What is the plot of The Demons Are Planning Something Good?

While typical high-fantasy adventures focus on the brave heroic party storming the dark castle, this comedy turns the camera directly onto the lower-level dungeon employees. In this universe, humanity’s negative emotions serve as the crucial source of magical power for the demon army. Lord Mercy-Snare, the leader of the trap-building department, relies on humiliating and annoying adventurers to harvest this precious energy.

The story reveals that dungeon traps do not just spawn out of thin air:

• The R&D Department: Every classic fantasy trap, from clothes-dissolving slimes to target-binding tentacles, is the result of grueling research, testing, and bureaucratic stress by underpaid demon employees.
• The Twitter Origins: Creator Takuji Kato originally launched the project in 2022 as a series of short, self-contained comedic gag strips on Twitter before Kadokawa picked up the property for official serialization in 2023.
• The Workplace Comedy: Instead of epic bloodbaths, expect a comical office-place dynamic where demons deal with budget constraints, safety regulations, and the constant trial-and-error of creating the ultimate mildly embarrassing hazard.
