Can a comatose hitman wake up only when faced with murderous intent? Bandai Namco Filmworks answered that question by releasing the second main promotional video for the Tank Chair anime, an upcoming television series adapting Manabu Yashiro’s gritty action manga. The newly released footage confirms veteran voice artist Megumi Ogata in the role of Sensei, an enigmatic ruler who commands the Academy. This violent recovery story officially begins its Japanese television broadcast on October 4. [1]
Tank Chair Anime Cast and Premiere
The Tank Chair anime expands its world with this casting reveal, as Megumi Ogata brings distinct intensity to the cast as Sensei, a figure introduced by the production as an absolute ruler possessing unfathomable menace and overwhelming power. The character stands at the core of the Academy, establishing an imposing presence against which the protagonists must measure their strength. Following the casting announcement, Bandai Namco Filmworks confirmed that Ogata will appear in person during a special advance screening event held at Ikebukuro HUMAX Cinemas on September 24. [1, 2]
The broadcast begins in October. Tokyo MX carries the television premiere on October 4 at 11:00 p.m. JST, corresponding to 10:00 a.m. EDT. [1]
Satellite network BS11 expands that domestic rollout by airing the first episode later that same evening at 24:30 JST (effectively October 5 at 12:30 a.m. JST). Viewers across regional Japan receive access shortly afterward, with the CBC channel broadcasting the series on October 5 and MBS scheduling its regional transmission for October 6. Bandai Namco Filmworks scheduled multiple networks to ensure broad national coverage across the initial premiere weekend. The promotional video showcases these scheduling details while providing dynamic animation clips that preview the brutal combat encounters awaiting audiences. These combined broadcasts introduce television viewers to a bleak metropolitan landscape dominated by competing criminal factions and deadly contract killers. [1]
Sibling Assassins and Wheelchair Warfare
Kodansha USA Publishing holds the official English-language license for the source material, describing a high-stakes premise centered on two dedicated siblings surviving in a violent criminal trade. Shizuka handles the contract work. She willingly accepts lethal mercenary jobs across an unforgiving city, yet she does not execute the targets herself. Instead, physical execution falls to her older brother Nagi Taira, a lethally skilled assassin who suffered severe head trauma while shielding his younger sister from gunfire. [1]
That protective act altered their lives permanently. A bullet left Nagi trapped in a vegetative state, forcing him to navigate daily life in a wheelchair (a heavily modified armored wheelchair designed for lethal combat). Yet Shizuka discovered the solitary catalyst capable of piercing his unresponsive condition: Nagi’s consciousness awakens exclusively when he encounters genuine killing intent directed against him. Lethal hostility triggers his survival instincts, transforming an invalid into an unstoppable combatant. [1]
Why would a sister deliberately seek out the world’s most ruthless assassins? To cure her brother, Shizuka must continually thrust him into mortal peril, engineering confrontations where ruthless killers attempt to take his life in sudden ambush attacks. Each violent skirmish becomes a desperate step toward physical recovery. The Tank Chair anime adaptation centers on this unusual dynamic. Minori Fujidera voices Shizuka Taira, while Kōki Uchiyama delivers the performance of Nagi Taira as he battles from his mechanized seat. [1]
Academy Opponents and Supporting Voice Roster
The newly released footage highlights an expanded roster of formidable adversaries and allies operating within this ruthless ecosystem. Gakuto Kajiwara joins the cast as Naozumi Kurosaka, while Saori Hayami voices Touko Kurosaka. These opposing personalities confront the Taira siblings in relentless territorial clashes. The production team also cast Yurina Amami as the eccentric medical specialist Dr. Radio, with Gen Sato voicing the volatile operative Uzu (an absolute authority within the Academy). [1]
Each character brings distinct visual aesthetics and combat techniques to the screen, heightening anticipation for how Polygon Pictures will render their brutal abilities. The Academy harbors merciless warriors who challenge Nagi’s awakened state at every turn. For audiences following the Tank Chair anime in an autumn broadcast landscape that features high-profile premieres like the Overgeared anime setting an October premiere, this action adaptation carves its identity through visceral hand-to-hand combat, heavy artillery, and unyielding psychological stakes. [1]
Voice talent shapes character intensity. Veteran performers Uchiyama, Fujidera, and Ogata anchor the emotional core of the narrative, giving vocal depth to characters pushed to physical extremes. Nagi’s silent lethality contrasts sharply with Shizuka’s frantic determination to keep her brother breathing. As Sensei looms over the Academy with absolute authority, their conflict promises to deliver relentless narrative friction throughout the seasonal broadcast. [1]
Polygon Pictures Animation and Musical Direction
Polygon Pictures oversees animation production, assembling experienced directors to handle the technical complexities of vehicular action and kinetic combat choreography. Tadahiro Yoshihira, renowned for directing Knights of Sidonia: Love Woven in the Stars, co-directs the series at Polygon Pictures while supervising the overall television scripts. Hiroaki Ando, who directed Kaina of the Great Snow Sea and Ajin, shares directing responsibilities and contributes to screenplay writing. Their collaborative leadership brings established three-dimensional CGI mastery to Yashiro’s gritty illustrated panels. [1]
Character designer Yūki Moriyama, celebrated for his work on Blame!, translates the distinctive manga silhouettes into three-dimensional models capable of high-velocity movement. Production designer Kazuma Teshigahara, who previously collaborated on Kaina of the Great Snow Sea, designs the industrial backdrops and specialized machinery. Masaru Yokoyama composes the original score, bringing dramatic orchestral and electronic energy honed on productions including Mashle: Magic and Muscles and Mobile Suit Gundam: Iron-Blooded Orphans. [1]
Music establishes the rhythm of survival. Reggae-punk band SiM performs the television opening theme song titled “DALALA,” infusing combat sequences with rapid percussion and aggressive vocal hooks. Musical artist Daoko delivers the ending theme song, “‘SYNC,” offering a melodic counterweight to the explosive violence depicted on screen. Both tracks provide the Tank Chair anime with a pulsating sonic identity engineered to match its unrelenting pacing. [1]
