[8][9] To combat the resulting chaos, the Land of Light created the Ultra Medals and Z Risers, but several of these devices were stolen by Celebro, forcing Ultraman Zero and his self-proclaimed disciple Z to chase it to the Earth.

Z carried out his incapacitated master's mission and the Z Riser to recover the stolen Ultra Medals on Earth, where he bonded with STORAGE officer Haruki Natsukawa to combat the space monster Genegarg.

[4][5][6][7] Haruki's mission as a STORAGE member is accompanied by his senior/ace pilot Yoko Nakashima, the young scientist Yuka Ohta, the elderly repairman Kojiro Inaba and his captain Shota Hebikura, whose true identity is Jugglus Juggler from Ultraman Orb.

Meanwhile, the space parasite Celebro took possession of a youth named Shinya Kaburagi to create chaos and experiment with the Ultra's technology to harbor the power of monsters.

He eventually possessed Yoko to hijack Ultroid Zero and transform it into the cyborg monster known as Destrudos to initiate his Civilization Self-Destruction Game on Earth.

Chief producer Tsugumi Kitaura offered Taguchi the role of the main director in August 2019 and the latter requested the inclusion of Kota Fukihara, as well as the pair to rewrite the original draft to their own preference.

[11] In previous entries of the Ultra Series, the defense team concept was dropped out so as to save the production cost, but Taguchi proposed the inclusion of giant robots as alternatives to combat vehicles.

The first to be created was King Joe STORAGE Custom, but Sevenger was introduced earlier in the series to garner attention from fans for its cuter appeal.

[4][5][6][7] As the first trailer of the series was released on April 16, 2020, the official website of Tsuburaya Productions quickly announced Kiyotaka Taguchi as its main director, Tatsuomi Hamada's return as the show's supporting cast and finally Masaaki Endoh and Nami Tamaki singing the opening and ending themes respectively.

All mini episodes are directed and written by Kiyotaka Taguchi and Junichiro Ashiki respectively, while Kohshu Hirano, Rima Matsuda, Hikari Kuroki and Takaya Aoyagi provided the background voices.

[24] Life's Decision Height: The Story of STORAGE's Foundation (擲命のデシジョン・ハイト ―ストレイジ創設物語―, Tekimei no Deshijon Haito Sutoreiji Sōsetsu Monogatari) is a two-part novel spin-off released on Tsuburaya Imagination.

It is written by Takao Nakano and supervised by Kiyotaka Taguchi and Tsuburaya Productions, and serves as a prequel to the television series from Jugglus Juggler's perspective.

[51][52] In addition to television airing, episodes of Ultraman Z were rebroadcast on YouTube for worldwide audience to watch, at Taguchi's suggestion, which also included English subtitles.
