Jikai Yokoku "No Guns Life"

In a world where advanced cybernetic technology has transformed society, Juzo Inui is a Reshaped—a human whose body has been heavily modified. With a giant revolver for a head and a mysterious past, he works as a problem solver in the city, taking on cases that involve other Reshaped individuals. His life takes a turn when he meets Tetsuro Arahabaki, a young boy who holds the key to a powerful secret.

As Juzo investigates the circumstances surrounding Tetsuro, he becomes entangled in a conflict involving the powerful Berühren Corporation and its control over the Reshaped. With his own memories fragmented and his unique abilities, Juzo must navigate a dangerous web of conspiracies and confront the truth behind his own existence.
