Mythology Mystic Code of Wrought Iron (錬鉄の神話礼装, Rentetsu no Shinwa Reisō) is a a mystic code that gives No Name the power of the origin of human civilization. For him, it is the representation of the will of all the Unknown Soldiers/Unnamed Heroes in history.
As a result of analyizing the data from the Ten Crowns they gained from Robin Hood, Rani VIII and Rin Tohsaka acquired rights to access "original power" from the Moon Cell. The Ten Crowns is the beginning of human history, the dawning of the light of civilization. To summarize, it is the power of the Origin that began the human genome. It is something all human beings hold within them. By entering No Name's virtual mind/body to access the Heroic Spirit core directly, Hakuno was able to reach the heroic spirit's root that the Moon Cell had sealed away, and release the Mythological Mystic Code. This is an origin that even the person themselves, in this case, No Name, can never know. The farthest point that became the cause of the birth of the entity known as No Name. In other words, zero.
By removing the limiter placed on him, No Name would be able to acquire the same level of "fundamental truth" as BB due to now being able to raise his spiritual rank according to his will. Because this is a very powerful engine, this power places much burden on the Servant. Sakura claims that the basic Servant frame is not capable of withstanding the power output of the Mythological Mystic Code, and she asks Hakuno to limit its use to one time only. With this power alone, the student council estimated that No Name and Hakuno would have a 0.9999% chance of victory against BB. In order to help No Name and Hakuno in the final battle, even if just a little, Rin Tohsaka redirected all the power that had been previously protecting the school building to stop BB and the Alter Egos from entering, and all the resources that comprised the building were transferred to No Name, to further empower him. By the point No Name finally faces BB, his power is increased to the same rank as hers. Being able to match BB in capability and rank of powers wielded, the battle between the two becomes rather competitive.
He becomes capable of feats like moving faster than light.[1]
