To start off, I won't reword what has been said over and over about Kodocha -- that it's about hyper child actress Sana Kurata's troubles with Akito Hayama, the imposing boy who threatens to turn her classroom into a "barrel of monkeys." That description is just so much smaller than what Kodocha really is, especially since the way Sana and Hayama interact throughout most of the series has nothing to do with that description.
At its core, Kodocha is about people (kids in particular) learning to live in a sometimes harsh world, changing as they interact and make mistakes by sometimes running away from their problems and each other like the idiots most of us are. Except of course that they are all crazy, animated, and too funny to watch while drinking soda.
The best thing about Kodocha is that its characters are unique and have a great deal of depth. Even many of its large cast of secondary characters, although they are all in one way or another hilarious weirdoes, are complex enough to be difficult to write about in a way that does them justice. Kodomo no Omocha's characters are its greatest strength, and they are a big part of the reason a series 102 episodes long can manage to remain fun and addictive.
Kodocha is like its main character: unique, hyper, hilarious, yet with a surprising amount of sensitivity and introspection that somehow fits in perfectly with its insane personality.
