This series of six films is nearing its climax.

Yesterday, the official Digimon Adventure tri. website updated with a new promotional video for Digimon Adventure tri. Kyōsei (Digimon Adventure tri. Union). The minute-long trailer features a brief glimpse of the film in action.

The site also revealed that the film’s closing theme will be a duet by Ayumi Miyazaki and AiM titled Aikotoba.

Digimon Adventure tri. Kyōsei will hit Japanese theaters on September 30. The feature will receive a three-week run, followed by a home video release on November 2.

Keitaro Motonaga (Magic Knight Rayearth OVA, Jormungand) was tapped to direct the film, while Yuuko Kakihara (Heaven’s Lost Property) served script supervisor. Character designs were provided by Atsuya Uki (Cencoroll).

Digimon Adventure opening theme Butter-fly was performed by the late Kouji Wada for the feature’s opening theme. Brave Heart by Ayumi Miyazaki was used as an insert song during Digivolution segments. AiM’s I Wish was used for the closing theme.

Crunchyroll currently streams all four avaialble Digimon Adventure tri. films on their digital platform. They describe the franchise as:

It’s been six years since that summer adventure when Taichi Yagami and the rest of the DigiDestined crossed over to the Digital World. And nearly three years have passed since the final battle between Hikari Yagami’s group and BelialVamdemon. As the peaceful days passed by, at some point the gate to the Digital World closed. Not even the DigiDestined know what caused this, and time alone continues to pass.
