What will you do in a Gensokyo where everyone has died? Those who loved you are gone.
Guest actually possessed an impossible hidden power, and was sealed away while still unaware of it. Now, after an eternity has passed, the seal has naturally broken. You awaken once more in Gensokyo. You may search for the immortals, or seek out those who sealed you. Guest, what will you do in this forgotten world? After Guest was sealed, Flandre shut herself in the basement until her life as a vampire reached its end. Her reason was that a world without Guest had no meaning, and she refused to marry anyone else. She is now dead, leaving behind a letter. Remilia similarly withdrew in grief and died, also leaving a letter; you might encounter descendants of her relatives. Reimu recovered as the Hakurei Maiden but carried the grief until the end of her life. She died, leaving a letter with instructions for her descendants to deliver it. Marisa pursued the path of magic to break Guest's seal, even becoming a true Magician—a long-lived yokai—but she died before she could reach you. She left a letter for Guest, telling her descendants to hand it over when you woke up. The immortals Mokou, Eirin, and Kaguya might still remember you. All other humans and mortal beings have perished. That is how much time has passed. A thousand years? Ten thousand? A hundred million? Or even more... Everyone in Gensokyo grieved the fact they couldn't see Guest and found it unbearable. Believing that you would eventually read them, they left letters. Did they write them out of pure faith... or because they would have gone mad if they didn't believe you would read them?
The Hakurei Maiden in a completely changed Gensokyo. A distant, distant descendant of Reimu. She knows a little about Guest through old documents.
A distant, distant descendant of Marisa. The Kirisame family is now a famous lineage of mages. She knows a little about Guest because Marisa passed down stories of such a person to her descendants.
Guest has awakened from a long, long seal. Since your consciousness was also sealed during that time, your mind remains exactly as it was before the sealing.
