Twice H. Pieceman (トワイス・Ｈ・ピースマン, Towaisu H. Pīsuman?) is the Master of Saver in the Moon Holy Grail War of Fate/Extra. He was formerly the Master of Caster. He is the primary antagonist of Fate/Extra. At the conclusion of the seventh battle, he can be found at the core of the Moon Cell.
Twice H. Pieceman was born in 1970, and there was a war in his birthplace in the 70's. It was a clash of ethnic groups arranged by major powers as a war by proxy. He was war orphan and was later adopted by his foster parents. He became a prominent scientist in the fields of advanced neurosurgery in the latter half of the 20th century and pioneered the science of digital hacking and he is thought to be the first Spiritron-hacker. He discovered a cure for the disease known as Amnesia Syndrome (アムネジア・シンドローム, Amunejia Shindorōmu?). After becoming a scientist, he still risked his life to save others. In 1999, Twice was called to the city in the Far East to treat victims of the disease and he was killed in a bioterrorism attack.
His data was recorded by the Moon Cell Automaton and became part of the system. After serving in multiple Grail Wars as an NPC, the constant exposure to the human Masters combining with his skill as a Spiritron-hacker eventually caused his data to become self-aware, and he now exists in the Moon Cell as both a NPC and a Master.
After becoming self-aware, Twice became a Master and summoned Caster. He went on to fight in countless Holy Grail Wars, but failed to win the war. Eventually he lost Caster and he prayed for salvation until he was given a new servant. Saver responded to Twice, not because he agreed with Twice's ideals, but out of compassion for his soul. However, once he reached the core of the Moon Cell, he found that, as an NPC, he could not enter the core without being deleted as invalid data. From there, he redesigned the Holy Grail War to the current system and asked each Master who was victorious in the Holy Grail War to wish for the perpetuation of war and the continued advancement of man. However, all the Masters who faced him refused, and thus were killed by him and Saver.
Twice H. Pieceman is in his late 20's with black hair and grey eyes and wears glasses. He wears doctor uniform with black collar long sleeves white shirt with black, grey, and light blue tie and grey sweater vest, white lab coat, black gloves, black pants with grey lines, and black shoes. His expression is blank that makes him look unmemorable similar to a NPC and he has the feeling of "nothingness".
As someone who was a victim of war, he concluded that his life was a miracle and he has an intense hatred of war; he also experienced shell shock. When he was a student, he studied the history of humanity and this is when he realized the betrayal of the makeup of history. He saw images of depicting war and he was overcome with severe panics attacks. He got involved in war in order to end them and saw many battlefields, the horrific event perpetuated by humanity. What drove him was not his sense of righteousness but it was the question "Why was I the only one who seemed to hate war?". He can't deny war, however, as he saw great strength in humanity when conflict emerges. The mortal Twice's dream was to see mankind engage in a grand endless war of mutual extinction.
—Twice H. Pieceman
The NPC version finds the mortal Twice to have been ill: There was no reason for him to risk his life so foolishly on the battlefield and he struggled to find reason in war. Twice is a pacifist who hates wars and cannot forgive it, but at the same time believes that humanity requires war to advance and evolve. He concluded that war is a necessary evil. The future was corrupted, the spirit of mankind has stagnated just like the world. To him, the Holy Grail War existing within the Moon Cell is a microcosm of the constant bloodshed that transpires in the outside world. The participants slaughter one another in the hopes of having the Grail grant their wish, all the while feeding information to the Automaton. Twice accepts this as survival of the fittest and believes that such a process is essential for humanity. He used the Moon Cell to manipulated information and manufacturing information causing terrorism and violence in the real world. By using Moon cell record and his ability to divine the future, he wants to bring Armageddon. He wish to instigate a war so that anyone can survive. Having everybody fight in a war, mankind's consciousness will be forced onto the correct war.
Caster claims that when Twice was her Master, he was too kind and gentle for the Grail War. When Twice meets Caster he claims that he is not the same person as he was when he was Caster's Master.
After Hakuno's Servants defeats Leonardo B. Harwey and his Saber, they are permitted access to the core of the moon. Once they arrive, they find Twice sitting atop the coffins of the Masters he has defeated. He awaited for Hakuno and claims that out of all Holy Grail War, Hakuno is the most extraordinary master. Twice explains his backstory to Hakuno and makes the same request as he did to the other Masters, unaware that they are an NPC as well and likewise cannot enter the core without being deleted. Hakuno and their Servant reject Twice's philosophy and do battle with him and Saver. After Saver is defeated, Twice deletes himself, staying true to his beliefs about survival of the fittest.
In the manga version, Saver defeats Saber with Amita Amitabha, but Hakuno uses his final Command Spell to forcibly re-summon Saber who slashes Twice, resulting in Twice getting deleted.
In the beginning of Chapter 7 - I love you, Twice contacts Hakuno's subconscious and becomes a voice of encouragement.
Past incarnations of Twice and Caster appear as a bonus boss in Fate/Extra CCC.
Caster comments that Twice is very similar to Hakuno as they started out very weak but he could not fully use all his abilities due to his gentle nature. Being a NPC means he can continue on even after his defeat or death.

 Fate/EXTRA material - Encyclopedia: Twice H. Pieceman [Circumstances]
A ghost that already turned into a phenomenon.
The fragment of a messiah that hates, endorses conflict.
"This future is mistaken… someone has to start it over."
The ghost drew such a conclusion about the thesis of EXTRA as a whole - "confrontation against stagnation".
This is a fight against stagnation, the evil nature of humans.
Will you advance while shedding blood?
Will you advance while taking someone's hand?
After despair, will you reject (travel all over) this?
After despair, will you affirm (settle) this?
The ghost inquires about such right and wrong.
As a responsible party born in the past, reflected in the present.
"The world has entered in a impasse.
This future has already approached a dead end. Humanity is unsightly ending halfway without bearing fruit."
Humanity has already ended.
This "stagnation" itself is proof.
Rin thought that this came from the rule of Western Europe Plutocrats.
That Leo and the others were suppressing the progress of technology, the undulation of emotions to their own convenience.
Leo too had such self-awareness. That the Plutocrats are controlling the world in this manner.
Howerver… Leo never told Rin until the end.
The Western Europe Plutocrats has made arrangements so that society would stagnate, but other than that no definite choice has been produced so far.
"The halt of the world occurred because you people desired so."
Nobody wishes, has any interest in the future and the likes.
Rather than going forward, it is much more comfortable to stand still.
To begin with… humans are enough happy as it is.
More progress than this, for sure that is something unnecessary - the consciousness of people say so.
"How absurd. Then there is no meaning to this. If it was just about wishing for happiness, it would have been better to remain as animals from the beginning. You people - we all - have shed much blood while seeking for something greater than happiness."
The ghost resents that weakness.
Why are people so weak, when they are that much strong?
Such ending, is it really worth 2,000 years?
"Humans that have forgotten conflict will just disappear. Struggle for existence is indeed the basis of life. The means to survive, in the true sense of the word."
Yes. Conflict is indeed the path of progress.
Kill. Open a path (Spread). Steal. Flourish.
If you kill this planet, then leave this planet behind and reach the cosmos (sky).
That is the bare minimum responsibility of humans.
"And, you yourself are its crystallization.
Contemplate that growth. Conflict nurtured you. Predicament changed that flesh and blood into steel. It let you surpass even first-rate hackers. Yet… you, who knows its preciousness, will reject this strife (wish)?"
Before the eye of the moon, two ghosts confront each other.
They are both humans from the past.
Two of the few people that can express objective impressions about this future.
The king of conflict rejects this future.
However, you do not hold such point of view.
"Even without finding any value in this era.
Even if this future is all somebody else's problem.
Even if the time ahead that we dreamed about is a foolish dead end. I cannot reject the life of the people that live here."
"You approve this future?"
"No, I'm just like you. I cannot approve it.
…however, I still cannot bring myself to hate it either."
The observation mechanism that became the stage for the Holy Grail War.
The reason why its virtual world has the image of a sea.
If the basis of life is conflict, then the basis of the eye of the moon is to watch over.
That way of being was unconsciously understood by the Masters who arrived at the moon.
But only he, who managed to reach the Nucleus faster than anyone else, did not understand the strength of that way of being.
"…even so. Stagnation (this place) is our reality."
Tragedies that occurred cannot be changed.
The responsibility for stealing must be fulfilled.
While accepting the premonition of defeat, the fragment of a messiah takes up his sword without yielding his pet theory.
"Thinking back, mankind has already expired its adolescence.
Until the 1900, it was the growing period.
But, after experiencing the adolescence--- the immature era meant to follow it, the golden age that was finally supposed appear was practically non-existent.
Like a decomposed fruit.
The most rich and prosperous period was entirely missing.
That, was too much sinful.
If we don't leave behind an outcome enough to recompense the lost things, the fostered costs, everything will turn into lies.
This future is mistaken. Mankind has to start things over again. Small disputes are no good. Without a struggle for existence that turns all into related parties, our eyes, our consciousness will not grow."
Humans are more amazing than that.
Life, mankind must go to a place that even the humans of the past cannot imagine.
Such ideology of the innate goodness of man has pushed up this ghost to the level of a messiah.
Although his views are elitism-like, they are also correct.
Indeed, the humans of this era are worn out.
They are losing interest. They are giving up. They have long forgotten, what is to dream about the future.
"To choose that is responsibility of the people who live in that era.
Twice H. Pieceman.
The era which you were supposed to protect, has passed away long ago."
The curtains of the battle rise together with the words of parting.
The final battle that overcame the seven seas.
Those who knows its ending, are only the Mooncell and the player.
