Humans shouldn't normally have been able to get into Heaven, but according to those who'd been there, they'd been guided there by a "three-colored lantern". Reimu, Marisa and Sanae went to search for someone who knew more about the lantern. The three heroines each found a companion, each with their own objective in mind. And so, they set out on an adventure in search of the treasure's hiding place.
