The Port Town, Libra City.
Upper Town is the center of politics, economics, and culture and is where all of the wealth is concentrated. Outside is where crime and corruption runs wild where no one trusts anyone. Between those two areas is a massive canal that separates the two and is spanned by a single bridge. The way this town is constructed, is a realization of what human discrimination looks like.
Sonia is a young, female detective who has just moved from Upper Town to Outside for work, chasing after a few cases. That is when she meets three hideous beings how fight to protect humanity. ‘Just what are they…?’ she wonders...
These three monsters known as youkai ningen (demon humans) live, concealing who they really are, while each bearing their own feelings and thoughts. BEM wants to become human himself and fights against evil that would befall humans. Bela looks up to and desires to become human herself and attends school in order to understand humans better. Belo has dove headfirst into the world of gaming, taking a philosophical view of both humans and the world. With every incident, they come into contact with humans, get hurt, and worry. They fight for the sake of humanity, however, due to their horrible form, they are something that humans will never accept.
There is another who is searching for these three beings. She has her thumb on the concealed assembly that controls Libra City from the shadows. But just what is her goal as she tries to get her hands on these three?
Hole—a dark, decrepit, and disorderly district where the strong prey on the weak and death is an ordinary occurrence—is all but befitting of the name given to it. A realm separated from law and ethics, it is a testing ground to the magic users who dominate it. As a race occupying the highest rungs of their society, the magic users think of the denizens of Hole as no more than insects. Murdered, mutilated, and made experiments without a second thought, the powerless Hole dwellers litter the halls of Hole's hospital on a daily basis.
Possessing free access to and from the cesspool, and with little challenge to their authority, the magic users appear indomitable to most—aside for a few. Kaiman, more reptile than man, is one such individual. He hunts them on a heedless quest for answers with only a trusted pair of bayonets and his immunity to magic. Cursed by his appearance and tormented by nightmares, magic users are his only clue to restoring his life to normal. With his biggest obstacle being his stomach, his female companion Nikaidou, who runs the restaurant Hungry Bug, is his greatest ally.
Set in a gritty world of hellish design, Dorohedoro manages a healthy blend of comedy and lightheartedness with death and carnage. Taking plenty of twists and turns while following the lives of Hole's residents, it weaves a unique world of unearthly origin and dreary appearance not for the squeamish or easily disturbed.
