Should I change the past?

On that day, the world was in a panic, as if a dangerous being was about to wreck everything. Yet, no matter how they searched, the source of this danger remained elusive, adding to the sense of hopelessness. 

So, after a few days, while some people had decided to forget about it, some were still anxious, wondering what was happening. 

Yet, it was impossible to find anything since Isao's "Area of Invisibility" had reached a level where even a god couldn't discover him. 

Still, amidst that danger, happy news was heard for the entire Yotsuba Family. 

Why so? 

Well, it was because the head of the Yotsuba Family, Yotsuba Maya, decided to marry. 

Yup, the famous head of the most dangerous and elusive magician family decided to marry someone and became the wife of that person. 

Naturally, this decision left everyone in a state of shock. 

Maya's past was an open secret; all of them knew about it, but no one was thoughtless enough to discuss it or talk about it, considering how dangerous the Yotsuba Family was, so the thought of her marrying someone never crossed their minds, but then if she decided to marry, then it didn't matter since to see someone to marry at her age. 

Moreover, Maya was still in her prime, so why shouldn't she marry someone? 

At the same time, love had always been blind, so even if Maya's situation was like that, if her partner was okay with that, then why should they be troubled by it?

"I see! Maya is going to marry!" 

Kudo Restu, the head of the Kudo Family, was surprised, then smiled. "That's good. We should prepare a gift for her." Even though their family might be in the competition as the balance of the Ten Master Clans tilt and most of the power was taken by the Yotsuba Family, Maya was his previous student, and he was also a friend of Maya's father. More importantly, he also knew Maya's past, so even if they might not have a good relationship, he still had to congratulate Maya for this happy event. 

The same could be said for other families on the Ten Master Clans since all of them also congratulated Maya, and they were ready to prepare their gifts and, of course, waiting for the wedding invitation. 

However, as many were happy, some couldn't be happy and felt conflicted, especially Kouchi Saegusa, the current head of the Saegusa Family, one of the Ten Master Clans. 

While many knew him for being crafty and also tried any means to make the Yotsuba Family lose its influence due to its strength, and due to that act, he was also known as the "Sly Fox." 

At the same time, due to the seeming hatred that appeared between the two, no one would think that he was Maya's previous fiance. 

In the past, they were in love, and they were ready to marry each other, but their study trip in Taiwan changed everything. 

Maya was kidnapped, experimented, and raped for three days before she was saved, but after all of that, she lost her ability to get pregnant and also lost her life as her experiences, memories, and everything were modified by Maya's magic. 

On the other hand, Kouichi lost his right eye after he lost his fiancee. Even though he might have married twice, he couldn't help but think about the past when he heard Maya decide to marry. 

Part of him wished to stop it, but he knew that he could do nothing, especially when no one ever thought for her to marry, and if he decided to stop it, the others would think that he was just... a sore loser who couldn't accept his former fiancee went to marry someone. 

Yet, regardless of what would happen, he needed to know who Maya would marry with. 

Or rather, Kouichi wasn't the only person who wanted to investigate this matter, and many wanted to know who Maya would marry. 

What kind of a man had conquered the heart of the most fearsome magician in this country? 

Still, while Kouchi's feelings were conflicted, Tatsuya and Miyuki were even more so. While they were shocked that their mother had decided to divorce even though Miya was pregnant, they were even more dumbfounded when their teacher, Iinuma Isao, decided to marry their aunt, Maya Yotsuba! 

Whether Tatsuya or Miyuki, they knew their aunt well, and they knew the horror of the woman they called an aunt. It might not even be wrong to say that Maya was a lunatic, yet somehow...

"...I don't feel surprised somehow," Miyuki murmured. 

"That's true." Tatsuya nodded. 

After the Okinawa trip, the relationship between siblings was no longer cold, or rather, there was a tendency for Miyuki to do something forbidden due to her overflowing love for her older brother.

Yet, Tatsuya felt strange since he thought that Isao would marry his mother. Frankly, he hoped for Isao to be his stepfather since the only one that he could rely on in this world was Isao. 

Still, no matter what, they had become a family, and having him as an uncle... definitely wasn't a bad idea. 

However, if there was something that they were worried about, they wondered what would happen to the marriage of Maya and Isao as they knew that Maya couldn't get pregnant, but—

"I-I am pregnant..." 

Maya looked at the pregnancy test that she had taken so many times as she looked at Isao with reddened eyes. 

"Thank you, Maya." 

Hearing those words, Maya cried and hugged him directly with excitement, happiness, and many others. The simple happiness of being a mother that she couldn't dream of in the past was achieved. She could become a mother, and at the same time, while she lost her past, she still had her future, and as long as she was with him... 

"Don't cry, okay?" 

Patting her back softly, Isao looked at Miya and Saeki, who also cried. Saeki aside, as she was probably affected by their interaction, he knew how happy Miya was for Maya to be able to get pregnant. 

Miya was the one who killed Maya in the past, and due to that decision, she had been living with the guilt that she wished to kill herself. 

Yet, watching Maya able to become happy, Miya could truly be freed from her guilt. 

Still, what was left was to marry Maya. 

Maya had children and was also about to become his wife. 

At the same time, this also made Isao wonder whether he could give a surprise to the two and if there was something that could make them happy. 

'Their father...' 

If there was something that could make them happy, it was to make them meet their father, who passed away in another country after he killed everyone and destroyed a country that was responsible for his daughter's tragedy. 

While many people in this world were shitty, Isao had to say that he felt impressed with Yotsuba Genzou, the father of Miya and Maya, who was ready to give his life to avenge his daughter. 

Isao wanted to resurrect Genzou, but he wondered whether it was possible, especially when his corpse had probably disappeared after so long. 

Still, the best way for him to give them happiness was probably to go to the past by using his time manipulation ability, erasing the tragedy that happened to the Yotsuba Family. 

Yet, as he thought so, he couldn't be helpless by the ability of the time manipulation he gained from the world of Rakudai. 

'If I don't have this ability...' 

If he didn't have this ability, then he wouldn't think to go to the past to change everything, but he had this ability, so he couldn't help but think about the possibility of using this ability. 

Yet, he also knew that if he used this ability, as fate changed, naturally, he would lose the three women with whom he had made a connection within this world. 

If Maya wasn't kidnapped, then she would marry her fiance. 

If Miya hadn't been guilty, then she could have spent her days better. 

As for Saeki? 

Fortunately, Saeki was all fine, which made him sigh in relief. 

"What's wrong?" 

Still, Miya noticed his worry due to her magic, so when the night came, she couldn't help but ask. 

Isao looked at Miya, Maya, and Saeki, who looked at him. While hesitant, he thought for a while and said, "Do you know I have time manipulation ability?" 

"...." 3x

While they were dumbfounded by this ability, they quickly realized what he would do with this ability. 

"...do you want to go to the past to change everything?" 

"Yeah." Isao nodded. "What do you think?" While he had to say that he would be hurt if he lost Miya and Maya, if he could erase their tragedy, then he felt it would be worth it. 

"No!" 2x

Maya and Miya answered at the same time, and their voices were high, showing how emotional they were. 

"Don't go!" 

"If you go, then we won't meet, right?!" 

Instead of the past, they looked forward to the future with more, and even if the past could be changed, could they even be happy? 

Their father might be there, but if Isao wasn't there, could they be truly happy? 

Watching their expression, Isao also felt relief and nodded. "I won't go." 

"Re-Really?" 

"Yeah, I haven't married you, after all." 

This guy might not be able to control his lower body, but even so, Isao wasn't someone who would break his promise. 

Yet, at the same time, Isao also sighed in relief after he talked to them since it felt like... he had a bone stuck in his throat when he knew he could go to the past to change their past. 

Nevertheless, as he thought of marriage with Maya, he couldn't help but think about Syr's confession in the world of "Danmachi." He knew Syr's real identity, so he had a headache, thinking about what to do with her confession. 

If he refused, he knew that the world would be in chaos, but if he agreed...

'Well, I should agree, right?' 

Anyway, it was just a date, so at that moment, he didn't hesitate and decided to answer Syr's confession. 

As for his marriage with Maya? 

Well, it was all fine to wait for a while, right? 

Especially when Isao knew that he had to focus on defeating Dionysus first. 

At this moment, he decided to go to another new world, wondering what kind of gain he could gain. 

Time stopped, and a bright light appeared. 

Isao entered the light without hesitation, and he was teleported to another world. 

"Hey, guys! Look at him! We're lucky!" 

"That face... Uwooo! I can tell that he will fetch a lot! Those noble ladies will be crazy of him!" 

"Wait! Wait! Can we taste him first?" 

"....." 

As he heard those words, Isao realized that he was surrounded by many bandits. 

With menacing and dirty appearances and weapons in their hands, all of them had a smug and cocky smile on their face, but even more hatefully, some of them even lusted toward him. 

Well... his luck was as great as ever, he thought.
