Subaru:  Even with his stupid jokes, Subaru was at last able to make her smile. If all of this turned out well, he would like to see that smile again, in a brighter place. “All right. Will it be a snake or a demon that pops out this time? Given the fantasy setting, neither option is one I can just laugh off…” Subaru joked to himself, and with lagmite in hand, he carefully made his way into the cellar.

Subaru:  In the dim light, Subaru could make out a counter in front of him, across from the entrance. The building must have originally been something like an inn. It looked as though they were using the first-floor bar area without any major changes. On top of as well as behind the counter—which was probably serving as something like a reception desk—Subaru could see a lot of different items cluttered close together. There were small boxes and pots, swords and cheap metallic objects, and many other varied items. It was clear that all of these were stolen items, based on the wooden tags that were attached to all of them.

Subaru:  “The way the system works, if you rounded up all of these wooden tags and handed them to the guards, it looks like they could arrest everyone at once…” However, as was usual with this line of business, there were probably some connections between this place and the not-so-upstanding citizens who offered support. Subaru was suspicious of where most of these stolen items ended up.

Subaru:  Subaru ventured farther into the cellar, looking for Satella’s badge. But just then…

Subaru:  “Hmm?” Subaru suddenly stopped, feeling something strange under the soles of his shoes. It didn’t feel like he had stepped on something hard; it was actually the opposite. Like the ground he had stepped on was clinging to him; like there was something sticky on his shoes. He raised his foot, and touched the bottom of his sneakers. He felt some sort of fluid, something strangely sticky that clung to his fingers, stretching as he pulled them away. It was something that instinctually made him feel uneasy.

Subaru:  “What is this…?” Subaru brought his fingers close to his nose and tried to smell it, but because of the stagnant air inside the building mixing with it, he couldn’t quite pin it down. Unsurprisingly, he didn’t have the courage to try tasting it. After wiping the rest of the substance on the nearest wall, Subaru, urged on by a feeling of unpleasant dread, put the lagmite out in front of him and started forward.

Subaru:  Then, he found the source of the slime.

Subaru:  “…Wha?” Subaru unconsciously let out a foolish sound as he looked on. In the small visible range of his light, what he first saw lying limp on the ground was an arm. Its hand’s fingers were reaching out as if to grab something, but the other end of the arm, at the elbow, was missing the body it should have been connected to.
