My daily life of exorcising demons and falling in love with a witch.

"Nice association! But terribly wrong." Shinsuke Shimamura caught the coin and flipped it rapidly between his fingers. "I'm not even thirty yet, Miss Yoda! She's sixteen. If she were my daughter, wouldn't I be a father before I've even grown my hair?"

"So this is your sister?" Yoshiyuki asked Investigator Shimamura, glancing at Akemi Shimamura, who was whispering to Takagi and seemed to have calmed down a bit.

"No, it's my sister."

"???"

Yoshiyuki and Erina were stunned.

The young lady looked at the girl with pigtails again, and then complained.

"Hey, Shimamura, are you kidding me! You're more than ten years older than her!"

"Hahaha, the situation is a bit special!" Shimamura laughed loudly, then lowered his voice and whispered to the two of them, "Actually, we are indeed siblings. Blood relatives."

"I really couldn't tell." Erina said with a look of disgust, "Shimamura-san looks so cute, how come your younger brother is so annoying?"

"What's the point of men pursuing cuteness? I'm not My Little Pony."

"Wait a minute, isn't the point why she's still in school at this age?!" Yixing said speechlessly, "She should have gone to high school more than ten years ago! Did she never go to school, so she's here to experience it?"

"That makes sense," Erina agreed. "Many immortals are like that. Some even miss school life every few years and go back to it."

"My sister's situation is a bit special. Although Mingmei was born in the same year as me, she is only sixteen years old both physically and mentally. She never went to high school."

When Shinshoujima Village got to this point, his expression became unusually serious, and his tone was tinged with guilt.

"When we were little, we were attacked by demons during the Twilight Hour. To protect me, Akemi used a sealing technique that she hadn't mastered yet. It bought us time, but because the spell was imperfect, she fell into a deep sleep. Not only did her physical growth stagnate, but her mind also remained in that twilight... She slept like that for more than ten years, and only woke up last year."

"...It took that long." Yoshiyuki was deeply shocked upon hearing this: "Mr. Shimamura, could it be related to this that you became a mystery investigator?"

"Pretty much. I just hope that through my efforts, we can reduce the number of tragedies like this."

Shimamura Yasuhiro caught the coin one last time and put it in his pocket.

"Actually, I'm quite satisfied with this result. After all, I originally thought she would never wake up again! Haha! I'm an investigator who never knows when I might suddenly die while dealing with demons. Taking care of her is my responsibility, and it wouldn't be good to leave her to my increasingly elderly parents."

He smiled again, adjusted his hat brim, and continued.

"Alright, we'll talk again sometime. I still have to investigate the case... Please try to get along better with Akemi, okay? I'll sing you a song as a thank you later!"

"You're already doing us a huge favor by not singing in front of us," Yixing said, immediately refusing, recalling that terrifying voice. "Listening to that song felt like being attacked by a demon!"

Investigator Shimamura quickly took Akemi away.

Before leaving, she waved goodbye to everyone, climbed onto the Gatling Bodhisattva, and asked it to follow her brother.

So the massive bronze statue began to follow behind the village of Shenqiang Island, step by step, toward the door.

For a moment, the ground trembled as if a magnitude 3 earthquake had occurred.

"Takagi-san, the person you're waiting for has already left. What are you going to do now?" Yoshiyuki asked Takagi Yayoko, "Want to come with us?"

"Ah, no. I'm waiting for someone else. We're going the same way, so we'll take the train back together." Takagi scratched his head and chuckled, "You two know this guy well, right? He's a descendant of Hermann, you know?"

The name she mentioned is completely unfamiliar to the vast majority of Japanese people.

But anyone who knows the hidden history of the Battle of Fengmen will be very familiar with it.

The first Yomi Shrine Maiden and Maekawa traveled all over Japan to perform rituals and prepare for sacrifices in order to seal the Gate of Yomi.

Along the way, they recruited many warriors to join their ranks.

One of them was a Westerner: Herman Amis.

According to the records of the Yoda family, the Templar Knight placed all his hopes on a rumor among merchants that the Great Tang Empire in the East had a magic pill that could cure his sister's witch disease.

Therefore, Hermann renounced his title and religious status, sold his property, and took his gold and silver across the ocean from Europe to the Tang Dynasty, hoping to find the elixir of immortality in the Shu Mountains.

However, the Shushan Sect was in turmoil at the time, and the demon realm opened a portal from here to invade the mortal world. Shushan then set up a barrier to seal off the mountain to prevent demons from escaping, so Herman was naturally unable to enter.

In his despair, a Shushan swordsman who was also unable to return to his sect due to the sect's closure was moved by Herman's love for his sister and told him that an alchemist who had violated the sect's rules and was expelled from the Shushan sect had escaped to Japan, and perhaps he could help refine the elixir.

So Herman accompanied him across the East Sea and arrived in Japan, a land ravaged by demons. During their search for the alchemist, they met the Witch of the Underworld and others, and joined forces on several occasions.

In the end, Herman successfully obtained the elixir after overcoming numerous difficulties, and the two also participated in the final battle to seal the gate. They survived the direct confrontation with Hades Izanami and returned to their respective homelands.

This swordsman from Mount Shu later made great contributions in quelling the internal strife within Mount Shu, becoming the sect leader. A hundred years later, he ascended to become a sword immortal.

But Hermann's fate was incredibly tragic.

He successfully returned to his hometown, saved his sister from the brink of death, and married and had children.

However, not long after, he was regarded as a heretic who betrayed the gods because he used the immortal techniques he learned from the Shu Mountain Sect and the Japanese Yin-Yang arts when fighting against demons and protecting the people. He was tortured but still refused to confess and died on the stake.

His sister was also tied to the stake and executed, but was resurrected by the witch's power. Afterwards, with the help of a merchant who sympathized with them, they found his wife and children, whom he had hidden, and escaped to Japan to seek help from the Yoda family.

The Yoda family was deeply saddened upon learning the news and helped them settle down. The Amis family has continued for a thousand years, to this day.

Herman's sister also gained immortality through the blood of a witch. Although she had long since stepped down from her position as head of the family, she remained the behind-the-scenes controller.

Because they had lived and raised their families in Japan for a long time, the descendants of Amis looked almost indistinguishable from Japanese people, and their names had all been changed to Japanese. The Amis family became the Jinbo family.

Due to their hostility towards the Holy Church of Radiance, the Shenbao family no longer uses the magic of this system, but still inherits the traditions of their ancestor Herman, while cultivating the Shu Mountain Immortal Arts and Yin-Yang Arts. To this day, they still frequently exchange feelings and techniques with the Shu Mountain Sect, and escort exchange students to study and live there.

The boy Takagi mentioned is Kikue Jinbo, who will also be entering her first year of high school.

He attends the grand festival held by the Yoda family every year to strengthen the seal of the Gate of the Underworld, and he is very familiar with Yoshiyuki.

Because he was also very interested in photography, he and Takagi always had a great time chatting whenever they met.

Hearing that they were now living in apartments on opposite floors, Erina immediately became very excited: "Looks like you won't be shy for long, Takagi!"

"Huh? What?!" Takagi Yoyako was taken aback. "What are you talking about, Yoda-chan?!"
