Tank Chair 2 - Manabu Yashiro

An assassin in the world's deadliest wheelchair and his devoted sister carve an ultra-violent path to recovery across a slick, dystopic landscape in this action manga that fans of Chainsaw Man, Battle Angel Alita, and Dorohedoro will kill to read! \nFail me again...and you will be graduated. \n \nNagi and Shizuka have managed to avoid a grisly death at the hands of two assassins--siblings from Nagi's past life enrolled at the mysterious ACADEMY. To make safe their escape from this terrifying duo, Shizuka moves them across Guicheng Island, from one safe house to another. But Nagi's whereabouts have reached the ears of the leader of the Academy, an iron-fisted administrator known only as Sensei, who dispatches a prodigy at the art of murder to track Nagi down once and for all: the rampaging rookie, Uzu!\n
