Hello readers!

I couldn't help but think of this new idea while trying to write for my other stories. Please forgive me for not continuing my other stories :( I couldn't resist! This may be a one-shot that I may no continue, but please enjoy what I wrote here.

Prologue

Touka Aozaki was very UNHAPPY. Her son had run away and left a note saying he was going to prove that her magecraft was superior than Aoko's magecraft. If her son had not run away from home, THEN Touka might have been happy… But that was the main focus of her attention right now.

The legendary puppet maker quickly made through the various defenses that layered the destination that her son had decided to run away to. Touka was relieved to find that the formidable and complex defenses did not show any signs of attacking any intruders. If her sister hadn't doted her son enough to have placed him on the list of authorized users then her son would have long been killed before he could even make it past the first layer of defenses.

She made her way into the heart of Aoko's Workshop with mixed feelings. Touka had a love/hate relationship with her sister that was so strong that they would have likely remained forever estranged if it was not for her son. At the worst point of their estranged relationship, they might have killed at the sight of the other.

Touka entered a room and her heart stopped when she saw a familiar sight that accompanied her younger sister, Aoko Aozaki, when Aoko used Fifth True Magic.

She quickly began to search the research logs that dotted the room. Books filled with information about various magic experiments that Aoko had done in this Workshop. The more she read the greater Touka's anxious became until she stumbled on her son's writing.

Fifth Magic doesn't seem too bad…

Her expression darkened when Touka saw that her son had betrayed her! Why was her son that had always bragged with proud that puppetry was far superior to Fifth Magic?!

Touka's mood became even worse when she found more of her son's writing until she reached the last recorded notes of her son.

I did it! I managed to replicate Aunt Aoko's Fifth Magic to create a portal.

"You are going screaming to be punished," growled Touka as she slammed the notebook shut.

The legendary puppet master was about to investigate the complex magic circle standing in the middle of the room when a portal formed and unexpected her son stumbled into the room.

"Shirou are you okay?!" Touka screamed as she rushed to catch her son, all thoughts of her anger melting away as her motherly instincts took over.

"Mum… Is that you?" asked Shirou in a tired voice, almost as if he didn't believe the sight, smell and touch of his mother. It was as if Shirou hadn't seen his mother in years, and something told Touka that might actually be the case.

"Of course, it is me! Who else would it me besides your mother?" Touka berated her son as she carefully nursed and inspected him. "Shirou, what happened to you? Your current body isn't made out of flesh and bone… The craftmanship and material is very different from what I know, but it is no doubt a puppet body…"

"That's going to be a long story for me to explain," replied Shirou softly. "A story that would take days to tell."

"We have all the time in the world," said Touka as she affectionately touched her son. "I want to kn-"

"Mother!" screamed several voices mixed between shock and veneration.

Touka suddenly felt as if she had become a figure of religious worship given the current behavior she started to see the newcomers show. She might have found such a sight as amusing or annoying if she wasn't too busy inspecting the bodies of the newcomers. Like her son's current body, they were made out of material and construction methods was very different from any puppets or artificial magical lifeforms that Touka was familiar with.

"It is my honor to meet you, Mother," said one of the most well-dressed newcomers that seemed to be the leader given how all the newcomers seem to treat her with the most respect. "My name is Commander White, the leader of YoRHa."

"Mother? I don't ever recall giving birth to any children besides my Shirou?" Touka couldn't help but ask.

"They are something akin to the descendants of your later puppets that eventually develop full sentience. All later androids treat you mother as their creator and progenitor," explained Shirou.

"Why do I sense time travel is involved here," muttered Touka as she recalled that might really be the case as she was within her sister's Workshop that experimented with Fifth Magic, which time travel was one of many aspects related to the True Magic. Shirou started to laugh nervously and Touka looked to her son. "You better explain everything. I don't want a single detail left out!"

Several Years later.

Lev Lainur Flauros crackled in laughter as three thousand years of patience and carefully planning was finally going to bear fruit. Even for an immortal, three thousand years was an exceedingly long time and he was finally not going to hide like a scared mouse. He was going to act without any limitation on his actions and he was going to unleash the magnum opus of the 72 Pillars.

His human persona, Flauros, started to act up again. Lev laughed at Flauros's pathetic last attempt to stop him. Flauros had tried to prevent the extinction of humanity but proved to be futile. He had crushed Flauros before Flauros could suicide and foil Goetia's 3,000-year-old plan to destroy humanity.

Lev taunted his human persona before he was about to press the trigger that would initiate explosions that would cripple or destroy Chaldea from acting on its mission to safeguard humanity and announce to his fellow Demon Pillars to begin the Human Order Incineration Ritual...

"Lev, you might be a good friend to my sister, but that doesn't mean you will be forgiven for trying to kill me, my husband and children!" screamed a familiar voice that scared Lev and before he could react Lev took a nuclear explosion to the nuts that eventually engulfed him and a large section of Chaldea HQ.

"Detecting the presence of Miss Blue."

"Miss Blue!?"

"We gotta to get out of here!"

"Director, please give the order to evacuate Chaldea!"

"What are your orders, Director?"

Olga Marie Asmleit Animusphere sighed as she pinched the bridge of her nose. At this very moment, she almost wished her entire crew working in Chaldea's Command Room were androids. Androids in their programming were near perfect replicates of the human mind, but their mentality was so much sterner than many of her human staff.

"We are not evacuating this base unless we have no other choice!" snaped Olga as she started to give orders to coordinate Chaldea's response. "I want to know more about why Miss Blue is here and what caused the entire building to shake."

"The cause of the rocking seems to be an explosion. Preliminary scans show that it was a nuclear explosion," reported an Operator Model Android calmly while continuing to type away at her console.

Olga shuddered as she imagined what had forced Aoko Aozaki to use her infamous, and now legendary, nuclear magecraft. Miss Blue rarely ever needed to use her nuclear magecraft given the sheer destructive power of her regular arsenal of magic spells. Only something on the level of a Servant or Dead Apostle Ancestor would require such powerful firepower.

"According to SHEBA current scans, Miss Blue is still at her family home in Japan."

"If Miss Blue is at her family home then how did a nuclear explosion occur at this base? I don't recall her having the ability to teleport her magic spells," responded Olga.

"I am detecting another, quickly fading signature of Miss Blue. This one seems different from our current records. The second Miss Blue's detected Spirit Origin seems more older…"

"Great… One Miss Blue is already difficult as it is, but another one, likely from the future… This is starting to become ridiculous…" groaned Olga before she took a deep breath to regain her composure. "Keep on eye on the second Miss Blue. I want to know any new developments the moment they happen. Dispatch several combat androids to investigate the sight of the nuclear explosion."
