She was the heroine of this theatrical version, Kasuga Ren, the daughter of Kasuga Izuminokami Yasutsuna, the lord of Kasuga Castle.
Unsurprisingly, the samurai beside her, who had a Chonmage hairstyle, was Ijiri Matabei Yoshitoshi, the General of the Kasuga Army, known as the blue sky samurai.
"That's right, Mom and Dad, let's be guests at Kasuga Castle."
Nohara Shinnosuke said to Nohara Hiroshi and Nohara Misae.
Even if he hadn't said anything, Nohara Hiroshi, whose mind had relaxed after recovering his son, had already been captivated by the ancient beauty, Kasuga Ren, whom he had never seen before.
"Is that so? We are truly sorry for the trouble."
"Oh, right, my name is Nohara Hiroshi. It's a pleasure to meet you..." Nohara Hiroshi immediately changed his expression, shedding his previous tension.
Instead, he leaned forward with a somewhat bashful look and began introducing himself.
It must be said, they truly are a family.
The two people who had been so nervous and anxious moments before instantly reverted to their usual selves after finding Nohara Shinnosuke.
Kobayashi Itsuki clearly saw Nohara Misae's complete change of expression in the rearview mirror, and her instantly darkening face made the corners of his mouth twitch slightly.
Sure enough.
The somewhat carried-away Nohara Hiroshi was ultimately met with Nohara Misae's gritted "Husband!"
It was fortunate that there were so many outsiders around, or else Nohara Hiroshi's head would likely have gained a few more bumps.
After reaching a decision, the group decided to first go to Kasuga Castle and then slowly figure out how to return.
At Nohara Hiroshi's insistent invitation, Kasuga Ren got into the car and squeezed into the back seat with Kobayashi Itsuki and the others.
Taking advantage of this opportunity, Kobayashi Itsuki and the group introduced themselves.
[Ding. You have met Kasuga Ren. Current relationship status: White.]
[Congratulations, Host, you have received 1 White Treasure Chest.]
"A-Ren, this is Teacher Kobayashi. He's the Martial Artist I told you about! He's super amazing. He can take down dozens of people by himself and isn't even afraid of guns!"
Upon hearing this, Kobayashi Itsuki was speechless.
His so-called glorious achievements had become extremely exaggerated after Shin-chan's embellishments.
What did he mean, taking down dozens of people alone and not even being afraid of guns?
Even Kobayashi Itsuki felt a little embarrassed hearing it.
He felt even more awkward when facing the curious gazes of Ohara Nanako beside him and the Nohara Couple in the front.
"So you are Kobayashi-san. Shin-chan talks about you often; he admires you greatly." Kasuga Ren smiled, looking at Kobayashi Itsuki, unaware of the context.
"Princess Kasuga, you are too kind," Kobayashi Itsuki nodded and replied courteously.
After exchanging brief greetings, silence fell over the car.
The car drove through farmlands and eventually onto a bumpy dirt road.
After driving shakily for about ten minutes, they finally arrived at Kasuga Castle.
"Is this Kasuga Castle?"
"It feels very magnificent."
The car arrived at the gates of Kasuga Castle. Ohara Nanako looked out the window at the ancient castle before her, exclaiming in admiration.
"It has a more profound sense of history than modern cities."
Kobayashi Itsuki nodded, smiling.
Led by Ijiri Matabei Yoshitoshi, the car drove into the city.
Faced with the technology of the future world, the people of Kasuga Castle were all astonished, standing aside and gazing at the walking iron monster and Kobayashi Itsuki and the others sitting inside.
If it hadn't been for Ijiri Matabei Yoshitoshi leading the way, it might have even provoked an attack from the guards.
When the vehicle finally reached the inner city, Ijiri Matabei Yoshitoshi, who was leading on horseback, stopped and said, "You can park your vehicle at my house for now; the inner city is not accessible by car."
After parking the car, the group followed Ijiri Matabei Yoshitoshi towards the inner city. This was where the lord of Kasuga Castle, Kasuga Izuminokami Yasutsuna, resided.
Led by the princess and others, the group successfully met Kasuga Izuminokami Yasutsuna and received a grand reception.
Facing Kasuga Izuminokami Yasutsuna's inquiries about the future, Kobayashi Itsuki didn't interject.
Compared to that, he was more interested in the rustic architectural style around them.
They just weren't as magnificent... Thinking of magnificence, a thought suddenly flashed through Kobayashi Itsuki's mind.
If he remembered correctly, in the original story, when Shin-chan's family returned, Kasuga Ren and the others seemed to have prepared a generous gift, like gold bars, to express their gratitude.
It was just that the Nohara Family didn't accept it.
But thinking about it differently, did that mean he could acquire a large amount of wealth in this Warring States Period?
He still had a huge debt unresolved in modern society.
If he could get a lot of hard currency like gold here and sell it after returning to modern times, he could gain a large amount of wealth, saving him a lot of time.
'It doesn't seem impossible, but getting it won't be easy.'
The history of this country, Japan, isn't that long, let alone cultural relics.
There are scandals of fakes every year, and few authentic items.
If he buried something in the ground before leaving, it probably wouldn't sell.
Once it was discovered to be real, he would probably go straight to jail.
It would be better to get some gold or something.
'It seems I can only find a way to get it from others, for example, from the Okurai clan…'
Just as he was lost in thought, Ohara Nanako suddenly nudged Kobayashi Itsuki with her elbow and whispered, "Teacher Kobayashi, what are you spacing out about?"
"Nothing, I just think it's quite fantastical, isn't it? Traveling back four hundred years to experience everything that once happened."
"It's quite novel, but…"
Ohara Nanako said, letting out a soft sigh.
"I don't know when we can go back. My father is probably starting to worry about me."
Thinking of how worried Ohara Shijuro would be when she came home late, Ohara Nanako felt a bit anxious.
Before, when she thought of Nohara Shinnosuke's disappearance, she was so worried that she wanted to help. Now, she belatedly remembered that there were also people worrying about her.
"Don't worry, I don't think we'll be here for too long."
"After all, this is the Warring States Period. If we were really to stay here for a long time, there would likely be significant changes or differences in history."
"Our existence will change history, like the butterfly effect."
"Since history hasn't changed much before our arrival, it proves that we won't be staying here for too long. Maybe we can go back tomorrow after a night's rest."
Hearing Kobayashi Itsuki's words, Ohara Nanako's face showed a hint of relief.
