In March 2010, TBS announced they were producing a brand new 7-minute OVA for release only with a repackaged and redesigned boxed set for Season 1. Currently, no plans exist for licensing that special OVA episode. The OVA was the first new anime production since "Fighting Wings" was produced for the 20th anniversary of the manga series. Kodansha released the first OVA for the anime series, bundled with volume 42 of the manga series on February 23, 2011. Volume 42 of the tankouban series was released in two versions, in a standard version without the OVA and a limited edition release contains the OVA. Kodansha produced a second OVA for the anime series. Volume 43 of the tankouban series includes this OVA for the anime series, and it was bundled with the manga release on September 23, 2011.
