The World is Still Beautiful anime
The Sun Kingdom is a place where sunshine is a part of everyday life, while rain is something they’ve never heard of. In a distant land called the Rain Dukedom however, the weather is reversed and everyone has the ability to make rain with their voices.
In the three years that have passed since he was crowned king, Livius Ifrikia has conquered all of the world and increased the influence of the Sun Kingdom. Livius learns about the power to create rain and decides to marry Nike Remercier. However, rumours circulating outside the Sun Kingdom claim that Livius is a cruel and ruthless ruler. The princess begins to prepare for the worst. Nike finds out that her fiance is a completely different person than she had expected when she meets him.
