The Hasha no Seiten is a notebook in Inazuma Eleven GO Chrono Stone, containing information about the "Strongest Eleven In History". This was the last notebook written by Endou Daisuke, containing the secret of forming the Strongest Eleven In History. Daisuke himself was known as Master D by the people in the future. The contents in this book are about the powers that would make the Strongest Eleven In History. Because they all belonged to either historical or mythical figures (or nonhuman in some case), the Strongest Eleven In History can't be gathered up by normal means. Thus, its concept was an impossible dream of Daisuke. But here, assembling the "Strongest Eleven in History" is possible.
