a dark and cool breeze
the dead return once again
on the demon night

Is "cool" one syllable or two? We'll say one.

You know, actually I have no idea what the story of Halloween is. In school we were taught that it was the one night a year ghosts and ghouls came back and so kids had to dress up to scare them off. Beyond that simple kids story, I have no idea what the history of the day is. Must resist the urge to go to Wikipedia

we have small demon fighters
on Halloween night

(with apologies to Issa)

Halloween has taken Japan by storm the past few years and is now mega popular here, esp with the kids. There are even more kids Halloween events here than back in my hometown in the States.
