[AI Mystery Manga: Live-Action Version] Episode 38: Midnight, Why Did the Numbers Jump in an Instant? — The "Full-Hour Early Departure Problem" Exposed by the Jumping Hour —

COMMIT GINZA / AI Mystery Manga: Live-Action Version / EPISODE 38

"I returned the watch and left at 11:59 PM." However, the evidence photo showed the time window reading "10." Was it the watch that skipped an hour, or the owner's account that was off? Kenji and the Appraiser pursue the mystery of a watch that vanished during a late-night exhibition and a final hour that seems strangely long.

① A little earlier, "12" suddenly appeared during the midnight demonstration

Shortly before 12:00 AM, Kenji and the Appraiser were at the central demonstration table. Toyama placed a silver wristwatch with a small window at the 12 o'clock position on the tray. The window showed "11." The blue center hand was advancing along the minute scale on the outer rim. It was a demo model of the same type, different from the stolen JH-38 unit.

As the hand reached the 12 o'clock position, the digit in the window snapped to "12." Kenji leaned in. He looked like he was waiting for "13" to appear next, but naturally, the watch didn't wait for him.

② You can read the time perfectly even without an hour hand

12:08 AM. The cleaning crew found an empty pedestal in a different section. Toyama opened the lending ledger and contacted Katagiri. The photo he sent, having already left the venue, was labeled "11:59 PM return photo." The pair, having finished their demonstration, also examined the photo.

③ Katagiri was the last person to borrow the watch

The JH-38 managed by Toyama had been in its display case until around 10:50 PM. Katagiri requested to borrow it, saying he wanted to "take close-up shots for the closing report," and followed formal procedures. When handing it over on a white tray, Toyama confirmed the management number on the case back and recorded the borrower and purpose in the ledger.

It was to be returned to the display case in the back. Katagiri had an operations pass that could open and close the cases. However, it was a rule that all staff participate in the post-event inspection. Simply sending a photo does not constitute a completed return.

Toyama replied that she had not stopped the watch or changed the time when it was lent out. However, she did not know if it had been tampered with after it was checked out. The Appraiser wrote that discrepancy on another line of his notes.

④ Around 12:30 AM, lining up the three accounts

Katagiri, asked by the hotel to explain the situation, returned around 12:30 AM. He carried a thin, black document bag over his shoulder. Kuroda, the head of security, attended as Toyama and Katagiri gave their accounts. For some reason, Kenji was busy writing down his own expected clock-out time on a piece of paper.

Toyama was at the midnight demo table. Kuroda was in the security area by the staff entrance. Both of their actions could be verified on the footage from that time. Katagiri, on the other hand, just kept repeating his own claim that he "was there until the end" and pointing to the photo.

⑤ If it was "11:59 PM," the window should say 11

The Appraiser used the midnight demo record and the sample watch to confirm how to read the display. Katagiri's photo showed "10" in the window and the minute hand near the fifty-nine-minute mark. According to normal operation of this watch, that combination corresponds to 10:59 PM.

These three are examples of the display when the watch is set to the correct time and running normally. Because it's a 12-hour display, the window would show "10" at 10:59 AM as well. The number in the photo alone cannot tell you if it's day or night, or what day it is.

⑥ Calling him the culprit just because of the "10" is still too early

Kenji started to rise from his chair. The Appraiser gently pushed his shoulder back down. A malfunction, a delay, time adjustments, image tampering—you can't rule these out with just one photo. Some actual models require caution regarding the first switch after manual adjustment.

The Appraiser asked Kuroda to let him see the original footage from the 10 o'clock hour, not just before midnight. The window in the photo didn't tell him the answer; it just broadened the range he needed to search by an hour.

⑦ The exit server didn't know about "12:05 AM"

What Kuroda checked was not the attendance report submitted by Katagiri, but the records remaining on the entry/exit server at the staff entrance. The departure process using Katagiri's pass took place around 11:05 PM. That's an hour earlier than he claimed.

Of course, the pass record alone doesn't prove he personally left. Kuroda opened the raw camera footage from the same time, verified Katagiri personally leaving through the entrance with a black bag after scanning his pass. Without relying on the watch display, his actions were linked through a different system of records.

Kuroda showed the results of checking the discrepancy between the recording system time and the venue's standard time. He also cross-referenced entries by other staff in the 11 o'clock hour and footage from before and after the midnight demonstration. Katagiri's account wasn't the only one off by an hour. He was checking the original footage, which was continuous, not short edited clips. There was also no record of Katagiri returning after leaving the staff entrance before the midnight closing. Kuroda stopped the screen after confirming the point where Katagiri was called back and returned.

⑧ Locking the door is different from returning the watch

There was no matching record of the display case being unlocked at "11:59 PM." The case was opened and closed with Katagiri's authorization about an hour earlier. Continuous footage of the display area showed Katagiri opening the case, holding the watch in front of the pedestal, and holding up a smartphone.

The position of the pedestal in the background of the photo and the reflection of the lighting behind him also corresponded to that moment of photography. They hadn't checked the photo to prove a delayed switch; they checked it to cross-reference his actual actions seen on camera with the sequence of his statement.

However, there were moments when Katagiri's body hid his hands, and the moment he put the watch into his bag was not captured. The Appraiser didn't explicitly claim he "stole it at 10:59 PM." There had been no other unlocking of the case between that locking and the 12:08 AM inspection, nor any signs that a return procedure had been re-attempted. What was certain was that his claim of having stayed until midnight did not match the records. And that the locking record could not substitute for a physical confirmation of the return.

⑨ The one-hour lie is clear. But where is the watch?

The Appraiser looked at the black bag on the edge of the desk. When he borrowed it, when he left, and now that he had returned—Katagiri had the same-looking bag. However, his actions outside the venue were not captured by the venue cameras. Footage alone couldn't prove the watch had been inside it the whole time.

Kuroda readied his recording camera. Until Katagiri himself opened the zipper, the two didn't reach for the bag. What came out of the inner pocket wasn't documents. It was a soft black pouch, and inside it, the silver watch.

⑩ The JH-38 on the case back answered the rest of the return photo mystery

The Appraiser took the watch with his white-gloved hands and turned the case back toward the recording camera. Management number "JH-38." It was the same number, same appearance, and same unique small scratches as the original close-up shot taken before it was lent out. It wasn't a same-model substitute that was found, but the vanished display watch itself.

The hotel secured the watch and records, turning them over to the operations manager. They didn't just end it with Katagiri's confession; they preserved the physical evidence results and each record where his statement had contradicted the facts. It was a much more painstaking follow-up process than the watch's digits jumping.

After the incident, Kenji tries to make his own clock-out "jump"

Back to help clean up, Kenji advanced his own watch by an hour and flashed it from his sleeve. Next to the watch was the midnight snack plate he had finally secured. His expression was more dignified than Katagiri's just a moment ago.

Conclusion: When the numbers jump, don't let your deduction jump too
