Reimu Hakurei is, as the name suggests, the Miko of Hakurei.
She is also a youkai exterminator.
However, she befriends most of the youkai she defeats.
Whenever something strange happens in Gensokyo, she finds out what is happening and puts a stop to it.
Unfortunately, nobody seems to visit the shrine (except the youkai who hang around the shrine often), yet alone worship in it, and as a result, it receives no donations and Reimu has to resort to youkai extermination to earn money.
That's a day in the life of Reimu Hakurei.
