Where can I read the Inazuma Eleven manga online? So far, I have only found chapter 1 of the Inazuma Eleven manga online. Is there any site where I can read all of the chapters online and legally?
Unfortunately, there are no official English-language localizations of the Inazuma Eleven manga in existence, in print or online. 

You can easily verify this by:


checking the Wikipedia page for Inazuma Eleven (manga), which does not list any English-language localizations. 
looking at the AnimeNewsNetwork encyclopedia page for Inazuma Eleven and seeing that this page also does not list any English-language localizations.
searching Amazon for "inazuma eleven manga" and seeing that you get no hits that are actually manga.
