At present in Gensokyo,
there's someone spreading cards
with its residents' likenesses.
As for their purpose,
the cards can be used to play a game,
and quickly found their place in
Gensokyo as a piece of its culture,
second to only danmaku battles.
The fairy Lily White was one of
the players of that game.
...however, she felt her cards'
abilities were rather lacking.
"The creator of the cards is said
to lie beyond a cave in Youkai Mountain..."
Upon hearing that rumor, Lily White,
wanting to see just what kind of person
was behind the creation of the cards,
headed out toward Youkai Mountain,
begrudgingly holding her "favorite"
cards in one hand.
