The book flits between them as they work together to change things. Hojo's violent rise through the Yakuza swiftly makes him an untouchable power within the gang. The police have no evidence against him but are always watching him closely. Meanwhile Asami's climb through the arcane political system has him butting heads with the old men governing Japan.
The book accurately reflects many facets of Japan with accuracy: the LDP's 'democratic' rule of Japan with only token opposition and no meaningful representation of the will of the people in the government's actions. It's also credited with cleaning up the image of the Yakuza: when the book portrayed the scruffy real-world yakuza as suit-wearing gangsters with honour, the real Yakuza started emulating the book and wearing suits themselves.
It's a fascinating story written by Sho Fumimura (Fist of the North Star), with believable situations and all too real frustrations for the main characters.
The art, by Ryoichi Ikegami (Crying Freeman), is mostly excellent. He relies too often on clip art, or traced photographs, which compromise the beauty of the people he illustrates, but it is never really annoying.
The books were released in English by Viz, with an exceptional translation by Matt Thorn.
I cannot recommend this book enough.
