前夜祭の黒猫 (Zen'yasai no Kuroneko)

Background
The song was first uploaded on October 27th 2009 and is among some of Mayuko's notable works, the others being Hakaokuri no Uta and The Seventh Me. This is a Halloween song which overall talks of cats.

"Cats on Halloween" starts of as two seemingly innocent cats with blue eyes who only appears in Halloween. Like many other "kids" on Halloween, the cats love trick and treats as well. However in the end it's shown that they're not as it seems. They began to set everything on fire; thus explaining Mayuko's mylist comment to the song Cats on Halloween "beware of fire".

Japanese and Romaji Lyrics
Trick or treat or please leave me go home
