Not much useful information was obtained in the Rat City, but Yuki Tomikawa's name was found on the signature list. Since Yuki Tomikawa had written her name on it, it meant that she had cleared a secret in the Rat City, but the memory had disappeared with the secret.

But school had already ended by this time, and Yuki Tomikawa had probably gone home, so they certainly didn't know where Yuki Tomikawa's home was.

[Go to the school and ask. Each student's home address is recorded in the student file.]

[No, you may not get any information if you ask the school at this time.]

【Let’s go check it out first. 】

Dazai Osamu was not too interested in the Rat City. Rather than investigating what was in the Rat City, he was more inclined to investigate whether the Rat City had any connection with a person called a rat. After all, the theme of the Rat City was secret, and the demon was an internationally renowned intelligence dealer.

It would be very troublesome if there was a real connection.

The wind was a bit cold tonight. Kamiya Izuru glanced at the sky and it should rain soon. He found a spare umbrella from the detective agency and walked into the school with the umbrella.

The school is not far from the detective agency, so even without a taxi, it is quick to reach the destination. As soon as Kamzuchiru stepped into the school, he heard thunder and raindrops fell heavily. If Kamzuchiru was a step late, he would be soaked. Because of the rain, no teachers stayed in the school today, and it was pitch black everywhere.

Kamuzuru Izuru walked forward holding an umbrella.

[Since you have calculated the time, why do you still need to bring an umbrella? ] Hinata Hajime asked in confusion.

【For your use. 】

【Give it to me?】

Kamiya Izuru didn't explain, he just walked into the school with his umbrella. In a warehouse not far from the teaching building, Kamiya Izuru stopped. Before Hinata Sou could ask, he heard a very faint cry for help.

The girl's sobs were mixed with fear, and she seemed to have even lost her voice, and her voice was weak.

Someone was locked up in the stadium warehouse.

Kamijou Izuru pointed to the location, then closed his eyes. When he opened them again, his eyes had turned light green. Hinata Hajime glanced at the umbrella in his hand, then looked at the location where he was still calling for help. He sighed helplessly, but quickly ran to the place where he was calling for help.

Kamijou Izuru doesn't know how to comfort anyone, nor does he force himself to comfort anyone, so it would be better to let Hinata Sou come at this time.

The closer they got to the warehouse, the louder the girl's voice became, and the more familiar the voice sounded to Hinata Hajime.

"Help, wuwu, help me, I won't dare to do it again."

"Please, let me out."

"It's so dark in here! So scary!"

【Yuki Tomikawa? ! 】

"Don't be afraid, I'll let you out now." Hinata Hajime quickly said, "Is it classmate Tomikawa?"

There was silence on the other side for a few seconds, and then a cry for help that was almost like a scream came out, "Mr. Hinata! It's you! Save me, please save me!"

"I'm right here, don't worry."

Hinata Hajime used all his strength to pry open the latch on the warehouse. With a click, the warehouse door was opened and disheveled Yuki Tomikawa immediately ran out. She was wearing her daytime school uniform, but it looked a little dirty. Her whole body was wet as if it was soaked in dirty water, and the tears on her face made her look particularly wolfish.

She ran to the corner of the corridor, gasping for air and tears streaming down her face because of extreme fear.

With a crack, a bolt of thunder struck. Under the illumination of lightning, Hinata Hajime could clearly see Tomikawa Yuki trembling constantly, with no life in his empty eyes.

"Have you been bullied again?" Hinata Sou came closer, took off his coat and put it on Tomikawa Yuki.

Maybe because she had been locked up for too long, Yuki Tomikawa's body felt as cold as ice.

Being trapped in the stadium warehouse on a rainy day, soaking wet, made Hinata frown constantly.

"Thank you, thank you Mr. Hinata, your clothes will be dirty." Tomikawa Yuki refused, with fear in her eyes, "I'm sorry, I can't do this, I, I'm fine, I'm really fine!"

"But you're really cold. It's okay, just put it on first." Hinata Hajime forcefully put the coat on her.

Tomikawa Yuki looked at Hinata Hajime with trembling eyes, then nodded gently, "I, I will wash the clothes very clean and return them to Mr. Hinata!"

"I told you not to worry about it." Hinata Hajime squatted beside her, "Have you always lived like this?"

Tomikawa Yuki shook her head vigorously, but the tear marks on her face made this denial seem particularly unbelievable. Hinata Sou sighed, he looked at the time, and then looked at the girl who was still sitting on the floor and shivering, "Have you had dinner?"

"Eat, eat an inch!"

But just as she finished speaking, Yuki Tomikawa's stomach began to growl.

Yuki Tomikawa quickly covered her stomach, she lowered her head, and her wolf-like face was flushed with embarrassment.

It really looks like a sin tree.

Hinata Sou really couldn't just leave her alone. She was subjected to such level of school violence, and her teachers and parents didn't care?

"Where is your home? Can I take you home?"

"No!" Yuki Tomikawa quickly refused, and then she lowered her head quickly as if she had reacted, but Hinata Hajime still saw her pale face.

"I'm sorry." Tomikawa Yuki cried and apologized again, "Although I really don't know what's good for me, but please don't send me home. I'm sorry."

Hinata Hajime looked at her, "No one says that about you."

"Since you don't want to go home, I'll take you to dinner first. There should be some restaurants open at this time."

"This is too much trouble for Mr. Hinata. I, I don't need to eat."

"Who doesn't need to eat?"

In the end, he still forced Yuki Tomikawa to go out. It was raining outside, and Hinata Hajime gave the umbrella to Yuki Tomikawa. Although Yuki Tomikawa should change her clothes now, she was very reluctant to go home, and was even more unwilling to buy a new one, so he had to let her go out wearing his coat.

Fortunately, Yuki Tomikawa is not tall, only about 1.5 meters tall, and wearing Hinata Hajime's coat is like wearing an overcoat.

Considering Yuki Tomikawa's personality, she would probably be more afraid of coming into contact with strangers after encountering such an incident. Hinata Hajime took her to an eel restaurant and asked for a private room to separate her from the diners around her.

In the warm environment of the store and the aroma of eel rice, Yuki Tomikawa finally calmed down and was willing to talk to Hinata Sou for a few more words.

"After Miyo disappeared, those people became more and more aggressive. I didn't know what to do. If it weren't for Mr. Hinata, I would have been scared to death." Tomikawa Yuki grabbed the cuff of Hinata Hajime's jacket, "I'm sorry, I will make sure to wash the clothes extra clean."

Hinata Hajime looked at her, "Why do you keep saying sorry?"

"Because, because... Mom said that this happened because I did something wrong, and that I must apologize before everyone will forgive me." Tomikawa Yuki lowered her head, "But no matter how I apologize, no one will forgive me, and they will continue to bully me."

"Mida told me that I shouldn't apologize and that my mother was wrong, but she thought I had learned a bad lesson."

[It's hard for me to imagine what kind of people her parents are.] Hinata Hajime frowned slightly, [Why is it her fault that her daughter is bullied at school?]

You don’t need to understand everyone.

Watching Tomikawa Yuki eat the eel rice bit by bit, she finally relaxed, and Hinata Sou spoke, "Can you tell me more about Chida Midori and Mouse Castle?"

"Miyo and Mouse City?" Tomikawa Yuki was stunned for a moment, "But, I didn't go to Mouse City."

"What about Chida Miyo?" Hinata Hajime asked, "Do you know the situation at her home?"

Tomikawa Yuki frowned slightly, and after a moment she spoke timidly, "She seems to be from a single-parent family. Her mother died of illness very early, and only her father is left. Her father came to the school because Midori was bullied, but this only made those people bully Midori even more."

"I don't know anything else."

Hinata Hajime avoided looking directly into Tomikawa Yuki's eyes so as not to increase her nervousness.

but……

[I remember that Yuki Tomikawa and Miyo Chida have always been good friends. Don’t they know each other’s family situations? Yuki Tomikawa has never been to Chida’s house? ]

【It doesn’t make sense.】

[Yes, Chida Miyo invited Tomikawa Yuki before leaving. She would not have completely concealed her family situation. There must be something going on.]

【She forgot.】

Hinata Hajime raised his head slightly.

She forgot.

What if the secret that Yuki Tomikawa went to Mouse City to clear up was about Chida Midori's family?

She was troubled by this secret and didn't know how to help Chida Midori because she was also trapped in pain and couldn't get out. The strong sense of guilt made it difficult for her to breathe. Finally, she decided to enter the Mouse City and clear up this secret. So she forgot Chida Midori's family and forgot that she had ever entered the Mouse City.

[Izuru, when we met Yuki Tomikawa before, she told us that Chida Miyo was inviting Yuki Tomikawa to enter the Rat Castle, right?]

【That’s right.】

That's right.

Chida Midori was not the origin of Mouse Town, but she encountered Mouse Town.

The source of despair is someone else.

Hinata Hajime took a deep breath and began to test Yuki Tomikawa in front of him.

"Student Fuchuan, what do you think of Rat City?"

"...Miyo, Miyo must be in the mouse city."

Hinata Hajime finally looked Tomikawa Yuki in the eye, "Why do you think Chida Midori must be in Rat City?"

"Huh?" Yuki Tomikawa was stunned for a moment.

"Chida Miyo, why couldn't she have left?" Hinata Hajime said, "After all, if she stayed here, she would be bullied and hurt by those people. Her father passed away, so leaving is the best choice."

"No, Midori didn't leave!" Tomikawa Yuki stood up subconsciously, with fear and panic in his eyes, "Miori will not abandon me, she is in Rat City!"

"Because……"

Hinata Hajime looked at her, "Because why?"

"Because I heard Midori's voice, because she told me about Rat City before she left, because, because..." Yuki Tomikawa's voice was trembling, and her tears flowed even more fiercely.

Why? Why did she feel that Chida Miyo was always there.

Why does her heart feel like it's being stabbed with needles whenever she thinks about this problem?
