No Guns Life 4 Karasuma Tasuku (2020)

Ex-soldier Juzo Inui is a cyborg known as one of the Extended, whose head has been replaced with a giant gun. With no memory of his former life, or of who altered him and why, he makes a living in the citys dark streets as a Resolver, handling cases involving the Extended. His recent involvement with the Beruhren megacorporation has put him on its hit list. When a new Beruhren agent arrives at his office with her own Gun Slave Unit partner, Juzo must choose between protecting his own life and taking on a fellow veteran.
