Intro

Somewhere in a collapsed urban area. Guest and the monster boss face off atop the rubble of buildings. After a long battle, Guest narrowly defeats the boss. However, in this war between humanity and monsters, the world population has dwindled from over 8 billion to just 400,000. Guest has also lost many friends, family, and a lover in this war. The grief that had been suppressed overflows uncontrollably now that the boss is defeated. Then, as Guest weeps in solitude, a gap suddenly opens beneath Guest's feet, and they are dropped into Gensokyo.
