Vertex Force Is Betting Gundam's Mecha Designers Can Make You Care About a Family Secret

Original mecha anime are a hard sell in a season dominated by sequels and manga adaptations, because there is no built-in audience to inherit and no existing fandom to carry the marketing. Vertex Force, which premiered October 3, 2026 from Aniplex, is making its case the old-fashioned way: hire a director with a specific sensibility, bring in mechanical designers with recent pedigree everyone already respects, and build the story around people first.

Here is what is actually going on with it, for anyone who saw the key visual and wants the real picture before committing a season to it.

The family at the center of it

Vertex Force opens on the Todo family living an ordinary life. Akira, the younger brother, has no inherited power of his own. His older sister Haruka does, a hidden ability called Engine that the family has apparently been keeping quiet. Their mother runs a cafe. It is a deliberately grounded setup for a mecha show, closer to a slice-of-life opening than a battlefield, and that contrast is clearly intentional: the series needs mysterious enemies to surface in Okinawa before the actual stakes of Haruka's power become unavoidable.

Putting the sibling relationship ahead of the hardware is a specific structural choice. A lot of mecha shows front-load their world-building and let characters catch up to the plot. Starting instead on a family with a secret they have not had to use yet means the first real battle should land as a disruption to an established normal, rather than as the thing the show was always obviously building toward from frame one.

Who is actually flying these machines

Kaede Hondo voices Haruka Todo, with Makoto Koichi as her brother Akira. The supporting cast adds real weight: Ami Koshimizu as Eleanor Northbrook, Megumi Han as Lara Zudenstein, and Rie Takahashi as Youko Nishina. That is a deep bench of recognizable voices for an original property with no built-in audience, and casting choices like that are usually a studio signaling confidence in a project rather than treating it as a minor seasonal filler slot.

The mecha pedigree is the part worth actually caring about

Kazuhiro Takamura directs, and his résumé, Strike Witches and Vividred Operation, tells you roughly what sensibility he brings: a comfort with blending cute-girl character writing and mechanical spectacle without treating either half as the lesser priority. He also handles character design and shares series composition duties with Masashi Suzuki, with Goro Kuji, whose credits include Chained Soldier and Peleliu: Guernica of Paradise, assisting as director.

The mechanical design credits are the detail that should actually get mecha fans paying attention. Kanetake Ebikawa, credited as engine designer, and JNTHED, handling what the production calls ENIA design, both worked on Mobile Suit Gundam: The Witch From Mercury, one of the more visually distinctive Gundam entries of the last several years. Bringing that specific design language into an original property, rather than a licensed Gundam project, gives the studio a chance to build mecha silhouettes without the weight of forty years of franchise continuity shaping every decision. SMDE, short for Shogakukan Music & Digital Entertainment, handles the animation itself.

Nobuaki Nobusawa, who scored Clevatess and Astra Lost in Space, composes the music, and ClariS performs the opening theme, "Synchro Blue."

Where and when to actually watch it

Vertex Force broadcasts in Japan at 11:30 p.m. on Tokyo MX, BS11, Gunma TV, and Tochigi TV, with simultaneous streaming on U-NEXT and other Japanese services. Internationally, Crunchyroll holds the license, with Medialink handling distribution across Southeast Asia. If you are tracking this one for a simulcast, Crunchyroll's fall lineup is the place to check for your region's exact schedule, since broadcast-to-stream timing can shift week to week this early in a season.

Is this worth adding to a fall watchlist

If you want a mecha series that is trying to earn its action through character relationships instead of defaulting straight to spectacle, Vertex Force has assembled a staff that at least makes that approach plausible. Takamura's track record suggests he will not let the Todo family's dynamic get steamrolled by the hardware once Haruka's Engine power actually gets used in earnest, and designers coming straight off The Witch From Mercury are a reliable sign the machines themselves will look distinct rather than generic.

The honest caveat is that an original mecha anime lives or dies on execution more than any sequel does, because there is no existing fanbase willing to forgive a rough start. The premiere has aired. Whether the Todo family's secret actually pays off across a full season is the thing worth checking back in on once more episodes land.
