Fist Of The North Star, Vol. 1 by Buronson

In a brutal post-nuclear wasteland, a stoic master of a deadly martial art wanders the ruins to protect the weak, using precise pressure-point techniques to topple tyrants and violent gangs; after a rival betrays him and abducts the woman he loves, he awakens with a carved fate and begins a harsh journey across ruined towns, rescuing a vulnerable girl and a streetwise orphan while confronting cruelty and asserting his grim justice.
