Flynn Gilbit (フリン・ギルビット Furin Girubitto) is the ruler of Caloria. She was married to Norman Gilbit six years prior the series, but he died in an accident three years ago and so she had disguised herself as him to prevent the territory from being taken over by Small Shimaron.
Flynn chose to wear a mask and pretend to be her late husband, Norman Gilbit, because if she did not Small Shimaron would take over the land and Caloria would no longer exist since under their laws; women cannot inherit lands or titles and adoptions are only valid before the death of the current ruler. Upon discovering that Big Shimaron has one of the Forbidden Boxes ("The End of the Wind"), she assists Yuuri and his group in retrieving it.
- She promised to Yuuri that Caloria always will be an ally of Shin Makoku and she will be always her friend.
