Flame Kingdom ☆ Prominence on Empty Stomachs is the second episode of the Fushigiboshi no Futagohime anime series.
Fine and Rein go to the Flame country. There, Fine wants to eat the Flame fried rice really badly. She and Rein go to this restaurant, only to find it closed. It turns out that the owner of the restaurant can't make the Flame fried rice anymore because the volcano, where the spice is gathered, has not erupted in a long time.
