This is the first manga i've ever read.
I was 5 years old that time.
This manga makes my childhood amazing.
This is great manga for kids.
The story is easy to understand.
The creativity of this manga is good to kids.
The art is still good even at this era, this kind of manga don't need amazing art or great art detail.
Because what kids need is an inspiring story, creative story and full of imagination.
But don't think this is just for kids, everybody can read this, everybody can enjoy this.

I couldn't explain it anymore with words.
If you have children, give him/her this manga to read.
They will have an amazing childhood. :')
