The Desert Punk, the Demon of the Desert, the Kanto Desert's Number One Mercenary, Sunabozu is the pint-sized protagonist of this series. Desert Punk is the "hero" only because he's the lead character. Chasing after women and money are his entire life and he intends to get both through being the best mercenary, do-any-job handyman in post-apocalyptic Japan.
The character is unique in that he will become obsessed with something at the drop of that hat, but that characteristic is not the standard deus ex machina that writers usually use it as. He'll obsess over a gun, get the gun, and lose the gun and it won't have to do much with the plot. Obsessing over jobs gets him nearly killed several times, such as obsessing over destroying a tank so much that he attacks with with nothing but a knife after several failed attempts.
Anatomical and gross out humor are very common in the series, but funny. I expanded my vocabulary for slang for breasts by watching this, even noting a "Tits McGee" reference from Anchorman.
If you like your heroes callous and immature, yet still adventurous and exciting, this is the series for you. Harder edged than Lupin III, but softer than Hellsing. I know that's a weird location, but that's where the tone of the series lands. Orphans are sold and toilets are blown up, but hey...
that's life in the Kanto Desert.
