In the forgotten land of Gensokyo lay many a fantastical creature and personages even more fantastical than any creature – there reside plentiful of vampires, ghosts, tengus, onis, so on and so forth. The land is a refuge for these creatures who are oft forgotten in the 21st century of the Outside World (Earth) and whisked away through a barrier that separates this odd realm from the normal world that exists outside.

An ordinary human named Licorice Meidou finds herself in the grounds of the mansion, with no idea as to where she is or who she is. She ends up being recruited on the whim of the mansion’s mistress, stepping foot into the bizarre land of Gensokyo as she has to contend with whatever fate has in store for her.
