Fushigiboshi no Futagohime

There exists seven kingdoms within the Wonder Planet. The Sunny Kingdom is home to Princess Rein and her twin sister Princess Fine. The planet lived in peace until one day the Blessing of the Sun began to fade. If the Blessing goes out all life on the planet will perish! Princesses Rein and Fine are bestowed with the power of Prominence to help save their planet, but will the two most "un-princess-like princesses since the beginning of the Wonder Planet" be able to master such power and save their planet?
