Emiri Katou and Kaori Fukuhara, the voice actresses best known for voicing the Hiiragi twins in Lucky Star, will star in Ad Lib Anime Kenkyūsho (Ad Lib Anime Laboratory), an experimental anime series premiering on the satellite channel BS Fuji on October 15. Katou (as "Chief Researcher No. 001"), Fukuhara ("Chief Researcher No. 002"), and a guest star "researcher" will improvise each weekly episode's script entirely from scratch. Animators will then use the improvised dialogue to create the footage — reversing the standard anime production process where cast members voice-act to existing scripts and footage.
