This story is set in the land of Gensokyo,
nestled in Japan and sealed off from the rest of the Outside World.

For Reimu and Marisa,
life in this mystical land had been fairly ordinary.

But when an anomaly occurred that cast them into the Outside World,
the two find themselves wandering an unfamiliar city.

There they meet Sumireko,

a young girl with psychic powers and a fascination with Gensokyo.

Was their meeting a coincidence, or the work of fate?
From that moment, their lives drastically changed...
