Why it’s a Weeknight Watch

With almost no lasting buzz and soft box office, it's a mixed bag. Fine if it's on; don't plan your night around it.

Based on critics, audiences, awards, box office and buzz. Details below.

Is it for you?

Who'll love it
If you count yourself among manga readers and spy-story fans, this one's for you. It's anime, with all the big emotions and big action that comes with it. Nobody is quite who they seem.
The mood
Funny with heart, romantic.
The pace
Paced for all ages, at 2 hr 18 min.
What might put you off
  • It's in Japanese, so expect subtitles (or a dub).
  • Skip it if you can't get past animation (your loss).

A small, lone Kappa miraculously survives over 200 years into modern day Japan, when he is found by young Koichi. Coo, who is secretly adopted by Koichi's family, searches with his new human friend for unpopulated places in hopes of finding any remaining of his kind.
