Production
The project inception can be traced back to early spring 2020, when producer Takuya Okamoto received a proposal under the existing series title "The Witch from Mercury," originating from a creative planning unit known as Morion Airlines. This proposal formed the initial conceptual seed for the series' world-building and core themes.[9]
Development continued into 2021, when the series was formally revealed at Sunrise's 2nd "Gundam Conference" (September 15), within the GUNDAM PROJECT, which included initiatives such as G-PARTNER educational outreach. Okamoto revealed that teenage attendees expressed feeling disengaged from the franchise, saying that "Gundam wasn't made for them," which prompted the creative decision to center the story around a school setting in order to better connect with younger fans.[10][11]
The planning team, which included Okamoto, director Hiroshi Kobayashi, co-director Ryō Andō, and writer Ichirō Ōkouchi, crafted a thematic framework focused on corporate competition, futuristic witchcraft, and innovative Gundam technology (the GUND-Format). This concept married elements of Shakespeare's The Tempest and early-modern witch trials, positioning the technology itself as an allegorical "curse."[12] They deliberately structured the story as a dual-audience narrative, appealing to newcomers through a relatable academy backdrop and to longtime fans through morally complex character arcs and signature "dark turning points."[11]
Character visuals originated from mogmo via Morion Airlines' proposal. Animation-adapted character designs were handled by Marie Tagashira (main characters), Shuri Toida, and Hirotoshi Takaya (supporting roles), while mechanical design was split among JNTHED (lead Gundam EXA-Aerial, Lfrith), Kanetake Ebikawa, Ippei Gyōbu, Wataru Inada, Kenji Teraoka, and Takayuki Yanase according to in-universe factions. The creative process emphasized balance, with Kobayashi occasionally generating character visuals himself to ensure narrative cohesion.[13]
This was the first Gundam TV series produced under the newly rebranded Bandai Namco Filmworks (formerly Sunrise since April 2022), marking a new corporate era for the franchise and its media strategy.[14]
