A Crossover between Code Geass and High School D×D by S. Silea. It follows the popular Fandom-Specific Plot of placing Lelouch in a different world after his canonical death.
Topple Your Kings
stands out for its remarkably on-point portrayal of Lelouch Lamperouge as he adapts, alone and Depowered, to a new world after completing his Zero Requiem, with only his wits and experiences to rely on in a world with Devils, Angels, Fallen, and Dragons.
Sadly a Dead Fic, last updated on June 12, 2017, after 8 chapters and a little over 50,000 words.
Topple Your Kings provides examples of:
- Accidental Proposal: Lelouch didn't know that defeating Sona in chess was the sole requirement of her Engagement Challenge.
- Always Someone Better: As in D×D canon, Sona is the best chess player of her generation, to the point Kiba repeatedly calls Lelouch insane for goading her into a match. It's only past the midgame that Sona, and later on the others, realized that the one-sided match they were expecting wasn't the one they were going to get.Sona Sitri was a prodigy. What's more, she was a prodigy with experience and practice. He hesitated to use the word conventional, for though she played the traditional, she took it to the level of the unique.
But she was no Schneizel. - Ascended Extra: The story gives more focus to the dealings of the Church, but the fic goes dormant before such plotlines could really take off.
- Asshole Victim: Lelouch kills Valper Galilei and helps to get Freed Sellzen killed. Neither of them will be missed.
- Batman Gambit: How does Lelouch negotiate his way into more information about the Devils? He offers Sona the "opportunity to lose to him in a game of chess", knowing that a chess player and young noble like her wouldn't take such a challenge laying down.
- The Bet: There's a plot-relevant one in chapter 2 where Lelouch will either gain more information about the supernatural, of desist to looking into it for good, depending on the result of a game of chess against Sona.
- Betty and Veronica: Lelouch seems to have caught the romantic attention of Sona, the by-the-book Student Council President of Kuoh Academy, and Akeno, the bombshell Fallen who seems to only speak in innuendo around the guy. Interestingly, their interpersonal dynamics with him are the opposite as well: Lelouch's tendency for high-risk high-return actions and delinquent-like gambling lifestyle bother Sona who would rather like him to channel his talents into safer and more productive endeavours, whereas his nonchalance in the face of relentless teasing and suggestive wordplay only spurs Akeno to try harder.
- Birds of a Feather: Lelouch and Kiba became acquaintances despite being in different grades and years because they frequently ran into each other a lunchtime while hiding from their respective Instant Fan Clubs.
- Born Unlucky: Lampshaded. When Lelouch's plan to steal two Excaliburs from Valper Galilei and kill the guy went off without a hitch, he got kinda suspicious.
- Brought Down to Normal: Lelouch loses his Geass upon arrival to D×D!Earth.
- Combat Pragmatist: Lelouch has no talent in a fight and he knows it, so he won't hesitate to resort to dirty tactics. Like shooting Valper Galilei in the back while disguised as Freed Sellzen in order to recover the Excaliburs.
- Comically Missing the Point: Rias gives Koneko a look for silently accepting a wad of money from Lelouch (It Makes Sense in Context). Koneko gets the hint wrong and thanks him for it, when Rias was obviously upset with her accepting money from him at all.
- Cool and Unusual Punishment: Lelouch warns Issei to never put his sister's name in a lewd sentence, or he will put the only two bookstores in town that (illegally) sell porn to him out of business.
- Dead Fic: Last updated on June 12, 2017, after 8 chapters and a little over 50,000 words.
- Deadpan Snarker: Lelouch, naturally.Rias: And when devils take an interest in humans, it usually ends in only one of three ways.
Koneko: Peerage, Contract, Death.
Akeno: Or a steamy night of passion.
Lelouch: Three ways. None of which appeal to me very much, if at all. - Did We Just Have Tea with Cthulhu?: Ajuka, one of the Four Great Satans, occasionally teleports to Lelouch's place to have a chat over coffee and a game of chess.
- Dramatic Irony: When Sona accepted to gamble over a game of chess against Lelouch, Code Geass fans probably begun chuckling because they know he's the best there's at it. D×D readers, however, laughed even harder because defeating Sona at chess is her personal Engagement Challenge, something that Lelouch only learned when Serafall saw the board asked Sona if she was getting married.
- Entertainingly Wrong:
- Before finding out about the supernatural, Lelouch wondered how come someone with a history of perverted incident such as Issei's never got expelled or even suspended for it so far. Noticing the way Rias pays attention to him and her friendship with the influential Student Council President Sona "Shitori", Lelouch guessed that Rias liked him and was pulling strings to keep him in the school.
- Rias arrives to the conclusion that Lelouch's interest in the Evil Pieces comes from the fact they can (sorta) revive the dead and that the apparent orphan might want to use them to bring his parents back to life.
- Foil: Lelouch and Akeno. The former is an always proper and polite Celibate Hero, the latter is, well, Akeno.
- For Want Of A Nail:
- Thanks to Lelouch's unexpected intervention during the first fight between Freed Sellzen and the Occult Research Club, they managed to the defeat the stray exorcist right there and then. Without him, Valper Galilei lacked a proper wielder for the stolen pieces of Excalibur, forcing him to alter his plans.
- It seems Lelouch caught Akeno's eye before Issei could make much of an impression on her. It's pretty telling that, when Issei's Intimate Healing for his arm is mentioned, only Rias' name pops up as the one removing the excess draconic energy from it.
- Full-Name Ultimatum: Issei gets one when he was about to guess how a sister of Lelouch would look like. Being this Issei, it doesn't take a genius to guess how his hypothetical description of Nunnally would go.
- I Always Wanted to Say That: When Lelouch shows Rias' Peerage his gambling winnings for the night in order to prove he was saying the truth, Issei asks him for permission to borrow a wad of money. He then thumbs through the bills and take a sniff from them like a movie character after successfully completing The Caper.
- Instant Fan Club: Just like in Ashford Academy, Lelouch becomes incredible popular with the ladies in Kuoh Academy, if not even more so because it just recently became co-ed and girls greatly outnumber guys. And speaking of guys, it turns out his fan club has them too.
- Irony: Lelouch remarks on the bitter irony of arriving to a world (seemingly) as peaceful as the one he wanted to build for Nunnally, but without anyone to share it with.
- Lesser of Two Evils: After Issei unthinkingly let other Devils know that Lelouch helped to come up with a plan for Issei to defeat Riser, Lelouch was left with two options: weather the storm of questions that the attendees to the party had for him, or quickly escape to the dance floor by asking Akeno of all people to dance. Let's just say he didn't like giving her the satisfaction.
- Newhart Phonecall: Rias received a phone call from Sona late at night when she and her Peerage were at Lelouch's place after the events of her engagement party to Riser. Lelouch only hears Rias' side of the conversation, but it's pretty telling when she was to put the phone away from her ear when she says where she is and then hurryingly explains to Sona that her Peerage is there too.
- Non-Action Guy: Lelouch is passable good with a gun and nothing else in a fight, yet he insists in meddling with the supernatural. This is one of the reason why Sona offered him Peerage, and at his refusal, she taught him a bit of human magic.
- Ontological Mystery: Lelouch appears in D×D!Japan right after his death at the end of Code Geass completely unharmed and lacking his Hypnotic Eyes without any explanation of how that happened.
- Pair the Smart Ones: Serafall likes Lelouch×Sona, and somehow finds their I Know You Know I Know banter romantic.
- Popcultural Osmosis Failure: Issei and co. (sans Asia) couldn't believe Lelouch had no idea what Dragon Ball was. Justified because Lelouch comes from an entirely different world with a different popular culture.
- Spanner in the Works: Lelouch's contribution to the fight between Freed Sellzen and Kiba, Koneko, and Issei at the abandoned church was minimal, but the sheer improbability of a seemingly Ordinary High-School Student carrying a gun in Japan of all places caught the exorcist so badly off-guard that it gave Kiba the opening he needed to finish him off right then and there.
- Taught by Experience: Lelouch really knew what he was talking about when he subtly warns Kiba about the dangers of blindly seeking revenge, particularly the risk of losing what's important to his present self for the sake of avenging a wrong done to him in the past.
- The Tease: Once Lelouch got closer to the Occult Research Club, Akeno took his nonchalance toward the opposite sex as a challenge and made a hobby out of trying to get a reaction out of him through double-entendre and creative euphemisms.
- Threshold Guardians: Rias and Sona want to stop Lelouch from getting involved with the supernatural for his own safety, but he played his Batman Gambits and Politeness Judo just right so that they aren't willing to use force to do it. Instead, Lelouch challenges Sona to a game of chess for more information if he wins, and Sona takes the opportunity to make him promise to go back to his normal life if she wins. Of course, for his sake and the plot's, he doesn't lose that match.
- Tragic Dropout: Lampshaded. Lelouch dryly notices one day that he achieved actual world domination without ever finishing high school, so he decides to do his senior year and get his diploma pretty much on a whim. Fate made it so he picked Kuoh Academy of all places to do it, kickstarting the plot.
- Undead Tax Exemption: Averted. Lelouch appears without a dime to his name in D×D world, which is particularly ironic after he literally ruled his world. He makes do through gambling at first, but casinos quickly wise-up and firmly, if politely, begin to turn him away. He then switches to illegal gambling, but things soon get dangerous to the point he begins to carry a gun for protection and eventually he decides to lay low for a while. This is part of the reason he enrolls in Kuoh Academy.
- Uptight Loves Wild: Sona and Lelouch. As the responsible Student Council President, she's trying to get him to stop gambling and once even set him up for a part-time job under Ajuka because she considered that Lelouch was in need of "honest work".
- Weak, but Skilled: Lelouch is not a strong magic user by any means, but he learns fast and is very, very good at using simple spells in creative ways. For example, a minor illusion and a silence spell is was all it took for him to recover the two Excaliburs from Galilei and kill the guy.
- You Remind Me of X:
- Asia is so infallibly kind and nice to be with that she reminds Lelouch of his sister Nunnally.
- The small, quiet and occasionally blunt Koneko reminds Lelouch of the Knight of Six, Anya Alstreim.
- Freed's Ax-Craziness brought Mao back to Lelouch's mind. Channeling what he remembered of the mind reader's personality allowed him to impersonate the late exorcist.
