I wouldn't have read this if I had noticed it was under 'shota'.
I never liked shota, I never cared for shota, and after reading this through I still don't like it one bit.
Like I said, however, I got hold of it a minute too late. So I kept on reading, mostly because the main character, Shou-chan, was sweet to the verge of tears.
The first part of the whole volume - up to the 4th chapter, I'd say - was the very best one. The first rape scene was... brutal. No, not brutal in a graphic sense, just overwhelming I think, with those painful, transfixed and unpredictable moments of silence. This was also when the art was at its best, although the style has a significant particularity to it, with very clean strokes and lovely expressions too. I think the artist overdid Danzou's height though, which wasn't exactly necessary. I had to keep reminding myself he was only a freshman in junior high... I know it's normal, I mean, in 6th grade I was a shorty and my best friend grew taller over summer. But the difference here was a little disturbing...
Still, up to the 4th chapter or so, like I said, I liked it very much. But it bothered me that their relationship remained sexual in the end. Shou-chan's progression from fear to hate to love was... too quick, which utterly crushed my expectations after the first chapters. Like FeyPhanton I agree that a last time-skip would be definitely appropriate. 12 year-olds should not be having sexual intercourse, no matter how aware of their feelings they are. Neither of them conveyed enough "maturity" for me to believe in such an ending. I mean, can Danzou really control himself or is he being able to behave a result of Shou-chan's acceptance? Because, honestly, they are just kids. If anything goes wrong, whatever little thing, as soon as they hit really puberty (around 15) Danzou may go bersek.
I still felt unsatisfied with the ending. That's why I don't like Shota.
On of the first part and the art style, I'll give it a 7.
