Phos, Nemu, and Stella continue on their journey with their new cat-shaped companion. And her highness's followers appear out of nowhere to "ensure their lady's standards" and give the girls a special potion. Said potion immediately puts them to sleep where they enter a shared dream state and have a time-warped training montage.
Then they arrive at Engrassia, a town with branches of the Adventurer's Guild and the Western Holy Church... you know, the very anti-monster factions of this world. And their attempts to hide their monster natures are honestly kinda pathetic. It's like they don't understand "undercover mission".
Meanwhile, there's plotting and retribution happening around them, so be prepared for trouble.
