Be careful, okay?

A good person has always been tested. 

Isao knew that, and he was also ready for any trials or tribulations that came in his direction. 

Walking with Yuriko out of Souchiro's office, if it had before, Isao might have lost his calm, but he was no longer that young man who showed his pathetic self when he stood by the woman who happened to be his type. 

Whether it was Kie or Tamayo, they had trained him to become a better man, so even if Yuriko was by his side, he was pretty calm. "Are you really going to follow me, Takagi—" 

"Just call me by my name, or you can also call me mom," Yuriko quickly said before Isao finished. 

"Then, Yuriko-san." 

He couldn't call Yuriko a "Mom" since he couldn't see her as his mom. 

"But to answer your question, yes. I wanted to follow up with you since I am going to entrust my daughter to you and see if you are qualified to do that or not," Yuriko said calmly with a piercing gaze. 

Her gaze was like that of a mother-in-law who wanted to test whether the young man before her was suitable as a partner for her daughter. 

Yet, facing such a deviant-like gaze, Isao was troubled since Yuriko looked so cute and instead appeared intimidating when she showed such a gaze. Still, as she had decided to do so, he also didn't mind for her to follow him so she could feel relief that Saya would be following him. 

Still—

"Has Saya-senpai made up her mind to follow me?" Isao asked curiously, wondering when they discussed Saya would follow him on this trip around the country. 

"Oh, she didn't tell you?" Yuriko was surprised, but then she let out a helpless sigh, feeling helpless at how useless her daughter was. Her daughter might be intelligent, but in terms of emotion, she was really horrible, especially with that excessive pride of hers; yet, as someone with a high IQ, it was normal, right? 

However, with Isao's qualification, was he going to be troubled by the problem of women? 

Still, with Isao's playfulness, there was still a chance for her daughter since Yuriko was sure that instead of a bitch that opened their legs for him, what he sought for a wife was a partner that could fight side by side, and there was no doubt her daughter was suitable for that role. 

"But to answer your question, she told me that she wanted to follow you." 

"I see." Isao nodded. "If that's the case, then let's bring her on this trip too." 

"...we aren't going there with just the two of us?" Yuriko asked unsurely. 

"Er... you want to go pick up an RV with just the two of us?" 

"Are we not?" 

"....." 

Isao's lips twitched, wondering what this mother of one wanted to do with him when they were alone together, but as a boy, he had to protect himself, so he said, "No, I will take some of the people with me since there is something that I want to do after I have picked up an RV." 

"Okay." 

While Yuriko wasn't sure what Isao planned to do, as the follower, she decided to entrust everything to him. "So, what should I do now?" 

"First, how about you change into easy-to-move clothes?" 

"..." 

Yuriko looked at her crimson dress for a while, then nodded. "You are right. I will change my clothes first." 

"Oh, please invite Saya-senpai too. I am going to be busy for a while since I am going to tell everyone that I am going to leave." 

"Sure." 

Who was "everyone" in his mouth? 

Yuriko wasn't so stupid as to ask this question, but she had to say that the boy's mouth was so slippery. 

Watching his back, her eyes were like a viper that locked into her prey, and she definitely wouldn't let him go.

Isao wasn't sure what Yuriko was thinking, but he had faced many dangerous situations, so while it was dangerous, even if he was targeted by a charming, mature woman, he was going to fight for it! 

"Ah, you are going to leave again?!" Rei was startled. 

On the other hand, Kiriko stared at Isao silently. Unlike her daughter, who was surprised when Isao planned to go out, she slightly resented this young man, who put her to sleep by her daughter's side after all of that! 

When Kiriko woke up for the first time and saw her daughter, who was looking at her, her heart stopped. Fortunately, her daughter didn't know anything, and her excuse was easily believed, yet she felt this young man was so bad~! 

"But where? What are you going to do?" 

Still, watching her daughter, who was cornered about her boyfriend, Kiriko was helpless and decided to keep quiet about what they did to her grave, and definitely, they wouldn't do something like that again! 

Probably...

Isao didn't know what Kiriko was thinking, so he only softly smiled at her, thinking that she was happy that he had put her on the same bed as her daughter. 

Kiriko's lips twitched, and they had an urge to beat this guy up! 

Letting out a helpless sigh, Kiriko wondered how she could let herself be pushed by him, yet she also understood why her daughter was crazy about him. 

Nevertheless, Isao explained what he planned to do, whether it was his plan to trip around this country and also to get an RV. 

"Y-You are going to get an RV?!" Kiriko was dumbfounded. 

Watching her mother's expression, Rei was glad she wasn't alone, who thought her boyfriend was crazy. 

"Yup." Isao nodded. "So take this. I am not going to be here, so use this to protect you." He took out two guns from his bag and gave them to Rei and Kiriko. 

"..." 2x

"Don't refuse me. You should hold these since I am not by your side, and anything can happen." 

Isao decided to leave the Takagi estate, and because of that, he wanted them to prepare, especially when Takashi was around. It wasn't that he was worried about what Takashi would do to them, as Takashi was the protagonist, and no matter what, a protagonist wouldn't do anything that was evil. 

However, Isao was sure that the world would cause Takashi trouble so that, as a protagonist, Takashi could grow. He wasn't sure what kind of trouble, but it wouldn't hurt for Rei and Kiriko to prepare themselves. 

As Rei listened to him carefully, Kiriko looked at the gun in her hand, which was something that the police usually used. Isao got those pistols from the police, who passed away on the street previously, and he directly gave them to the pair of a mother and a daughter. 

While Kiriko felt complexed by this naughty boy, she could tell that Isao treasured the two much. She was glad that Isao was her daughter's boyfriend, but she definitely wouldn't allow him to do something naughty to her body again! 

Definitely! 

Frankly, Isao wanted to bring the two, but as they were exhausted after waiting for him last night and helping him with various things in the morning, he didn't bring them. Still, after he gave protection to the two of them, he went to Saeko's room, telling her his plan to go out. 

"I will go out with you—" 

Saeko flinched when she was about to get up, feeling sores on her lower body, and Isao quickly held her, telling her to rest. "You are exhausted now. You don't have to force yourselves. Just stay here. I will go back in the evening." 

"Then, be careful." 

Saeko knew that she would be a burden if she followed him, so she didn't force herself. Still, as they had confirmed their relationship, she hoped that he would be safe and be alright from the danger. 

"I will." 

Kissing her forehead gently, Saeko blushed shyly, then hugged him tightly. 

Only Naomi and the other girls looked at the two helplessly. 

Still, before Isao left, he also gave them some protective items, such as scissors and a knife, which he had previously picked up. He also gave Saeko and Naomi a gun so they could protect themselves, and he explained how to use it. 

Holding the gun in her hand, Saeko looked at Naomi, who carefully listened to Isao's explanation. She shook her head, thinking that it was impossible since Naomi had a boyfriend, right? 

However, as he was finished with his explanation, he left and walked toward his next target, who was Shizuka and Kyoko. 

"Eh? Are you going out again?" Kyoko was dumbfounded. 

"Yes." Isao nodded. "But stay here. I will go back quickly." 

"Okay." Kyoko was obedient, but Shizuka was surprised. "Eh? Am I going to?" 

"Yeah." Isao looked at Shizuka and said, "Didn't you tell me that your friend has a collection of weapons? I need those weapons for everyone." While in the "Kimetsu no Yaiba" world, he had collected many weapons. They were weapons post World War One and were outdated compared to modern weapons in the 21st century. 

Still, as Shizuka hesitated, Isao said, "Let's get some cosmetics and dresses along the way after we get the RV." 

"Okay~!" Shizuka nodded obediently. 

While Isao rolled his eyes, he was glad that he had gotten Shizuka, but then Kyoko said, "Ah, can you pick some for me too?" 

"...okay." 

Still, with all of this, their team was completed. 

As Isao walked out to the gate with Shizuka, Saya was there along with her mother, Yuriko, who had changed into black pants, a white shirt, and a gun holster on her arms, which she concealed with her jacket. Still, what attracted him the most was her beautiful hair, which was tied in a ponytail, showing the whiteness of her nape. 

"Are you really going to pick up an RV?" While Saya was speechless, she was eager to follow him. 

"Yes." Isao nodded gently and asked, "Are you ready to follow me?" 

"Of course!" Saya was ready for this since she had been the one who was left behind, and this time, she got a chance to be with him, so she wouldn't let this chance up! 

However, Yuriko's concern was different from her daughter's. "Why did you bring Marikawa-sensei too?"

When Shizuka wanted to say something, Isao said, "She told me she wanted to get some cosmetics, beauty items, and dresses." 

"....." Yuriko and Saya. 

"Um, yes!" However, somehow, Shizuka nodded and agreed to his words. 

"Okay, let's start our trip so we can return quickly." 

"Okay!" 3x

The three agreed and followed his lead to go out, ready for their trip to get an RV, cosmetics, and some dresses! 

Only when there were four left was it seen by Takashi and Hirano. Watching the four leave without telling them, they felt like they were being left out somehow. However, when they thought about what they did, they knew that they couldn't be entrusted, especially Takashi, who had messed up and left Hirano and Takezo. 

"No, I can't continue to be like this! I have to be used by everyone!" 

"What are you going to do, Takashi?" Hirano asked curiously, seeming to forget that Takashi had previously left him behind. 

"Let's ask the boss of this place." 

As Takashi said, he looked at the room on the corner of the estate, the place where Saya's father stayed, thinking that he should ask the leader of this place what he should do to regain everyone's trust in him. 

---

By the way, you might have realized it, but I have added more chapters for the tier "Want Try Again" to 3 chapters and the tier "Learning" to 5 chapters.

Anyway, please enjoy~!

Lastly, I plan to add the advanced chapters to 50 chapters, so I am working hard for it.

Hopefully, I can realize that before the end of this month.

Thanks~!

As for whether Isao will return to the world of "Kimetsu no Yaiba," I will probably write it in the future, so don't worry~!
