Polygon Pictures' adaptation of Manabu Yashiro's Tank Chair has a date: October 4, 2026. A new promo video landed alongside more cast, staff and both theme songs, so the fall lineup gains one more oddball action premiere.
Quick answer
Tank Chair (Sensha Isu) premieres October 4, 2026 at 11:00 p.m. on Tokyo MX, followed by BS11, CBC and MBS. Polygon Pictures animates, with Tadahiro Yoshihira and Hiroaki Ando directing. SiM performs the opening "DALALA" and Daako the ending "SYNC."
The premise
Shizuka takes the most dangerous assassin jobs, but she isn't the killer — her comatose brother Nagi is, a lethal fighter who took a bullet protecting her and now uses a wheelchair. Her method for waking him: confront him with killing intent. It's a strange hook, adapted from Yashiro's manga that ran in Magazine Pocket from November 2022 before moving to Monthly Shonen Sirius.
Cast and staff
Kōki Uchiyama voices Nagi Taira and Minori Fujidera plays Shizuka, with Gakuto Kajiwara, Saori Hayami, Yurina Amami and Gen Sato filling out the roster. Yūki Moriyama handles character designs and Masaru Yokoyama composes.

Where it'll sit
It's a niche fall entry, so we're tracking it rather than ranking it yet — once episodes air and votes land, it'll take a position on the SenpaiRanks board like every other seasonal title. For the full season, our what to watch in fall 2026 hub collects the premieres worth a slot.
