A-drug: What a Huge Scapegoat!

Ai Haibara actually wasn't sure about this either.

If it was just his true nature showing through, that didn't quite make sense either.

After all, this guy had previously been a chuunibyou High School Detective who shouted, "There is always only one truth," at the drop of a hat.

Had shrinking his body made him completely let loose?

How strange...

Even if he had let loose, it shouldn't have reached this extent, right?

Could shrinking down really let him seamlessly switch to a child's personality?

That didn't make much sense either...

With that thought, Ai Haibara lowered her gaze and sank into thought. "Could APTX4869 have the side effect of mental regression?"

There had still been too few clinical trials after taking APTX4869—people either died or turned into children.

So far, the only known successful cases on the list were her and Kudo.

Thinking it over carefully, it wasn't impossible. After all, if the body shrank, the organs would naturally regress as well. Hormone secretion would decrease too, and there would definitely be an effect on the brain.

But why hadn't she...

Uh, maybe there had been a tiny little bit?

The little loli's thoughts suddenly became clear.

No, she had never deliberately pretended to be a child!

She, Ai Haibara, was completely genuine!

It was all the drug's fault.

She, Ai Haibara, absolutely had to personally observe the subsequent side effects of this drug properly!

Then
