Himitsukessha Taka no Tsume: Teikyou Kakutoku Daisakusen - Sakusen Kaigi

Due to a sponsor issue, Himitsukessha Taka no Tsume Countdown had a Suntory designated advertising campaign that was posted online the same day as it aired on TV Asahi's airing of the main anime (but not for any other TV channel). The ads were also included on the DVD release of the main anime.
