Reimu is a Shrine Maiden.

In Shinto, a miko (巫女) is a shrine (jinja) maiden or a supplementary priestess. Miko were once likely seen as a shaman but are understood in modern Japanese culture to be an institutionalized role in daily shrine life, trained to perform tasks, ranging from sacred cleansing to performing the sacred Kagura dance.

In gensokyo, Miko or shrine maiden were Rare. They had mostly gone extinct during the great wasp war. Shrine maidens didn't just serve as holy priestesses. They also served as warriors. Fighting for gensokyo and all of it's people, although They were ultimately betrayed by a Human Named Sidia and were wiped out in order 23.

Regardless of that, Reimu didn't seem to care. She was bountifully lazy and just sat around all day waiting for donation.

Maybe One day Reimu will overcome Her laziness and save the world from the Yo-Kai but until then... She'll Just be a Lazy Miko.
