I first heard about the series many years yang lalu when i was about 13 from my best friend and his nephew who talked about the tampil quite a bit when of the times i was there. but i really understood then was something like the main character being child but super smart. I seen the manga's everytime i went to the store and wanted to buy them but never did. it wasn't until i was sick in college and needed something to watch that i finally decided to watch. and now i am addicted and have seen every episode.
