Mash Kyrielight

Mash herself was a test-tube baby born in Chaldea in 2000. She was sixteen when she first appeared.

Through her attending physician, Dr. Roman, it was learned that the maximum age she could remain active was eighteen. Her fusion with a Heroic Spirit had not slowed her cellular aging. In other words, Mash could die at any moment—her bodily functions could cease.

Born in Chaldea, she had lived in a sterile room since childhood, which was why she could not go out and explore the world. However, because of her fusion with a Heroic Spirit, her immunity had improved, allowing her to fight alongside her Master in Singularities.

In essence, she was an experimental subject for fusing with a Heroic Spirit—a test-tube baby created through genetic engineering and other methods—and she successfully fused with the Heroic Spirit Galahad. Internally, he was called Heroic Spirit No. 2; No. 3 was Leonardo da Vinci, and No. 1 was Solomon.

With the help of Director Olga-Marie Asmleit Animusphere, Chaldea's staff gradually came to see her as a human being, and with Dr. Roman's help, she became a Chaldea staff member.

Mash had been pitiful from the moment of her birth. She had been diagnosed with around eighteen years old as the limit of her activity.

She was the vessel for Summoned Heroic Spirit No. 2, summoned by the Heroic Spirit Summoning System: Fate.

Although Heroic Spirit No. 2 had possessed her body, he expressed dissatisfaction with this inhumane attempt and refused to help Chaldea.

After that, he remained silent within her body, but he was moved by what he saw as she lay dying and fused with her so that she could live.

Marisbury feared that Mash might betray him, so he kept her in a sterile room at all times. One wall of the isolation room was made of glass, with a small monitoring room outside.

She lived in that room for fourteen years, until at fifteen she was permitted to move only within Chaldea and underwent training as a member of the A-Team, where Master candidates were gathered.

Only after meeting Ritsuka Fujimaru, Chaldea's collapse, and fully merging with the Heroic Spirit to become a Demi-Servant did she finally begin a free working life. That was right—she kept working for Chaldea, with her limited lifespan.

Only in the end did Fou sacrifice his reason to revive her, also removing the eighteen-year lifespan limit so she could be like a normal person.

Speaking of which, where was Fou? He immediately asked Marisbury, "Does Chaldea have any pets? Something like an animal that looks both like a rabbit and a cat."

After thinking it over, Marisbury said, "No one in Chaldea keeps pets, and Chaldea doesn't have a pet like the one you described."

It seemed that Mash had not been born yet. Since Fou was Mash's pet, it looked like he would have to wait until she was born to find out.

Experiment Log

Today was September 16, 1994. To add Master aptitude and Magic Circuits, this artificial insemination used material from an A-rank Master candidate.

The experiment failed. Pursuing quality too excessively had caused failure before fertilization could even begin.

Experiment conclusion: It was recommended that the quality of the Magic Circuits be lowered.

Today, October 27, 1994, Experiment No. XX failed. It either failed at the start of fertilization or during gestation after fertilization was complete.

Many people advised me to give up. After much painful reflection, I decided to continue the experiment. After all, I was the director.

Besides, Mash's birth was inevitable. It was only a matter of probability. The next pull would definitely get her. (Today, Water Morgan barely reached NP1. I'm devastated; Nursery Rhyme ambushed me.)

November 18, 1994, Experiment No. XXX failed. No matter how the plan was altered, the final result was always failure. Everyone advised me to stop.

I remained unmoved, true to my original intentions, stubborn to the extreme.

December 7, 1994, Experiment No. XXX failed. I could not help wondering whether Mash truly had to wait until 2000 to be born.

December 31, 1994. Today was the fifth month of Aoi's pregnancy. No one at home contacted me, presumably because they did not want to disturb me. After another failed experiment, I did not feel like writing anymore. Seriously, what normal person wrote this stuff?

Tomorrow would be 1995. A new year was about to begin. It was about time to go back and take a look, or I would be a scumbag.

January 1, 1995. Although I planned to go back, the experiment could not stop. Before leaving, I planned to personally conduct an experiment. I had always suspected that they had sneaked over from Africa—their luck was terrible.

I handled everything carefully. I had watched it hundreds of times, and with my talent, my imitation was exactly the same. The experiment remained stable after fertilization began, and the fetus developed successfully without any setbacks.

I turned to look at the stunned crowd and could not help falling into thought. Shouldn't I have succeeded much earlier?

Once I left the laboratory, everyone began cheering and asked me to choose the name. Without hesitation, I said, "The child's name will be Mash Kyrielight."

After telling everyone to take good care of her, I boarded a plane and went back.

Once I got on the plane, I realized that the child's gender had not been determined yet. What if she was not my little angel Mash? Forget it, I would ask later. First, I would go back and see Aoi.
