Memory 34 (trivial neutral)

Sealing Kumasawa and Gohda's rooms in the guesthouse [EP5] Form of a miniature goblet, with a slightly less miniature glass vial. Fill the goblet and drink to receive your memory. 2/3 uses remaining.

"After all, it was an unsettling night, and a massive amount of gold had just been discovered. Many sorts of crimes might have occurred. ......Where there is a detective, there will be a crime. I foresaw that some kind of crime would take place, so I used this to seal away people whose alibis might otherwise be lost."
Erika held a small, folded piece of brown paper high in the air.
"After I watched Kumasawa-san, who returned to the guesthouse with me, say goodnight and enter the waiting room, I used this to seal the door. Then, in the morning, when the crime was discovered and caused a big uproar, I immediately went to check Kumasawa-san's waiting room, where I confirmed that the seal was still set. Therefore, I can prove Kumasawa-san's alibi!"
".........<Good>. A wonderful alibi. Not a single gap. Kumasawa returned to the guesthouse with Erika, went to the waiting room to sleep, and never left the room until morning. In other words, after Kumasawa returned to the guesthouse, she never went to the second floor until morning."
The proof Erika had shown was elevated by Bernkastel and became red truth.

This truth, which had become red, could no longer be covered up, even by Beato...

In other words, in that instant, Kumasawa's perfect alibi had been absolutely guaranteed.
"Hohoh! Then what about Gohda?!"
"Gohda-san holed up in the servant room right after reaching the guesthouse. I sealed him up in the same way. Then, when Rosa-san returned at 1:00 AM, I happened to notice her when I stepped out into the corridor. I let Gohda-san, who was still in the servant room, know this."
"At that moment, the seal was doing just fine, so from the time we arrived at the guesthouse until 1:00 AM, Gohda-san never left the servant room. And afterwards, he was with me in the lounge until 3:00 AM. And after 3:00 AM, I was on the second floor, so I can guarantee that Gohda-san didn't come up to the second floor."
".........Erika's seal proves that Gohda was holed up in the servant room until 1:00 AM. And Erika has proven his alibi from then until 3:00 AM because she was passing the time in the lounge with him. And Erika has also proven that he never set foot on the second floor until the morning after."
"In other words, after Gohda returned to the guesthouse, he never went up to the second floor until morning."

Notes
A pretty uneventful memory! Just doing what it says above, sealing the waiting room and then the servant room with duct tape seals. It won't have much effect other than more reinforcement on the best way to use duct tape seals (if there's likely to be a crime, prepare them, and seal people in rooms any time they are out of her sight so she can guarantee their location...)
