So, here's me doing another stab at Anubis of the Highway Thieves' 'Of Jumping Dimensions and Drunken Marriages' challenge. And this is a crossover I've been meaning to do for a little while. While it's not the first such crossover (that honour belongs to a Naruto fanfic attempt), it's my first attempt at crossing the Potterverse with this series, which is a shame, considering that I think this series has a lot of crossover potential, but only two Potterverse fics (one a single chapter, the other a decent but not stellar fic) have been made so far.

I am talking about GATE: Thus the JSDF Fought There.

It actually took some time to get this working. I originally considered answering my own 'Harry Mercury' challenge (to those of you familiar with GATE, can you imagine Harry raised by Rory Mercury? You may excuse yourself to get clean underpants if need be), and while that went nowhere, after considerable discussion with Leaf Ranger and especially Arawn D Draven, I've come up with this fic. It features a post-Hogwarts Harry, Luna and Hermione crossing over to the world beyond the Gate, a few years before the Gate appears in Japan. Not a Lunar Harmony fic, though. Harry's getting paired with Tyuule (albeit a Tyuule who was saved from being Zorzal's sex slave) and possibly Delilah.

Also, this marks the third time that I've paired Harry with a bunny girl, after Mjrn in my Final Fantasy XII crossover Nitimur in Vetitum, and Velvet in my RWBY crossover Pulvis et Umbra Sumus. Huh. And in each of those, I gave it a pretentious Latin title. Oh well. It won't count if it doesn't get off the ground. Speaking of pretentious Latin titles, this title means 'the small under the huge', meaning the strong protecting the weak, a theme that will grow throughout the story.

Finally, this is unlikely to be the last GATE crossover I do. In fact, I'm strongly considering doing a crossover with One Punch Man, in accordance with my 'GATE: Thus the Hero's Association Fought There' challenge.

I should thank Leaf Ranger and Arawn D Draven for their patience with my questions about GATE canon beyond the anime. While I was aware of some plot developments, I wanted clarification.


PARVA SUB INGENTI

CHAPTER 1:

LUNACY, LIQUOR AND LAGOMORPHIC LADIES

"I love the smell of Fiendfyre in the morning. Smells like…victory."

Hermione Granger glanced at the form of Luna Lovegood as she skipped alongside her, and grimaced. Note to self, she thought. Do not show Luna too many more films. She's getting ideas. Then again, Hermione couldn't remember ever showing Luna Apocalypse Now. In fact, she thought Luna was more into science fiction and fantasy.

Not that much Fiendfyre, or indeed fire in general, had been used here on this battlefield. She was grateful for that. Getting caught up in a local conflict was bad enough, but she didn't think she wanted to smell roasted human flesh.

How did she get into this mess? Oh, right, that was why. She joined the Unspeakables. She decided she wanted to investigate the Veil when she, along with Luna and Harry, realised it was a portal to another world. And with their respective relationships with the Weasleys having gone somewhat sour due to various circumstances, they decided to go through it, regardless of whether or not it was a one-way trip.

And now, here they were, not exactly stranded in a world that was a hybrid of a European medieval fantasy world and the Roman Empire, but still, going back meant being ferried by Phoenix or House Elf, and their mission was mostly exploration. Not to mention that they were to avoid getting involved.

Unfortunately, that plan sort of went out the window when she and Luna got separated from Harry, and they'd lost their original homing Portkeys. Yesterday afternoon, they had met a retreating Imperial convoy who were escorting the now-catatonic Prince Zorzal El Caesar (heir to the throne and all-round prick, apparently). They were able to get some information, about how a sorcerer had been captured and taken to their camp, only to free himself and save Tyuule, Queen of the Bunny Warriors, who had been captured and brought to the Imperial camp to negotiate the surrender of her people. Said sorcerer had then helped the Bunny Warriors turn the tide of their battle against Zorzal's forces, helped by the fact that Zorzal had been tortured into catatonia by dark magic.

The soldiers looked set to try their luck with Hermione and Luna, until their current travelling companion made herself known. And they clearly didn't want to evoke the wrath of said companion, even if she didn't look like she would be much against a group of enemies. Then again, looks could be deceiving.

Their travelling companion seemed to be a girl in her early teens, wearing a black, frilly dress trimmed in red, with a disturbingly high hemline. Hermione recalled that this seemed to be a Gothic Lolita style of dress. The girl had black hair, glossy like a raven's feathers, and crimson eyes. On top of her head was a bow that gave her a vaguely feline profile. Most extraordinary of all was the massive halberd she was wielding, too large and heavy for a child her apparent age to be wielding. She seemed more like a cosplayer at some sort of convention than anything even for an average fantasy world.

There was something vaguely feline about her, and not just with the bow that looked like cat ears. There was the same playful attitude, a mixture of simple childishness and a bloodthirstiness, a savagery that lay beneath the beauty. Hermione briefly recalled William Blake's poem Tyger! Tyger!, and marvelled at the fearful symmetry here. She wondered how Crookshanks would deal with her, before wincing at the reminder of her faithful pet, beheaded and then having his head mailed to her with a note saying You're Next, Mudblood by Theodore Nott a few months back. Another reason to leave, along with her cooling relationship with Ron.

In any case, their travelling companion, whom they had met after their first day in this world, was Rory Mercury. Despite her apparent age, she was actually over 900 years old, given immortality by the deity she was the Apostle of, the war god Emroy. She was also ridiculously strong, skilled, and could regenerate from pretty much any wound. Basically, she was an unstoppable bloodthirsty killing machine.

And Luna, of course, had promptly called Rory her new friend, much to Hermione's bemusement, and Rory's initial bemusement, followed by amusement. So now, they had a possibly psychotic, definitely dangerous, demigod tagging along. Hermione was admittedly worried, especially when Rory stated why she was accompanying them.

She had apparently been approached by a rival Apostle, Giselle, the herald of the local death god, impossibly called 'Hardy'. Luna had promptly asked whether there was another one called 'Laurel(1)'. In any case, Giselle had told Rory that a trio of wizards from another world had fallen through one of Hardy's lesser gateways, one of whom was carrying three relics Hardy had, on a whim, given to another trio of wizards, just to see what chaos would unfold.

Still, they had confirmation of something from Rory, good news. But they needed to find Harry first, and by the time they had thought to use a Patronus, the Patronus didn't go to Harry. This meant he was kipping in his expanded trunk. The Point Me spell worked fine, so he was still alive.

But the landscape they were walking through, towards one of the larger settlements of the Bunny Warriors, bore the scars of battle. Craters from magical explosions, blood and viscera, though the bodies proper seemed to have been dealt with. Vanished by magic, then?

Rory shivered, but not in fear. Instead, it seemed to be delight. "Oh, I should have been here. I felt their demises from so far away. It was so…wonderful."

"Too much information," Luna remarked. And when Luna Lovegood, a Ravenclaw born and bred despite her eccentricities and wild imagination, thought that something was 'too much information', you know it disturbed her. Hermione knew what she meant. Rory acted as a conduit to Emroy, sending him the souls of those perishing in battle close to her. In the process, it acted almost like an aphrodisiac, according to the Apostle herself. "You need a hobby. I mean, aside from bloodshed, slaughter, and dressing like a Gothic Lolita."

Rory scowled. She had picked up English quite readily due to her demigod status, so they hadn't used a translation charm since yesterday. "The last time I had a hobby, which was rare coin collecting by the way, Giselle stole my collection on Hardy's orders and put them in a deep cave for me to retrieve, where Hardy'd be able to get me."

"Wow," Hermione said. "That's…petty. Doesn't she understand the concept of consent? That no means no?"

Rory shrugged. "Consent is something too many mortals disregard, and some gods are no different. At least Emroy cares not from whence the blood flows." Rory grinned in her unnerving manner. "Only that there is blood, and why it is shed(2)."

"Your cleaning bill must be big," Luna remarked.

"Enchanted clothing," Rory said with a smile. "Regenerates holes, repels stains, and always smells like…well, whatever I'm in the mood for."

"Which appears to be citrus," Hermione said, sniffing. "Oranges?"

"Blood oranges," Rory and Luna said simultaneously, before high-fiving. Hermione merely facepalmed. Of course it was.

The gate to the settlement was guarded by a pair of sentries, both of whom were athletic, beautiful women, dressed in clothing that, while not skimpy per se, showed quite a bit of skin. However, they weren't human: a pair of rabbit-like ears poked through their hair, and fur covered much of their arms and legs. These, then, were the Bunny Warriors. They looked wary, and a little fatigued. One of them looked up as they approached. "Drana'c cusauha lusehk," Hermione heard her say, wincing that she didn't replace the translation charm since yesterday.

"Ec dryd…ec dryd dra Ybucma uv Emroy, Rory Mercury?" the other sentry asked.

"Ed ec!" the first sentry said, nodding her head. They looked wary of the newcomers, but there was also hope on their faces.

Rory approached them, and said, "Re! E's lineuic, tu oui rybbah du ryja y haf Hume syka eh ouin lysb?"

The first sentry nodded once more. "Oac, ehtaat, Myto Mercury. Ra nacliat Xiaah Tyuule eh ran desa uv haat vnus dryd jema Hume Zorzal. Fedruid res, uin pyddmac syo hud ryja paah fuh, yht ajah drah, ed fyc lmuca." She looked at Hermione and Luna, the latter of whom waved cheerfully, and asked, "Yht fru yna draca yllusbyhoehk ouin yikicd bancuhyka?"

"Drao yna vneahtc uv dra syka fru rambat oui. Drao ryja paah caynlrehk vun res. Ra kuac po dra hysa uv Harry Potter, tuac ra hud?"

"Oac. Ev drao yna dnimo rec vneahtc, drah drao yna vneahtc uv uin baubma duu. Rufajan, Xiaah Tyuule nadenat fedr dra Ruhuinat Cunlanan Harry Potter vun dra hekrd. Drao fana...nydran tnihg."

Rory snickered to herself. "Oh dear," she said in English. "Your friend was rather busy, saving their queen, Tyuule. He's already being called an 'Honoured Sorcerer' by them for fighting for them, though apparently it was still a fairly close battle. Apparently they were last seen rather heavily drunk."

Hermione facepalmed once more. "Oh, Harry, what have you gotten yourself into now?"

"Probably someone's bed," Luna said cheerfully. "He's too pent up. About time he got laid."

Rory cackled, and Hermione growled, "Luna Lachesis Lovegood(3), this is serious."

"We haven't found him yet, remember? We were looking for Harry."

"Who was last seen, heavily drunk, with the Queen of a warrior race. We're trying to explore the world beyond the Veil. I know complications are inevitable, especially where Harry is involved, but we need to keep them to a minimum." Though Hermione knew that she would probably end up causing more than a few waves here. Slavery, especially sex slavery, was ridiculously common in this world, according to Rory. House Elves in symbiosis with the magic of their employers was one thing. And some part of her wouldn't let that stand.


The first thing he noticed was the pain, like someone was taking the Sword of Godric Gryffindor, Basilisk venom and all, and using his brain as a scabbard. The second thing he noticed was the taste in his mouth, like he'd been forced to eat a Dungbomb and it went off in his mouth. The third thing he noticed was the pair of larger furry things wrapped around him. The fourth was that he could feel someone of the female persuasion pressing into his naked back, what had to be (thankfully) cloth-covered breasts pressing into his back. As he opened his eyes blearily (thankfully, his bedroom in the expanded trunk was dim enough so that it didn't hurt his currently very sensitive eyes), he realised that those last two things were connected, as he had a pair of furry arms wrapped around his torso, though the delicate and very feminine hands were not covered in fur.

And then, he saw something on a finger of one of said hands that sent a chill down his spine.

A ring. A very familiar ring.

Before he could process this, he felt his bedmate shift behind him, yawning gently, wriggling out from behind him. He twisted around to look at his bedmate. Morning amnesia and a hangover conspired to keep him from recognising her, at least immediately. Still, he stared at the woman as she moved what looked like a traffic cone out of the bed. Or whatever she was.

True, she had a shapely, athletic, and yet surprisingly buxom body, concealed by a shift with matching panties, or at least the medieval equivalent. Snow white hair framed pale features that looked to be someone in their twenties, while crimson eyes peered at him, a little blearily at first, but, thankfully, she didn't seem to object to being in his bed, especially if the rather gentle smile she favoured him with was any indication.

But she had fur, the same colour as her hair, covering part of her arms and legs. And protruding from her hair were a pair of long ears, like those of a rabbit.

After a moment's uncertainty, he said, "Uhhh, good morning?"

She winced, clutching her own head. "Not so loud. I didn't drink quite as much as you did, but I still have a hangover. Wait a moment…you left these out." She reached over to the bedside table, and plucked some familiar vials from it. She handed one over to Harry, and drank hers herself, before grimacing. "Ugh, it tastes like Ma Nuga excrement smells," she complained.

Harry drank his own, and grimaced in his own turn, though the headache and the nausea went away almost instantly. "If a Ma Nuga is your equivalent of a cow, then I agree. It does taste like cowpats would."

The rabbit woman nodded. "Still, better a hangover in freedom than suffering in slavery," she mused, before peering at him. "…You don't remember?"

"I remember a lot of drinking, we'd just fought what looked like Roman legionnaires…oh! Wait! You're Queen Tyuule of the Bunny Warriors!" Harry said, speaking his thoughts out loud. He then paled. "Shit…did we…"

"We only slept together in the most literal sense if that's what you're worried about," Tyuule said. "You were a perfect gentleman, even when drunk. More than many Humes I have met(4)."

Harry remembered something of last night. There had been a massive celebration about how they managed to win, albeit a hard-won victory, against the forces of the Saderan Empire. He'd gotten to talking with Tyuule as the drinks ran more and more. About the expectations foisted upon them, the sacrifices they had been forced to make. And then…a suggestion. An insane suggestion that they still accepted.

Harry realised he could feel metal on his own ring finger. He stared at it. The Potter marriage ring. Used to officially bind husband and wife in a magical marriage. They were actually rarely used for a few reasons: the binding was for life, which was potentially dangerous. However, to counter that, they wouldn't actually allow any magical binding to take place without some sort of compatibility involved.

"…We're married?" Harry asked, in shock.

She had the decency to look sheepish. "Yes. You are now my official consort..."

CHAPTER 1 ANNOTATIONS:

Well, at least it isn't Vegas. And at least Tyuule hasn't been basically made Zorzal's sex slave. And yes, I used Al Bhed for the Bunny Warriors' language.

1. If you haven't heard of Stan Laurel and Oliver Hardy, shame on you.

2. I wouldn't be surprised if Emroy was basically Khorne from Warhammer.

3. This version of Luna's full name was taken from Silently Watches' Faery Heroes.

4. I actually chose to use the term 'Hume' here as a bit of a nod to Final Fantasy XII. I mean, after all, the Bunny Warriors look a bit like a ripoff of the Viera, and 'Humes' is the term used for humans in that game, so…why not?
