I adopted a child demon from the Gap, and I'm a special agent for the Bureau of Supernatural Ab

Such words...

“You said it, didn’t you, Emiya?” interrupting Kiritsugu Emiya, Li Cheng raised his head and looked at Kiritsugu Emiya seriously, “You said that you had given up that path for the sake of your family.”

"!"

Startled, Kiritsugu Emiya froze on the spot. Without realizing it, he had developed a murderous intent towards the young girl he had only met once. This was truly... this was truly...

"……Feel sorry."

Finally, that was all he could say, his voice hoarse and low.

"fine."

Reaching Kiritsugu Emiya, Li Cheng gently patted him on the shoulder. He understood the other's obsession and knew how difficult it was to let go of everything. Of course, in reality, they hadn't completely let go, since they were still members of the violent organization that maintained order, just not as extreme as before.

"It's alright, we're friends, there's nothing wrong with saying these things. Don't put too much pressure on yourself. Kiritsugu, tell me your plans. I'm not a smart person, but I know that this girl is likely involved in something big. You make the decision."

"Ok."

Nodding, Kiritsugu Emiya's expression turned serious again.

I've been writing this for four days now, but those twisted, bloody, and terrifying inspirations still pop into my head from time to time. It's really hard to choose...

Section 6, Chapter 5: Pleasant and Unpleasant Relationships

Li Cheng originally thought that Kiritsugu Emiya would take the girl away, whether to hide her in a safer place or to conduct a more detailed analysis. In short, he thought that this difficult brat could finally leave.

However, Kiritsugu Emiya refused!

"She's doing well with you. In this place, with your strength, it wouldn't be so easy to take her away. Besides, you've spent so much time together, you must have developed some feelings for her, which I understand."

You don't understand anything!

That brat is so annoying, okay? She's completely unapproachable, her attitude towards him is awful, okay? She made a huge mess of his house, okay? And made him spend so much money to replace so much furniture, okay?! That jerk has absolutely no feelings for me, even though I've been eating and drinking for free for so long, she still treats me like an enemy and is wary of me!

Although that's what I really wanted to say...

"I need to investigate thoroughly what might be hidden behind that girl, and it won't be an easy task. During this time, she might attract enemies, and we're currently in this rather awkward situation of being 'suspended from duty.' After much thought, I can only trouble you for a while longer. I'm sorry."

Li Cheng couldn't think of a reason to refuse such a serious request. Besides, although the girl was troublesome, he had at least taken care of her for so long that he could manage. If he suddenly moved her to a new environment and made her face strangers, it would probably be chaos again.

Yes, that's right. My friend Emiya asked me to take care of her, and I didn't want that brat to bother anyone else, so I reluctantly continued to look after her. That's it.

Tsk, thinking about it this way, it makes me seem like I'm just taking advantage of Lei...

After Kiritsugu Emiya left, Li Cheng thought for a moment, then stopped by a convenience store and bought some desserts and snacks that children like, before heading home.

The uneventful days that followed continued.

Despite the mysterious background of "monster," it wouldn't change Li Cheng's attitude towards the girl. He had lived for some time and seen his share of ups and downs, so he wouldn't be easily swayed by her feelings.

The girl remained wary of Li Cheng, refusing to approach him or let him get close. However, compared to the initial panic and flight at the slightest provocation, she was now less sensitive. At least she wouldn't run away immediately unless Li Cheng deliberately approached her; well, she would still stare at him intently, her whole body tense.

The only good news is that she's stopped damaging the furniture so much. Perhaps Li Cheng's attitude has made her realize that she shouldn't destroy things so easily. In any case, unless Li Cheng tries to catch her, she won't knock over the furniture around her.

Furthermore, she did not attempt to leave again. In fact, she had not tried to escape for many days. Although she would watch Li Cheng's actions very carefully every time he opened the door, the dents on the door and the cracks on the window did not continue to increase.

Li Cheng and this monster girl began to enter into a strange way of life.

Li Chenghui would wake up promptly around seven o'clock in the morning, and the girl would wake up with the sound of his footsteps as he left the bedroom. Li Chenghui would prepare breakfast, as usual setting aside a portion for the girl, then go for a walk and buy groceries for lunch. After returning, he would collect the girl's clean bowl, turn on the TV so the girl would have something to do, and then do some exercise himself.

Lunch was the usual meal: cooking, eating, and setting aside a portion for the girl. Then came the afternoon nap, followed by waking up, collecting the girl's dishes, washing them, and repeating the same routine in the evening. This highly structured life was fine for Li Cheng occasionally, but after a while it became incredibly irritating, and he increasingly felt like he was raising a cold, aloof cat.

Incidentally, after discovering that the girl possessed the amazing ability to not excrete like a two-dimensional anime girl, Li Cheng also discovered that her body did not seem to get dirty or secrete oil. In other words, apart from her mouth and hands, which were often greasy from eating, the rest of her body was always clean. Even though she hadn't washed for many days, she just wouldn't get dirty at all.

She tore off the bandage from her previous injury a few days later, and the wound underneath had completely healed without leaving a trace. Li Cheng was slightly envious of her ability to leave no scars.

The attempts at communication were a complete failure; the girl was extremely wary of Li Cheng. Even something as simple as wiping the grease from her mouth required a half-hour chase, resulting in at least one piece of furniture being destroyed. However, after Li Cheng's determined persistence, and after being caught and forcibly wiped from her mouth for the fourth time, he noticed she began to imitate him, carefully wiping the grease from her mouth after finishing her meals.

Li Cheng was very pleased and carefully demonstrated to her how to use chopsticks, hoping she could learn. The girl did indeed watch his movements very attentively. However, after two days, Li Cheng realized that the expression on her face when she stared at him was similar to the expression on her face when she stared at the TV.

So, she's treating me like a performance artist?

Having understood the girl's attitude, Li Cheng got up dejectedly and left, but just before entering the kitchen, he heard the girl chuckle softly.

The voice was very faint and soft, and there was only one sound. Li Cheng was certain that he had not misheard. He turned around and saw the girl rolling around on the floor in the corner, pulling at the curtains above her, playing by herself.

No, I heard correctly. My ears must be working properly. That monster girl really did laugh just now.

Many days have passed since she was brought to this place, but this is the first time she has laughed. For a long time, she has rarely shown obvious emotions—the anger when being chased, her usual expressionless face, the occasional curiosity when she steals glances at him—but this is the first time she has laughed.

Is it really that funny to act like a monkey trying to use chopsticks in front of her?!

That brat is incredibly infuriating.

However, she doesn't seem to be as stupid as she appears.

Although feeling mocked was unpleasant, Li Cheng wasn't stupid. He immediately realized that this monster girl probably did have some brains. Considering his previous interactions with her, he felt he might have used the wrong approach.

The initial approach may have had some flaws, but a different approach might change the current situation where communication is impossible.

Looking at the girl again, he noticed she was also looking at him with some curiosity. Li Cheng thought for a moment, then gave her a friendly smile.

The other person didn't react at all, turned around expressionlessly, and continued playing with the curtains.

That... bastard!

Taking a deep breath and trying hard to calm himself down, Li Cheng suppressed the anger in his heart with great difficulty.

Then he heard a soft chuckle.

"whee--"

This time it was crystal clear, unlike the fleeting glimpses before. Li Cheng saw the girl lying on the brown wooden floor, covering her mouth, her deep blue, jewel-like eyes looking at him, letting out a thin, high-pitched laugh, her face beaming with happiness, just like most carefree children in the world.

For a moment, Li Cheng froze on the spot. The girl's smiling face seemed to overlap with a scene from the depths of his memory. He closed his eyes, and when he opened them again, the girl was still lying there, smiling at him.

It's almost like...

"Fool--"

Huh?

Did he just hear something?

"Fool--"

The voice was unmistakably that of a child, clear and sweet, the kind of voice that always brings joy to the listener. But that was detached from the content of her speech; I hadn't expected it, I really hadn't expected it. The monster girl's voice was pleasant, but what she said was another matter entirely.

"Fool--"

The third time, the girl spoke haltingly, her words not quite standard, but her face was beaming with smiles. Although her speech was still immature, her gaze and the words she uttered clearly conveyed her meaning.

You little rascal, I specifically chose children's programs for you to watch, and after so many days, all you've learned is "idiot," and you're even using it to insult me!

Unforgivable! Face judgment, sinner!

Unable to contain himself any longer, Li Cheng lunged at the girl who was giggling. Once again, the sounds of furniture collapsing and breaking, a man's roar, and a small, clearly provocative laugh echoed through the house.

Hearing another series of loud noises from upstairs, the old man adjusted his black-rimmed glasses, took a sip of strong tea, and sighed as he looked at the poetry collection in his hand, "These young people nowadays..."

What followed that night was that Li Cheng, at the cost of a large area of ​​the floor cracking and six pieces of furniture being destroyed, caught the girl and, in retaliation, tickled her feet for two whole hours, playing with her... punishing her until she cried.

In the far distance of the black sky, dark clouds began to slowly gather.

Section 7, Chapter 6: Changes on a Stormy Night

Li Cheng was very happy. He had finally succeeded in punishing that hateful monster girl severely. By tickling her toes, he made that arrogant and resistant girl cry.

Why do I suddenly feel like I'm such a scumbag...?

Sitting on the half-collapsed sofa, looking at the girl huddled in the corner with her back to him, occasionally sobbing, Li Cheng couldn't help but ponder.

Thinking about it carefully, pinning such a young girl to the ground and tickling her feet while she cried out did seem a bit like bullying. However, considering the girl's terrible behavior over the past few days, Li Cheng felt that he hadn't done anything wrong.

To be honest, seeing this indifferent little guy struggling and looking like he was about to cry, Li Cheng felt it was really great.

Then, Li Cheng finally realized what was happening.

She can talk?

This yokai girl, who doesn't get close to people and only makes simple cries, even needs repeated instruction to wipe her mouth clean after eating, can talk.

The scene from a few hours earlier flashed through his mind: the girl lying on her back on the ground, covering her mouth as she looked at him, chuckling softly, and stammering out the word "idiot" in a high-pitched voice.

She was clearly scolding him, but now that I think about it, she seems kind of cute.

No, wait, that's not the point! This girl definitely couldn't speak at first, and I didn't teach her. So, she learned the language by watching TV? No, not only that, she said that word to me, deliberately insulting me; she must have understood its meaning. In other words, without any instruction, she not only learned how to pronounce the language but also grasped its meaning.

This guy has such a strong learning ability, it's truly... terrifying.

Li Cheng now understood why the girl was so obsessed with television. She didn't actually enjoy watching TV; rather, she was using it to learn about the world and its languages. He couldn't help but feel grateful that he had always chosen wholesome and positive children's programs; otherwise, who knew what this blank slate of a girl would have learned?

Now that she can speak, how far has she progressed? Is she able to communicate normally with people?

Thinking this, Li Cheng called out to the girl:

"Hey--"

He shouted and waved at the same time.

"You probably only know how to say 'idiot,' right? What else do you say? Would you like to talk about it?"

The girl, huddled in the corner, slowly turned around, tears still streaming down her face, her deep blue eyes fixed on Li Cheng. The resentment in her eyes, like that of a neutered kitten, was so clear, a silent accusation against Li Cheng's previous brutality.

Even someone as thick-skinned as Li Cheng would feel ashamed under such a gaze. He tried to speak to her again, but the girl didn't respond at all, simply continuing to stare at him with resentful eyes.

Faced with such accusatory gazes, Li Cheng had no choice but to give up and stop trying to speak to the other person.
