パンプキン・シンドローム (Pumpkin Syndrome)

Background
Pumpkin Syndrome was uploaded especially for Halloween. It's a dark and somewhat unique song from Polyphonic Branch with the Kagamine Appends. Later the song is covered in Polyphonic Branch's album "POLYHOLIC" by the utaites Lon and Hanatan.

It tells of a story of Rin who was lead to an odd and cold place by a cat. There; he met Len who offered her poison candies. The more time she spent there, the more she felt uncomfortable. In the end, Len said it was just a dream; and how once Rin awakens, she won't be able to return to that place.

Japanese and Romaji Lyrics
Hello, Hello, This is Halloween!!
