The DVD contains two different promo videos for the song
"Tokei to Mahou no Biscuit".
The first PV is half CG (computer graphics) and half live video.
It's set up like an old, side scrolling computer game (with low resolution
graphics) with a Shimizu Ai character as the main character.
The second PV is a "normal" PV of the song, even though it does have
a lot of CG backgrounds.
