You can only be mine

"It's rare of you to ask me to take care of your hair." 

In Aiz's room, Riveria took care of Aiz's hair carefully and elegantly, suitable for her title as the queen of all elves. While she was surprised, she was also happy, thinking that Aiz had started to think about taking care of her appearance. 

"Um." 

Aiz only lowered her head, feeling a little embarrassed. 

"So, what's wrong? Why so suddenly?" Riveria asked curiously. 

"Um..." Aiz thought for a while, then asked softly, yet with a determined expression, "Do you know how to make a man fall in love?" 

"....." Riveria. 

Meanwhile, as Isao ate breakfast with Hestia, Daphne, and Cassandra, he also talked about his plans to visit the dungeon. 

"Huh? We're going to the dungeon?" 2x

Daphne and Cassandra were dumbfounded. 

"Why were you two surprised?" Isao looked at the two strangely. 

"No, I just thought that we're a business type of Familia..." Daphne said awkwardly, only realizing that they were an exploration type of Familia. Yet, she couldn't be blamed, especially when Isao had entrusted them with many of their Familia businesses. 

Bookstores, publishing, newspapers, machines related to publishing, paper, ink, stationery, mascots, dolls, small toys, and even forests! 

There were many of his ventures, and at this moment, they almost had a monopoly on paper, ink, and stationary, giving them a large amount of a stable income. 

Unlike when they were adventurers, watching such a large amount of money enter their accounts made Daphne and Cassandra feel dizzy, but they also felt excited!

Moreover, Isao had never been stingy with them and often gave him generous rewards, which made them able to buy various clothes or foods. 

Like Isao, their clothes were stylish and never outdated, always appearing elegant yet capable. 

After all, like Isao often said, "people judge a book by its cover." 

If they wanted to be taken seriously, they had to appear the best they could. 

At the same time, they also knew that Isao's business had never stopped, and newspapers, publishing, and bookstores were something they wanted to monopolize next! 

Frankly, compared to fighting in a dangerous place such as Dangeon, following Isao to do business was the best! 

"Having a business is nice and all, but what can you do if you can't protect it?" Isao looked at the two helplessly. "Did you forget about your previous Familia, who had lost to me? In just a single game known as a War Game, all of the efforts that Apollo and his Familia had made over many years disappeared and became mine. 

"In the future, someone might challenge us and, even worse, attack our business due to jealousy. If we don't have the power to protect it, then we're as good as over, so we have to get stronger." 

With the money, Isao could hire someone to work for him and protect his business, but he knew this wasn't a cheap solution. Moreover, it was better to rely on himself instead of others. 

"We understand." 2x

Hearing his words, Daphne and Cassandra nodded obediently. Their memory was still fresh, and they recalled how Isao had slaughtered their Familia. At the same time, instead of being called a traitor, many of their ex-comrades felt jealous of them, who were chosen by Isao, especially when they lived so well. 

To protect their comfortable lives, they had to become stronger. Isao's words were not wrong, so they knew that they had to go to the dungeon. 

"Do you want me to invite more members to our Familia, Isao-kun?" Hestia asked worriedly since she also knew that she was too lazy to search for another member of Familia so they could help Isao. 

"No, it's fine." Isao shook his head. "Instead of a group of small fries, I want a small elite group. Moreover, with how lazy you are, I can imagine that you will complain about updating many Familia members' status." 

"...." 

Hestia realized that Isao understood her well. 

"But is a small group of elites enough to protect our Familia?" Daphne asked with doubt. 

"If all of us become a Level 6 or 7, is there anyone who will challenge us?" Isao asked. 

"....." 3x

His question was simple, but they nodded, thinking that if all of them had become Level 6 or 7, then their Familia would be as good as one of the strongest Familia in the world! 

Even Loki Familia and Freya Familia weren't their opponents, especially when they also had another source of income. 

"So work hard. Try to become a Level 5 as soon as possible." 

"...." 2x

Daphne and Cassandra were speechless since Isao thought that becoming a Level 5 was so easy.

If it was so easy, then why should someone be stuck with a Level 3 or 4 for their entire lives?! 

Still, whether it was Daphne or Cassandra, they were Level 2 adventurers, and they were almost at their limit, so it might not be that long before they reached Level 3. 

As for Isao, when he entered a dungeon, they felt that he would become a Level 3. 

By then, in their Familia, there would be three Level 3 adventurers; by then, they would no longer be a small Familia! 

Hestia was so excited at that moment, but then—

"Hestia, isn't it your time to go on the job?" Isao asked. 

"Ah, right!" Hestia was startled, realizing that she was almost late for work. Even though her Familia didn't lack money, they still had a lot of debt, especially to Hephaestus. Isao could pay it by himself, using his body, but it was impossible for her to rely on Isao all the time, so even if she could only pay the debt slowly, she decided to keep working as a staff at Hephaestus stores and sometimes returned to her old job as stall staff of the Jyagamaru Kun stall. 

Isao also didn't tell her to stop since those jobs could also train Hestia, so she wouldn't be lazy all the time. 

"I will go back as soon as possible! Rest well!" Hestia kissed Isao's cheek, then quickly dashed toward her job. As for Daphne or Cassandra, she didn't think that they would attack Isao, especially when he was hurt. 

"..." Daphne and Cassandra. 

Isao touched his cheek, which was still warm from Hestia's kiss while shaking his head helplessly. "We'll probably go to the dungeon after the Monsterphilia. I will try to make you a weapon, too, before that." 

"Huh? Can you make a weapon, Isao-kun?" 2x

Daphne and Cassandra were dumbfounded. 

"I can." 

"....." 2x

"So, prepare yourselves. I will try to recover as soon as possible." 

"Yes." 2x

Still, as they sat close to him and listened to his instructions about both businesses and their adventurers to the dungeon, they felt distressed as they watched him, who was still working hard even if his hand was torn last night. When they thought of Aiz and Loki Familia, they also felt annoyed and infuriated, but they knew that they weren't their opponents and could only swallow their anger until they became stronger and became his best supporters. 

Nevertheless, when they joined, they thought that Isao would do something lewd and obscene to them, yet unexpectedly, he was a gentleman and even trusted them with many things, but they knew that Isao wasn't a homo, especially when—

"Isao-kun, are you okay?!" 

After a knock in the room and permission to enter, Eina entered his room as she appeared pale and worried. 

"I am fine. I should recover soon." 

"Geez... why didn't you tell me..." Eina was at a loss when she knew that Isao was hurt, but more importantly, when she heard the reason why he was injured from Hestia, she was just... helpless as she could do nothing to help him. 

As the two talked, Daphne and Cassandra weren't ignored by Isao, and Eina also greeted them. But then, their eyes narrowed at Eina before turning normal, and they walked away, as they still had many jobs that Isao had entrusted to them, especially when he was hurt. 

"Daphne-chan..."

"I know, Cassandra, but we're from the same Familia as him, and he should be with someone from the same Familia." 

Instead, with an outsider, Isao had to be with someone from the same Familia. 

As their thoughts were the same, their faces flushed red, but they weren't in a hurry, especially when they would be with him for a long time. 

Still, when they left, Eina couldn't control herself and started to make out with Isao. The two kissed each other while she was still dressed in her guild staff uniform. While he wanted to rub her buttocks that were tightly wrapped in black trousers, his hands were still wrapped, so he couldn't do anything and was helpless against her advance, but then, suddenly, the door was opened. 

Everyone was startled, but Isao was annoyed and looked at the culprit, who had interrupted him and Eina. 

"...Aiz?" 

"Wallenstein-san?" Eina was surprised to see Aiz, especially when she knew that Aiz was the culprit that caused Isao's wound. 

However, Aiz looked at the two with doubt and disbelief. 

"What are you doing here, Wallenstein-san?" Eina asked with a doubt. 

Aiz looked at Eina and then asked, "Why did you two kiss?" 

"Oh, I am her girlfriend," Eina said with a blush, then asked, "But why are you here again?" 

Aiz frowned but said, "I am going to take care of him until he is healed." 

"Oh?" Eina was surprised and then looked at Isao for confirmation. 

"Yes, she told me that she wanted to help me." Isao didn't intend to hide his relationship with Eina. Or rather, he wished for Aiz to see their relationship so she wouldn't do something obscene to his body once again. 

"Thank you for taking care of Isao-kun when I am not by his side, Wallenstein-san," Eina said softly and thanked Aiz. Yes, she knew that Aiz was the cause of Isao's injury, but she also knew that there was nothing she could do, especially when she was just a guild staff, and this matter was solved, so in the end, she just followed Isao and decided to forgive Loki Familia even if she didn't want to.

"...it's fine." Aiz frowned, but with her usual blank expression, it was hard to see the change in her emotion. She wasn't sure about these feelings, but instead of being hurt after knowing they were in a relationship, she was annoyed at Eina since this acquaintance of Riveria thought that Isao was as good as hers. 

"By the way, how is the guild reacting to my proposal?" Isao decided to ignore Aiz and asked about the proposal that he sent to the guild through Eina. 

"Yes, they accept, and you can start right away if you wish to," Eina said with a bright smile. 

"That's great." 

As the two talked about his business, Aiz didn't say anything and just sat close to Isao, never interrupting them and only listening to their conversation silently. 

"Oh, the guild head asked me whether it was possible to put Monsterphilia in your newspaper?" 

"Well, I plan to put it in my newspaper since it is one of the most famous events in the Orario. By the way, is the guild interested in making a newspaper? If they want, I can help them to make it, and I will give them a discount now." 

"They seem not to have such an interest currently, but I will tell you if they wish to." 

Hearing Eina's answer, Isao shook his head inwardly, thinking that they hadn't found the real purpose of the newspaper, but it didn't matter since once they knew how important it was, it was too late. 

Still, while Eina wanted to stay for a longer time, she also had to work on the guild. 

"I will go here as soon as I finish my work." 

"Take your time." 

Eina then kissed Isao's lips softly and excused herself. "Wallenstein-san, please take care of Isao-kun." 

"...um." 

Eina nodded softly, but when she left, Aiz came directly closer to Isao and kissed his lips. 

"..." 

Isao blinked his eyes and was dumbfounded. Still, when he thought that Aiz was about to be rough with him, unexpectedly, she just pressed her lips against his, then took out his penis as usual, squeezed it, and stroked it with enough force to give him the best comfort. 

It might only be a day, but Aiz knew what he loved the most and which part of his gave the most reaction.

"A-Aiz!" 

When their lips parted, Isao looked at Aiz in a shocked expression. 

"You don't have to worry. Just enjoy, okay?" Aiz said softly and gently. 

"This isn't good. I have a girlfriend." 

Even if Isao had accepted her advance last night, this time, it was different! 

Isao wished to make it right! 

Still, he didn't push her away as he was afraid that Aiz might snap his penis. 

"It doesn't matter." Aiz moved closer to him, sniffing his scent, and rubbed her face against his neck while stroking his erection, never letting him go. "I will comfort you~!" As she kissed his lips, she made up her mind. 

'You can only be mine.' 

"Aiz..." 

Yet, Aiz didn't say those words and kept stroking his erection until Isao could only focus on the pleasure from her soft and warm hand. She didn't care even if he had a girlfriend, or rather, it didn't matter since no matter what, he was going to be hers! 

Only Isao screamed inwardly, thinking that this woman was a beast!
