learn the lightning style. Unfortunately unlike him who cheated by being able to use all the breathing styles, it was very difficult for others to do the same.

In his case, he instantly learned all the breathing styles because the system directly fed the experience of how to use all the techniques directly into his brain. With Anos's magic being able to send what she knew directly into other people's brains. A kind of memory transfer magic, Eiji could also actually transfer what he knew to the two girls.

But to learn breathing techniques from that franchise. One must also have a talent and body match for the breathing style one wanted to learn. For girls like Irina and Xenovia...

Eiji glanced at the two, he stopped patting Xenovia's head which made the girl look at him with some reluctance. Holding his chin and looking at the girl and Irina, he looked them up and down.

Xenovia and Irina were both wearing sportswear like him. However, those clothes could not hide their curvaceous and sexy figures.

The two girls were also now living in his house since they returned from the mission.

Eiji sighed.

"E-Eiji-sama, what's wrong? Are you thirsty? If you want it... I actually don't mind to..." Irina's face reddened, she seemed to misunderstand Eiji's gaze which stared at her and Xenovia's bodies without blinking.

Xenovia tilted her head in confusion. But she also immediately misunderstood like Irina, she looked at Eiji and said: "Eiji-sama, should I strip myself?"

"No, Xenovia. What are you suddenly talking about? You too Irina, you two misunderstood... I'm just seeing what breathing style best suits your physique." Eiji wondered what his image was like in the minds of the two girls? Did they think he was a beast who lusted all day at the sight of beautiful girls?

¶{You don't?}

"....."

Miss System... Of course not. At least your host knows how to restrain himself.

Eiji's smile was almost broken, especially seeing Irina and Xenovia's gazes that didn't quite believe what he said.

He pretended to cough and put on a serious expression.

"Irina."

"Yes!" Irina unconsciously straightened her body and replied. She wondered which breathing style was suitable for her? Could Eiji really know what suited her best just from looking at her body for a few seconds?

"I've seen your swordsmanship focuses on speed and agility. The sword you're using is also..."

"Excalibur Mimic." Irina reminded him of the name of her sword. Eiji suddenly thought of a certain sword name called "Chunchunmaru", making him almost laugh.

Geez, he nodded. "Yes, your Excalibur Mimic is also the type of long, slender sword that has the ability to change shape into any weapon. With your physique being more flexible and agile than Xenovia's. I feel that instead of the lightning style, you are more suited to the more flexible water style."

[Water-style breathing technique. This is actually the same breathing technique used by the protagonist of the franchise where this technique originated. Water Breathing is a breathing technique that mimics water, specifically the flow, flexibility, and adaptability of liquid and replicates it with the user's movements, techniques, and abilities. Most, if not all, known techniques involve their users bending their bodies, arms, and weapons in a flowing motion to match the movement of rushing or flowing water. Users also visualize themselves as if creating and manipulating water when unleashing the technique.]

[In addition to being powerful, this technique is also no less cool than the lightning style. In my opinion, Irina has high compatibility with this technique.]

Irina was initially disappointed to hear that the style that suited her was the water style because it was water, wasn't it wet and weak? It's water after all. But after hearing it was the same technique the protagonist used, it was strong and no less cool than the lightning style. Irina was happy, she was excited to learn the water style breathing technique.

"Water style? Okay Eiji-sama! Please teach me!" Irina raised her fists with excitement on her beautiful face.

Eiji did not disappoint her, he raised one of his hands, and extended his index finger on the girl's forehead. "Teles", this was Anos' magic spell that had the function of transferring the user's memory or knowledge to another person.

The process was painful, but as a former exorcist Irina's pain resistance was quite strong. She only frowned during the process which lasted for 5 seconds. After that, she let out a sigh of relief and took out her Excalibur Mimic out of nowhere.

"I've transferred how to use the water breathing techniques directly into your brain, Irina. But you still have to practice to get your body used to using those techniques."

"Water breathing has 11 techniques that each have their own advantages and disadvantages. But as long as you are able to switch from technique to technique in every battle situation and combine those techniques with your Excalibur Mimic magic and power..."

"You will be much stronger than the current version of yourself."

"So go train with those robots."

Eiji pointed to the training robots ready to be harassed by Irina, the number could even be increased, up to a maximum of 200.

Irina obeyed what Eiji said, she immediately ran towards a group of white robots that also had the ability to attack and dodge. When using a sword, the robots were also able to create swords and attack her from various directions.

Even so, Irina did not panic. She smiled and performed a circular slash, her slash creating a very sharp high-pressure water. Actually unlike water magic, the visual effect of the water style breathing technique was also exaggerated to the point that the girl was very keen on trying other water breathing techniques. She seemed to struggle at first, but quickly got used to it.

Eiji looked satisfied to see Irina, the girl's sword talent was actually good so she had no trouble adapting to water breathing.

The moment his attention was distracted by Irina, a soft and rubbery sensation pressed against his chest.

"Eiji-sama, Eiji-sama, when is my turn? I also want a sword technique that is not inferior to Irina!"

Xenovia pointed at Irina enviously, she also seemed to be unintentionally using a flirtatious posture without realizing how dangerous her trained body was to a man.

Fortunately Eiji's little brother was content these days, he wasn't so hungry now. So Eiji looked at the blue-haired girl lightly and pinched her cheek.

"Eijwi-suama?"

"Okay let go of me first. I will immediately transfer the breathing technique that suits you." Eiji said.

Xenovia released her bear hug on Eiji, she let Eiji's index finger press against her forehead. She frowned, but just like Irina, her pain resistance was also quite strong.

Processing the information inside her head, she looked at Eiji with a frown.

"What? Don't look at me like that... Are you dissatisfied?" Eiji looked at the girl with a funny look.

"That... Can't I really try other breathing techniques, Eiji-sama? It's not that I'm not happy, it's just that the stone style is a bit..." Xenovia lowered her head slightly, she was actually disappointed with the breathing technique she got.

Of all the breaths, she got the stone breath which didn't have much visual effect like the water breath Irina had.

"Silly girl, don't just look at the visual effects of that technique. Actually, the stone style is no less powerful than the water style."

"Really? How strong can it be?" Xenovia looked at Eiji curiously.

Eiji remembered his original work. Stone breathing, water breathing and even other breathing styles were actually nothing compared to the magic in this world. After all it was just a technique, and in his opinion the level of the Demon Slayer world itself was still below Highschool DxD. But that didn't mean breathing techniques couldn't make people stronger. The people in Demon Slayer only relied on techniques and their bodies to fight, but in this world...

There was Sacred Gear and magic items like the Excalibur fragments that Irina and Xenovia had. The latter not only had Excalibur Destruction, she also had Durandal in her pocket. There was also the magic power that both girls possessed. So the potential of the breathing technique could be improved even further from the original work.

"Xenovia. Unlike Irina, the swordsmanship you use is two-handed swordsmanship, right? It focuses on strength and defense. The sword you use is also a big and long type of sword."

"Yes Eiji-sama. By the way the names are Excalibur Destruction and Durandal, Eiji-sama." Xenovia said.

"I know." Eiji looked at the blue-haired girl flatly.

[Isn't that just the name of the sword? I'm just too lazy to call it. Why do you and Irina emphasize your sword names so much?!]

Irina who was busy trying out the ninth form of water-style breathing giggled at this.

Xenovia took out Durandal from the small dimension that opened beside her. The sword was dark blue in color with golden stripes on the corners of the blade. There were several chains binding the sword, but all of them were automatically released when Xenovia grasped it.

She stuck the sword into the ground with a proud expression on her face. Having long since stopped being an exorcist and left the Church, she and even Irina had no intention of returning the swords to the Church. Until now, the Church had also remained silent on this matter which made them comfortable.

Xenovia did not know whether what she was thinking was flying a certain flag or not.

"That's why I think stone breathing is more suitable for you. This technique also prioritizes the user's strength and defense. For example, once you master and adapt to stone breathing."

"Even without releasing the holy power of your Durandal, your slashes will be stronger to cut through anything. Your defenses will also be harder to penetrate. Compared to the visual effects of Irina's water style, the benefits one's body gains from the stone style actually more favorable."

[If the stone breathing technique is improved even further from the original work. As long as Xenovia can do it. A sword slash, with just technique and pure physical strength, that girl should be able to cut a small mountain in half.]

"I... I understand Eiji-sama! Thank you! I will definitely not let you down, I will master stone breathing and become a stronger sword for you!"

Xenovia's eyes looked very excited, there was an illusion of fire in them. The girl seemed to have imagined how she would cut through one of the mountains in Japan with her sword.

Seeing that the girl had already run to the other side of the courtyard next to Irina and ordered more robots to fight with her.

Eiji smiled wryly. "Finally finished..."

What exactly was he teaching the two girls breathing techniques for? Aside from increasing strength so that they could protect themselves better. He also gave the technique as a reward to the two of them for completing his mission.

It was only given on his initiative, if the girls still wanted something. Eiji would certainly not be stingy and let them ask him for the reward they wanted.

"Eiji-sama, want a drink?"

Grayfia's beautiful voice was heard, the silver-haired maid had also been watching from earlier. It was just that she chose a suitable time to appear and did not forget to bring a glass of cold lemon juice for him.

"Thank you Grayfia." Eiji took a glass of juice from the tray the woman had brought. He drank it and felt very refreshed. Seeing Grayfia in her usual maid uniform didn't help either, his eyes lit up when he saw that figure, he never got tired of seeing her.

Grayfia was not bothered by Eiji's gradually heated gaze as he stared at her, she even raised her chest deliberately before saying: "Eiji-sama, I have something to say to you."

"Hm? What is it?" Eiji looked at Grayfia who was standing beside him curiously while ignoring the several explosions Irina and Xenovia were making.

"Yesterday when you came home late from school. Actually a woman in witch clothes came to the house to meet you."

"Then?"

"Because you weren't home and were still busy playing outside. She left and said she'll be back tomorrow."

"Meaning today?"

"Yes." Grayfia said as she picked up the glass whose water Eiji had emptied.

Eiji tilted his head. "Isn't that Serafall?"

"That woman looks like a beautiful blonde witch with a pointed witch hat. Not a magical girl."

[That's your way of saying that woman isn't Serafall? Grayfia, you're not wrong. I understand.]

[But still... A beautiful blonde witch? In the original work, a woman with this kind of appearance should only be able to be...]

Ding dong~

At this moment, the doorbell of the house rang.
