It took me ages to track down the sixth volume of this manga series about bringing up an autistic child in contemporary Japan, but it was worth waiting for. Here, Hikaru has started to hit puberty, and has to be dissuaded from touching himself or pretty women inappropriately; family and school dynamics continue to be a strain; and we get sidetracked for a couple of diversions, when his father attracts too devoted an admirer at work and a couple of his classmates come to terms with their own fannish obsessions. But the core narrative remains sound, of Hikaru and his mother Sachiko dealing with a world which has not been designed for his needs, and doing the best they can. I have the next volume ready to read.
