The first Akuyaku Reijou, Brocon ni Job Change Shimasu novel (English subtitle: This Reincarnated Villainess Is Living for Her New Big Brother) is so forgettable that, despite having read it less than two weeks ago, I remember next to nothing about it. The only thing that stuck with me is how the (centralized, here) unconventionally incestuous romance setup brought to mind Shujinkou ja Nai!.
Fortunately, the series‘ petplay aspects do not get much prominence in the second Zilbagias novel. Unfortunately, the event development has to go through some rather extreme contortions to thread the needle between the actions of a human hero and demon prince… and honestly doesn’t do all that good a job at it. Not thrilled by the ballooning harem either.
