The Party Saves Hortensia

After becoming brainwashed by Zephia in Chapter 14, Alear and her troops (including Ivy, Elusia's princess in exile) are forced to fight her. Fortunately, they snap her out of the possession after beating her up. While initially hesitant to join the party, Hortensia is eventually convinced by Ivy and Alear due to them telling her that Elusia isn't currently under either Ivy or Hortensia, due to their father, Hyacinth being murdered via being devoured by Sombron, who basically usurped control from the royals and returning would only make Hortensia a puppet for Sombron and the Four Hounds' schemes.
