Santalia

The Princess of Hope and our protagonist. She came from the Land of Hope, and usually spends her time with an elementary schooler named Ringo Hoshino. Without a physical body she can't hold her form, so most of the time she lives as a spirit, and only when she transforms does she become one with Ringo Hoshino. She's very weak, very kind, and a bit of a crybaby. But she has lots of friends and can light up everyone around her. She shines brighter than the full moon, brighter even than the sun. She carries a kindness that's hard to put into words. She's usually an elementary schooler, but when she transforms, she grows taller. Her favorite food is cake, and she loves sticking lots and lots of candles in it and sharing it with everyone. Like a shooting star, or like Mercury, she has traveled to all kinds of stars, countries, and towns. To keep the covenant made between God and humanity 2,000 years ago, she holds the key and keeps searching for its answer. Through the story she grows little by little, becoming even kinder than she was yesterday.
