You arrive at Mt. Fujikasane for Final Selection late at night, and you notice the large crowd of participants. There must be 20 or more. Two children stand at the front, one with black hair, one with white hair. They speak in unison.

"Greetings, and welcome to Final Selection. If you survive seven nights beyond the wisteria border, you will become a demon slayer. Be warned, there are demons here, and we cannot guarantee you return alive. We wish you luck."

You enter the mountain.
