When the scene outside the window appeared in Sayu's eyes, she took a breath and her eyes became blurred for a moment.

After a few beats, he slowly opened the door and got out of the car.

Kato Yusuke also followed.

It was already nine o'clock in the evening.

Under the bright yellow street lights, several huge buildings are sitting in the darkness not far away, like monsters hiding in the night, waiting to be eaten.

——"Asahikawa Sixth High School"

This string of words is clearly written on the door number on the pillar at the door.

Sayu just stared at the teaching building in the distance quietly, with a particularly obscure expression on his face.

"Okay, then...I'll go there."

"Eh?"

Yisa's eyes widened immediately and he asked hurriedly: "Do you want to go in?"

The girl smiled slightly and replied calmly: "Well, I know where to go in."

Ogiwara Kazusa couldn't help but feel a little silent, with confusion on his face. He hesitated for a while before sighing and saying: "I understand, don't do dangerous things."

Sayu nodded imperceptibly, came to someone's side, pinched his sleeve, "...I'm afraid of being alone, and I want Yusuke to come too."

"I would have gone even if you didn't tell me." After hearing this, Yusuke rubbed her head and said, then turned his eyes to Ogiwara Kazusa.

"Then let's go there."

"Be careful on the road." Yi Sa responded succinctly: "It's up to you, Sayu."

"I know." Yusuke responded and followed the girl walking along the wall outside the school.

Because there were surveillance cameras at the school gate, the two of them could not enter or leave through the main entrance. Instead, they walked towards a shortcut under Sayu's leadership.

We walked around the perimeter and came all the way to the back of the teaching building.

"Okay, here we are."

Sayu breathed a sigh of relief, "Great, this place hasn't been repaired yet."

Following her gaze, what caught her eye was the barbed wire fence that surrounded the teaching building. There was an obvious big hole in the corner, showing signs of vandalism.

"It turns out that there are also people who skip school when they enter high school?" Kato Yusuke sighed casually, and the girl said, "Yeah, it's true."

"The hole was not that big originally, but it was later made bigger and bigger by people who wanted to skip class midway, so you can get through it by squatting down a little."

After explaining, Sayu squatted down and got through the hole first, then waved to him: "Yusuke, come quickly too."

Kato Yusuke followed closely and slipped through underneath and entered the school.

I stood up and looked at the teaching building. Apart from the layout being slightly different from the private Toyosaki building, there was nothing special about it.

However, when I thought that schools across the country should be pretty much the same, I immediately put this thought to the back of my mind.

"We trespassed together."

"This is the second time."

"Eh?"

Looking at the girl who tilted her head slightly, Yusuke smiled and casually mentioned: "And that time in Shinjuku."

"ah……"

Sayu, who recalled the Fangcun brother and sister incident, opened her mouth as if in a daze, and then puffed up her cheeks and said: "Really, I was really - worried at the time..."

After saying that, he shook his head sadly and murmured: "...Although it's only been half a year, I still feel that we have experienced a lot of things together."

Affected by these words, Kato Yusuke's eyes were lost in thought for a moment, and then he followed Sayu's example and shook his head, reached out to hold the girl's hand, and said yes.

Holding hands, the two people stepped forward again and strolled through the deserted campus.

On a clear night, the stars in the sky are shining, like countless silver beads, densely embedded in the deep black night, casting a dreamlike light, slightly illuminating the school building.

The beautiful scene makes anyone looking up casually feel lingering.

"The stars here are much brighter than in Tokyo."

When he said this, Sayu immediately looked back and said in an excited tone: "Yes, the stars here are really beautiful to the point of being annoying."

"It's not a good thing for people who invade illegally." Yusuke looked away and joked with a smile.

"Hehe, but you are still a little excited, right? This kind of thing."

"Where did you come from, a rebellious kid?"

"I'm not a brat! After all, Yusuke should definitely call me sister, right?"

"Don't label yourself as a senior, besides..." Kato Yusuke suddenly smiled a little meaningfully: "I like it very much when you call me daddy."

Sayu's feet suddenly stopped. As the scene from a few hours ago appeared in her mind, her cheeks instantly turned red. Then she unnaturally lowered her gaze, cursed a bad guy, and quietly quickened her pace.

The two of them walked to the back door of the teaching building together.

He raised his hand and grasped the handle of the metal door that was obviously not for students to enter and exit, and then turned it to one side.

boom.

With a sharp metal sound, the door was opened.

Sayu smiled happily again: "The door lock here has been broken for a long time, and it has been contracted by students who have been skipping classes."

"Don't schools even repair it?"

"Because even though there are people going out here during the day, no one comes in at all at night."

Kato Yusuke couldn't help but feel a little speechless, and at the same time he lowered the security evaluation of this place again.

But when I think about it, even if I go to high school, I am still in a stable countryside, so the school's slow response in maintaining these facilities makes sense.

Enter the building through the metal door.

The dim corridor had no other lighting except emergency lights, and the environment was so quiet that it was a bit eerie.

The light green light flickers faintly, illuminating the surrounding walls with a pale green color and forming strange shadows on them, giving people a strange psychological suggestion that can easily be associated with it.

The strong contrast is really unimaginable, how lively and vibrant it is here during the day.

In such an environment, it is not difficult to understand why there are so many "weird stories" and "seven mysteries" on the stage of school.

While thinking about this, I felt a sense of warmth on my arms.

Turning around, he saw Sayu, who had been unresponsive just now, hugging his right arm tightly.

"This is my first time coming to night school, so I'm a little scared."

Feeling the anxiety in her words, Kato Yusuke asked jokingly: "Then do you want me to hold you? My princess."

"...That's good."

The other party shook his head, pointed forward, and whispered softly: "Let's go there and then go upstairs."

The smile on his face faded, Yusuke hesitated and asked again: "Where do you want to go?"

A brief silence.

"Rooftop." Sayu whispered, her voice trembling slightly.

Kato Yusuke immediately calmed down and stayed there for a while before he slowly uttered the word "good".

Then he moved forward step by step, matching the girl's rhythm.

Go up the steps from the corridor at the end and start going up the stairs.

During this period, Sayu held his arm with increasing strength, but said nothing.

After feeling this, Yusuke grabbed her hand with his left hand, then took his arm out of the girl's arms and put his right arm around her shoulders.

The white moonlight shone in from the window on the landing, shaking their shadows and giving them a cold gaze.

Tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap, tap.

The footsteps of the two people echoed in the quiet teaching building, bringing with them a faint echo.

They didn't say a word until they reached the top of the building.

Just in silence, he came to the door leading to the rooftop.

"arrive."

"good……"

Sayu responded quietly and let go of his hand, walking to the door.

Click, click.

Of course, the door here is locked.

Before Yusuke Kato can breathe a sigh of relief...

Click.

The square window located a little distance next to the door was opened.

"really……"

The girl murmured to herself: "The door to the rooftop has been locked since then, but the lock on the window here is broken. Let's get out from here..."

This school... Kato Yusuke sighed secretly in his heart and turned his gaze to the window.

Valley

Just like the dog holes in the iron fence outside the teaching building, although the windows here are not big, they are still big enough for a person to pass through as long as they are not too fat.
