The passing of the royal torch
Or how Teru's ex passed the torch of Honorary Loud And Stinky Bastard Husband to Takumi in the nerdiest way possible. Cuz Teru's type is apparently huge dorks.
(Cuz I need to vent, so I may as well vent in the form of more OC lore. And this may as well be my contribution to Maid Day while I recover from stuffs preventing me from drawing in a pinch. orz)
Let's talk a walk back through memory lane with Pokemon XY's Battle Chateau: 'Show your strength via your title!' as they say.
To catch everyone up to speed so we're all on the same page, the Battle Chateau is a prominent location in Kalos just off yonder to 'ye olde lake bridge you've probably drove a billion miles up and down while hatching a metric fuckton of eggs from the nearby daycare at, if you weren't driving circles otherwise in Lumiose'.
The Battle Chateau is a place where trainers rotate in and out for anything from social gatherings in an arguably pretty upper-class hangout place, to catching glimpses of famous local celebrities to meet and hang out with them in person (from otherwise only meeting them for the duration of league business), and more importantly, for the purpose of doing battle for fame, glory, and some degree of profit. Many of the people participating are loaded as all hell, often awarding trainers who defeat them with all manner of high-resale treasures like golden nuggets, strings of pearls, comet shards, star pieces, bags of stardust, stuff of that sort. It's a fairly lucrative place for those craving stronger and more involved battles than just doing it the insiders-in-the-know way of hitting Lumiose's many cafes and loading up on their food through careful battle metering and then making it big on the secondhand resale market of a lot of the gifts there instead.
In Golden Fates canon, the Chateau operates in a way that blurs aspects of both the game's and anime's canon of it, so if you hear something and go 'wait, I thought it went like...", that's from the opposite end of the two. (Give or take a few liberties for this AU otherwise.)
When you join as an honorary member of the Battle Chateau, you are given a title. For the sake of consistency, I'll assume one variant of the title unless necessary later on, but know there's usually three different variants of each title and rank a member of the Battle Chateau can interchangeably use as they best prefer, which is listed lower down. The titles are NOT gender-locked, though understandably, people may be inclined to certain specific variants based on their comfort or preference on the grounds of such. Put a pin on this for later.
You become either a knight, or a baron, depending on your overall rank at the time in regards to the leagues proper. If you're far enough along in the pokemon league as it is, it's fully possible and outright common for many trainers just entering the chateau to already start at baron right out the gate, but a knight can prove their battle prowess merits in spite of their lacking or nonexistent presence in the leagues, and upgrade from knight to baron in kind.
When a guest either starts or upgrades into baron, they get a commemorative royal cape, and will then earn a new cape additionally of different colors as their title upgrades to a new rank.
In order from lowest to highest rank in the Battle Chateu, you have:
The knight, which has no cape, though trainers may either earn, or be encouraged, to wear fancy get-up to be especially immersed in the overly fancy atmosphere of the chateau itself (Yes, this pic in particular of Takumi is relevant, put a pin on it)...
Baron, who are signified with white capes, Viscount, who are signified with blue capes, Earl, who are signified with green capes, Marquis, who are signified with gold capes...
Duke, who are signified with red capes...
And finally the Grand Duke, who are signified with purple capes, and are the highest rank of the entire establishment.
In order to rank up, you need to participate in duels (willingly. You can't just force people on the spot, they have to be in on it too mind.), aka, both you and the other party have to challenge each other to pokemon battles, where your victory means you gain points to rack up toward your ranking. You get more points based on the rank of the other party, where knights are worth 1, barons are worth 2, and so on. However, you're only allowed to challenge up to your rank, but are welcome to challenge below your rank otherwise (with the exception of barons and knights being allowed to challenge one another as equals despite knight technically ranking under baron), meaning it has to involve the higher-ranked one of the two parties to make the challenge for super mismatched battles to go through. The idea is to keep things fair and leave it to the lower-ranked of the two to decide whether or not it's worth the risk taking up an open offer for a higher challenge without letting some noob just speedrun the entire damn event singling out dukes and duchesses on-sight to skip rank otherwise, which is why you'll get cases like everyone chomping at the bit of a grand duke's or grand duchess's invitation to battle, meanwhile the knight and baron have to slowly climb up rank together one stage at a time.
On top of that, in order to officially rank up and be bestowed the new title (and decals to go with), you must complete an initiation battle with a willing participant of the rank you're about to enter, and win that battle, in order to officially rank up yourself (this can be re-tried with different members so long as there's someone of that rank who is willing to do this with).
In short, the rank-ups and point thresholds look a bit something like this:
Knight / Dame / Partisan - started as this if your league rank is too low or you don't participate in league at all
Baron / Baroness / Baronum - Earn 3 points as Knight/Dame/Partisan OR Started at this if you have at least 3 league badges
Viscount / Viscountess / Viscountum - Earn 5 points as Baron/Baroness/Baronum
Earl / Countess / Lairdship - Earn 30 points as Viscount/Viscountess/Viscountum
Marquis / Marchioness / Marquem - Earn 100 points as Earl/Countess/Lairdship
Duke / Duchess / Dukum - Earn 300 points as Marquis/Marchioness/Marquem
Grand Duke / Grand Duchess / Grand Dukum - Earn 1000 points as Duke/Duchess/Dukum
Incidentally? These are NOT accumulative. You MUST earn all of these points per each tier, and the points you earned previously (although certainly can be redeemed for other goodies) don't roll over into your next rank up, which is separately counted up to Grand Duke. Meaning you must go the whole 5, 30, 100, 300, 1000, and work your way up to that damn title.
In terms of social status, the Battle Chateau is particularly famous as a fun bragging rights place and get-together: Completely optional for those simply getting by on the leagues, but immersive and fun otherwise for those willing to work a little to get a fancy title and fairly high social status.
On top of that, different ranks unlock different new services (they still retain access to services unlocked at earlier ranks of course), including the writs, which are written contract commands for which you can make an open invitation blanket-signalling or otherwise blanket-applying to any other participant a user of a writ invokes, including a more public open-invite for people to jump the cue to challenge you, an invitation to get a particularly stronger challenge for better rewards, or even an active invitation to duel a specific member. The specific writs include:
The Writ of Invitation - which mass-invites multiple trainers in general with a wish to challenge you, usually for people who want to grind those points in earnest in particular.
The Writ of Challenge - which mass-invites trainers to bring stronger and higher meta-tier caliber pokemon to challenge you, for the chance of more enticing rewards.
And the Writ of Action - which calls out a more specific member that's at your rank or the immediate rank above (for instance a Duke challenging a Grand Duke), or below your rank otherwise, and invites them to a more personal, more direct battle with that trainer to accept at their discretion. (If you're a Grand Duke, the world is pretty much your oyster at that point.)
With the exception of the Writ of Action, the Writ of Invitation and Challenge have higher ranking colors of writs to emphasize the urgency and yield a much stronger command. The main drawback is writs are expensive as balls, and higher potent writs, up to and including the Writ of Action in totality, is an exceptionally expensive-as-balls command to invoke, so it's not only a matter of careful planning, but a HUGE flex of just how deep that trainer's pockets are to invoke them in the first place.
The social status aspect mentioned earlier comes up quite a bit even here, as the gym leaders of Kalos are all typically at Marquis level, the elite four of the same region are all typically Duke level, and the champion of the region and popular socialite actress and model, Diantha, is a pretty famous example of a Grand Duchess ranked member.
So, naturally, given so many pretty big names are also participating in this stuff, a lot of trainers far and wide would gather in here and climb up the ranks in hoping to see the gym leaders, the elite four, and especially the champion, but especially trainers who either want to get a more personal glimpse of them, or who want to meet them at all in lieu of reaching them naturally through the leagues.
In their earlier and younger days as more active trainers, Kyo and Teru were also no exception.
Back when the two were much more active climbing ranks in the leagues, both of them, among their friends (and general traveling party) at the time, also were members of the Battle Chateau themselves at the time. It was around the time the grassroots were starting in what inspired the group to settle their eventual business of Papilon in what would eventually be a part of Lumiose, but in the early days of planning and setting up, all of them rotated in and out of Battle Chateau at the peak of their pokemon trainer journeys, out of which Teru and especially Kyo took off.
Then Papilon's growing pains were settling in, the trainers traveled abroad less between either adding more to Papilon's initial business or going to other regions for inspo sake on what else they can do to freshen Papilon up with and diversify their menu, and then you know the rest one fateful touchdown later in Hoenn when Tylon (mistaken for Team Rocket at the time) completely wrecked all their shit in and fractured a lot of the group, while Kyo and Teru were isekai'd and spirited off and thereafter distracted by their summoner duties since.
And then between Teru being in for a very long and steadily-maintained recovery plan of being some parts bedridden and other parts chronically ill, and both of them having massive issues being able to remain as functional pokemon trainers (but Kyo in particular nowhere near bouncing back as quickly or seamlessly like Teru did in pokemon use) due to both of their crippling triggers being anywhere near pokemon centers henceforth, their respective backgrounds in the Battle Chateau continued to get pushed further back in either of their minds for every successive book's worth of bullshit that comes up to attack Zenith (but especially Askr and Embla) with, and the rest was a distant faded memory.
Or at least it was, until it was eventually unearthed like ancient fossils over time, once both Kyo and Teru continued to move on, grow, meet new people, grow attached to said people, and then get more involved with said people's lives in pretty significant political ways.
So of the six summoners, to recap their support situations...
Erin has no political background, and Lif is in a tentative position sorting between Gustav, Henriette, and both Alfonse and Sharena (should the latter two choose, he and Erin can act as the defacto rulers after Gustav and Henriette to free up duties to let Alfonse and Sharena continue their active roles as Order of Heroes, but if they take up active rulership instead, priorities default to either of them rather than him).
Hrid (like Gunnthra) didn't take up the throne of Nifl, as the current queen and his mother, Eliva, is still active queen of Nifl, so who rules Nifl after her between either him or Gunnthra isn't necessary to press on just yet.
Ryoma is king of Hoshido while Camilla is actively queen-consort, meanwhile Erin is appointed as Summoner of Hoshido otherwise (in parallel to Teru as her counterpart) as decreed by Corrin (Corrin is NOT her support to be clear, but she's close in a friend-familial way to both Erin and Teru among others) to ensure Ryoma and Xander stay on track maintaining Nohr and Hoshido's peace.
Sparrow and Ephrel also have no political background (Ephrel's background as part of an underground hacking group with some powerful hackers they can call favors from, notwithstanding,), meanwhile barring Robin, the key political standouts include Lyon and Chrom.
Out of the two, Robin gives Chrom the ability to resume rulership over his world's Yilisse (since Chrom's original world was completely destroyed sans him and Ephrel), and Chrom, rather than pick a spouse at random, pretty much designated ALL of them to be his lord-consorts, though Robin and Lyon are usually the most active between Robin's experience with where his Yilisse left off and Lyon's experience as an actual ruler otherwise.
While Lyon technically has stakes in his proper country otherwise in Grado, the problem comes in not just Grado's REALLY bad state of affairs last it was left following his initial death, but being a whole landmine of triggers of where to even begin with that in regards to requiring him to finally face the Renais twins at the very least. Whatever moves he makes toward Grado are subtle and uncredited (or credited to Yilisstol generally), and that's only with very careful navigating on Robin's and Ephrel's parts to even get there if Sparrow doesn't otherwise rotate duties with them.
And then there's Eclair, who as you all know by now, he very technically has claims of being an Asgardian god, son of the war god Thorr and all the bragging rights and pitfalls that title bestows (mostly the pitfalls...), which leaves Kyo and Teru to sort out.
Now in regards to Kyo (since he's with Eclair too), the original thought was he and Kaze are the only ones without titles at all (unless you consider both Kaze and Saizo being the direct sons of the head of the clan Saizo the Fourth as a title, but even then it was Kaze's brother Saizo (the fifth) who took the title officially), Lifonse, in a similar move as Lif, stepped down his claim of Askr in totality (but is even farther removed from both Side A and Side B Askrs in comparison to Lif's arrangement), and Kamui similarly stepped down his ties to Valla, Hoshido, or Nohr in favor of Corrin in a similar manner as Azura (since his original world was abandoned, and this world's Corrin is the current ruler of Valla while Xander and Ryoma are current rulers of Nohr and Hoshido otherwise, so while he serves assistance to Corrin, he doesn't lay any claim otherwise even with Corrin's willingness to share roles).
That leaves Cronos as the only active ruler of the zoanthrope kingdom of his own world, which is completely dwarfed by basically all of Corrin's familys' countries, and so small that his series didn't even give it an official name.
Meanwhile, rounding out Teru, finally, there's the aforementioned Xander who is current king of Nohr, Takumi as king-consort since he has the most rulership experience in a mirror as Camilla was on Ryoma's side, and the aforementioned Gunnthra is currently on standby (like mentioned similarly as Hrid's doing) given Eliva is the current active ruler of Nifl, and she otherwise rotates queen-consort roles whenever Takumi branches out elsewhere in the meantime.
Neither Reinhardt nor Tethys have royal titles, and Teru was originally thought not to have any either, though Reinhardt in particular had also been rather humble of his title otherwise as General of Gelbritter (Friege) and being otherwise a possible reincarnation of the legendary Thrud. Though, in light of Xander primarily alternating between either accepting Corrin's decree of Teru being Summoner of Nohr, or his king-consort, or otherwise rotating that offer to Takumi or Gunnthra instead, should it be decided that Gunnthra is to rule Nifl instead, Reinhardt and Tethys are thought to best assist as her consorts in that case, given Teru's and especially Takumi's direct experience of Nohr and Hoshido otherwise being better aids with Xander.
So catching up with all of that, let's walk back to Kyo and Teru.
Like mentioned before, it was originally thought the two had no titles. They were, after all, pretty regular people with pretty mundane lives, they were otherwise co-owners of a pretty hip restaurant, but summoners otherwise, and up to the point royal titles came up in heavy discussion, neither remotely alluded or suggested otherwise that wouldn't otherwise be awarded as consort rights from one of their other supports.
So it came as a big surprise, and point of confusion then, when between both of their support circles being much more invested in the World of Pokemon and their past as trainers, on top of certain supports being rather heavily teased with the promise of juicy intel for a price by that world's Anna (yes, turns out, the outer worlds each have their own Annas as well), supports like Takumi and Kamui both shared the same brain cell and bit the bullet and paid the troll tolls for the World of Pokemon's Anna to give them the shocking discovery that Teru and Kyo are both members of nobility, albeit skewing the full context that these titles came from the Battle Chateau, and have different connotations as fellow dukes in the pokemon world (but especially that particular chateau) compared to, say, the duchy of Grannvale, Lord Sigurd.
More, the subject of both their pasts as trainers is a painful and tricky subject to navigate. After all, both of them were still reeling from their traumatic experiences of both being kidnapped, tortured with cruel experiments, and transformed into powerful shapeshifters at the cost of lasting, rippling trauma.
Teru only somewhat eased back in his more passive uses of his pokemon for the betterment of Nohr's ecosystem to stimulate it catching up to Hoshido's for the long term, yet in more intimate moments, his supports knows well how violently reactive he gets, and how much he has to hold back, at being approached or physically touched the wrong way. Even some of his pokemon still have lasting scars of his other incidents he had to bounce back from on top of the initial kidnapping, chief among them his signature pokemon in his shaymin, Papri.
Kyo, meanwhile, traded being way better off physically with being way worse off in regards to utilizing his pokemon for more than transport or glorified-pet sake, and he had a much harsher time and a far stronger panic reaction to anything lab-like or pokemon-center-like that even with Erin among others assisting in taking over healing duties (as in she'll borrow both their pokemon and take them to heal at the centers in their place, usually accompanied by Lif doing it), Kyo was a lot slower to accept this arrangement, and even with it, still pointedly fought his own battles or still relied on his own body and powers while avoiding pokemon battles entirely and/or dipping into his on-hand supplies out of force of habit otherwise, and gets antsy whenever his supports try to do pokemon battles in his place (particularly the pokemon Kamui and Lifonse inherited from their previous (dead) Kyo).
The supports DID eventually sort out that their titles are more of a show of their battle prowess and strength than ruling influence, but even then, both of them suddenly being confronted with some variation of "WHY DIDN'T YOU TELL ME YOU'RE A DUKE?!" only for them to STILL walk away with overestimating their titles, it's like having the equivalent of those paper crowns from Burger King and having your Arthurian-sort-of displaced-time-period royal himbo-spouse be like:
"Ah yes, forgive me for not recognizing your full title sooner, Lord-King of Burg."
So we're all caught up on what Battle Chateau is and does, everyone's titles, and Teru and Kyo having them.
"What does it have to do with this little dipshit?"
So like I said in the past, Kyo and Teru both hail from the World of Pokemon as former trainers. Teru still somewhat embraces the role slowly, carefully, and in spurts, meanwhile Kyo toes the line of zoanthrope-adjacent in focusing significantly more on his own shapeshifting powers instead, give or take occasionally bringing his pokemon out as transport, pets, emotional support, and very little else.
Occasionally, Teru and Kyo have also colluded with summoners of other worlds, other sets of monsters, and swapped hands with them, notably including Sparrow and Ephrel (who hail each from a World of Steel interconnected with the Digital World and primarily both handle digimon likewise), or eventual summoners like Mahiro (who has strong connections with the Palapagos Islands and had prior connections to the World of Discs, so has equal dealings with (Palworld) pals and (Monster Rancher) monsters respectively), with Teru and Sparrow in particular being frequent traders of one another for various purposes, leading to eventual byproducts of these trades like Takumi's eventual digimon partner in Pikachu/Piki (a patamon).
Of Teru's supports, Takumi is equal amounts the one who is the stinkiest bastard about whining and bitching about having no interest in monsters of any sorts and being widely unimpressed by babysitting the aforementioned patamon at first (to a point he named it "Pikachu" in a very "pikachu, patachu, whatever I don't give a shit" way), but then very suspiciously is also one of the most involved out of Teru's supports in being surprisingly the most versed in absorbing info on monster care with all the enthusiasm his siblings compare with his handrearing of kinshi, especially when Hinoka and especially Ryoma had their hands tied way too much with other things to be nearly as involved or willing to handrear monsters, so Takumi ate that shit up as an expert-in-the-making as a thing he can lay claim on that neither of his older siblings are nearly as versed in (and eventually it softened his heart to the monsters too, like the aforementioned "Pikachu" eventually being properly nicknamed "Piki" as he warmed up to him more... when Leo isn't otherwise nicknaming him Piggy for being a little shit of his own too. Which Takumi has equally yelled at Leo over, just as he's also occasionally used the nickname himself too when Piki misbehaves.)
So, needless to say, when a lot of the other supports are either also too busy to really deep dive into pokemon like Takumi can, or noticeably modestly backed off into the sidelines and were much more quiet keeping up after all in favor of letting Takumi shine instead, Takumi actually heard Teru out more about how the chateau works, what his title meant in full, and the past experiences Teru reminisced on, back when he and Kyo used to climb up the ranks together back when they were a couple, only for Teru to slow down over time in favor of refocusing on the restaurant, in sharp contrast to Kyo being much more engaged in the challenge in spite of the monotony of so many battles the highest title of all would call for, and so Teru stopped at 492 points of the requisite 1,000 to hit Grand Dukedom, meanwhile Kyo blew the point requirement out the water, defeated Champion Diantha, and earned his title as Grand Duke by comparison, prior to The Incident and then both retiring as summoners.
As much as the hype of having his title blown out of proportion did get to Teru enough to share interest in potentially finishing out the rest of his point requirements to complete that final hurdle, and he was especially egged on by his supports, unfortunately, there was only so much wishful thinking could do for him.
After all, of the two, he was left in a very precarious state health-wise. Either so sickly and weak he'd collapse on the spot, or his stability would potentially put him at risk. While he had a better handling on the latter thanks to everyone's efforts to let him actually heal and recover from his past incidents and traumas, unfortunately, in practice bouts between his pokemon and the budding team Takumi tried his hand to raise, Teru couldn't reliably endure the physical strain it took to take up trainer duties between actually making it to the chateau, and actually staying lucid enough without collapsing to stay alert and attentive enough to command his pokemon properly, even with mitigation attempts from his supports shadowing him, to him leaning on physical aids or seats, or taking long breaks in between practice bouts.
His pokemon might be capable, but he himself wasn't. A few battles, maybe, but roughly 508 battles, even in rotating week-long shifts, already made his eyes glaze over even back when he was way healthier and stronger, let alone now.
But there was a generous loophole to how the chateau works. After all, it was moreso for fun and games than a super heavily-regulated thing, so there were leeways to how the titles and ranks worked.
It's a fairly regular occurrence for trainers of all walks of life to take up the mantle of pokemon training as either competitive battlers, or casual battlers, even when they were too young to technically qualify as certified trainers (so they couldn't participate in the leagues yet if under 10, the minimum age requirement, but with supervision there's been regular cases of toddlers outright borrowing the pokemon of their older family for battle), and/or cases of other trainers whose journeys were spent in tandem with a close companion, a caretaker, or even a ward who battles in their stead if not in tandem with them.
Therefore, it was not entirely unheard of for case-by-case instances to crop up where a title earned by one trainer had been loaned out or outright bestowed on another, or someone earning the title in honor of a different trainer they're battling in place for, provided they fulfill certain requirements based on what's specifically going on between either parties.
With Takumi's insistence to investigate this, between some parts genuinely feeling inspired to help nudge Teru past that long-forgotten finish line when Teru couldn't handle it alone, and other parts sticking it to Ryoma, Hinoka and Leo otherwise, he convinced Teru to be willing to negotiate with the organizers behind the chateau on allowing Takumi to assist in battling in Teru's stead to help him reach Grand Duke.
Unfortunately, given Takumi was a complete nobody in regards to his history (NO league history whatsoever, no known background with pokemon that can be actually documented and cited in the World of Pokemon proper, and he's trying to man a fledgling team, meanwhile claiming he'll take charge of another trainer of a sharply wide skill and experience gap from him), his initial chances weren't very optimistic, but they were willing to allow him to resume Teru's prior progress toward Great Dukedom with an initial 492 point start as Duke, but only under the condition that Takumi reaches the title of duke on his own merits first.
So armed with appropriate modern-esque butler attire, a ragtag bunch of pokemon misfits, and a dream, to his credit, he did a damn good job climbing the ranks on his own merits.
Granted, he had to carefully manage his team in between Order of Heroes duties and otherwise, and he had to pick up things in rotation between whoever's available and avoiding paying for the writs cuz 'nuts to all that' to their prices, but he gradually ascended the ranks on his own accord as supports, family, and friends rotated in and out of looking on, and eventually, Takumi managed to reach the title of duke while finally picking up the rest of the pace of where Teru left off so long ago.
And much like what Teru gave up originally on, it was a massive time and repetition slog, and he hated every moment of it while loudly making it VERY known how much he hated it for all of Askr and Hoshido to hear. (Whether they liked to or not.)
But damned if he didn't do it, and after careful navigation and battle prowess, he hit the 1,000 mark, and qualified for the one final battle he needed to make it all count.
And there lies the problem, but not for the reasons Takumi prepared for.
Remember: You not only need to meet the point requirements, but you also needed to battle someone of the rank you're trying to upgrade to. In his case: A Grand Duke/Duchess/Dukum.
The problem? A LOT of Grand Dukes fell out of the circuit entirely, due to either being too busy elsewhere, retiring (officially or otherwise) once the glow of reaching said title fell off in favor of more recent and higher prestiges to pursue (like the leagues, or various tournaments, or stuff of that sort), or a concerning amount of them just up and disappeared entirely, fate unknown (...like a certain mass exodus from a certain sudden shutdown. For example.)
So between famous cases like Diantha being way too busy to entertain a battle with him (she's a full time model, actress, and already juggles a lot between being a famous celebrity and the region's champion, cut her a break), and many other cases being flat out gone in some form or fashion, there isn't actually a grand duke available for Takumi to battle, and given how high a bar prior grand dukes already set battle-wise, it wasn't in the spirit of the facility staff to measure up to step in their place.
BUT! Fortunately for Duke Taco Truck, that's not where his claim to fame ends.
Soon after finding out Takumi got softlocked out of honoring Teru's legacy, and seeing how crushed Takumi got in falling just shy of the finish line no matter how proud his supports (Teru especially) were of him reaching as far as he had for a complete newbie to an entire world of battle beasties, just when Takumi was nearly ready to throw in the towel and accept maybe that's as far as he could go, like it or not, he ends up getting a notice.
A trainer sent him an invitation back to the Battle Chateau, and challenged him to a personal battle, via the Writ of Action.
A Grand Dukum returned, out of retirement, specifically to single out and challenge him.
And after hauling the fastest of ass all the way from Shirasagi to Askr to grab Teru and drag him through Campfrier, then well back up to the chateau, he was finally met with the last battle he had to do, after a long and miserable slog of chain battles leading up.
He was not only met up there by familiar faces like Corrin and Kamui, Erin and Ryoma, etc, on the opposite end of the battlefield, but the return of the once-retired Grand Dukum, Kyo.
Despite his discomforts of battling with pokemon again, and despite thinking he wouldn't be able to handle risking his pokemon in battle again, Kyo was working on his own internal battles in easing back into the once familiar thrills and joys of battling he used to have before Tylon shit all over it.
He noticed Takumi's entire struggles, at first because Kamui would keep tabs of it and then word-vomit all over him about it, then he himself taking notice of his own accord, and while he still has his own issues to deal with post-battle, the combined effort Takumi demonstrated to follow the same challenges he once did, only for all the other grand dukes to drop the ball, he worked his way back into being just enough ok with battling again long enough to help Takumi across the finish line, and he practically dragged Erin with him to help give him peace of mind for the parts of the battle he still couldn't cope with (the heal-trip afterwards).
This in itself already surprised Teru plenty. Takumi getting this far, his ex actually working himself up in the interim meanwhile to do this for him over some dumb title, being in the chateau at all, it was a lot already to take in.
And then Takumi ups the ante by using all his hoarded up winnings to throw down a Black Writ of Challenge (black being the highest and most expensive color-ranking, bear in mind,) in direct response. If Kyo was going to go through this in direct spite of his discomforts, just for them, Takumi wanted him to go all-out then.
Which Takumi near-instantly regretted mid-start of the battle upon fully taking in Kyo's team, and having practically invited Kyo to bring in big guns like a mega-evolved pokemon, his gigantamaxed starter, and a fucking crown-sword zacian (who he knew from prior knowledge was mysteriously 'banned' from participating in most tournaments period from Kamui), and pretty much put Takumi through the whole nine yards of every battle gimmick across the gens in one battle. He'd help Takumi try for the title, but by the gods of all nine realms and then some was Takumi gonna work for it.
The 'OH SHIT's to follow were loud and frequent, to say the least.
But in spite of very quickly Fucking Around, he just barely avoided Finding Out, and while it was up in the air how much Kyo went all-out and how much was him still holding back somewhat, especially at the very last instant, Takumi did end up defeating Kyo by the skin of his teeth, right in front of his family and Teru no less, and retroactively pushed Teru up to Grand Duke with matching capes to go with him of it.
And then he continued the time-honored-tradition-now of all other Grand Dukes that came before him held, and fucked right out of that chateau immediately after getting that title two-fold, cuz after 9000 battles, and getting nearly ran over by Angry Dergcopter, Sniper Gecko, Swordy Murder Dog, and roughly four gens worth of battle gimmicks, he only had just enough pokemon-related spoons to be absolutely insufferable to Leo about his new Grand Dukedom for a good chunk of a month, and very little battle-drive in him otherwise after. (Fair play to him too.)
