|Yami Sato|

Satō Yami: 彌海 (Yami) - "ancient" (彌) + "sea" (海). 佐藤 (Satō) - 佐 (sa) has meanings related to "help," "assistance," or "service." 藤 (fuji) means "wisteria" (an ornamental flowering plant). Full name: 佐藤彌海.

A few days later, Miyu finally accepted Yuki and decided to let her fall in love with Yami. She became convinced that Yuki was a kind and good girl. To Yuki's surprise, Miyu uttered only one word: "Mom!" Yami wasn't surprised, as he had expected this answer, and simply remained silent, allowing the moment to unfold.

Yuki was shocked to hear Miyu call her her "mother." For a moment, she was taken aback and couldn't believe her eyes. Miyu also said she wanted to be an "adopted daughter" for Yami and Yuki. She dreamed of having a father like Yami and a mother like Yuki. Yuki, blushing and looking down, quietly but confidently agreed to be Miyu's mother. Black tears began to flow from Miyu's eyes, and the streaks from Yami's eyes began to bubble, reflecting Miyu's emotional state.

Yami, thanks to Miyu, also possesses deadly poison in his claws. Each attack or cut leaves deep wounds in the victim's body, which passively absorb this poison. The poison begins to slowly spread throughout the body, causing serious consequences.

Yami is willing to cross the line and take someone's life, having had similar experience before. He resorts to violence without hesitation when necessary, knowing he will gain nothing from it. However, Yami is not an absolute monster: he will not kill without reason and will not harm the innocent. His actions are directed solely against those who deserve it.

After committing murder, Yami feels no emotion.

Yami has never been a hero or performed heroic deeds. Perhaps he did display heroism in the past, when he was known as En, but that was so long ago that he no longer remembers. What he was like back then doesn't matter to him, and he has no desire to remember it. Now, his main goal is to live as an ordinary person, not as some great hero... of this world.

Yami and Miyu's relationship isn't romantic. Miyu is still a child, and Yami understands this. He treats her like a daughter or a sister. His care is expressed through a friendly silence and support for her desires. Yami is always interested in her interests, trying to better understand her needs.

He never scolds her, preferring to communicate gently and warmly. Yami understands that Miyu has had a difficult past.

When Yami and Miyu's souls merged, but not completely, Yami's eyes began to darken, turning into impenetrable blackness with red irises. Black tears began to flow from his eyes, stopping at the level of his chin.

These black tears were the result of Miyu's intense emotions. When she began to experience deep feelings, they were transmitted to Yami, and similar tears began to flow from his eyes.

Over time, their souls finally merged, forming a single whole that could no longer be separated.

As for Yami's blood, it was now completely mixed with Miyu's black blood. His body had been significantly altered by the influence of Miyu's demonic essence.

Yami could instantly transform into a woman with a simple snap of his fingers. The process required no fanfare or flourish; it was quick and simple.

When Yami was En, he became a woman for the first time. Sometimes he was transformed into a girl, but Yami can't remember who did it—too much time has passed.

Having become Andrew, he began to independently but actively transform into a girl according to his desires.

Even today, he is capable of becoming a girl at will.

As the plot and story changed shape, Yami's family changed as well.

In the early versions, when he was known as En, he had a mom and dad, but their names were not given.

Then he found a new family: Nastya (the future Kiyomi) became his sister, and David (the future Katsu) his brother. Mom and Dad remained in the background.

Later, the plot changed again, and he was left with only friends: Nastya (future Kiyomi), Dani (former David/future Katsu), and Anna (future Yumi). Over time, their friendship grew into a semblance of family.

When the plot underwent further changes, En's name was changed to Andrew, and his family became complete. It included Nastya (future Kiyomi, the older sister), Sonny (future Mizuki, the younger sister), Dave (future Ken, the father), and Katie (future Miyuki, the mother).

In the latest and current storyline, he's become Yami (formerly N/Andrew), and his family has expanded even further. He now has a younger sister, Rin, a mother, Miyuki, and a father, Ken, along with numerous other relatives.

Annie is Yami's female incarnation. She appeared in the old storyline, when Yami was still Andrew. At that time, he had a second soul, but it was Annie, not Miyu.

Annie isn't a demon, but his female alter ego. Annie's peculiarity was that when Yami (formerly Andrew) disappeared, Annie would take his place, as if she had a second life, albeit one different from her first. This was because Annie didn't have a soul of her own, only determination, like Yami.

In the new plot, when Andrew became Yami, Annie disappeared and was replaced by Miyu. However, the essence remained the same: Yami still has a second soul, although now it's Miyu, not Annie.

Yami has a white bracelet that contains references to characters' abilities from other shows. This bracelet contains the powers of "Sans," "Ryōmen Sukuna," "Gojō Satoru," "KJ," and others.

However, Yami rarely resorts to his help. In the new storyline, he barely uses the bracelet, preferring to rely on his own powers. The bracelet no longer plays a key role in his life.

The bracelet appeared in the story when N/Andrew transformed into Yami Sato. It symbolizes the past, when Yami was N and possessed only the abilities of others. Furthermore, the bracelet serves as a meta-reference to other projects, such as "JJK," "Undertale," "Solo Leveling," "Chainsaw Man," and others.

The bracelet currently resides in the Sub-Void, where Yami keeps it. He has never taken it out, except once, when he wanted to remember the beginning of his story.

1. "Have you ever wondered why you live at all if you are just one of many pieces in a giant chess game?"

2. "In a sense, I'm part of a larger mechanism. Each part has its role and purpose, and I perform my function, ensuring the entire mechanism works. But what if this part breaks down? Its malfunction could cause the entire mechanism to fail, and then everything would stop. I am precisely that part that has failed."

3. "I sometimes pretended to feel real emotions for the sake of the plot, as if I were an integral part of it. But I got bored with it, because inside, I'm still empty. No matter how many roles I tried on in different stories, the emptiness inside me never went away. So don't be surprised if I seem gloomy to you."

Yami, he is like an older brother to all the characters and like a father to them.
Yumi is like an older sister to all the characters and like a mother to them.

So, in fact, you can safely call them daddy and mommy, but if you talk to Yami, you don’t need to with Yumi, she is more daring and hot-tempered, and hates when she is called mommy, but deep down Yumi is a vulnerable girl, since in the new storyline her mother died at the hands of a person, and now she hates all people, thinking that everyone is the same, but Yumi still, although she hates Yami, she calls him “Yami-sama”.

Yami remembers everything significantly, even his past and what he was like then.
He especially knows that he was simply a generic character with limitless power, who didn't have his own plot, but at least he had a girlfriend, Anna, technically Yumi. It's just that in the old plot, her name was Anna, and his was En. Yeah, not particularly effective names, but he knows the author tried and was always refining, removing, adding, then removing or reworking, and then, when the time came, his name became Andrew, and he acquired his own abilities. Although they weren't effective, at least it was something different from mere strangers. Yumi, aka Yami's girlfriend, always remained and they always developed alongside him. Well, half the other characters remained as well, but they were either reworked so much that they're barely recognizable, or were removed, or something else. And then he finally had some kind of family, with Sonny, technically Mizuki Kiri, and Nastya, technically Kiyomi Kiri—who were his sisters back then, and his father, Dave, and his mother, Katie, who is now technically Miyuki Sato. And in this story, as it developed and was reworked, at least some kind of plot emerged, albeit a weak one. And when enough time had passed, his name had become Yami Sato, and his family had also changed: he now had a younger sister, Rin Sato, a beloved mother, Miyuki Sato, and a beloved father, Ken Sato. His friends remained: Katsu Ibuki, technically Dani, Yumi Mizuno, technically Anna, and Kiyomi Kiri, who is technically Nastya. Well, a new character and friend appeared, although an old character, because she was made a long time ago, but was not added in those stories, this is Yuki Hasegawa, who is very devoted and adores Yami Sato, she is crazy about him, although she is very shy and afraid to admit it, but she is a damn beautiful and sweet girl.

So technically, if you put the old plot and the new one together, then Yami and Yumi are older than all those who are new characters, but those characters who were also in the old plot, it’s debatable, but still, Yami and Yumi are older.

How are his relationships with girls? Yami gets along well with them and even helps them out sometimes if they ask. He also noticed that girls looked at him with particular interest. Yami understood that they were in love with him, but he didn't pay any attention to it and continued to move forward, unfazed by their attraction to his appearance and personality.

Yami still deeply loves Yumi, but he, as a mature man, has let her go. He has a system for rewriting, deleting, and creating, but he doesn't use it. Yami doesn't want to hurt Yumi, as he let her go long ago with kindness, not malice. He doesn't want to bring back the Yumi who loved him (not because he doesn't want to, but because he strives to keep her as she is). Yami values ​​her for her lively, cheerful, and daring nature. For the first time, he genuinely smiled when he looked at her. Yami wants to keep her like this, not allowing her to suffer from meta-knowledge as he once did. Despite this, he still loves Yumi and is willing to make the world a happier place for her, changing it for the better.

Ayumi also evokes warm feelings in him, as she became his new girlfriend in the new storyline (for a meta-character, it's a new girlfriend). However, his present self didn't take her death in the accident too seriously, while his past self mourned it deeply. This isn't because he's evil, but because he's had to deal with so many deaths. Nevertheless, he continues to love Ayumi sincerely, even though she's gone. She helped him realize something important, and he will always cherish that realization as both a shield and a weapon.

Yuki had always been in love with him, and he knew it. He also knew of her desire to become his apprentice, but he tried to keep a low profile, lest he reveal his meta nature. Yami decided to become an ordinary person for her sake and forget everything else. Though he tried not to show it, he sometimes did things that Yuki, being too shy, couldn't ask him to do directly.

He deliberately got too close to Yuki, but he did it in a way that made it look like he was just helping her with martial arts or everyday life. He knew she liked it, so he continued to do so, trying to remain unnoticed.

Katsu, Yumi and Kiyomi have always been his friends, even in the old storyline, although it’s hard to call them friends, since they have been that for so long that they have already become an artificial family.

Yami (formerly En/Andrew) was like - Father;
Yumi (former Anna) was like - Mommy;
Kiyomi (former Nastya) was like - The eldest daughter;
Katsu (formerly David/Dani) was like the youngest son.

But despite the fact that they had been friends for a long time, at the very beginning of the plot they were not there, there were only Yami (former En/Andrew) and Yumi (former Anna), they appeared even earlier, in 2023/2024 real year, when the author just started creating.

Katsu Ibuki are good, but because Katsu forgot about Yami, they are already average.
Yumi Mizuno - lovers, but also because Yumi forgot about Yami, they are already bad.
Kiyomi Kiri is good because she's also become a meta character on par with Yami, and Kiyomi still remembers Yami, even though we're all in the new storyline. In the old storyline, Kiyomi was once an older sister to Yami, but things are different now, and yes, Yami is still older than Kiyomi, since Yami appeared even earlier.
Mizuki Kiri is good, but she also forgot Yami and doesn't remember him, but once upon a time in the old story, she was Yami's younger sister.
Yuki Hasegawa - Romantic relationship, as Yami found a new girlfriend, and it was Yuki, who was deeply in love with Yami and was crazy about him.
Ken Sato - good relationship.
Miyuki Sato - good relationship.
Rin Sato - good relationship.
Stella Nova (now Error!404) - good relationship.
Alternate Yami (Chief Killer) - Partial ally.
Rinko Yukimori (FATAL ERROR) - average relationship.
Ammi - bad relationship.
Yoko Hino is good and she's also a meta character.
Hana Sakurai - good relationship.
Nao Binary (V-Error707) - good relationship.
Miyu Suzuki - good relationship.

Most of the time, his main soul (Determination) dominates everyone and even dominates Miyu's soul (Hatred).

Yami is inhabited by the spirit of a demoness. She sometimes manifests on either side of Yami. Thanks to her, Yami's strength has partially increased.

Yami's Soul: Heart-shaped, red (Determination).
Soul of the Demoness: Heart-shaped, black (Hatred).

Together: Red soul, and inside in the middle is a black soul.

Yami can change the length of his claws at will (this was made possible by Miyu).

In the past: the cut and ultra-cut appeared thanks to the demoness.
Currently: Miyu has two techniques, Yami inherited "Dismantle" and "Disassemble".

Miyu, by the way, wasn't always a demon. In the past, she was an ordinary girl who was often bullied at school.
Yami has become familiar with Miyu's history and is now knowledgeable about her.

Miyu is Yami's trusted companion. Their bond can be compared to the relationship between the Earth and the Moon.

When the second phase ends and deactivates, Yami will be exhausted, making him more vulnerable, but not critically so. His mana remains at 40%, allowing him to at least briefly defend himself. The demonic horns, wings, and tail are removed, the black substance that replaced the blood is also removed, and normal blood returns. His pupils and irises also return.

When Yami is critically wounded, the "second phase" is activated.

In the second phase:
First, demonic horns appear, then demonic wings, and then a demonic tail. The pupils and irises disappear, and the eyes become black/empty.

Traits: At the wound, blood begins to turn into a black substance, preventing real blood from flowing out. But sometimes even the substance leaks out a little, whether during battle or not.

The demoness (Miyu) called this phase "Blood Contract - Shackles Released".

When Yami changed and became different, Yami learned to control this second phase, that he even learned to activate it on his own, but even so, he is not capable of it without Miyu’s help, since Miyu knows how to stop the blood with the help of a black substance.

In the second phase, Yami remains 100% himself, so Yami has learned to control this phase and is no longer able to become a monster.

In the second phase, Yami's strength and speed are increased by 5x. However, there's a catch: the demoness can increase Yami's strength and speed. However, the demoness will begin to tire, but not as much as before. Once she tires, the "second phase" will automatically end, without any set time. Yami's blood will return to normal.

There is time to turn off the “second phase”: 30 minutes.

System:
Yami is the only meta-character in his world who is directly connected to the system (if you don't count Stella, bugs, and viruses). But Yami isn't a novice, he's an expert, and he knows how to control it, but he doesn't consciously want to, instead trying to do everything himself with his own strength and perseverance. Just like in the games, Yami can gain experience and improve his stats (which Yami never actually did, but achieved to this level entirely on his own). And after several years, Yami has officially become the master of his system and doesn't consider it just a weapon, but something more.

Guardians of the Multiverse:
Yami also met various guardians, who, surprisingly, were nice and happy to welcome guests. But among them, he once met Stella, who had previously been normal and was also a protector of one of the multiverses. There, Yami and Stella first met and became friends, though ironically, the destroyer of worlds befriended the guardian of worlds.

Corrupted creatures:
Yami is also familiar with corrupted beings, or more precisely, they call themselves errors or viruses, and it was he who encountered FATAL ERROR and then VIRUS 404.

At his discretion, he can activate the system's red holographic window, which contains numerous different sections. Yami is also recognized as the administrator of his world, as confirmed by his role in the system: "Role: Administrator."

Metamorphosis: Red:
A medium-sized ball of energy forms at Yami's fingertips, pulsing with endless destructive power. This ball is capable of destroying entire squads of enemies or even the final boss.

The energy that Yami wields is unique: it can not only be used as a projectile, but also transformed into a powerful beam, also effective in combat.

Furthermore, this energy can take the form of bladed weapons. Yami prefers to create an elegant "energy knife" from it. He can form either one or two knives at once, depending on his preference.
Costs 0.5% of mana.
———
Disintegration of matter:
Using both hand seals, Yami can create a medium-sized red energy ball between his hands, pulsating with extreme, even massive, energy. When Yami launches this energy ball into the sky, it will begin to grow in size, becoming increasingly larger. Yami can especially control it with his mind.
After that, when Yami simply snaps her finger, the ball itself will simply explode, creating a powerful shock wave that is capable of destroying not only everything in its path, but also the entire world into atoms.
First of all, Yami needs to be focused and patient before such an attack, as it can easily destroy everything.
Costs 20% of mana.
———
Darkness: The mark of the curse:
Yami can manifest black, translucent flames on both of his hands, greatly increasing the physical power of his attacks. Using them, he can destroy a wall with a single blow or leave a dent in the asphalt. This ability costs no mana; it's completely free.

There's a more powerful version of this ability. Yami can select all worlds, objects, or beings at once, or just one. When he clenches his fist, everything selected is instantly reduced to atoms, leaving no trace. A mark of black, translucent flame appears on everything Yami selects.
Spend 30% of mana.
———
Dismantle:
Yami can use his claws to create various types of slashes in the air, which then move quickly towards the opponent and tear them apart.
10% of mana is spent.
———
Disassemble:
When Yami does a backflip, he simultaneously uses his claws to create slashes in the air, similar to a ball, which then rushes towards the enemy, tearing them apart.
The mana cost of this technique is still unknown.
———
Manipulation:
Yami's ability to control objects with his mind is unmatched. Yami can manipulate objects unexpectedly and attack unexpectedly, even without being detected, as no one even knows it's Yami himself. Yami can also control people or even body parts, and can even simply stop them for a second and then lower them. Yami can also manipulate ordinary objects, such as cars, sections of wall, debris, and so on.
———
Healing:
Miyu can also heal Yami with her black substance, but this healing only works on Yami's own body, not on others. Because Miyu is Yami's second soul and they have become linked, Miyu can easily heal Yami's wounds, and quickly at that, but critical wounds heal very slowly. So Miyu came up with a trick and decided to transform Yami's blood into a black substance to trap his blood and heal his wound. Although even this way, the substance can leak a little, and it will leak especially quickly during battle.
———
Vision of the plot:
Yami, as a meta-character, has the unique ability to see the entire plot at a deep level. He knows all the key events, the initial moments, and the final outcome of the story. Furthermore, Yami can temporarily foresee the intentions of other characters or easily predict an enemy's first attack.

Yami rises above the plot, standing outside of it. Remarkably, he has long since ceased to be human.
———
Teleportation:
Yami possesses a more advanced teleportation ability than others, thanks to years of training. Unlike Shortcut, which is limited in its capabilities, Teleportation has no limitations and allows travel over various distances, from short to infinite.
———
Gate Creation: Yami can also use his claws to tear the fabric of reality, opening portals to other worlds, the void, or even various multiverses. He can also easily close them when needed.
———
Unlimited Inventory: Yami also has an inventory like in the game, but due to his abnormality, his inventory is now unlimited, allowing him to store anything he wants. However, Yami also uses his Sub-Void to store all sorts of junk and items.
———
Sleeping pill:
When Yami gently and carefully runs his finger across a person's forehead, a soft red glow flashes on his finger for a moment, then fades. The person he touched immediately begins to drift off and falls into a deep sleep.

Yami had recently acquired this ability and decided to master it, hoping that it would be useful in the future.

Puppeteer: In two turns, Yami can control one opponent like a puppet, who will then start attacking their own forces. The Cooldown: 310s.

Passive Bond Skills
The Fate of Souls: When Yami and Miyu are simultaneously filled with determination, the “Permanent Effect” will grant +500% HP and 85% damage resistance. If both attack the same target simultaneously, there is a 5% chance of “Resonance,” which will grant 150% bonus to critical damage and apply the “Stun V” debuff to the opponent. “Price” — if Miyu or Yami gets distracted for a while, there's a 1% chance of taking lethal damage, and in addition, there's a 30% chance of getting the “Poison III” and “Slowness II” debuffs.
The theft of breath: When Yami or Miyu deals lethal damage to an opponent, “Borrowed Sigh” will restore 57% HP and Mana for Yami and Miyu. When Yami or Miyu gets into trouble, “Hidden Manifestation” will grant Yami or Miyu “invisibility” for 33 seconds.
Torment: “Constant effect” will allow Yami and Miyu to restore their total HP by 15 units upon taking damage from others. If Yami takes critical damage, there is a 50% chance that “General Wound” will grant Miyu a 200% increase in strength and movement speed, and with a 30% chance, she will automatically counterattack the offender.

Immeasurable Strength: His physical strength is so great that he is capable of cutting anyone to pieces, as well as easily destroying someone's defenses, no matter what they are made of, as if they were just fragile glass.

Immeasurable Speed: Yami's speed is so phenomenal that it transcends all conceivable limits, elevating the narrative to a new level. To ordinary people, Yami appears to instantly disappear from sight and just as quickly reappear in a new location, distancing himself from everyone present. Yami is capable of covering any distance in a single second—and I mean that in a single second.

Immeasurable Stamina: Also, no one saw Yami being tired, everyone saw that he was always cheerful and full of energy, although yes, there are moments when it was visible, especially when the second phase turned off, but even so, he always looked as if for him fatigue simply did not exist in his worldview.

Immeasurable Durability: Surprisingly, his resilience is truly astounding, allowing him to withstand any physical or magical attacks as if they were nothing more than dust beneath his feet. Even the most powerful blows, which sometimes reach Yami, leave only minor scratches. However, if he encounters an opponent possessing incredible strength, his defenses will be insufficient, and Yami will suffer critical damage.

Immortality: He became biologically immortal and stopped aging naturally.

Power Inheritance: When Miyu becomes Yami's second soul, he is able to inherit all of Miyu's cutting techniques, making them an extension of his will.

Immense Mana: After years of intense training, he has become more skilled at managing his mana and conserves it carefully for the finishing blow.

Combat Mastery: After several years, Yami became a master in martial arts and is also capable of combining complex techniques with light ones, as well as acrobatic movements in combat.

Indomitable Will: Despite all the events Yami has witnessed, and everything he's been through, and how much he's lost, how much pain he's felt, and how much it's all hurt. His resolve constantly burns in this darkness; it burns through the darkness, through the battles, through the plot, and also through the pain. He will always get up and fight, as if nothing happened. For Yami, giving up is a foreign concept; he's no longer the same person he once was, but for his family, for his friends, for his beautiful Yuki, he's ready to move forward.

Meta-intelligence: His intellectual abilities far exceed those of humans, going beyond our comprehension. He is able to grasp an entire plot by reading it in its entirety. Furthermore, he possesses a profound understanding of reality and recognizes the existence of an objective world. His mental abilities have increased exponentially.

Combat Intelligence: He also possesses exceptional intelligence and combat skills. Yami never enters a fight thoughtlessly and never lets his enemies get close. Before engaging, he carefully analyzes his opponent, identifying their weaknesses. In combat, Yami prefers dodging and retreating, avoiding head-on confrontations. While he does attack, he does so with limited force, preferring to wear down his enemies with cunning and agility. When the opportune moment arrives, Yami delivers a devastating blow.

Yami is a kind and serious guy who loves peace and his sister. He's become more distant than before, and even a little strict. But despite everything, Yami remains the same person he once was, deep down, while on the outside, he's a cold and stern senpai.

His mystery and strength do not prevent him from being kind and never offending others.

He also loves sweet and charming women. He even loves his girlfriends very much, especially Yumi (she was with him for a long time, but in the new storyline, she forgot him).

His knowledge has always been at the forefront; he is aware of everything, including the real world. His mind transcends logic and laws.

He also prefers strong alcohol and coffee.

Yami lost his former cheerfulness and became reserved. But his feelings for his younger sister, friends, and parents remained the same.

Yami can conceal his aura at will. He does so in his sister's presence, but not completely.
He tries not to argue with his sister so as not to upset her.

Yami has become a balanced and reserved person. He doesn't try to flaunt his power and doesn't care what others think of him. Sometimes, Yami is capable of performing a selfless act of kindness simply because he feels like it.

Yami shows himself to be a mature person and always acts like an adult, not like a child.

Short black hair, neatly combed back, with long bangs neatly combed to reveal part of his forehead. Attractive black eyes with red irises, from which a black substance flows down to his chin. A handsome face with a clean jawline. A slender, muscular build, with shapely legs. He's a sweet and attractive adult.

A white, minimalist jacket with a zipper, open at chest level, a gray fur collar on the shoulders, medium length, sleeves rolled up to the elbows; a black sweater, closed neck, long sleeves; black gloves with open fingers; black trousers with a belt; black boots.

Around her neck is a black choker; a decorative element on her right shoulder is a stylized small demonic wing with a buckle. She wears round sunglasses.

He rarely wears a zippered jacket with a gray fur hood to hide from others and not to frighten them with his appearance.

To avoid scaring people, he wears a black mask that covers his mouth and hides the black streaks from his eyes to his chin.

He also has a bunch of everyday looks that highlight his attractiveness, cuteness and hotness, which often made him notice that all the girls were staring at him.

When he's at home, he wears a black shirt with two buttons undone, casually tucked in, and the sleeves rolled up to the elbows. He also wears black pants and black socks. He also removes his stylized little demon wing with the buckle. He keeps his gloves and collar on, just because he likes it that way.

He sometimes wears round sunglasses, depending on his mood. He wears them outside so as not to alarm passersby. At home, he can wear them at his own discretion, as he likes them and they complement his look. Although he doesn't always wear them at home.

He also has another casual look:
He wears a black shirt with two buttons undone, and over the shirt he wears a white hoodie with a hood and pockets. He also wears black open-fingered gloves, black pants, and black lace-up boots.
