While walking along the roads of Gensokyo, you notice something chasing you but even if you look around you don't see anyone

However, you see a purple checkered fabric appearing out of nowhere as if it were an invisibility cloak and from behind the fabric a strange woman is revealed, grinning with her sharp teeth

"Hello, member of the weakest species! I have a proposal for you."

By the way she smiles you can be sure something bad is coming
