Humanity is facing extinction. In a snow-covered world where water has become scarce, the last habitable lands are located at the feet of gigantic Orbital Trees scattered about the desolated Earth. According to a legend, there exists a sage who knows the secret to producing abundant quantities of water to save mankind.

Ririha, the princess of Atland, uses an organic hot-air balloon to climb to the top of an Orbital Tree in hopes of meeting her country's savior. Once she reaches the Canopy—an area that appears to be an infinite window of transparent ice—she meets Kaina, one of the last men alive on the Canopy. However, she can not find the man she was looking for.

Unable to return by herself to her country, the princess finds a helping hand in Kaina, who is eager to explore the surface world that he thought was empty. As Kaina learns about the war against Ririha's country, the antagonistic technologically advanced nation Valghia, and other perils of the surface, he realizes that his escorting mission will prove more difficult than he imagined.

A series tragically overlooked by the greater community, Kaina of the Great Snow Sea showcases two important qualities that contemporary anime have long been in need of: ambition and potential.

The most impressive aspect of Kaina is how well-paced it's 11 episode run is. The show moves itself along at an incredibly brisk pace, which allows for it's survival themes and character dynamics to be explored with a level of variety that is both engaging and satisfying. This elevates another key aspect of Kaina, which is the scope and worldbuilding of the series. Set at the foot of a great tree bordered by a misty snow ...

I wish there were 1/2 ratings on this site. Because I'd like to give this a 6.5/10. I have given it a 6 because I tend to rate "down". I didn't find the anime "good" but I did find it a bit better than "fine".

I wasn't a huge fan of the animation style, I can sort of see why they went with it for the atmosphere that they were trying to convey, it's just not a style I'm a huge fan of. For work WITHIN the style I think they did pretty okay. The background score was fitting though ...

It is not good. All it has going for it is beautiful visuals and initially intriguing, if nonsensical, world building. The main problem facing humanity is lack of water, though the world is almost entirely covered with ... water -- the titular "snow sea," which is fluffy on the top and simply water underneath .... The longer you watch, the less sense it makes, though it initially seems very interesting. The plot, such as it is, is one you've seen a million times, and there are basically 2 characters: bad guys are simply misguided except for the ridiculously over - the - top main villain. ...
