As a manga author of a semi known series, Hirahara Daichi has the talent for coming up with stories, but is incredibly lazy and irresponsible. That leaves his two daughters, middle school student Ayumi and the even younger Sora, to pick up the slack. With the help of the assistant, Akane, the two kids are forced to draw and complete the series every month if they want an income for the household, a task no child should burden themselves with. On top of that, they must do this without people finding out because it will ruin the credibility of Daichi as an author and put a stop to the series. If being a teenager wasn’t hard enough, add to that the pressure of meeting deadlines for a national comic magazine.

The series takes place at a certain Japanese location, where a girl moves in with her aunt to a new house after experiencing some more or less shocking events back home. There she meets a boy named Fuyuki, whom she spends a lot of time with from then on. The special thing about Chinatsu is her voice, a voice which many seem to have heard before, but from where? What's so special about this girl, and what'll happen in the future?

This manga follows the unfortunate life on an extraordinary swordsman - Inoko Gennosuke.
Gennosuke was born in a social group called 'buraku' that was considered to be the filth of society, and because of that he was forced to live a life of misery.

From Entropy:

In the languid hours of yesterday, I went to the tangled grasses near the river, so tangled that humans don’t often venture there, and had heaps of fun playing alone. As per usual, I had had a glass of sue-ju with grandmother in the morning, and drunk, I grabbed a towel and stumbled my way up. There won’t be any watchers, my body thought, and it slipped so easily into the water. Floating in the clear and pretty water I looked at the sky, saw the floating clouds. Hee hee… in that small space I even had a go at swimming like the pros. If you sit on the rock and rest for a bit you can see the small sand-colored fishes swimming around. Even such small creatures made shadows on the river bed and moved around. Yeah, every day I play at being a mountain wizard. Whether the axe handles decay or not… violets.
