Hasha no Seiten (覇者の聖典, lit. Holy Book of Champions, dub: The Teachings of the Master.) 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.
It first appeared in episode 9, situated in a room of the Soccer Museum. It was stolen by Tenma and the others, but was taken back by Beta in episode 11. Daisuke was turned into a Chrono Stone also because of her, but he could still speak and told Raimon about the contents of the Hasha no Seiten, allowing them to search for the eleven auras.
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.
However, by time traveling to meet these people and then using the Mixi Max Gun, it's possible to form the Strongest Eleven In History by giving their powers to suitable players.
As stated by Toudou Heikichi, Raimon's players are able to Mixi Max with the auras of these people due to Daisuke's influence as a Chrono Stone.
