This is just a short music video extra that came bundled with the Blu-Raybox set for the Another series. It is basically just a series of pictures of a chibified Mei Misaki in various settings set to a light ballad. It has very little animation, just some Flash movement for the background and none of the pictures of Mei herself are animated. The uncredited song is pleasant but unremarkable.
This is a peaceful little interlude for fans of the character of Mei. It really adds nothing to the story of the series, nor to our understanding of Mei herself. It has no relation to the horror and psychological mystery of the series, and is not in any way memorable. Recommended only for Mei Misaki admirers and anime completists.
