As the others drew closer, Tsukamoto Kazumi asked:

Where did you go just now?

"I was just looking for you."

"My stomach was a little uncomfortable today, so I took the afternoon off and stayed in the infirmary to rest."

After answering the question, Shigu Guofan asked:

"What do you need me for?"

After hearing the reason, Tsukamoto Kazumi said:

"It's nothing important, we can talk about it next time."

"You should go and rest first."

As the "school doctor," after the two finished talking, Araide Tomoaki asked a question:

How are you feeling now?

"Has it gotten better?"

"I'm feeling better."

After saying this, Shigu Guofan bid farewell to the group:

"Then I'll go rest for a while longer, and then go home."

"So that I don't end up being sent to the hospital by that fussy doctor later."

Upon hearing this, Shinichiro frowned slightly.

He wasn't angry because Shiko Kunihiro called him a "worrier".

However, he suddenly had a feeling.

During his absence, the bad guy who was impersonating him not only didn't do anything bad at school, but also did many good things.

He had this feeling when Tsukamoto Kazumi mentioned it before.

After encountering Shigu Guofan, this feeling became even stronger.

He didn't think about it too deeply, even after pulling his thoughts back.

Seeing that the two knew each other, Sonoko asked:

"Kamisaki-senpai, was that upperclassman you and Hosaka-san's classmate?"

"No, they're from another class."

After shaking her head in denial, Tsukamoto Kazumi said:

"However, I heard that he and Hideaki Hosaka grew up together."

"Oh." Sonoko nodded knowingly.

The group climbed the steps and headed up to the library.

Taking advantage of the moment when everyone's attention was elsewhere, Conan quietly told Kōyū what he had discovered:

“I just found what looks like a signature on that table.”

"I don't know if it's related to these paranormal events."

There's just a signature on the table.

For students, this is a very ordinary thing.

In addition, they also drew on textbooks, especially on pictures of famous people.

For example, drawing arms on celebrities whose portraits only show their upper body, making them playfully make a peace sign or something.

Most students have probably done this kind of thing.

There's nothing strange about it.

But Conan, as a detective, cannot overlook any detail.

Even the most ordinary things might be the key to solving a case.
