Hysteric Kingdom

[It is difficult to define what a normal afternoon is by Netherworld standards. In the dark, torch-lit halls of the Overlord's Castle, penguin-suited prinnies totter about pretending to do work, while most other vassals make no effort at all to pretend. No fights have broken out yet, but it is questionable how long that will last with the Overlord being awake. It is just the sort of calm that comes before something unexpected happens, or someone makes it happen out of boredom.

And that is precisely when the first stranger comes through the swirling vortex of the Dimensional Gate.

It doesn't seem so unusual at first, because people use that gate on a daily basis. But more people start to show up, people who aren't demons. The Gatekeeper herself has no idea where they've come from, or how they've found their way to the Netherworld.

Unfortunately, neither do the unexpected guests.]
