From Kotonoha:

Seventh grader Hayashi Renei is troubled by a strange dream: Her dead brother, who was killed in an automobile accident, comes back to life as Coo. The dream comes again the following night and then every night thereafter.

Coo's world is a cruel one--crueler than the real world, even--with its own share of pain, suffering, and sadness. Renei is searching for her house with her brother and others whom she meets in Coo's world so that she can return to reality and the land of the living...

Nosedives in chapter 4

It was enjoyable for the first three chapters, being a cute, quirky adventure manga with some symbolic depth in the background, but in chapter 4, the author wants to make ABSOLUTE sure you get how brilliant his metaphors are, and the story of the first volume culminates in an exposition dump spelling out everything and taking away any subtlety the manga had. The second volume continues the trend of being baby-ingly obvious with it's "hidden" meaning, but also adds a bunch of silly and unnecessary melodrama simply for the sake of continuing more of the author's masturbatory "Growing up is so DEEP and COMPLEX" wank. Don't bother with this one, all that awaits is disappointment.

Here are the good points about this manga:

Mysterious story;
Realistic characters;
Lovable characters;
Great drawing;
Story can be enjoyed on two levels -- adventure, and symbolic depiction of basic life issues;
Ultra-cute girl main character.

And there's nothing wrong with it at all.

A surreal, imaginative foray into a female preteen's psyche where some themes of life, mainly death, crushes and a little bit of existentialism, are dealt with unusually.

Volume 1 begins with the realistic exploration of the subconscious during our resting state as the young protagonist tries to cope with the heavy burden of death and get out of the rut created. The protagonist behaves her age believably and throughout the series, manages to develop and reveal her depth, a flawed being nevertheless trying to uphold one's virtues. Likable. The world itself is one strange one indeed, pedalling backwards to resemble a previous type of civilisation in a primal, if not equally fatal setting. Strangely immersing, it parallels the "real" world and manages to incorporate many moral messages. I liked Volume 1 more than Volume 2 because Volume 2 was when the not-so-needed drama and the shift of tone begins.

Volume 2 starts to introduce a more prominent antagonist and tries to answer the questions Volume 1 brought up. Also, the romance part, though not one of the main aspects of the series, was also touched on more deeply. Believability for this volume was a little hard because for me, some notions for me were already set in volume 1, thus dulling my enjoyment. It was still fun as it retained the usual storytelling formula from Volume 1 and used it well.

Great read overall, do check it out if you like offbeat, surrealistic adventure themes.

In the beganing we can tell that something is not right but the mistery will be soon resolved. The art is realistic and very pretty and... I don´t can tell much more you have to find out. I really don't understant why I'm the first person commented in a beautiful manga like this one.
