Though I Am an Inept Villainess: Tale of the Butterfly-Rat Body Swap in the Maiden Court, Volume 5 (Though I Am an Inept Villainess: Tale of the Butterfly-Rat Body Swap in the Maiden Court #21-24)

The Maiden Court's blazing summer of plots and curses wanes into cooler autumn days. Keigetsu buckles down to restore the Palace of Vermillion Stallion in the turbulent wake left by the ex-Noble Shu, along with Reirin's bolstering support. That fateful Double Sevens night almost seems like a different lifetime, but the seasonal change also marks a big event—the Harvest Festival, a chance for the Maidens to trade the palace for the southern region, in none other than... Shu!
