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

Since Takagi Yayako was waiting for someone, Yoshiyuki and the other two said goodbye and continued towards the main teaching building.

The chairman's office is on the top floor.

"What a huge school!" Yixing exclaimed, looking around. He pointed to a nearby building with an artistic, crystal-like dome: "That's the gymnasium, isn't it?"

"Yeah." Yusuke nodded. "Yoshiyuki, you're so good at kendo, why don't you consider joining the club? You can use the school's dojo anytime, it'll be much more convenient for you to practice."

"It's definitely worth considering." Yoshiyuki became interested and turned to look at the young lady: "What about you, young lady? You've come all this way to Tokyo to study, you can't possibly join the 'Going Home Club,' can you?"

"I'm planning to join a game club or anime club!" Erina exclaimed eagerly. "Of course, I'm also considering starting a dumpling club. Then everyone will know how wonderful dumplings are!"

"Who would join such a boring club?" Yusuke chuckled. "By the way, Erina, have you considered joining the student council? The new president seems quite interested in you, you know?"

"What?! You're interested in me?!" Erina asked warily. "What kind of interest?! Did you catch my liking for teasing me too?!"

"No, no, I just want to be good friends with you," Yusuke explained. "And I also want to study what's so special about the Yomi Shrine Maiden's body."

"How do I study it?" Erina asked, looking completely bewildered.

"It means slicing you up," Yixing explained promptly.

"What?!" The young lady was immediately shocked. "No, we have to find a way to get rid of this woman!"

"No, no, it's not that exaggerated." Yusuke laughed and said, "She probably just wants to pluck some hair and bleed a little. She also studies underworld magic, and these are valuable casting materials!"

"No! It hurts!" Erina immediately cried out in refusal, "I won't give it to her!"

"What if I gave you a dumpling?" Yusuke asked.

"Do you think I'm the kind of woman who would succumb to the temptation of a mere dumpling?!" Erina paused, then muttered softly, "But since it's a limited edition, I might consider it..."

"Young Miss, your principles are truly fragile!"

Yi Xing complained like this, then turned his gaze to the buildings further away.

It was incredibly tall, even taller than the combined height of the laboratory building and the student activity building.

The architectural style is somewhat like a Gothic church bell tower, and also somewhat like a castle tower, creating a stunning and perfectly harmonious fusion.

"What is that?" Yixing asked, pointing at it.

"A grand library with a giant spiral staircase, and a clock tower with an indoor garden on the top floor for observation," Yusuke replied. "It also serves as the core of the barrier, a sanctuary, and a residence."

"What do you mean?" Yixing was utterly confused.

"Let me explain the core of the barrier first." Yusuke put on a serious expression: "Because there are many spiritual beings in this school, it is easy to attract strange phenomena and demon attacks. In order to protect the students, with the help of Sakura-gami Hatsuyuki, the chairman of the board set up a magic circle core in the clock tower library in the center of this campus, using Hatsuyuki Shrine and several other places as array eyes, creating an exorcising barrier."

"I see." Yixing nodded. "Can it completely prevent evil spirits from entering?"

"The range is too large, that's impossible," Erina chimed in. "It can only frighten many evil spirits, preventing them from entering. Even if they do enter, their power will be weakened. It's impossible to completely prevent them. In reality, even the strongest barrier cannot completely stop the invasion of evil spirits. There are all kinds of powerful demons and evil spirits."

"Hmm, as expected of my sister, her perception is really strong." Yusuke's tone was somewhat proud, and then he continued to introduce her.

"Next, I'll explain what the shelter means. That clock tower library is extremely sturdy, with many mechanisms and fortifications. Because it's located at the center of the barrier, it's most effective at dispelling and weakening evil spirits, so you can basically feel safe escaping inside if you encounter danger."

"I understand that." Yoshiyuki was intrigued. "But what do you mean by 'accommodation'? There aren't any boarders here, are there?"

"No, not really. But there are two people who live at the school. Their rooms are in the clock tower," Yusuke said with a chuckle. "One of them is Chairwoman Shimizu Tamako. The other one, well, she's a strange girl—ah!"

Hearing his brother say this, Yixing looked in the direction his gaze was focused.

Sure enough, a black-haired girl in a kimono was standing not far away.

She has a loli-like appearance and black herringbone hair.

He had a katana at his waist.

One can sense a strong demonic power emanating from the girl.

Especially that knife, which exuded a menacing aura.

However, due to the girl's restraint, the aura did not harm those around her. This shows that she had no intention of harming anyone.

"Here she comes, here she comes," Yusuke whispered to the two of them. "Nobody knows her background or name. Because the sword she carries is quite sinister, and she always wears a kimono and has an ancient princess hairstyle, everyone calls her the Demon Sword Princess."

"I see... But the chairman should know her identity, right? Otherwise, why would he keep her at the school all this time?" Yoshiyuki asked.

"Perhaps, but when I asked her, she just said she didn't know." Yusuke said, then looked at Yaodao-hime and continued, "Usually, she spends most of her time in the library, reading, daydreaming in the indoor garden, or looking at the scenery from the clock tower... She rarely comes outside."

"Seriously, that's strange. The Demon Blade Princess is actually staring at someone." Yusuke noticed that she was staring at Yoshiyuki and Erina, and was a little puzzled. "Normally she completely ignores people. She never speaks and has no expression. She doesn't seem to have any emotional fluctuations."

"They were probably attracted by the aura of the underworld emanating from the young lady. Nothing special." Yixing didn't think much of it and suggested, "Let's go, into the teaching building."

The three continued toward the teaching building.

But as he walked, Yixing sensed that something was wrong.

Looking back, sure enough, Yaodao-hime was following behind.

Her expression looked somewhat hesitant.

When she noticed Yixing looking back at her, she stopped in her tracks and lowered her head.

His eyes were filled with sorrow and longing.

"Hey, you call this expressionless and emotionless?" Yoshiyuki grabbed Yusuke, quietly pointed in the direction of the Demon Blade Princess, and whispered, "So what's her situation right now?"

"This—I don't know either!" Yusuke was also a little confused for a moment: "Is she trying to say something?"

(PS: The Demon Blade Princess has nothing to do with Onmyoji; a separate chapter will clarify this later.)
