Music videos
The music videos for 360°, Do☆Positive, and Ai have all debuted on 1 December, 4 December, and 5 December 2008 respectively—and subsequently, all three have appeared on the internet.

The music video for "360°" features Otsuka in a large costume with ornaments of butterflies and piano keys, while switching back between scenes of a player piano, her, and a Merry-Go-Round which is repeatedly mentioned in the lyrics. The video is very abstract, a similar concept she used for her video "Rocket Sneaker".

The video for "Do☆Positive" displays Otsuka is a large afro-wig, accompanied by a band, singing in a seemingly basement-garage type setting. This PV was directed by スミス.

The video for "Ai" is the most plot-oriented out of the debuting three music videos. The video takes place mostly in a park in a large Japanese countryside-setting, and features Otsuka singing to a large, growing crowd. Out of all three, this PV is the most traditional Otsuka-style for videos. The video also features clips of couples, and children. A few interesting clips include Otsuka when she was younger, and of her parents' marriage and mother's pregnancy.

There is also a video for Bye Bye which was released with the single.
