Nezu was having a great month. In the first week, the Midoriya boy had mostly been Mordred. 'Actually, I should start using the word "system" to describe the Midoriya child.' A person with D.I.D. is referred to as a system because they are more than one person who controls a body, each carrying out different functions, be they good or bad, mostly good. It's like if a beehive were an animal instead of a construct for bees.
Anyway, the Midoriya System has had Mordred in the driver's seat for most of the first week they were here. Quite a fascinating character! The personalitie' insistence on being male, despite their surprise at their new tool — for lack of a better phrase — it was quite funny. It's clear that despite Mordred's use of male pronouns, they are, in fact, mentally female.
During the second week, Nezu got to use some of his super-secret inventions to investigate the Midoriya System's Quirk Factor. The main reason for this was that Nezu wanted to compare Izuku's Quirk Factor samples with Mordred's Quirk Factor sample. There were basically three samples Nezu ended up analyzing. The first was taken when Izuku was four. It wasn't that hard for Nezu to hack the hospital records to find the analysis of that sample. As far as Nezu could tell, it was basically a normal, inactive Quirk Factor, very similar to most cases of Quirkless individuals.
The second sample was taken from Izuku after he switched with Mordred at the end of that first week, and the last was taken from Mordred during that same week. What Nezu found was quite illuminating. Izuku's Quirk Factor was completely activated. You're probably wondering, what does that mean? Well, the best way to explain someone's Quirk Factor is to think of it like a tub of Legos. Every single person's Quirk Factor is made up of many different pieces, but only a few pieces are used to create a quirk just like a Lego set. Izuku, on the other hand, has all of them activated. His factor is literally just every Lego brick he owns smashed together into an amalgamation that doesn't do anything. Because his Quirk Factor does everything, it essentially cancels out any abilities he could develop, as everything wants to be used.
Think of it like standing in the middle of a stadium before a concert starts: everyone around you is talking, but it feels like being alone in silence because you can't make out anything anyone is saying. All their voices combine into a cacophony of silent noise. That was basically what was happening to Izuku's Quirk Factor. Everything wants to happen, so nothing happens.
However, when Nezu compared Mordred's sample to Izuku's, we get a different story. Instead of all aspects being active, only the normal amount—of the Quirk factor—is activated in Mordred's case. Nezu was interested in analyzing any alterations the Midoriya System might develop in the future. Maybe, if he collected more samples, he could discover how Izuku's Quirk Factor seems to turn specific parts off, depending on the alter or personality sitting in the driver's seat.
During the third week, Inko decided she wanted her son to try to go back to school. Izuku had become a happier person over the course of that week; getting to see heroes and hero students and being around all this positivity seemed to really repair the child's soul. However, Nezu knew better. By asking Izuku key questions, he discovered that Izuku's unknown gatekeeper alter was sealing away his worst traumas.
Even so, Nezu agreed. Both Mordred and Izuku had become aware of each other and were switching between the two, depending on the situation. In anything school-related, Izuku was upfront; during time to eat or fight, Mordred was in control. But even then, Nezu could think of many reasons not to send them back to Aldera Elementary. Aizawa had been investigating the school for a while, but for the most part, it just seemed to be the common place of Quirk-based prejudice reality they all lived in.
Yet, Nezu was also curious. He knew it was a mistake; he shouldn't have let it happen, but he was just so darn curious. He really wanted to figure out if Izuku had more alters, and the best way to find this out was to put him in a stressful situation."
So, Nezu relented and let Inko take Izuku back to school. It ended exactly as he had wanted and feared it would. Knowing it would likely end badly, he sent Eraser Head to watch over the school.
For the most part, things went pretty normally—well, as normal as it could be for someone who was clearly an outcast. Aizawa was pretty pissed when he returned to report after the day ended and the incident occurred. Ah yes, the incident happened when Izuku was leaving the school to head home. A gang of children, the school's resident bullies, followed Izuku and shoved him into an alley.
Before Eraser Head could do anything, six of the delinquents, clearly goons, ran out of the alley, screaming about a 'Knife Monster.' When he arrived, Aizawa discovered the ringleader (cough, cough Katsuki) of the little gang pinned to the wall by kitchen knives. None of the knives had touched his body; they were all stabbing into his clothes.
Across from the child was a new alter to add to the list. This alter had almost Coal black skin, white hair, and golden eyes. He stared at Aizawa with the most analytical look possible. When Eraser Head asked who he was, the alter responded in the most mechanical tone he had ever heard. He was, for the most part, a robot—an emotionless mechanical mind.
Mechanical alters were a well-documented phenomenon. The alter told Aizawa that they had no name. However, I decided to award this clearly defensive and combat-oriented entity with a designation that I believe fits him best: a name that means "palace guard." A true warrior created to defend the mind of a child.
The concept of a mind palace is well-known and intriguing, and the guardian of a palace of the mind deserves a name that describes them entirely. Their name shall be Emyia.
After that, Nezu convinced Inko to homeschool the Midoriya system—by allowing him to teach Izuku and the other Alters, of course. He believed they would be the most interesting students yet, and he delighted in the opportunity to analyze the knowledge transference between the three Alters. If he taught Izuku how to do multiplication, would Mordred and Emyia also learn? Would a mind like Emyia's process information differently than a Knight like Mordred? These posed fascinating experiments—uh, I mean, observations—to better the child's life.
Now, it's the fourth week, and Izuku and Mordred have become aware of Emyia. Nezu theorized that after the second emergence of an alter/personality, the ability for the others to become aware of this new alter is realized. The three of them could converse without leaving notes for each other, but they could all feel nudges directed at one another, according to my interviews with all three. Also, for anyone wondering, Emyia accepted Nezu's name suggestion.
After a while, Nezu finally obtained the results of Emyia's Quirk factor analysis. When compared to Mordred's, he guessed that each Alter would activate different parts of the Midoriya system's Quirk factor. Unlike Izuku's Quirk factor, which was fully activated, the other two alters had only the normal amount a human would have activated.
A human's Quirk typically represents only around 2% of their Quirk factor, and that percentage decreases with each generation of Quirked individuals. For instance, if you were a first-generation Quirked human, your Quirk would account for around 10% of your Quirk factor. It's a rather intriguing subject!
P.S. I'm kind of making this up as I go along. I have many ideas on how Quirks work, but since it's such a mysterious and often glossed-over topic, I have to innovate as I progress. Anyway, back to the fanfic!
Finally, Nezu managed to convince Mordred to allow Emyia into the training field to test his Quirk. At first, Emyia only created kitchen knives, but over time, more diverse weapons emerged. After recording Emyia's impressive displays, Nezu and Inko sat down to discuss the origins of these weapons.
Inko had noticed that the knives Emyia used at the beginning of the tests—er, I mean, training—came from her kitchen. Intrigued, Nezu slowed down the footage, meticulously identifying each weapon produced by Emyia: Spike Knight's sword, Eraser Head's utility knife, King Samurai's yari (a type of spear), along with a variety of other assorted weapons and kitchen items. However, they all shared one commonality—they all featured a blade.
Curious about Emyia's capabilities, Nezu asked if he could create any weapons on his own without relying on visual references. Emyia's response was negative; his a mind of steel lacked the creativity to innovate. It could only mimic what it had already seen.
The three alters each had their unique preferences and interests. Izuku favored quiet places and enjoyed reading, which made him quite antisocial. In stark contrast, Mordred thrived in lively environments. She loved loud music, engaging in fights, devouring more food than one would think possible, and adoring cute animals—essentially, she embodied the spirit of a typical tomboy.
As for Emyia, he seemed indifferent to most things, but there was one passion he had that stood out. Everyone unanimously agreed that he had a remarkable talent for cooking. Even Lunch Rush, known for his high-grade cooking skills and Quirk, was no match for the six-year-old culinary prodigy. Emyia's cooking prowess was undeniable.
From that day forward, Emyia became Nezu's personal chef, along with anyone else who could persuade him to whip up a meal. Fortunately, getting him to cook wasn't challenging; all it took was a simple request.
Nezu decided to postpone naming the Quirks of the three alters. While most children were quick to name their abilities shortly after discovering them, Nezu was more meticulous than the average Quirk doctor. Instead of formal names, he recorded placeholder titles in the Quirk Registry.
For Izuku, he noted "Unknown" with the remark, "We have no idea what this Quirk does." For Mordred, he assigned "Crimson Lightning," describing her ability to enhance and shoot red lightning. Lastly, Emyia's entry read "Blade Printer," detailing his capacity to replicate any bladed weapon he had ever seen.
Nezu was cautious about sharing too much information with the Hero Public Safety Commission (H.P.S.C.), opting to list the alters as three distinct individuals rather than one entity. He hoped that nothing would traumatize the system before they reached UA, allowing them to navigate their journey without complications.
Well, that's all folks hope to enjoy this chapter. It's a little longer than the First two chapters because yesterday's chapter was shorter and I just had a lot to write today. I hope you enjoyed.
Can you guys think of cool names for the Quirks Of Mordred and Emiya. I want unlimited Blade works to be Emyia's Quirk evolution so I want an MHA type Quirk name for his ability. And for Mordred should I stick with Crimson lightning? Or can anyone think of a cooler name for it? Anyway, thanks for reading bye-bye now.
