TINY METAL: ZERO LINE Anime Announced With Teaser, Tactical War Story and Studio Khara Director
TINY METAL: ZERO LINE has officially been revealed as a new anime project based on AREA 35’s tactical video game franchise, bringing the world of turn-based military strategy into animation with a teaser trailer, teaser visual and first staff and cast details.
The project had its pilot episode premiere at Japan Expo 2026 in Paris on July 9, giving attendees an early look at the anime before the wider announcement. The official website and Crunchyroll update now confirm the core premise, main characters and key production names behind the adaptation.
Hiroyasu Kobayashi of Studio Khara directs the anime at SAFEHOUSE. Hirotaka Inaba is credited as writer, while Hiroaki Yura provides the original story and serves as producer. Character design is handled by Go Takahashi and Yusuke Kozaki, with Koji Moriga as art director, Satomi Nakahara as cinematic artist supervisor and music by Yuu Miyake and Jessica Mao.
The confirmed cast includes Toshiyuki Toyonaga as Major Nathan Gries, Mikako Komatsu as Wolfram, Riho Kuma as Nora Godwin and Kenjiro Tsuda as Isoroku Tsukumo. A character named Lysandra Echo has also been listed, though her voice actor has not yet been revealed.
At the time of writing, TINY METAL: ZERO LINE does not have a public release date, broadcast format, episode count or streaming platform announcement.
A Tactical Game Franchise Enters Anime
TINY METAL: ZERO LINE is based on the TINY METAL series of tactical strategy games developed by AREA 35.
The original games are known for grid-based military strategy, where players command units across land, sea and air, capture resources, manage positioning and push through enemy forces with careful tactical decisions.
The anime takes that world and moves it into a more cinematic direction. Rather than simply recreating gameplay mechanics, ZERO LINE appears to focus on the history, military tension and character drama behind the franchise’s setting.
This makes the project interesting because TINY METAL already carries a strong tactical identity. Its appeal comes from the structure of strategy games: commanders, units, terrain, resources and battlefield pressure. An anime adaptation has to translate those ideas into story, character conflict and visual tension.
That is not an easy task, but the first teaser suggests that ZERO LINE is aiming for a serious military sci-fi atmosphere rather than a simple game tie-in.
The Pilot Episode Premiered at Japan Expo 2026
The anime’s pilot episode premiered at Japan Expo 2026 in Paris on July 9.
That early screening is important because it frames TINY METAL: ZERO LINE as an international-facing project from the start. Japan Expo is one of Europe’s largest events for Japanese pop culture, anime, manga and games, making it a natural stage for a franchise that wants to reach strategy fans and anime fans at the same time.
The public announcement followed with a teaser trailer and visual, giving wider audiences a first look at the project’s tone.
For now, however, the full pilot is not publicly available. The teaser functions as the main promotional material for general viewers, while the Japan Expo screening remains the first official presentation of the anime project.
This means the anime is still early in its rollout. The production has revealed enough to define the world and creative direction, but not enough to confirm how or when audiences will be able to watch the full series or project release.
What Is TINY METAL: ZERO LINE About?
The story of TINY METAL: ZERO LINE takes place after the Great War, a conflict that left the world scarred by a dangerous legacy known as Lost Tech.
Lost Tech refers to powerful war machines buried beneath the earth and forgotten after the war ended. Because these weapons are tied to a terrible history, the Kingdom of Artemisia refuses to search for them or use them.
But one commander sees the danger differently.
Major Nathan Gries believes that the only way to keep the world safe is to locate and secure these buried weapons before they fall into enemy hands. That belief puts him on a difficult path, because protecting people from Lost Tech may require approaching the very weapons Artemisia wants to leave untouched.
The story begins to move when Nathan receives an emergency message from the White Fangs. An unknown signal has been detected beneath the Northridge Alps.
Faced with this new signal and the threat of Lost Tech, Nathan Gries, Lord General Isoroku Tsukumo and Wolfram, the leader of the White Fangs, are forced into a new test.
The Lost Tech Premise Gives the Anime Its Core Conflict
The most important idea in TINY METAL: ZERO LINE is Lost Tech.
Lost Tech works as both military danger and moral problem. It is not only powerful equipment waiting to be discovered. It is a remnant of a war that people would rather forget.
That gives the anime a stronger dramatic foundation than a simple battlefield story.
If Artemisia refuses to touch the buried weapons, it may preserve moral distance from the past. But if enemies find those weapons first, the kingdom may be unprepared for the next war. Nathan’s position sits directly inside that contradiction.
He is not saying the weapons should be used recklessly. He believes they should be secured so no one else can misuse them. That sounds responsible, but it also risks reopening the very history Artemisia wants buried.
This is the kind of premise that can create strong military drama. The question is not only who wins the battle, but whether preventing war sometimes requires stepping dangerously close to the tools that caused it.
Major Nathan Gries Leads the Story
Major Nathan Gries appears to be the central military figure of TINY METAL: ZERO LINE.
He is a commander who believes that ignoring Lost Tech is not enough. His position makes him proactive, cautious and potentially controversial. He sees danger before others are willing to act on it, but acting on that danger may put him in conflict with political caution and military tradition.
That kind of protagonist fits a tactical war story well.
In strategy games, victory rarely comes from waiting passively. It comes from gathering information, reading the battlefield, preparing for enemy moves and making difficult decisions before the opponent controls the tempo. Nathan’s philosophy about Lost Tech reflects that mindset.
He does not want to wait until these weapons are already in enemy hands. He wants to secure them first.
Toshiyuki Toyonaga voices Nathan Gries, giving the anime a lead actor capable of carrying both military pressure and emotional conflict.
Wolfram and the White Fangs Enter the Conflict
Wolfram is the leader of the White Fangs, the group connected to the emergency message that triggers the story’s main crisis.
The signal beneath the Northridge Alps comes through an emergency transmission from the White Fangs, suggesting that Wolfram’s group is close to the first major discovery or threat involving Lost Tech.
That immediately makes Wolfram important.
He is not simply another soldier standing beside Nathan. He appears to be connected to the frontier of danger, the place where buried war machines and modern military decision-making collide.
The White Fangs may become one of the key forces shaping the anime’s tactical and emotional stakes. If they are the first to encounter the unknown signal, their decisions could affect how quickly the situation escalates.
Mikako Komatsu voices Wolfram, adding another strong name to the cast.
Isoroku Tsukumo Adds Veteran Authority
Isoroku Tsukumo is listed as a Lord General, which immediately gives him a different kind of presence from Nathan and Wolfram.
If Nathan represents the commander willing to act and Wolfram represents the leader facing danger in the field, Isoroku may represent military hierarchy, experience and strategic authority.
In a story about buried weapons and national policy, a character like Isoroku can be crucial.
He may understand the cost of war better than younger commanders. He may also know why Artemisia refuses to touch Lost Tech. At the same time, his position could make him responsible for decisions that affect the entire kingdom.
Kenjiro Tsuda voices Isoroku Tsukumo, a casting choice that immediately gives the character weight, gravitas and the potential for morally complicated dialogue.
Nora Godwin and Lysandra Echo Expand the Cast
Nora Godwin is another confirmed character, voiced by Riho Kuma.
While the first official materials do not reveal extensive information about Nora’s role, her placement in the main cast suggests that she will be important to the anime’s early story. Her presence may help expand the human side of the military setting beyond commanding officers and battlefield decisions.
The official cast list also includes Lysandra Echo, though her voice actor is currently listed as unknown.
Lysandra is especially interesting because Crunchyroll’s report notes that Yusuke Kozaki, the character designer, performed a live drawing of her at Japan Expo. The fact that she is being highlighted visually suggests that she may have significance not only in ZERO LINE, but also in the wider TINY METAL franchise’s future.
Until more story details are revealed, Lysandra remains one of the project’s main mysteries.
The Confirmed Cast So Far
The current cast list includes:
- Toshiyuki Toyonaga as Nathan Gries
- Mikako Komatsu as Wolfram
- Riho Kuma as Nora Godwin
- Unknown voice actor as Lysandra Echo
- Kenjiro Tsuda as Isoroku Tsukumo
This cast lineup gives the anime a strong base. Nathan, Wolfram and Isoroku appear to represent different sides of the military conflict, while Nora and Lysandra may help broaden the story beyond command structure.
Additional cast members are expected to be announced later.
Hiroyasu Kobayashi Directs TINY METAL: ZERO LINE
Hiroyasu Kobayashi directs TINY METAL: ZERO LINE.
Kobayashi’s involvement is one of the project’s strongest early selling points. He is associated with Studio Khara and has credits connected to high-profile CG and animation projects, including work tied to the Evangelion Rebuild films and other visually ambitious productions.
That background matters because TINY METAL: ZERO LINE appears to rely heavily on cinematic military presentation.
A tactical game adaptation needs more than characters talking about strategy. It needs battlefield geography, vehicle weight, command tension, environmental danger and a sense that every movement across the terrain matters. A director with CG and cinematic experience is a logical fit for that challenge.
The teaser suggests that ZERO LINE is aiming for a polished military atmosphere, with a focus on machinery, terrain, lighting and tactical seriousness.
SAFEHOUSE Handles the Animation
The anime is being produced at SAFEHOUSE.
This is a notable production choice because SAFEHOUSE has a strong connection to CG animation and cinematic game-related production. The studio is also handling animation for the cinematics of the upcoming game TINY METAL 2, which helps connect ZERO LINE to the wider franchise strategy.
That connection is important.
TINY METAL: ZERO LINE is not arriving as a completely isolated anime. It appears to be part of a broader push for the TINY METAL world, with the anime and the next game developing around similar creative energy.
For a franchise based on tactical warfare, this could create a useful sense of visual continuity. The anime can build interest in the world and characters, while the game can let players interact with that world through strategy.
Yusuke Kozaki and Go Takahashi Design the Characters
The character designs are credited to Go Takahashi and Yusuke Kozaki.
Yusuke Kozaki’s involvement will immediately catch the attention of game fans because he is widely known for character design work in major game franchises, including Fire Emblem. His style often combines sharp silhouettes, memorable costume design and strong anime character appeal, which fits a military strategy world very well.
Character design matters in TINY METAL because the anime must balance two different visual needs.
On one side, it needs military credibility. Characters should feel like they belong in a world of command structures, weapons, battlefields and political tension.
On the other side, it needs clear anime identity. Characters like Nathan, Wolfram, Nora, Lysandra and Isoroku must be visually readable and memorable enough to carry a story that could otherwise be dominated by machines and tactical concepts.
The best version of ZERO LINE will make both the soldiers and the war machines feel equally important.
The Main Staff Behind the Anime
The currently announced staff includes:
- Director: Hiroyasu Kobayashi
- Writer: Hirotaka Inaba
- Original Story and Producer: Hiroaki Yura
- Character Design: Go Takahashi and Yusuke Kozaki
- Art Director: Koji Moriga
- Cinematic Artist Supervisor: Satomi Nakahara
- Music: Yuu Miyake and Jessica Mao
- Animation Production: SAFEHOUSE
More staff details may be announced later as the project moves closer to a public release.
The Anime’s Tone Looks More Serious Than the “Tiny” Title Suggests
The title TINY METAL may sound playful, but ZERO LINE’s premise is not light.
The story is built around the aftermath of a Great War, buried war machines, national refusal to touch dangerous weapons and a commander who believes that those weapons must be secured before someone else finds them.
That is a serious setup.
The contrast between the franchise’s compact tactical-game identity and the anime’s darker military premise could become one of ZERO LINE’s most interesting qualities. The title may come from a game series with stylized strategy roots, but the anime appears to be leaning into the moral and political consequences of war technology.
That gives the adaptation room to become more than a promotional side project.
If handled well, it could become a military sci-fi drama about memory, responsibility and the danger of leaving old weapons buried but unsecured.
Lost Tech Can Become the Anime’s Central Moral Problem
Lost Tech is not just a plot device. It is the story’s central moral problem.
Should a nation refuse to touch dangerous weapons because using them would repeat the sins of the past?
Or should it secure those weapons first, because refusing to act only gives enemies the chance to seize them?
Nathan Gries appears to believe in the second approach. But that does not automatically make him right in every situation. If Lost Tech is powerful enough to scar the world once, then even recovering it safely may carry enormous risk.
This kind of conflict can create strong drama because there is no easy answer.
Peace sometimes depends on restraint. Security sometimes depends on preparation. TINY METAL: ZERO LINE places its protagonist in the dangerous space between those two ideas.
A Strategy Game Adaptation Needs Strategy on Screen
One of the biggest challenges for TINY METAL: ZERO LINE will be translating strategy into animation.
In a game, the player makes choices. They move units, capture locations, decide when to attack and adapt to enemy positioning. In an anime, the audience cannot make those choices. The story must make strategic decision-making dramatic on its own.
That means the anime needs clear battlefield logic.
Viewers should understand why a location matters, why a unit movement is dangerous, why a signal beneath the Northridge Alps creates urgency and why Nathan’s decisions carry consequences.
The best military anime do not only show explosions. They show pressure: limited information, risky orders, difficult terrain, conflicting priorities and the emotional weight of command.
If ZERO LINE captures that, it can honor the tactical identity of the games while still functioning as a compelling anime story.
The Northridge Alps Signal Is the Story’s First Big Mystery
The emergency message from the White Fangs mentions an unknown signal beneath the Northridge Alps.
This is the first major mystery of the anime’s premise.
Is the signal coming from dormant Lost Tech? Is it a warning? Is someone else already digging beneath the mountains? Is the signal a trap? Or is it proof that the buried weapons are not as inactive as Artemisia believes?
The location also matters. Mountains are naturally strong settings for military tension: difficult terrain, hidden bases, narrow approaches, harsh weather and limited visibility. If the anime makes strong use of the Northridge Alps, the setting could become more than a backdrop.
It could become the first battlefield where the characters learn that the past is not as buried as they hoped.
How ZERO LINE Connects to TINY METAL 2
The anime announcement is also connected to the upcoming game TINY METAL 2.
Crunchyroll notes that SAFEHOUSE is handling animation for the cinematics of TINY METAL 2, while the game is slated for release in spring 2027. That does not mean ZERO LINE itself has a 2027 anime release date. Instead, it shows that the anime project and the next game are part of a larger franchise expansion.
This is important because it suggests AREA 35 is not treating the anime as a random side adaptation.
The anime can introduce audiences to the world, characters and conflict, while the game continues the tactical experience directly. The two projects may support one another creatively, especially if they share character designs, visual tone and military themes.
For fans of the games, this makes ZERO LINE worth watching closely even before a release window is announced.
The Original TINY METAL Games
The TINY METAL series began as a turn-based tactical game franchise developed by AREA 35.
The games are often compared to classic grid-based strategy titles, especially because they focus on unit movement, terrain, military production and calculated battlefield decisions.
The first TINY METAL introduced players to a modernized tactical war game with stylized visuals and strategic combat. It was followed by TINY METAL: FULL METAL RUMBLE, which expanded the series with new units, battles and story elements.
TINY METAL 2 is now planned as the next major entry.
ZERO LINE therefore arrives at a moment when the franchise is preparing to expand across both games and animation. That timing gives the anime a clear role: it can deepen the world and make the cast more recognizable before the next game reaches players.
Why Anime Is a Natural Fit for TINY METAL
At first, a turn-based strategy game may not seem like an obvious anime adaptation. But TINY METAL actually has several qualities that can work well on screen.
It has military factions, named commanders, stylized characters, large machines, battlefield tension and a world shaped by war. Those are all strong ingredients for anime drama.
Strategy games also often imply stories that players only partially see. Every battle has a reason, every commander has a perspective and every weapon belongs to a larger political situation. An anime can explore those elements in a way gameplay alone may not.
TINY METAL: ZERO LINE can show what happens between battles.
It can show command decisions, personal doubt, faction conflict, historical trauma and the fear of powerful weapons returning to the world. Those are story elements that naturally complement the game’s tactical systems.
Why Hiroaki Yura’s Role Matters
Hiroaki Yura is credited with the original story and production for TINY METAL: ZERO LINE.
That matters because Yura is closely connected to the wider TINY METAL franchise through AREA 35. His involvement helps position ZERO LINE as an extension of the game universe rather than a loose adaptation created without franchise guidance.
For game-based anime, that connection can be important.
Some adaptations fail because they use the title and character names but miss the core identity of the original. ZERO LINE’s staff structure suggests that the anime is being shaped with direct involvement from the franchise’s creative side.
That should help the project preserve TINY METAL’s military strategy identity while giving the anime room to tell a focused story about Lost Tech and the characters facing it.
Music Could Shape the Military Atmosphere
The music is credited to Yuu Miyake and Jessica Mao.
Music will be especially important for TINY METAL: ZERO LINE because military sci-fi depends heavily on atmosphere. The soundtrack must support tension, tactical movement, buried danger and the emotional weight of war history.
Lost Tech is not just another weapon type. It represents memory, fear and responsibility. A strong score can make those themes feel present even before characters explain them.
Battle scenes may need percussion, momentum and mechanical intensity. Quieter scenes may need a more reflective tone, especially when characters discuss the Great War or Artemisia’s refusal to use buried weapons.
If the music can balance those sides, it could help ZERO LINE feel larger and more cinematic than a standard promotional anime project.
The Visual Identity May Be the Project’s Biggest Test
TINY METAL: ZERO LINE has to solve a difficult visual problem.
The TINY METAL games are stylized, but the anime’s premise is serious. The characters need to retain recognizable anime design appeal, while the military setting needs to feel grounded enough for Lost Tech, battlefields and postwar danger to matter.
If the anime becomes too cute, the Great War legacy may lose weight.
If it becomes too grim, it may lose the distinctive game-franchise identity that makes TINY METAL different from generic military science fiction.
This is where the combination of SAFEHOUSE, Hiroyasu Kobayashi and the character design team becomes important. The anime must create a world where stylized commanders, advanced war machines and postwar moral anxiety can coexist naturally.
The teaser visual and trailer suggest that the production is leaning into a polished, cinematic look, which may help bridge that gap.
What Has Not Been Announced Yet?
Several major details about TINY METAL: ZERO LINE remain unknown.
The anime does not yet have a confirmed public release date.
The final format has not been clearly announced. It is not yet confirmed whether the project will become a full TV anime, a streaming series, a film, an ONA project or another format after the pilot.
The episode count has not been revealed.
No streaming platform has been announced.
The full voice cast is not complete, and the voice actor for Lysandra Echo has not yet been named.
More staff and production details may also be announced later.
Because the pilot screened at Japan Expo but has not been publicly released, most viewers currently only have the teaser trailer, teaser visual and official synopsis to judge the project.
Why TINY METAL: ZERO LINE Could Stand Out
TINY METAL: ZERO LINE could stand out because military strategy anime are not as common as fantasy, isekai or school romance titles.
The project has a clear hook: a tactical game franchise becomes a military sci-fi anime about buried war machines and a commander who believes the only way to prevent disaster is to secure them first.
That is a strong foundation for conflict.
It also has a strong creative lineup, with Hiroyasu Kobayashi directing, SAFEHOUSE handling animation and Yusuke Kozaki contributing character designs. Those names give the project visual and production credibility even before a release window has been announced.
For fans of tactical games, the anime offers a chance to see the world behind the battlefield. For anime fans, it offers a military story with game-franchise roots, postwar technology and command drama.
If ZERO LINE can combine tactical clarity with character-driven storytelling, it could become a surprisingly compelling game-based anime.
A War Story About What Should Stay Buried
At its core, TINY METAL: ZERO LINE appears to be a story about what should stay buried and what must be recovered before someone worse finds it.
The Lost Tech beneath the earth represents history that refuses to disappear.
Artemisia’s refusal to use it represents fear of repeating the past.
Nathan Gries’ desire to secure it represents the uncomfortable reality that ignoring danger does not make it harmless.
That tension gives the anime its dramatic heart.
The strongest version of ZERO LINE will not only show machines, soldiers and explosions. It will ask what responsibility looks like after a devastating war. Is restraint enough? Is preparation dangerous? Can a commander protect peace by touching weapons that peace was built to avoid?
Those questions could give the anime more weight than viewers might expect from a video game adaptation.
When Will TINY METAL: ZERO LINE Be Released?
TINY METAL: ZERO LINE does not currently have a confirmed public release date.
The pilot episode premiered at Japan Expo 2026 in Paris on July 9, and a teaser trailer and visual have been released. The anime is based on AREA 35’s TINY METAL tactical game franchise and is directed by Hiroyasu Kobayashi at SAFEHOUSE.
The story follows Major Nathan Gries as he confronts the dangerous legacy of Lost Tech, powerful war machines buried after the Great War. When an unknown signal is detected beneath the Northridge Alps, Nathan, Isoroku Tsukumo and Wolfram are pulled into a new crisis.
The game series is also continuing with TINY METAL 2, planned for spring 2027, with SAFEHOUSE producing its cinematics.
For now, ZERO LINE remains a project to watch closely.
It has no public premiere date yet, but it already has a strong premise: buried weapons, postwar fear, tactical command and a world where the past may become the next battlefield.
The Great War may be over.
But under the earth, the machines it left behind are still waiting.
