Yen Press has licensed the manga, and it will release the third volume in English under the name The Demons Are Planning Something Good on December 15th, 2026. Yen Press describes the manga’s story below:

“People don’t truly appreciate the amount of R&D that goes into making traps. I mean, you can’t let the heroes waltz up to the demon lord unscathed, can you? Do you know how much logistical work goes into keeping the traps armed? In coming up with new, innovative ways to scathe, maim, and humiliate the humans? From slime that melts your clothes to titillating tentacle traps, follow along with the Demon Lord’s underlings as they devise, concoct, and scheme up all new ways to strike fear in an adventurer’s heart.”
