No Guns Life 2 Karasuma Tasuku (2019)

Ex-soldier Juzo Inui has one question: who turned him into a cyborg and erased his memories? After the war, cyborg soldiers known as the Extended are discharged. Juzo Inui is one of them, a man whose body has been transformed and whose head has been replaced with a giant gun. With no memory of his previous life, or of who replaced his head and why, Inui now makes a living in the city’s dark streets as a Resolver, taking on cases involving the Extended.
