Tank Chair is a Japanese manga series written and illustrated by Manabu Yashiro. It began serialization on Kodansha’s Magazine Pocket website and app in November 2022. Kodansha USA is releasing it in English, describing the story of Volume 1:

Living on Guicheng Island, called “the most dangerous town in the universe,” is no easy task. Genetic doping is common for gangs to gain ultimate power. Shizuka, a young girl, takes on the most dangerous of assassin jobs, but she’s not the one doing the killing. Rather, it’s her brother, Nagi, a strong assassin who took a bullet to protect his sister, leaving him in a comatose state and having to use a wheelchair. However, Shizuka has figured out the key to waking her brother up: he must be faced with murderous intent! Thus begins a violent journey of recovery, battling the most dangerous foes!
