Hasha no Seiten

Hasha no Seiten (覇者の聖典, lit. Holy Book of Champions) is a notebook in Inazuma Eleven GO Chrono Stone, containing information about the Ultimate Eleven.

Origin
Written by Endou Daisuke, it's a book containing the secret of forming the Ultimate Eleven. Daisuke, the writer, was referred to by the people in the future as Master D.

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. Because of her, Daisuke turned into a Chrono Stone, however he could still speak and told Raimon about the Hasha no Seiten and the Ultimate Eleven, allowing them to search for the eleven auras.

The Powers
Daisuke has written in this book the powers that would make the Ultimate Eleven. Because these powers all belong to historical figures, they can't be gathered up by normal means. Thus, the concept of the Ultimate Eleven was an impossible dream of Daisuke.

However, by time traveling to meet these people and then using the Mixi Max Gun, the Ultimate Eleven can now be formed by giving their powers to suitable players.

As stated by Toudou Heikichi, Raimon's players are able to Mixi Max with the historical characters due to Daisuke's influence as a Chrono Stone.
