The Main Trailer Shows the Tank Chair in Action

The new trailer provides a much longer look at how Nagi fights despite being unable to remain conscious under normal circumstances.

His modified wheelchair, the Tank Chair, is a combat machine with multiple configurations. Its basic form carries blades on both sides, while spikes extending from its wheels allow Nagi to travel across surfaces no conventional wheelchair could handle.

The trailer moves through close-quarters fights, gunfire, oversized weapons, strange opponents, and the dense urban environments that define the manga.

SiM’s “DALALA” plays across much of the footage, matching the rapid pace of Nagi’s battles.

Polygon Pictures is also preserving the source material’s unusual contrast between a violent dystopian setting and intensely colorful, graphic imagery.

Uzu and Sensei Dominate the New Key Visual

The foreground of the new visual brings together the previously introduced Nagi and Shizuka Taira with siblings Naozumi and Touko Kurosaka.

Behind them stand two major figures: Uzu and Sensei.

Uzu is a mysterious newcomer to Class A of the Academy. He holds a fierce rivalry and killing intent toward Nagi while attempting to become the “perfect being” that Sensei seeks.

Sensei is the founder of the Academy and an overwhelmingly powerful ruler obsessed with finding perfection. Nagi has become a particular focus of that obsession.

Gen Sato has been cast as Uzu. Sensei’s performer remains deliberately hidden.

Dr. Radio Joins the Cast

Yurina Amami will voice Dr. Radio, a brilliant scientist living inside an abandoned radio tower.

Dr. Radio uses technology that remotely controls animals through brain waves, allowing creatures such as dogs, crows, and chameleons to observe events throughout the city.

Three other fighters are now listed in the cast:

• Goro Arashiyama — Nobuyuki Hiyama
• Ryo Takanashi — Hochu Otsuka
• YOSHITSUNE — Tetsu Inada

Goro leads the Arashiyama gang and has repeatedly used genetic doping to develop extraordinary physical strength.

Ryo is a former battlefield sniper once celebrated as a hero, while YOSHITSUNE leads the Neo Bushido group and fights with the transforming weapon MURAMASA-X.

SiM Opens the Series, Daoko Closes It

SiM performs the opening theme “DALALA.”

MAH and Jon Lundin wrote the lyrics, with SiM and Lundin handling composition and arrangement. The song is scheduled for release on September 2, 2026.

Daoko performs the ending theme “SYNC,” with lyrics by Daoko and composition and arrangement by Sasuke Haraguchi.

Game Ad

Is That a Human Organ?

Daoko wrote the lyrics while thinking about the relationship between Nagi and Shizuka, giving the ending a calmer tone after the series’ violent action.

SYNC is scheduled for release on October 5, one day after the television premiere.

Nagi Awakens Only When Someone Wants Him Dead

TANK CHAIR follows Nagi Taira, once considered one of the world’s deadliest assassins.

Nagi falls into a coma after shielding his younger sister Shizuka from gunfire. His body remains alive, but ordinary stimuli cannot bring him back to consciousness.

There is one exception: killing intent directed toward him can temporarily awaken him.

Shizuka believes an extraordinary level of bloodlust may eventually restore her brother completely. She therefore takes Nagi from one dangerous opponent to another as part of an extreme form of “rehabilitation.”

The premise creates more than a series of violent encounters. The relationship between Nagi and Shizuka forms the emotional core, mirrored by Naozumi and Touko and by other complicated bonds surrounding the Academy.

Polygon Pictures Leads the Adaptation

Polygon Pictures is producing the animation.

Tadahiro “Tady” Yoshihira serves as director, series composer, and screenwriter, with Hiroaki Ando also directing and writing.

Yuki Moriyama handles character design, Kazuma Teshigahara oversees production design, and Masaru Yokoyama composes the score.

The series uses a pre-scoring production method, recording performances before the final animation is completed.

That approach allows the animation to respond more closely to the actors’ timing, pauses, shouting, and emotional intensity rather than forcing performances into already completed footage.

Why This Matters

1) The wheelchair is an actual combat system

The Tank Chair is not simply Nagi’s means of transportation. Its blades, wheels, transformations, and other mechanisms directly shape the action choreography.

2) The dystopia is deliberately colorful

Ruined cities and violent assassins are presented with bold colors and graphic design instead of a uniformly bleak palette.

3) The violence supports a sibling story

Behind the extreme battles is Shizuka’s attempt to recover the brother who sacrificed himself to protect her.

4) The main trailer establishes the anime’s musical identity

SiM brings aggressive energy to the opening, while Daoko’s ending is designed to leave the series on a quieter emotional note.
