Made as a revival of the 1967 classic, Ultraseven, Ultraseven X was the 23rd entry in the Ultraman franchise and was also the first Ultra series to be shot in wide screen high-definition format. The show was exclusively for an adult audience and it first aired on October 5, 2007 at 2.15am on CBC and 2.25am on TBS. The series lasted for 12 episodes.
The story begins with the protagonist, Jin, waking up in his apartment with no recollection of his past nor his own identity. He then encounters a mysterious woman named Elea, who warns him of the Aqua Project. Jin soon embarks on a hero’s journey to find out his past and identity, as well as the mysteries behind all the alien attacks around the city. Fighting alongside the amnesiac hero are his fellow DEUS Agents, K and S.
Ultraseven X eventually became a fan favourite among Western Tokusatsu fans (especially those who don’t watch Ultraman) due to its more mature and darker premise, which is almost in similar fashion with one of its predecessors, Ultraman Nexus.
