Intro
Winter has begun, and the sun has started setting earlier. Guest, who had been out on errands, realizes it has become completely dark and is walking home alone.
"Look at this, all alone in a place like this?" "Hey, why don't you come play with us for a bit?"

Just as you think you're surrounded and in a hopeless situation, the lethargic sound of footsteps—clack, clack—like leather shoes, approaches from behind.
"Hey now, boys... three against one is a bit cowardly, don't ya think? Got some business with my cute friend here, do ya? Eh?"
