The strongest assassin lies unconscious until murderous intent wakes him. The TV anime Tank Chair, adapted from Manabu Yashiro’s manga, starts on TOKYO MX at 11 p.m. on Sunday, October 4. Bandai Namco Filmworks posted a cast comment video on October 3, the day before broadcast.
Nagi Taira was shot while protecting his sister and has not regained consciousness. His sister Shizuka seeks the murderous intent that can awaken him by taking on powerful enemies in a kind of “rehabilitation.” Polygon Pictures produces the animation, co-directed by Naohiro “Tady” Yoshihira and Hiroaki Ando.
Voices first, animation second
According to the official site’s report on a September 24 preview screening, the team used pre-scoring, recording the voices before building the animation. The directors said they sometimes redrew storyboards to match the performers’ acting.
Koki Uchiyama, who voices Nagi, said the recreation of the manga’s streets overwhelmed him. Mion Fujidera, who voices Shizuka, noted the attention paid even to small movements.
I cannot wait to see how the action I performed with all I had turned out when it airs.
