Upon knocking on the door, a hidden slot within one of the horizontal panels of wood would be revealed and opened. From the slot a voice would speak sharply and swiftly: "Password?". Depending on Shio's reaction to this, one of two things would happen. If she correctly identified the password, the door would open to reveal the interior of the shop, and she would be beckoned inside by an elderly woman behind a counter at the far end of the shop. Failure to correctly identify the password would result in the slot being closed - though it would open again should she knock. If she failed multiple times, she would notice that the voice was identical each time that it spoke, as was the timing of opening the slot. It would be almost eerie how identical each separate instance was, should Shio experience it.
