圓谷製作
is a Japanese television miniseries produced by Tsuburaya Productions, aired during the ending segment of the New Ultraman Retsuden programming block on TV Tokyo. The official YouTube Channel of Tsuburaya Productions aired this miniseries legally with each episode that was uploaded to the Tsuburaya Productions YouTube Channel being deleted a week after their initial upload. It was available in regions that are currently region locked such as the United States. In promotion to the 2-part episodes 13 and 14 of "Ultraman X", which features the crossover with the cast of "Ultraman Ginga S", the Tsuburaya YouTube channel decided to re-aired a full episode instead of miniseries cuts, retaining the original subtitle. However, this video (like the first miniseries cut) was limited until it would be locked in October 24, 2015.
