NOT MY VIDEO, I just uploaded it from animevideos.org. Since everyone keeps asking, the anime (in order of appearance and only listed the first time they appear) are Naruto (at the very beginning), Card Captor Sakura, Revolutionary Girl Utena, Read Or Die OVA, Sailor Moon, Plastic Little, Tenchi Muyo, and Steel Angel Kurumi. The song is called Butterfly, by Smile.DK.
