Night Walker

Background
The song was first uploaded on October 25th 2011; it was Hayakawa-P's first work on using Kagamine Len (append power) in the V3 editor, and it was also one of the first few songs to feature one as well. Hayakawa-P mentioned on his video description how the video contained rather "grotesque" contents as a warning to those who aren't comfortable with such. He also commented how it was more or less a "zombie Halloween" song.

"Night Walker" tells a story of Len waking up, realizing he was a "zombie". He first questioned who he was, he couldn't feel anything, he was confused. Later he regained some memories regarding Rin (she was "blurry" at first) who could be interpreted to be the person who killed Len in the first place. Nonetheless Len spoke of how he loved her and decided to meet Rin again.

A mini trivia to this VOCAROCK song is that the eyes shown on the beginning of the video is Hayakawa-P's eyes himself (and it's also credited to be his eyes).
