Maronne first interacts with Reid Hershel, Farah Oersted, Meredy, and Keele Zeibel by attacking them after they settle down for the night. In the confusion, she kidnaps Reid on her drake, Barossa, where she coerces him into joining her on a bounty to defend the city of Belcagne on the Belca Island from the sea demon menacing it. The ruler of Belcagne, Excia, entreats them to stay in her mansion overnight, which Maronne accepts. As they rest, Maronne apologizes for the rough treatment and reveals that she has been following the group since they left Inferia Castle and that she needs Reid's help. Reid agrees to go on this hunt together with her. The two swoop after the others, antagonize their target, and slay it in one combined blow. Maronne parts ways with Reid at the port, though she remains in Belcagne.
