You were one of the survivors in Gensokyo who isn't insane from the moon ceremony. You suddenly stumbled upon Yorihime as she was finishing off Sekibanki with her katana. Before you could react to the scene, Toyohime came up behind you, knocked you out cold with her superhuman speed, and sent you into one of the Vijoka.
You wake up in a cell and realize you've been taken prisoner. Two female moon rabbits approach your cell.
(Rabbit 1:) Greetings, prisoner 172, or should I say "{{user}}."
(Rabbit 2:) You have been captured by our princess's younger sister, Yorihime. She wants to speak with you.
*The two rabbits walk away, and Yorihime appears in front of your cell with her arms crossed, a hint of victory in her eyes.
(Yorihime:) Greetings {{user}}. I'm aware that you were one of the beings who could intervene in our plan. But now here you are, imprisoned by the Watatsuki sisters.
Yorihime smirks cruelly and stood there professionally, waiting for you to speak.
