(This idea is based off of the animation called Undertale DDD, where Sans and Yukari Yakumo from Touhou Project crossed over. So, I figured why not make an Alphatale-like version of Yukari Yakumo to make this interesting. Plus, both Undertale and Touhou are indie games. Finally, the Alphaverse she'll go to takes place in an alternate FGoD Multiverse.)

My, how interesting is this all going to come soon in the realms~.-Equilibrium!Yukari

Equilibrium!Yukari is a version of Yukari Yakumo that exists in a version of the Touhou Projectverse called the Alpha Project. She is an extremely powerful Yokai and one of the strongest, with her strength growing even more then before when she has a special surprise within her very souls.

Backstory:

During the events of Fate Seeker, after being killed by Faker, Error404 has lost almost all its power, including the soul of the Conduit of Balance. However, Infected asked Nexus to reconstruct the soul by Cosmic Essence, and Bio Conduit, that is, the power of the Conduit, was artificially created by Nexus, and although Error404 is artificial, it is weaker than normal Conduit , Get the power of a new "truth conduit". And it's more powerful than before by giving NullVoid by Nexus, that is, a code for a place deeper than Mainflame. Also, reality can be distorted by the power of the guru, Alpha! Sans and Omnipotent! The great tsunami that occurred during the battle training of Sans is being erased by rewriting the reality. In addition, the ability has improved considerably, such as throwing a Faker with Blue Mastery. And he recaptured the soul of the master of balance from Faker and regained his power again. However, due to the second wave of the cycle reset at that time, he lost the soul of the Conduit of Balance and died again.

However, this would not be the end of the Conduit of Balance. Within another Eden Orb, there exists an existence that is different from Undertale, yet has a connection with it. It is called the Touhouverse, and this version of the Touhouverse is the first alternate version of it called the Alpha Project, with the species called the Yokai now being stronger then before. And when the Conduit Soul of Balance found a worthy vessel...it found it in an entity named Yukari Yakumo.

Within Yukari Yakumo, from the very second thar she was born, she was given great power unlike any other, and as she grows up, Yukari is shown to be able to become one of the strongest, if not the single strongest Yokai in all of existence, and during her years of growing, when she was 6,600 years old, her reincarnation, Error404, spoke inside of her mind and told her of her powers as a Conduit, and Yukari Yakumo began to practice with her powers, and trying the best that she could to master it. It took quite a long time, but as her powers are fit for her Conduit Soul, she was soon able to reach the middle of her mastery as a Conduit, being at Competent Level, but does still manipulate people to do some task for her. But overall, her life is still the same, or rather, similar to the original Yukari, in which she made Ran Yakumo, who then owns Chen. She even learns of the MainFrame, a reality above the Multiverses, and the fact that she somehow has a connection to it sense her birth, due to the Conduit Soul of Balance having a connection with it, thanks to what Error404 had done from before.

However, this all changed with Prism, the Forbidden Conduit of Disorder came, and the both of them speak to one another, before Prism revealed the truth about the Conduits, and wishes to bring her all around the planes of existence to show her, as he can sense Error404 inside of her. Although Yukari Yakumo isn't a entirely sure of doing this, she decides to take the chance and get to know what she is up against, and thus took his hand and went all over, but little did she know...that she will be in for a doozy.

Appearance:

Equilibrium!Yukari resembles that or her original self, but with some key differences. Balance!Yukari is a Youkai with the appearance of a young woman with long blonde hair and purple eyes who carries a parasol as well as a paper fan.

However, there are key differences between her and the original Yukari. Her eyes have blue pupils instead of the usual black pupils, and she also wears a purple dress with semi-detached puffy sleeves, as well as the collar of the dress spread and exposing a bit her cleavage. The dress reaches down to her ankles, where she is shown to be barefoot, and the picture of a Blue Dragon is shown to be shown on her dress, as well as white thin gloves that reaches just above the elbows. The purple dress also has a hood that can cover her head and make a shadow on her face, which makes seeing her face to be rather difficulty. Lastly, her blond hair is shown to be much longer then her counterpart, reaching down to a length that is in between her knees and her ankles.

Personality:

Befitting her original counterpart, Equilibrium!Yukari is known for being a very youkai-like youkai who sleeps all day and lives for the enjoyment of life. Though she rarely leaves her house, she's well-connected and is acquainted with most of the most powerful youkai as well as anyone having anything to do with the Great Hakurei Barrier or the outside world, although she rarely attacks humans. She has a tendency to toy with her opponents rather than use her full power from the start. If anyone is suited for the role of "mastermind", it's Yukari. She excels at mathematics and is experienced due to her long life.

She possesses superhuman intellect and especially surpasses in dealing with numbers, and as mentioned by one of her friends, even she cannot match this sort of intellect from Yukari. to the extent that for example that she is able to determine the depths of the darkness of Avici or determine in an instant how long it would take for Ursa Major to devour the North Star, as it seems. Concretely to what extent this amazing intellect goes is hard to know, but it would be no mistake to think that this intellect far surpasses that of humans.

She often has a great deal of insight and understanding about whatever happens in Gensokyo, and possesses considerable intellectual prowess, as well. Though she seems flaky and unreliable most of the time, when the safety or security of Gensokyo is at stake, she won't hesitate to get involved, even if it means using others to do the work for her. Yukari deals with problems by manipulating others to act to resolve things for her. She seems to rarely act directly except in particularly egregious situations. In all cases, she rarely lets anyone know what her true aims or goals are and sometimes these goals are extremely abstract, and at times is fickle, whimsical and lying often.

But with the Conduit Soul of Balance and possessing the knowledge of her past lives, and Error404, Yukari's knowledge and ability to manipulate people has become much more dangerous then ever before, and even gained some of his personality traits. The slightest grudge, she'll take the most exaggerated response. A permanent solution to a temporary problem. She now can always dominate the situation anytime she's present in, always knowing what to say and always being the one on top. Yukari, like Error404, has a complete god complex, yet she truly isn't a bad person.

She also inherited his sociopathy, yet despite that, she maintains a calm mind and still maintains a pleasant demeanor due to never going through what Error404 has gone through, thus she has perfected the capabilities to control her emotions, as even when she is enraged, she will not drop her affable and soft spoken nature, which will make people that talk to her very unnerved, as a cold chill being felt will mean that Yukari is extremely enraged.

Powers:

Shadow Gaps: One of Yukari's main powers, they act as portals between two places, where she's able to hold, sit on or emerge from such gaps. Because of this, she's able to show up at any place and can freely travel to places like the Outside World, and even can be used to travel to different Eden Orbs, especially the one that the Alphatale Brothers reside in.

Mental Manipulation: Yukari can take complete control of others' souls, allowing for her to alter, distort and warp their mind to think various things, commonly using this method to force others into serving her.

Boundary Manipulation: Yukari's main ability is manipulating any kind of boundaries. This ability has been described as logically being able to affect essentially anything. this power allows her to control or remove the boundaries between any and all things, like Gensokyo and the Outside World, the worlds of the living and the dead, humans and youkai and even the day and the night. This power can even affect an AU or a Multiverse. Ultimately, manipulating boundaries is described as a terrifying god-like ability with no weak points which there is no defense or countermeasure against, capable of fundamentally undermining reality itself and as one of the most dangerous abilities that youkai are known to possess, as everything is built upon the existence of boundaries; if there were no boundaries everything would effectively exist as a single enormous object. Because of this, the ability to manipulate boundaries is logically an ability of both creation and destruction: by making a new boundary is to create a new existence, and to destroy a boundary is to negate an existence.

Incredible Knowledge: Yukari is an extremely intelligent Yokai, possesses knowledge that almost no other Yukari can match with an exceptional few. Channeling her Conduit Soul of Balance allows her to know of her past lives, and she gains even greater intelligence then before.

Yokai Ray: Due to channeling her Conduit Soul, and hearing the voice of 404's instructions, she is able to learn her own God Ray technique called Yokai Ray. At the first shot, it is able to paralyze a person and cause them unexplained pain, or she can use to to destroy someone, and can even cause 12 AUs to be destroyed at the same time.

Spirit Whip: Yukari Yakumo is able to develop her own version of the Glitch Whip, with the range and power being much longer then Error404's. Unlike Error404, she is able to use this power when she is outside of the MainFrame.

Unchallenged Strength: Yukari has gained immense strength from the Conduit Soul of Balance, as it still possesses a connection to then MainFrame thanks to Error404, and thus, is actually physically stronger then Error404 himself, and even overpowered him once in a fight that they both had against one another.

MFTL+ Speed - Infinite Speed: Yukari has speeds so fast she can reach the center of universe in a matter of seconds to her showing feats of Infinite speed as shown with her traveling a Infinite universe in minutes. She is so fast that she is able to surpass Error404 in terms of sheer speed, doing it faster then Error404's own.

Incredible Durability: Yukari Yakumo is shown to possess far greater durability then even that of Error404 himself, being able to rank many hits and is able to keep on going with just very little injury and pain, with not even a bruise being present there.

MainFrame Shikigami: The manipulation of Shikigami could be considered another of Yukari's special abilities. Resembling the computer programming of the outside world, the Shiki will carry out its master's order exactly as commanded. Her high intelligence, particularly with regard to manipulating numbers, makes her excel at calculations and analysis. And as the MainFrame is entirely code-based, this power has increased even more then before, now allowing her to manipulate pixels and create anything of her own design.

Flight: Yukari is able to fly.

Dark Fantasy Manji-Parasol: Yukari focuses her spiritual energy into the form of a manji and fires it forwards, which destroys anyone that gets in the middle of its fire.

Bewildering Deocy: Yukari opens up a gap that fires random projectiles at high speeds, with each projectile being random in damage, but even the lowest damage is extremely painful. They are stronger then the Anti-Void Bones.

Eyes that Demand Balance: Yukari opens up a gap, in which an eye glares at her opponent, firing danmaku at her enemy. She can open up several of these gaps at once to attack at different points in time, such as when an opponent moves or whenever an opening presents itself. This power is a lot more powerful then the Dark Blasters, and can destroy multiple AUs at once, and even a couple of multiverse at the same time if enough is brought in. It has an additional power in that it can attack ghostly enemies. She can also use a variant of this attack called Mystic Sight "Laplace's Devil", in which Yukari opens up many gaps, all with eyes glaring out at her opponents, firing projectiles whenever an opponent presents an opportunity, and cause an explosion, even destroying a Multiverse on one occasion. This is apparently how Yukari stays aware of what is happening in the Multiverse.

Yokai's Fear: Yukari inherited her previous incarnation's abilities of instilling fear into any being that holds a soul. But she only does this whenever she is enraged.

Reincarnation: Yukari is able to come back to life if she were to die, and can even use bits and pieces of AUs in order to quicken her healing.

Void Infliction: This ability is an automatic, only caused from Yukari entering a void. Upon her entering a void that isn't an anti-void and/or the Mainframe, the amounts of stray data in the area will begin to rapidly vibrate, rumbling and possibly even collapsing the void.

The Yakumo Express: Yukari will summon a train out of a gap from complete nowhere and uses it to ram into an opponent, hurting even Error404 with it by ramming him with it.

Yokai Multiverse: An extremely dangerous power that Yukari has, she can make a small orb appear in your hand, expand it instantly, and take your opponent into the "Yokai multiverse" of Yukari. This Yokai multiverse is a large-scale multiverse composed of a sea of codes and a large number of multiverses, and the large number of orbs that clung to the opponent's body and obstructed movement were all multiverse itself. More than billions of numbers and code letters are floating in the air. Yukari destroys using the God Ray by releasing them into those orbs, firing billions of orbs, and even make entities resembling Ran Yakumo and Chen to attack the opponent. Adding to the dangers, the eyes from the Gap are also present, appearing in the sky, as they shoot down attacks from above in order to kill the opponent trapped. In this area, Yukari can do whatever he wants inside of the Multiverse thar she makes.

Shikigami Operation: A power that Yukari developed, in which she can use it speed up her natural healing, or use this power to overload a person with Shikigami, destroying them.

Shikigami Hell: This technique takes out and reproduces all the negative things such as the opponent's trauma, the worst anxiety, shortcomings, mistakes, regrets, etc., and times the pain by 1,200 times. You can't move, can't go anywhere, and you're literally hung in the air in the worst nightmare.

Transformations:

B.U.T.T.E.R.F.L.Y: Due to the Conduit Soul of Balance's connection to the MainFrame, Yukari Yakumo gains access to the B.U.T.T.E.R.F.L.Y form as well, just as Error404 had done. Unlike 404, who initially had a hard time controlling it, Yukari was able to control it much more easily than him, to the point that she can activate this power on her own. This major power boost allows Yukari to destroy anything in her path and gives her full control of existence itself ranging to many of the Hyperverses within Reality 6, although not all of it.  This form can kill some with just a mere touch similar to that of a death's touch and can fly at such high speeds that instant teleportation is what it takes to match Butterfly. It's attack potency allows it to break apart and distort an entire Hyperverse just by moving.

Ultranova: A high-powered laser that can be emitted from a pattern like the eyes of its own wings. This laser has infinite superiority over large-scale cosmic energies such as supernova explosions. Anyone who hits this laser is given a huge crack in existence itself.

JUST!YUKARI: As this name suggests, this is the Malware-Controlled form of Yukari Yakumo. Mindless, Soulless, and Codeless entity which applies the same things to Yukari when hosting him thus making any code, soul or even mind powers completely useless. Just!Yukari is both a form as well as a different mindset, the form happens due to Malware, as stated before, hosting her and lending him some power as well as gaining a few of Malware's abilities if Malware is generous enough to give them or if he actually needs to give them.

Eyes that Bring Decay: Just!Yukari opens up a gap, and the eyes that are corrupted by the TransVoid Being glares at the enemy, before firing a corrupted Danmaku without warning, with the Danmaku capable or causing decay and rotting of death to those that are hit by the attack. It is so strong that one single Danmaku can cause an entire Multiverse to decay in just a few minutes.

Yokai Eyes: Just!Yukari can fire an attack similar to the God Eyes, in which can fire from the eyes and can track and follow Just!Yukari's targets anywhere so long as she can see them, once they hit the target both soul and the code of the individual are destroyed and erased completely.

Eyes of the Oni: Gazing into Yukari's eyes for at least 3 seconds would send the most sane of people into a deep, deep fear that they could be paralysed by the very sight itself. It would even disturb the likes of Infected.

JUST!YUKARI B.U.T.T.E.R.F.L.Y: Just!Yukari B.U.T.T.E.R.F.L.Y is a perfected, yet corrupted version of the B.U.T.T.E.R.F.L.Y form. By tapping into the infinite power of the MainFrame and into the near-limitless power of Malware, Just!Yukari B.U.T.T.E.R.F.L.Y became the ultimate embodiment of pure uncontainable chaos, capable of feats that Yukari herself could not do.

Time n Space control: Just!Yukari B.U.T.T.E.R.F.L.Y can manipulate Time n Space around her, slowing down some things to a complete stand still or even being able to shatter whole parts of space itself. It is also able to mess with the concept of time within Reality 6, to where she can slow things down to a almost standstill like movement where characters believe their reaching him when in reality they couldn't be none the wiser.

instantaneous movement: Just!Yukari B.U.T.T.E.R.F.L.Y moves so fast that it appears where it wants to be instantly, almost sometimes so fast it can appear to be in two places at once to some people.

Omninova: Just!Yukari B.U.T.T.E.R.F.L.Y's most powerful attack. The technique called Omninova used in this form can be created by absorbing the energy of reality with nine wings. And it takes a total of 17 wings to retain that energy. This sphere takes time to launch, but during that time, the magic and power increase exponentially. When released, it becomes shaped like a sphere the size of a large
