"Silver and iron to the origin. May mana and the archduke of contracts be the foundation. Let humanity's call be my cry for help. Allow a wall to rise against the wind that will fall. 
May the four cardinal gates close. Allow the three-forked road from the crown reaching unto the Kingdom circulate. 
――― I now declare! Your flesh is under me, my fate is your blade. In accordance to protecting the future of humanity, if you are willing to listen to my call, then answer me.

From Chaldea to the Throne of Heroes I call upon you, you who are claded by the seven heavens with three words of power, arrive from your realms, O warrior of Humanity―――!"
