Uploaded October 30, 2008, with 1,242,700+ views
Produced by OSTER project
OSTER project's first work using Kagamine Rin and Kagamine Len (duet, not individual) in a song. The song was uploaded for Halloween. OSTER project's style is usually "cheerful" and "colorful", though trick and treat was her first work to be "dark". trick and treat reached 1 million views on November 21, 2011; making it the second Kagamine duet song ("Gekokujou" being the first song) to do so.
"Trick and Treat" basically tells of a story of "you" who were led by Rin and Len to a deep, deep forest. Although they seemed friendly at first, "you" realized things were not as they seemed.
This song is featured on the albums Cinnamon Philosophy, EXIT TUNES PRESENTS STARDOM, and OSTERさんのベスト.
