Ultraseven X is the 23rd entry in the Tsuburaya Productions’ long-running Ultra Series. It is a revival of the 1967 classic Ultra Seven, and is the first in Tsuburaya Productions’ Ultra hero series to be exclusively for an adult audience and in wide screen high-definition format.
In the final episode (“NEW WORLD”), Ultraseven X is revealed to be the original Ultra Seven, crossed over into a parallel universe in order to save both his world (the “M-78 universe”), and this new one, from the threat of the Shadow Rulers. Ultraseven restored Jin’s life in order to operate in the new world, with Jin serving as his new host. Ultraseven eventually returns to his universe, where Dan Moroboshi (Kohji Moritsugu) is reunited with Anne Yuri (Yuriko Hishimi).
