ultraman nexus (series)
The 18th installment of the long-running Ultra Series.
It's also part of a failed project, known as the "Ultra N Project", alongside with its theatrical movie spin-off, Ultraman the Next.
Unlike its predecessors, this show takes on a much darker, intense tone, as well as being more experimental, than most of the franchise, as a whole.
