La Croix is one of the monster reappearing in Monster Girl Quest: Paradox.
La Croix makes a small appearance at the end of part 2 in the Devastated Plains ruins, talking to Kagetsumugi about Black Alice. Luka's party along with Chrome stumble upong them, and Kagetsumugi leaves while La Croix send her Cirque du Croix to deal with the party. After beating them, La Croix tells the party that resisting is useless, but as Chrome hands down the notes from her other world's self, she realize there may be hope yet for the world and leaves the zombies to be taken care of by Chrome.
- Alice's mother had not "joined" yet the Cirque du Croix at that point.
