This collection of short stories from Yuki Urushibahara is far from the quality of other mangas she has done. Like most of the one-shots of this style you can tell the difference of quality between the stories, but in this volumen that gap is huge.
The mayority of the stories are extremely brief, not having enought time to develop any minimun plot. Both mushishi chapters and the one and the beginning stand out and carry this volumen due to the low rank tales in the rest of the book. This last ones were the mangas she wrote when she was starting her career, so is
understandable the lack of creativity.
Don't get wrong with the author, she is really good mangaka as she has showned is Suiiki and Mushishi.
