The key. Though the gacha had coughed up its fair share of odd items, this one didn’t seem to have any significance to any of you. And if that wasn’t hint enough, once the key was in Vinzent’s hands you could finally make out the exit door, just beyond the large “gumball machine” itself.

“Youuu fouuuund THE EXIT KEY! B-but–”

“Oh, congratulations! Now we don’t gotta hang around this pigsty anymore!”
They wound around towards the exit themselves and waited. With Neko-Neko’s approval, there was officially nothing keeping you from proceeding to the next car, aside from the addictive personalities among you, perhaps…
…And Abel, still sprawled on the ground at risk of shock. Though the running water in the summon-a-bathroom was great, you’d yet to find any actual medical supplies to help While it seemed those of you who’d rushed to his aid had things mostly under control, there were only so many first-aid supplies you’d all come here with. How long would they last? How long would he last, if the next car presented any danger? Surely you couldn’t risk staying behind long enough for him to recover fully—not with such an unreliable source of necessities—but if you just made a few more pulls at the gacha…

“I-I’m sure if you keep trying you’ll find something that can help him! I’ve seen painkillers, I’ve seen splints, I’ve seen bandages…”
But even if that was true… What difference would more treatment make in the end, when you were all in fear for your lives? Maybe it was better to leave Abel here—after all, he’d already proven a little violent under pressure. If this killing game continued, could you really trust him in your midst? Or would he make a tempting victim, with his injury? Maybe it was the wiser decision for everyone if you just left him behind.
Could you? Would you?
