Yume Onna is written by Hideo Yamamoto, who is most well known for his Ichi the Killer manga. The art is by Hiroya Oku, creator of the Gantz series.

The story revolves around our main character Lime, who after reading an article about lucid dreaming decides that she to try it. The story focuses on dreams as the main topic ,and because of this we are treated to surrealistic imagery and situations (think giant naked people and whales floating through the air).

The characters are very one dimensional, with not enough time to really develop them. If this had more chapters focusing on the character's, to try and develop them and give them more substance the score could be much better.

The art by Oku is fine, by no means is it his greatest work, It is however... not awful, I personally think it looks quite nice. Specifically some shots from the dream state Lime is in.

Overall I think the current score of 6.47 is fair. By no means is this an awful manga, it's decent. It is however, not memorable. It is very short and you will complete it in under 20 minutes. This premise for a manga is very promising, but in Yume Onna it is not reaching its full potential.

I did a short talk about the manga if you want to hear more about it that I may have left out in this review :
