You're Also Insane

"Maybe he's not mentally ill; maybe he's just a complete scumbag," Yumi Miyamoto said, gritting her teeth.

"That's not right."

Little Ai contradicted Yumi Miyamoto, which greatly pleased Guchuan Ning.

She truly is the sister I picked up; she's still on my side.

"He might be both mentally ill and a scumbag."

Guchuan Ning's face instantly darkened. Yep, she really is the sister I picked up.

"Are there any other abnormalities?" Fukuyama Shien asked.

"He also has a distorted perception of time," Little Ai said.

She genuinely felt that Guchuan was mentally ill.

If he wasn't mentally ill, how could he have misheard 'take me to the Kudo family home' as 'come home with you'? How could he go out alone at night to pick up a child?

After living with Guchuan for a few days, Little Ai felt he wasn't a normal person.

"What day of the week is tomorrow?" Fukuyama Shien asked, looking at Guchuan Ning.

"Sunday."

"Wrong, tomorrow is Friday." Fukuyama Shien became even more convinced that Guchuan Ning had a mental illness.

"Haha, maybe I misremembered. I don't have work or school, so it's normal to get the days mixed up, right?" Guchuan Ning said, feeling a pang in his heart.

Fukuyama Shien and the other police officers all looked displeased.

"Today is April 15th, what's the date tomorrow?" Fukuyama Shien asked with a cold expression.

Guchuan Ning clasped his hands together and pondered for a long time before slowly speaking.

"I have the right to refuse to answer."

"Heh, you really can't tell, can you?" Little Ai said leisurely.

Guchuan Ning really couldn't tell. There was only a one in 365 chance of getting it right if he just guessed, so the safest method was to refuse to answer.

"He really does have a distorted perception of time," Fukuyama Shien said, touching the few remaining strands of hair on his head.

"I don't know what's going on this year, but our Aoyama Mental Hospital has received many patients with distorted perceptions of time."

"Is it possible that they don't have a distorted perception of time, but rather there's something wrong with this world?" Guchuan said, staring at Fukuyama Shien.

"See, this is a classic statement from someone with a mental illness," Fukuyama Shien said excitedly.

"I told you, you really are mentally ill, Big Brother~" Little Ai patted Guchuan's back, a look of delight on her face.

"Mr. Guchuan, if you have time, please come to our hospital for an electroencephalogram. If you decide to seek treatment at a mental hospital, please prioritize our Aoyama Mental Hospital," Fukuyama Shien said sincerely.

"Heh, you quack."

Fukuyama Shien, who had been called a quack, wasn't angered. Could he possibly take seriously an insult from a mentally ill person?

Seeing everyone around him staring at him with curiosity, Guchuan felt anger surge within him.

"If this is how mental illness is diagnosed, then my sister, Loli Guchuan, she's also mentally ill." Guchuan Ning lifted Little Ai onto the table.

Conan couldn't hold back his laughter when he heard Little Ai's name, 'Loli Guchuan'.

"Conan, be polite, don't laugh at people," Ran said, swatting Conan's arm in displeasure.

"I understand, Ran-neechan."

Little Ai looked at Guchuan blankly, unsure what this mentally ill person was going to do.

"Step one, horizontal comparison: assess the patient's differences from normal people around them." Guchuan pulled out his smartphone and opened his photo album.

"Other children like dolls, but she likes designer bags."

Guchuan Ning showed the photos to Fukuyama Shien. The phone displayed pictures of Little Ai holding fashion magazines.

"It's just that her interests are different from other kids; that's not a mental illness, is it? My Conan is also different from other kids," Ran said gently.

Conan chuckled twice.

He wasn't a real elementary school student, so of course he was different from them.

Little Ai angrily snatched Guchuan's phone. She wasn't bothered by being treated as mentally ill, but she was furious that he had secretly taken photos of her!

"You pervert, who told you to secretly photograph me?"

"What 'secretly photographed'? I clearly took these openly; you just didn't notice," Guchuan Ning retorted, completely unashamed.

"Police, quickly arrest this pervert!"

"Big Brother is just taking photos of his sister to document her life."

Little Ai's face flushed as she checked the photos on the phone, sighing in relief when she didn't find anything inappropriate.

However, she couldn't go back to that house.

"Officer, I want to report him! This guy is a pervert who lures children," Little Ai said, running up to Inspector Megure.

"Little girl, didn't you say yourself earlier that you're Guchuan Ning's sister?" Yumi Miyamoto crouched down and patted Little Ai's head.

"I take back what I said earlier. I am not that scummy pervert's younger sister."

Yumi Miyamoto just assumed it was a sibling squabble and patiently tried to comfort them.

Meanwhile, Guchuan Ning was discussing his younger sister's condition with Fukuyama Shien.

"And she really likes to imagine she's an adult woman with a super high IQ. She acts like an adult every day, and loves to lecture me, her older brother."

"Haha, your little sister is really cute," Fukuyama Shien said with a laugh.

"How can you be so biased?" Guchuan frowned, clearly displeased.

"Huh?"

"When I'm not normal, I'm mentally ill, but when my sister's not normal, she's cute? Is there any logic to that?"

Fukuyama Shien wiped the spit off his glasses and patiently appeased his patient.

"It's perfectly normal for children to like to fantasize. Didn't we all imagine ourselves as saviors when we were little?"

"I didn't."

"Are you trying to argue?"

The conversation was going nowhere. Fukuyama Shien felt his patient was having an episode.

"I'll suggest to Mr. Guchuan Yuan that he send you to a mental hospital for treatment."

"I'm perfectly healthy."

"According to your sister and Ms. Yumi Miyamoto, you've already exhibited behaviors that are dangerous to society. If you don't get treatment soon, you might do something even more outlandish," Fukuyama Shien said.

Little Ai nodded repeatedly as she listened.

Guchuan really should be locked up in a mental hospital, though prison might suit him even better.

"My sister also has a mental illness. I'm going to the hospital with her," Guchuan said, staring at Little Ai.

"I don't have a mental illness!" Little Ai shouted.

"Mentally ill people always say they don't have a mental illness," Guchuan said with a sympathetic pat on Little Ai's head.

"Well, I just don't," Little Ai glared fiercely at Guchuan.

"Little sister, my mental illness might be hereditary, so you definitely have it too," Guchuan stated with certainty.

"What does family heredity have to do with me?"

"Well, my mental illness is contagious, so you just do have it," Guchuan said unreasonably.

"You lunatic!"

Furious, Little Ai stomped on Guchuan's foot.

"See? You're already showing violent tendencies, and you still say you don't have a mental illness!"

Conan looked at everyone discussing mental illness, wanting to speak but hesitating. Shouldn't they have been discussing Guchuan Ning's theft just now?

Finding the culprit before him and stealing the armor was very…

Wait!

A lightbulb went off in Conan's head.
