Two sisters, two opposite temperaments, one world depending on them. The show doesn't waste time on chosen-one flattery, it builds Fine and Rein into people you actually want to follow by making them argue, mess up, and learn that saving the world works better when you stop fighting each other. The opening moves slow, but once it clicks, 51 episodes of genuine character growth and quiet kindness becomes the most binge-able magical girl comfort watch in years.

Fine and Rein are twin princesses living in the Kingdom of the Sun, which sits at the heart of a hollow world where seven separate kingdoms depend entirely on its light to survive. Known as the least princess-like royals the planet has ever seen, the pair find an odd elevator that carries them down to the core of the Sun's Blessing. There they meet Princess Grace, who once gave everything to keep the sun from going out. Now its light is dimming again, and if it fails, every kingdom will fall into darkness. Grace grants the twins the power of Prominence and a spirit guide named Pumo so they can help the people of their world, but they must pass a test before they can save the light. The mix of comedy, fantasy and magical girl adventure runs across 51 episodes.
