Though I Am an Inept Villainess: Tale of the Butterfly-Rat Body Swap in the Maiden Court Novel Volume 8 was written by Satsuki Nakamura with illustrations by Kana Yuki.

Having learned that the emperor is rooting out forbidden magic, Shu Keigetsu and Kou Reirin return to the palace with the body swap still in place. Their next idea is to undo the switch during the Repose of Souls—until the emperor foils their plans yet again! He sends the Maidens to the kingdom's border to dish out food on a charity mission. Moreover, Reirin is assigned a particularly inhospitable area far from Keigetsu and the others! Can the girls make it through this ordeal without falling back on Keigetsu's magic?
