Otona no Bouguya-san (Rimen)

A suspicious new shop opens directly opposite the adult armor store and immediately begins stealing its customers. Curiosity gets the better of Kautz, and a bizarre purchase from the newcomer reveals that the place is far more than competition: it is an entrance to other worlds where the usual rules no longer apply.

Kautz, Liletta, Narden, the Demon Lord, and their companions are drawn into dangerous worlds of traps and madness before returning to face a new threat to the business, the mysterious idol D. Emina. If flashy equipment can sell armor, the shop's answer is obvious: fight an idol with idols, no matter how ridiculous the result becomes.
