The world always deceives you with false dreams.
It’s okay now, it doesn’t have to be perfect.
Did you enjoy the dream I made?
Tomorrow, which no one knows how many more there will be, will come again.

Two hundred years ago, there was a small, beautiful country in the depths of the forest, but it disappeared due to invasion. As a descendant of that country, Luna is revered around the world as a symbol of deterrence of war and justice. Although in reality she is just an ordinary child, she has been used in wars as a psychological attack and propaganda due to the many superstitions people have created about her, and the deaths resulting from shock of those who have seen her divine appearance.
 
The reindeer was merely set up to always be by her side to dramatize her sanctity, and young Luna was always afraid of the big creature. However, the reindeer had a gentle nature and loved her, and never hurt her, so Luna was able to let her guard down little by little over time.
