Flame Kingdom ☆ Prominence on Empty Stomachs

Sweetest Smiles ☆ Twin Princesses is the first episode of the Fushigiboshi no Futagohime anime series. It is also the first episode of the season.


Princesses Fine and Rein are the princesses of The Sunny Kingdom. A Best Princess Dance is held within the kingdom and princesses from all seven countries come. Prince Bright of the Jewelry Kingdom is also introduced, along with The Flame Princess, Lione. The twins meet Princess Grace, the princess who passed saving the seven countries from the darkness. They also learn how to use the Prominence.


The episode starts at the Sunny Kingdom, where the preparations for the upcoming Princess Party is currently underway. Camelot and the maids of the castle are desperately searching for the twin princesses Fine and Rein, until Camelot finds them right on the roof, watching the hot air balloons from all the kingdoms of Wonder Planet entering in their kingdom. Camelot has had it and yells at them to return inside and welcome the guests, though it doesn't work.

Immediately, a girl flees it from her ballon, it is revealed to be Lione, the princess of Flame Kingdom. Fine and Rein run out to her and find out what's happening, and they both crash with Lione into a bush. The princesses introduce themselves. It is revealed that Lione is timid of dancing because she doesn't want to bump over her partners and getting humiliated in front of the crowd. Fine and Rein reassure her that this will not happen. 

A few moments later, Fine and Rein are moving on to get to the princess party before it starts. But once they reach the elevator, they are instead brought into an unknown place, which it is revealed to be the Blessing of the Sun. The twins are soon called in by Princess Grace, the former princess of the Sunny Kingdom who once saved the planet. Grace tells them that the floating sun's light is losing power, and gives the secret mission of saving the Mysterious Star by restoring the blessing's light on time to the twins, and sends Poomo, a fairy, to guide them as she gives them the power of the Prominence, which he will help them during their mission.

Later, the princess party starts with Bright, the prince of the Jewelry kingdom, dancing with all the princesses of the planet. Rein dances with Bright while Fine searches for food. The light suddenly goes out when it's Lione's turn to dance. However, thanks to Fine and Rein using Prominence to light up the castle's inside, Lione is able to dance with Bright, ending up winning the princess party as the best smiling princess. Meanwhile, a mysterious guy watches from afar.  

After the princess party, Fine and Rein are in their room, when Camelot bursts in. She informs the twins that they are going into a very strict lesson session to become well-educated princesses. Fine and Rein start running away as Poomo doubts if they can really save the Mysterious Star.
