I didn't know what to expect when I saw season 1 of this series at my local library. But since it was free to borrow, I decided to try it.
My wife and I found the story surprisingly interesting and pleasant in some aspects, hence I decided to buy the whole collection (2 seasons, movie, 4 OVAs).
One of our favourite parts of the series is the end theme song "Dango Daikazoku".
If you can recommend any other anime series with similar levels of non-violence, plot, and theme songs that make you feel peaceful and happy, I would appreciate it. Thanks!
