The official website for the Fate/Zero television anime series began streaming an advance trailer for the second "Onegai! Einzbern Sōdanshitsu" (Please! Einzbern Consultation Room) bonus extra included with the second Blu-ray Disc Box for the series. Type-Moon's own Kinoko Nasu wrote the extra.

Aniplex of Amerca will release the Japanese box set in North America next Wednesday.
