yukari's challenge

Reimu, Marisa and Sanae were out hunting for youkai. It was getting late, and the heroines were getting tired. Somehow, they had succeeded to get lost within the outer fields of Gensokyo. One could almost say that they were within the boundary. After a few hours of being hopelessly lost, they suddenly bumped into an old, strong youkai. It was Yukari.

"You three have come deep into my terrain", the reality warper explained, "and I have a challenge for you. Will you succeed, I will guide you out. Will you fail, you will be trapped into my mansion. Will you take it, or are you going to keep on trying to get out by yourselves?"

After a few moments of pondering, the three humans agreed on the challenge. They were required to pick a resource found within Gensokyo and stuff ten of those into their mouths. They could pick any item to their liking, Yukari would retrieve it for them. Reimu was first. She picked money, copper coins. It was going very well for her until at the seventh coin she accidentally swallowed one and had to gag - vomiting the items from her mouth. Marisa was up next. She decided to pick then pearls from a necklace she had - borrowed - from someone. It was an easy task and Marisa was about to win, until she started laughing her ass off, spitting the items from her mouth.

"What the fuck, Marisa", asked Reimu, "you could easily have done that. Why did you fail?"

"It was going very well", the magician answered, "until I started laughing when I saw Sanae gathering
ten men around her."
