Bandai Visual revealed that a new OVA in the Agent Aika franchise will hit Japan on August 25. The OVA, titled AIKa Zero, will feature character designs by Noriyasu Yamauchi (Agent Aika, Najica Blitz Tactics). Kenichi Kanemaki (Galaxy Angel, Ai Yori Aoshi) will write the series' script, while the story is a product of Studio Fantasia and Bandai Visual's original concepts. Ami Koshimizu (Kujibiki Unbalance, Spice and Wolf) will reprise her role as Aika Sumeragi. Koshimizu will also perform the opening song.

First-editions of the Blu-ray release will include a special "H pinup" illustration by Yamauchi, a bonus booklet, audio commentary, and a "picture drama" video extra.
