To some, Yuugi is a prophet – to others, a complete madman. But one thing is for certain – her control over the Underdeck of the Ultra Station is indomitable.

After allegedly seeing ‘the truth’ from her first experience with the nihiltoxin-derived street drug nihiline, Yuugi made her way from the surface of the Station to the Underdeck in order to chase the truth she’d seen.
The truth in question? To hear out and free the forsaken souls of those lost to the Ultra Deep Sea – and to take control of Lunaires in order to dissolve the barrier that held the inverted sea up.

While many thought she was completely crazy, her power was a force to be reckoned with – and soon enough, Yuugi was able to brute-force her way to the top of the Underdeck’s food chain. She quickly formed close bonds and joined forces with a strange hacker and deadpan occultist, and the three were unstoppable.

But… when it seemed that Yuugi’s final goal was finally in sight, her closest ally, Suika, started to have opposing plans… and didn’t seem keen on any kind of compromise.

But that family she’d made wasn’t a priority, at least that’s what she kept telling herself.
Just how much of a mess will the infighting of the Underdeck’s boss duo cause, and what will happen if Yuugi goes to desperate measures?


Appearance

Yuugi is 6’02”, with a muscular build. She has long, flowing pink hair, and light blue eyes – with a dark sclera. She has two curled ram-type horns, and long, pink ears with light blue patches. Her left arm has purplish swirled markings, due to frequent use of nihiline.

Per her species, Yuugi has a peculiar two lunar halos that matches the phase of the mark on her leg.

Personality

Yuugi is loud, brash, and confident with a massive ego – and she sees no reason to change. She prefers to trample over others with sheer force in order to get what she wants, and often gloats over her victories and enjoys making public displays of humiliating her enemies – and sometimes her subordinates as well. She doesn’t answer to anyone, and will laugh in your face if you attempt to tell her what to do.

Despite this, she likes to consider herself as relatively ‘spiritually in-tune’ – and is surprisingly skilled at practicing mindfulness – though she often imbibes with various substances in order to achieve a point of ‘transcendence’.


Story

Beginnings (0-30)

To Yuugi herself, much of her early life is lost amongst blurs of thought. It’s not something she particularly minds not being able to recall clearly, but it provides context into the type of person she’s become.

Yuugi never knew her parents, and grew up in a shared home for children whose parents left them there after birth. It was a well-maintained establishment, thanks in part to the high quality of living in the Ultra Station.

She was among some of the rowdier children, always seeming to be filled with an abundance of energy – but didn’t ever come across as a troublemaker.

Her performance is school was generally average, though she excelled in athletics – and was a particularly notable member of the combat sports club, having racked up a number of notable trophies by the time she graduated.

So, it was only natural that after graduation, Yuugi would continue on with this path. She quickly became indomitable in the pro combat sports scene as well, though came to loathe any attention she got from media.

It was alright, but it felt too… clean. Yuugi wasn’t able to utilize her ‘full potential’ without others getting hurt beyond what the sport would allow.

In a private setting, Yuugi vented this to a lower level of management – who made a one-off joke that Yuugi would ‘enjoy the underground scene’.

Unfortunately, Yuugi didn’t take it in jest.

She had no idea there was an ‘underground’ scene, so she did some looking into it… and found that something with no limits and higher rewards sounded just up her alley.

So, Yuugi left the world of professional, regulated combat sports behind – and became just as notable as a fighter in the extralegal counterpart.

Having never lost a match, Yuugi was able to create a comfortable life for herself doing something she enjoyed, even if that something happened to be beating people up until they were unconscious.

But as time went on, the scene began to change… revelations in science had led to new methods of doping that those in the underground scene would use, and a closer-than-normal shave and a broken nose left Yuugi wondering if she’d have to resort to it as well in order to maintain her position.

Upon hearing her complain, one of Yuugi’s top monetary supporters brought up something unusual: there was a new street drug going around after having been leaked from a top-secret government facility.

While it wasn’t a traditional means of doping, the drug – dubbed nihiline – was allegedly sourced from the mysterious and dangerous parasite known as nihilego, and had a strong dissociative effect. But what had the eye of the stakeholder was that they’d managed to accrue wild-sourced nihiline, as opposed to taken from the lab-bred population.

They seemed to think that, potentially, a trip would be able to allow Yuugi to extend her potential by ‘breaking her subconscious restraints’.

Yuugi thought this sounded a like a lot of nonsense, but after the last close match…

The truth and takeover (30-31)

Yuugi was never averse to substance use, but trying something new was always a bit unnerving… especially when it seemed as high-profile as the stakeholder described it to be.

Still, with a deep breath, Yuugi tried to prepare herself for the onset.

Read more – Warning for parasitism and horror elements

Nothing too notable at first. Her body just felt numb, which she partially expected. She was told to close her eyes during the trip, since any visions with her eyes open were said to be ‘unremarkable’.

But slowly, it started to become a bit more coherent.

An average height rabbitfolk, if not a little short. Their voice seemed nervous.

They were in some kind of expensive-looking ship with some other rabbitfolk and deoxys – many of which were in labcoats or other government uniforms. The rabbit that Yuugi’s vision seemed to be focused on was wearing a more protective-looking suit.

The ship rattled a bit, as it appeared to land.

Yuugi’s vision followed the rabbitfolk in the suit – they were speaking to some nearby cohorts, but nothing that was said seemed clear enough.

The rabbitfolk waved to their cohorts, and appeared to enter some kind of airlock.

The airlock filled up with some kind of water, and the rabbit activated their protective head bubble – and headed out of the airlock once it had filled up.

The scenery seemed otherworldly, with glowing coral-like crystal growths towering out of the abyss below.

Yuugi’s vision followed the rabbitfolk in silence for a bit, and her perspective slowly shifted to one that was farther out.

Suddenly, as opposed to her vision trailing behind the explorer, it shifted into one that faced them from the front – where Yuugi could clearly see the glassy, tendrilled creature fade in from its hiding to latch on to the explorer’s head.

The explorer immediately panicked, yelling into their communicator for what to do – but before they could do much else, the creature let out an odd-looking ooze that melted away the explorer’s head bubble, then…

It was all dark.

Suddenly, a voice echoed in the darkness – it was the explorer’s, though this time it was clear enough to be understood.

I’m not the only one. We’re all trapped here.”

I’d like to see home again, even if just once…”

But for someone with the power to do that to come along… it’s hopeless.”

And as Yuugi found herself slowly coming back down to reality, she realized she was sweating bullets.

It all felt… so hard to bear – as if she had personally been given some kind of duty.

It was a conflicted feeling that wouldn’t go away, no matter how hard she’d tried to shake it. Worst of all, the stakeholder and others thought she’d just had a bad trip and brushed Yuugi off, so she couldn’t go to them for advisory.

Out of options, Yuugi figured she had one path left.

While her line of work was only on the uppermost layers of it, Yuugi was technically no stranger to the Underdeck – almost its own city in itself, sitting in the twisting maze of corridors that made up the Ultra Station’s base. It was an unruly den of crime and debauchery, run by a supposedly ancient and powerful entity only known as ‘Oracle’.

Oracle, was, allegedly, an expert on the strange, occult, and otherworldly. It’d be difficult, but… Yuugi needed answers.

Yuugi blasted her way through the Underdeck, her sheer power now matched with an unmatched determination for the truth.

And upon finally meeting Oracle face-to-face, Yuugi demanded she tell her everything she knew about the origins of nihiline and the odd location Yuugi encountered in her trip.

Oracle seemed adamant on requesting ‘payment’ from Yuugi in exchange for what she knew, but Yuugi wasn’t keen on paying even a dime.

Oracle wasn’t a fan on Yuugi’s cocky attitude, and allowed herself to assume her unbound, anomalous form in order to ‘deal with’ her… but despite the odds, Yuugi managed to overpower even that.

The fight became a public spectacle, quickly humiliating Oracle out of her position of power. But humiliation wasn’t enough, Yuugi wanted the truth.

Oracle stated she believed her own life had gone too long and would accept dying to prevent her knowledge ‘falling into the wrong hands’… but she also admitted she’d made an important promise she still had to keep.

So, Oracle told Yuugi what she knew.

That the location that Yuugi described was the Ultra Deep Sea…

That the Ultra Deep Sea was held up by the moon palace, Lunaires…

And that she’d have to somehow take control of Lunaires in order to break the barrier to ‘free’ the souls lost there.

Yuugi immediately followed up with the question of how she could even do such a thing, to which Oracle told her it was impossible.

But… Yuugi felt she was hiding something more.

After taking Oracle to within an inch of her life, she finally confessed – there was a machine an old friend of hers had made, capable of remotely controlling Lunaires.

But that she didn’t know where it was or what happened to it – and it was at this point that Yuugi could tell Oracle was finally telling the truth.

So, with unlimited power in the Underdeck as its new big boss… Yuugi decided it was only natural for her to start her inquest into this machine.

Suika and Tuesday (31-33)

While Yuugi felt she could confidently defend her position as the boss of the Underdeck, it was admittedly a bit hard to manage it all.

Management wasn’t Yuugi’s strong suit, and in between her inquest for more nihiline to further strengthen the connection she felt requiring plenty of communication as well, Yuugi was finding it hard to find time to herself.

And seeing how the Underdeck was rife with backstabbing… Yuugi wasn’t so keen on trusting just anyone to follow her, especially given a handful of underlings running street gangs above the Underdeck had been problematic.

However, on one fateful day, while Yuugi was out and about in the entertainment district in her free time – she came across a scene of someone attempting a petty robbery. The victim seemed scared, but was standing her ground well enough, with a harsh enough growl in her voice that it was making the amateur thief hesitant.

Yuugi thought it’d be a great situation to make a spectacle out of, to show that particular underling how it’s really done… so, she brushed them aside, and quickly realized the woman they were bothering wasn’t supposed to be here.

Her hair was neat, and she had thick, rimmed glasses – and by her fashion choice alone, Yuugi could tell she wasn’t from the Underdeck. She seemed to be clutching a set of books and files closely, but since Yuugi was much taller than her, it wasn’t hard for Yuugi to grab them.

Yuugi asked the woman what she was doing in a ‘place like this’, but before the woman could respond, Yuugi’s eyes widened with intrigue at one of the research papers in the woman’s collection.

…It was about her theories of a lost machine located in the Ultra Ruins, with ‘godlike power’.

The woman proclaimed she was here to see ‘the oracle’ in order to get advice on her papers for university. And all Yuugi could do was laugh.

She simply stated that the woman would be coming with her – and didn’t leave her much of a choice.

That was how Yuugi met Suika – a now former university student from Megalopolis studying occultism. While initially quite harsh and cold towards Yuugi, Suika was quick to show interest upon learning that Yuugi knew of the machine and wanted to find it, too.

That’s where the similarities ended.

Yuugi was disappointed to hear that Suika’s reasoning for seeking out the machine was entirely different – that Suika’s theory was that the machine was powered by the brain of the ancient leader Tonantzintla, and she wanted to unseal them.

Still, she couldn’t argue that Suika was extremely knowledgeable, and a bit charming in… her own way. And as an outsider, she’d have no predispositions to betray Yuugi in order to climb the power ladder.

So, Yuugi and Suika made an agreement to work together from then on, as the two big bosses of the Underdeck – adopting the pseudonyms of Shuten-Doji and Ibaraki-Doji respectively. While Yuugi was the muscle, Suika orchestrated the behind-the-scenes busywork that Yuugi dreaded.

While the two were content as just a duo for a while, one day, Yuugi was called to ‘clean up’ a situation involving an odd-looking humanform that allegedly was seen cannibalizing someone.

Upon investigating, Yuugi found the incident-causer, but no remains of any alleged corpse to be seen. They were wearing a medical gown, and seemed terrified. They did indeed look a bit odd, and Yuugi couldn’t quite place what humanform species they were.

They begged Yuugi not to hurt them, and… their voice seemed to have an air of familiarity to it.

Not quite the same, of course. But the type of fear their tone exuded almost perfectly matched the explorer Yuugi had seen when she had been given her mission.

Yuugi figured that until this odd individual proved otherwise, she’d give them a chance.

Astoundingly, with safe shelter and computer access, it would seem this mysterious person had a knack for… cybercrime. Yuugi was more and more curious as to who this person even was, given their talent, but the person said they had no idea.

They told Yuugi the name they’d started calling themselves was Tuesday, and they had escaped a confidential government testing facility – after having been fused with the DNA of a guzzlord and being deemed a ‘failed experiment’.

So, Tuesday went on to join the existing duo of bosses – their computer skills and uncanny ravenous abilities making them invaluable.

With a growing collection of allies Yuugi could trust, she felt unstoppable. That, despite their differences, she could trust Suika with anything, and that their comradery was unbreakable.

Amity, and the bunker (34)

As one of the Underdeck’s big bosses, it was still generally up to Yuugi to delegate smaller street gangs that ran on the Station’s surface… though, this mostly just meant making a spectacle of humiliating the leaders of these gangs in order to maintain a level of fear.

One of these leaders was Kagerou, who was the leader of the largest on-surface group in Yuugi’s control – though it was still rather small compared to the gangs in the Underdeck. Yuugi found him to be a pushover who was all bark and no bite, and generally didn’t like interacting with him unless it was to punish him in some manner.

However, one day when reporting to Yuugi, Kagerou was joined by a doe-eyed young woman Yuugi had never seen before.

Kagerou explained that her name was Amity, and she was an expert thief… but something felt off about Amity.

Yuugi dismissed Kagerou, but asked for Amity to stay behind so they could talk… privately.

It was there that Yuugi learned of Amity’s odd backstory – she had lived her entire life in a research bunker in the Ultra Ruins, before being forced to leave due to rations running dry.

A secret research bunker in the Ultra Ruins…?

Yuugi pushed for more info, but Amity stood firm to even her intimidation. Unfortunately, Kagerou came back to interrupt before Yuugi could really try and shake information out of Amity, leading to Kagerou taking the brunt of Yuugi’s frustration instead.

Yuugi discussed it a bit with Suika, and Suika joined in on badgering Amity for intel as well – though Kagerou would still attempt to get between the bosses and Amity at any chance go got.

But Kagerou’s efforts were fruitless – Tuesday, who would frequently visit the Ultra Ruins, trailed Amity on one of her visits back there to try and clean out the bunker of sentimental belongings.

Upon exploring the bunker in Amity’s absence, Tuesday noted it seemed to be filled with lots of indecipherable old-empire tech, and contained many allusions to ‘the odd machine’ – though Tuesday hadn’t explored deep enough to find said machine.

This was it.

That was the moment the cannon fired off – and despite having worked so closely together for years… the fact that Suika’s ultimate motive was so different from Yuugi’s had never changed.

Arguments were more frequent, and inner workings of the Underdeck fell into chaos as Yuugi and Suika kept trying to sabotague each other in attempt to decipher the machine and take control of it first.

The infighting was threatening to tear them apart, something that was particularly distressing for Tuesday.

Unbeknownst to Yuugi, Tuesday began working with Amity, alongside an ex-government deoxys scientist and other scientists that were involved in the bunker mission in order to do something, anything to make sure neither Suika or Yuugi got their way.

And… Tuesday was successful. Tonantzintla, the old leader of the deoxys empire, was released from the machine and caught up to speed by parties who weren’t going to try and bind or manipulate them. Without Tonantzintla’s power, the machine to control Lunaires was effectively useless.

Desperation (35)

Yuugi and Suika were in complete shock over what Tuesday had done, but Suika was more quickly able to understand their point of view – plus, even if she wasn’t able to bind Tonantzintla to do her bidding, they seemed to like pestering Suika anyways, so she was content.

But Yuugi…

Yuugi couldn’t stand it.

Everyone had gotten their happy endings…

Except her.

With the avenue she’d dedicated all her hard work to gone in a flash, Yuugi felt as though the lost souls that has personally begged for her help would remain lost forever.

But…

The least she could do… was perhaps give them some company.

Travel restrictions to stop those trying to foolishly enter the Ultra Deep Sea had become increasingly tight, but for someone of Yuugi’s notoriety, it wasn’t much of a barrier. She left at a time she presumed both Suika and Tuesday to be preoccupied, knowing they would try to stop her. Though, she was under the impression that neither of them cared for her anymore.

Into the inverted sea she went.

It looked exactly as her visions described, towering coral and shadowy abyss and all.

Through the breathable waters, Yuugi announced her presence loudly…

And, as expected, she was quickly caught in the tangles of a nihilego.

What happened next was… fuzzy. Yuugi was in a state of semi-lucidity, but for what she could feel, she felt powerful.

The passage of time was nothing but a blur, as Yuugi began searching for others in this odd state. It didn’t quite feel like the nihilego was controlling her… no, she was controlling it.

But after an unspecified period… a familiar voice called out.

“YUUGI!! YOU CUNT!!”

Whirling around, even through the haze of nihiltoxin, Yuugi could see Suika clearly.

Though, she was joined by a few others – she was hand in hand with Tuesday, and there appeared to be a trio of people Yuugi didn’t recognize behind her; two quite tall, while one extremely short.

Yuugi… didn’t understand why they were here. She cried out, saying they should leave, that they won… so what more was she to them?

Suika tried arguing, but her words were spiraling into static as Yuugi’s frustration built up. Things started getting fuzzier, as if she was losing control during a bad trip.

When Yuugi didn’t respond, Suika left the group, even after they tried to pull her back. She approached Yuugi, and extended an arm to her.

She told Yuugi they’d figure out something, somehow.

But… Yuugi was still hesitant. This seemed too odd for Suika.

Suddenly, Suika recoiled back in fear – another nihilego had appeared next to Yuugi. Then another. Then a dozen more.

The group huddled closer together, and one of the tall figures with an odd arm seemed to begin charging some kind of energy.

But, instead of going to attack the group… the swarm seemed to stay around Yuugi.

Then, a voice.

A voice Yuugi could remember as clear as when she first heard it.

You tried your best – and I’m sure you can save us if you keep trying.”

But you have the chance to go home now. Please, do it for us.”

The nihilego that had fused with Yuugi completely shattered as those words processed in Yuugi’s mind.

And Yuugi fell unconscious to the seafloor.

Yuugi awoke in her room, which seemed to be the same as usual. Her whole body was in agonizing pain, yet still numb somehow.

Next to her, was Suika – who, for once, had a genuine smile on her face seeing Yuugi wake up.

Present day

Because of Yuugi’s overuse of nihiline, it seemed she was able to… overpower the control of nihilego, somehow, as well as narrowly avoid acute nihiltoxin poisoning.

Still, Yuugi was met with debilitating pain and brain fog for weeks after the incident. But with the help of both Suika and Tuesday, she was able to return to her former prime condition.

Since the unsealing on Tonantzintla, both Amity and Kagerou had been taken under the wing of a wealthy socialite – and while losing a subordinate was frustrating to Yuugi, she figured it was probably for the best.

Because now… Yuugi could truly focus on things that mattered in the moment. She knew those above would be waiting for whenever she could figure out a way to free their souls, so it was time to live in the present.

Parties, nihiline, philosophy, and hedonism awaited Yuugi – as well as the family she’d made along the way.


Skills

Brute force:

  • If there’s one thing Yuugi knows – it’s how to completely overwhelm and shut down her opponents through sheer strength. When intimidation doesn’t cut it, Yuugi is very much in good enough physical shape to body just about any challenger.
    • Yuugi also has very impressive stamina, allowing her to push even stronger opponents into a corner by holding her ground.

Mindfulness:

  • Yuugi is extremely well acquainted with her own psyche, and as such, has a very solid mental fortitude. Her decision to be ruthless is not one made from instability – it’s her choice.
    • For this reason, she’s rarely seen ‘on the floor’ of her own eternal nightclub, but rather indulging in hedonism somehow else while watching the commotion.
    • She’s quite active in spheres relating to philosophy.

Relationships

Suika – Crime family member

Yuugi and Suika rarely agree – but as much as they’d refuse to admit, they’re each other’s greatest ally and they mutually cover each others weaknesses well. As in tune with her own mind as she is, Yuugi could probably never admit to herself that she feels a deeper adoration towards Suika.


Tuesday – Crime family member

While Yuugi is rarely seen being soft at all, she has a notable soft spot for Tuesday – as Yuugi sees her like a little sister, of sorts. Yuugi doesn’t mind having to finish conflicts Tuesday starts in order to keep them safe.


Amity – Subject of interest

Yuugi believes that Amity knows things that she wants, and as such, tends to hound her a bit – with Kagerou often being the barrier between them.


Kagerou – Subordinate

Kagerou is a subordinate of Yuugi’s, running a small street gang on the Station’s surface. He also happens to be one of her most frequent subjects of torment, which has only worsened once Amity came into the picture.


Oracle – Former rival

Oracle was the figure that Yuugi ‘dethroned’ in order to become the Underdeck’s top dog. While Yuugi often calls her an old hag and thinks she’s useless, Oracle still maintains a heavy hand of control in the Underdeck’s workings despite Yuugi’s iron fist.


Minor relationships

Qing’e – Syndicate member

Yuugi has no outstanding feelings regarding Qing’e – she’d be more mad that she refuses to spill info, but the two have similar philosophies and outlooks, so Yuugi kind of gets it.


Sele – Annoying

To Yuugi, Sele was another one-night party fling… but Sele appears to feel differently, and keeps making attempts to make a deeper connection. It’s a harmless bother at most, but Yuugi wishes she’d give it a break. Yuugi is completely unaware that Sele really just wants her assets.


Tonantzintla – ?!?!?

Yuugi can’t seem to explain why, at least to herself, but seeing Suika’s attention shift so heavily to Tonantzintla upon their reawakening doesn’t… feel good. Matters are only made worse by the fact that Yuugi knows Tonantzintla is the one being she physically cannot overpower.


Isa – Sees around

No real opinions of her either way, though Yuugi enjoys the chances to embarrass Suika in front of her.


Trivia

  • Her living spaces are frequently filled with incense and a variety of scented candles.
  • She loves pillows with any form of tassel on them, and will fidget with the tassels if alone.
  • Tonantzintla intentionally keeps some distance from Yuugi, fearing what may happen if a connection with them would lead to Yuugi connecting with Yukarin – a recipe for disaster, in their words.
  • She wears a glove on her left hand in order to mask the ‘worst-looking’ of the signs of nihiline usage.

Meta commentary

  • Suika and Yuugi are named after the respective characters from Touhou.
    • …It’s an inside joke that Yuugi’s last name is ‘Ketamine’. Don’t worry about it.
