Benders, magicians, dragons, Mobians and dragon-riders all live in hiding amongst regular humans. The momosu are [the monmosu] in fact a sub-species [the monmosu] of the Mobians in this fic.

The Taragayens are [the Taragayens] also hedgehog mobians [Sonic franchise] in this story, unbeknownst to their [the Taragayen's] loyal subjects of the Brittanian empire and the native inhabitants of the Brittanian colonial empire

The Kingdoms of Westeros  [Game of Thrones/A Song of Ice and Fire] are [the Kingdoms of Westeros] instead sub-kingdoms [the Kingdoms of Westeros] inside the Holy Brittanian Empire. The Crownlands  [Game of Thrones/A Song of Ice and Fire] are the US state of New England, Jamaica and the area surrounding Toronto, with Brittania's capitol, Pendragon [Code Geass] being located in Kingston, Jamaica, the House of Stark-ruled North  [Game of Thrones/A Song of Ice and Fire] being [the North] Canada,  the Kingdom of the Isles and the Rivers being  the rest of the Caribbean, the Kingdom of Mountain and Vale being the pre-1947 British Raj consisting of India, Pakistan and Burma, the Kingdom of the Rock is based in Gibraltar but [the Kingdom of the Rock] controls Egypt and the Sudan, the Storm Kingdom [Game of Thrones/A Song of Ice and Fire] consists [the Storm Kingdom] of the American States that were part of the Confederacy, the Kingdom of the Reach [Game of Thrones/A Song of Ice and Fire] consists [the Kingdom of the Reach] of Oceania [Australia and New Zealand], and the Principality of Dorne is [Dorne] based in Corsica, but [Dorne] rules over the Arab peninsula.

A more successful NSDAP-ruled Greater Germanic Empire/Greater German Realm/"Nazi Germany" which [this story's version of Greater Germany] managed to [this story's version of Greater Germany] conquer the Western Allies due to Brittania's non-intervention in either world war in the timeline of this story and [this story's version of Greater Germany] subsequently use the resources of the conquered Western allies to [this story's version of Greater Germany] prepare for the inevitable confrontation with the Soviet Union, which [the invasion of the USSR] it [this story's version of Greater Germany] succeded in, [this story's version of Greater Germany] conquering all of Russia up to the Urals by 1942. After the fall of the Soviets, this story's version of Greater Germany forms the real-life European Union as Europa-United [Code Geass]. 

The infamous Führer und Reichskanzler [Leader and Realm Chancellor |Führer und Reichskanzler|] of Greater Germany, Adolf Schicklgruber, [Adolf in this story] is/was in fact the openly gay nephew [Adolf in this story] of the last Kaiser [Emperor] pre-Weimar Germany, Willhelm II, who [Willhelm II in this story] had [Willhelm in this story] chosen Adolf as his [Willhelm II's in this story's] heir after the death of his [Adolf's] father and Willhelm II's preferred successor, Alois, in [when Alois died] 1903. Adolf was [Adolf in this story] in fact born [Adolf in this story] in Gippsland, Australia to the then-Crown Prince Alois and his [Alois'] wife and thus Adolf's mother, Klara. Alois was [Alois] also born [Alois] in Gippsland, Australia as well. Adolf's lover and [Adolf's] imperial consort was the eldest son of pre-WW1 Austria's last Kaiser, Franz Josef, Sebastian von Habsburg, who [Sebastian] resembled his [Sebastian's] close relative, Paul von Hindenburg greatly. 

Adolf and Sebastian are/were Germany's imperial couple, with the 1938 Anschluss of Austria into Germany simply being the result of their [Adolf's and Sebastian's] marriage to each other [Adolf and Sebastian]

 The NSADP in this story started off as a monarchist political organization and political party in Germany dedicated to supporting Adolf during the years of the Weimar Republic. 

Adolf was [Adolf in this story] officially [Adolf in this story] coronated as the next German Kaiser [Adolf in this story] after Wilhelm II on 1941, [Adolf in this story] being known as Kaiser Adolf I. Due to his [Adolf's in this story's] sperm being [Adolf's in this story's] sperm stolen from him and [Adolf's sperm in this story] being used to impregnate the daughter of Soviet dictator Josef Stalin, who [Stalin in this story] was [Stalin in this story] in fact the son [Stalin in this story] of the last pre-Soviet Russian Empress, Anatasia, with neither man [Stalin and or/Adolf in this story] of course being aware of this, Adolf ended up having quite a few descendants, with some even marrying into Sebastian's bloodline despite [Adolf] being gay. 

Europa United is [Europa United] also known as the Zepharos Empire [Seikoku no Doragunā]. 


 The fastest thing alive, the blue-furred, white-belly furred, green-eyed supersonic speed-having, laid back and relaxed but also determined and focused psychic anthropomorphic hedgehog Maurice Ogilvie Wentworth [Sonic the Hedgehog comics], [Maurice] better known to the public as "Sonic the Hedgehog", [Sonic] replaces [whom Sonic replaces in this story] the current Brittanian crown prince in canon Code Geass, the violet-haired, violet-eyed, tall, slender and lean but not athletically gifted, immensely intelligent and academically gifted, brooding and reserved but also kind and caring with an immense sister complex Lelouch vii Brittania [Code Geass], as well as the white-haired, gray-eyed former crown prince of the Arcadia Empire [Undefeated Bahamut Chronicle], Lux Arcadia [Undefeated Bahamut Chronicle] and the brown-haired, amber-eyed, tall and slender, steadfast and determined young man, Ash Blake [Seikoku no Doragunā], with his [Sonic's] parents, the now-robian [cyborg Mobian |robian|] with a blue and white color scheme, red-eyed Jules Wentworth [Sonic the Hedgehog comics] and his [Jules'] wife and thus Sonic's mother, the now-robian, lavender-furred, white-skinned, blonde-haired, blue-eyed Bernadotte Wentworth [Sonic the Hedgehog], [Jules and Bernadotte] replacing the current Emperor of Brittania in canon Code Geass, Charles zii Brittania [Code Geass] along with the Crown Prince of the Taragayen-ruled Kingdom of Westeros in canon GOT/ASOIAF before the end of Taragayen rule, Rhaegar Taragayen [GOT/ASOAF], Charles' Imperial Consort before her death, Marianne Lamperouge [Code Geass] and Rhaegar's second wife before his [Rhaegar's] death, Lyanna Stark [GOT/ASOIAF]. Jules and Bernadotte have Charles' and Marianne's canonical status of being the current reigning Brittanian Emperor and Empress with Sonic replacing Lelouch as the current Brittanian Crown Prince. Bernadotte also has Lyanna's status of being the current heiress to the House of Stark. Sonic's main human form is a green-eyed version of Ash's human appearance, however he [Sonic] also uses a more lean and muscular version of Lelouch's canon appearance as a secondary human form

Sonic also replaces the Japanese black-haired, purple-eyed, tall, slender and muscular, skilled swordsman and magic-using teenage boy and ex-street kid Karasuki Ryū [Seirei Gensōki] who [Ryū] is [Ryū] the reincarnation [Ryū] of [who Ryū's past life was] the tall, slender and muscular, kind and loyal swordsman-in-training and Japanese noble heir  Amakawa Haruto [Seirei Gensōki] who [Haruto] was [Haruto] killed [Haruto] in a bus accident in OTL Japan on OTL Earth while [Haruto] going home from college and [Haruto] was [Haruto] subsequently reincarnated [Haruto] as Ryū [Seirei Gensōki], [Sonic replacing Ryū] as Haruto's reincarnation due to [Sonic in this story] having a blood transfusion as an infant from a then-dying young Ryū, which [the blood transfusion] gave him [Sonic in this story] Haruto's memories, skills and abilities along with the powers and abilities of  Ryū, and [Sonic replacing] Zero no Tsukaima's protagonist, the black-haired, blue-eyed, short and slender but also muscular teenage Japanese Hiraga Saito [Zero no Tsukaima], Saito being his [Haruto's] middle name in this fic as well as having Saito's status of Gandálfr [Zero no Tsukaima], which essentially means he [Saito] gains absolute mastery of any item meant for combat when he [Saito] touches and [Saito] subsequently weilds it, even artillery cannons and fighter aircraft, [Saito] also gaining heightened strength, agility, endurance, and reflexes as well as mastery over scientific application of technology to be included in using any weapon due to his [Saito's] status as Gandálfr. Sonic in this story also replaces the short, slender and lean, purple-haired, blue eyed, naive and somewhat delusional but also intellectually gifted and kind young boy training to be a Hero [Monmusume Kuesto! & Musume Hyakka Jiten] with a dream of coexistence between humans and monmosu [Musume Hyakka Jiten & Monmusume Kuesto!] who is unknowingly a Nephilim [fallen angel-human hybrid |Nephilim|] Luka Hein [Monmusume Kuesto!], [Sonic in this story] having Luka's Nephilim nature and his [Luka's] dream of coexistence between humans and monmosu [Musume Hyakka Jiten & Monmusume Kuesto!]. 

The revolt of Robert Baratheon against the Taragayens, backed by House Lannister [GOT/ASOIAF] still occurs but the now-elderly, short, muscular, fat, immensely brilliant and academically gifted with a skill for inventing and making things Russian mad scientist Dr. Ivo Robotnik, [Ivo] better known as [Ivo's current alias] "Dr. Eggman", [Eggman] after [Eggman] rising through the ranks of the anti-Taragayen rebels due to his [Eggman's] intellect, tactical ability and skill with invention, [Eggman] seizes control of most of the revolutionary army and the revolutionary government, [Eggman] proclaiming the formation of the technocratic fascist machine-supremacist imperial stratocracy of the Eggman Empire [Sonic the Hedgehog comics] and [Eggman] declaring war on both Robert and the Taragayens. 

 The development of the hightly explosive mineral known as Sakuraide-powered, towering humanoid war mechs known as Knightmare Frames [Code Geass] by the Brittanian noble house of Ashford occurs during the three-way civil war in Brittania, with all three factions [Robert's faction, the Eggman Empire and the Taragayen loyalists] using them [the Knightmare Frames] in combat. 

Robert manages to [Robert] get de-facto control over the Kingdoms of Westeros, [Robert] proclaiming himself [Robert] "King of the Seven Kingdoms" but [Robert] is [Robert] viewed by the international community as a usurper and illegitimate ruler, with Brittania being embroiled in costly, unecessary wars against the Soviets, in Indochina, the surviving Tokugawa shogunate and against the remnants of the Soviets and Turkey, while the power clique that had gotten Robert into power profits immensely and the common Brittanian suffers immensely  as a result of this

 Jules is [Jules] mortally wounded while [Jules] fighting against Robert's forces and [Jules] left for dead in the chaos in the battle, [Jules] being [Jules] found by Eggman's mechanical forces and [Jules] transformed into a robian after that. Bernadotte is [Bernadotte] transformed into a robian after [Bernadotte] giving birth to Sonic and [Bernadotte] believed to be dead, with the then-newborn Sonic being [the then-newborn Sonic] taken in by anti-Eggman and anti-Robert forces within Brittania, the so-called Freedom Fighters [Sonic the Hedgehog comics], [Sonic] being clueless as to who he [Sonic] really is until Robert dies while [Robert] hunting boar and Eggman being [Eggman] killed by [Eggman] a Nationalist Chinese sleeper cell in his [Eggman's] inner circle and the Freedom Fighters manage to [the Freedom Fighters] take control of the Kingdoms of Westeros after both Robert's and Eggman's deaths, [the Freedom Fighters] making Jules' older brother, the blue-furred, white-belly-furred black-eyed, immensely intelligent, academically gifted, skilled inventor and mad scientist Charles Wentworth [Sonic the Hedgehog comics] into the Imperial Regent for Brittania as the Freedom Fighters search for the Emperor and Empress [Jules and Bernadotte], who [Jules and Bernadotte] are [Jules and Bernadotte] found in a still working Eggman factory and [Jules and Bernadotte] subsequently freed [Jules and Bernadotte] from Eggman's mind control, [Jules and Bernadotte] being [Jules and Bernadotte] restored [Jules and Bernadotte] to their [Jules' and Bernadotte's] rightful positions, although Sonic is rather embarasssed when he [Sonic] is [Sonic] revealed [Sonic] to be the true Brittanian Crown Prince [Sonic]. 

The blonde-furred, with orange markings around her eyes, head, and on the tip of her ears with a white muzzle and light pink inner ears, chestnut brown eyes, thick, soft, white hair, large, looped ears that hang behind her head, small, brown and shiny nose and circular, fluffy tail, short and petite but also secretly buxom young anthropomorphic rabbit Cream [Sonic the Hedgehog], who [Cream in this story] replaces Lelouch's] younger full sister, the blonde-haired, violet-eyed, currently blind and paralyzed tall, slender and petite, kind and loving but also very possessive, brilliant and somewhat clueless with an immense brother complex, Nunnally vi Brittania [Code Geass], along with  the blonde-haired, blue-eyed, short, slender and petite, shy, reserved and soft-spoken but publicly strong, stern and also being very competitive princess Silvia Lautreamont  [Seikoku no Doragunā] and the short, slender and petite but also curvy and very buxom, proud and haughty but also kind and caring blonde-haired, green-eyed noble heiress, Rinslet Laurenfrost [Seirei Tsukai no Bureidodansu], [Cream in this story] having Rinslet's ice manipulating lupine contracted spirit that can transform into a bow, Fenrir  [Seirei Tsukai no Bureidodansu], [Cream] is [Cream] discovered [Cream] to be Sonic's younger half-sister [Cream]. As a result of this Jules is [Jules] forced to make Cream into a Princess of Brittania and her [Cream's] mother, Vanillia, becomes Jules' third wife after Bernadotte. Cream's crush on Sonic, which [Cream's crush on Sonic] she [Cream] had [Cream] kept hidden, [Cream's crush on Sonic] becomes blatant after this with the young Princess [Cream] becoming quite clingly [Cream] around him [Sonic] although he [Sonic] is [Sonic] of course [Sonic] clueless about this. Cream has a combination of Nunnally's, Rinslet's and Silvia's features in her [Cream's] human form

The oldest child of Rhaegar and his [Rhaegar's] first wife in canon Game of Thrones/A Song of Ice and Fire Elia Martel, the black-haired, blue-eyed, olive-skinned, mischevious and hyperactive but also loving and kind, Rhaenys Targaryen, who [Rhaenys] is [Rhaenys] the daughter [Rhaenys] of Jules and Elia in this story, [Rhaenys] who [Rhaenys] replaces one of Charles' oldest daughters, the fuchsia-haired, blue-eyed, tall, slender and buxom, determined and steadfast with a skill at military strategy, ultra-patriotic and cold-blooded Cornelia li Brittania [Code Geass] and [Rhaenys in this story] has her [Cornelia's] body build and [Cornelia's] personality, [Rhaenys in this story] isn't killed by Robert's hitmen due to her [Rhaenys in this story]  escaping to the now colonized by Brittania surviving Tokugawa shogunate, [the now-colonized by Brittania surviving Tokugawa shogunate] now known as Area 11 with the help of a sympathetic servant.  Rhaenys' hedgehog form in this story has black fur, white belly fur with fuchsia hair and blue eyes along with a tall, buxom build. 

Rhaenys in this story in this story lives in Area 11 under the disguise of the dark-purple-haired, blue-eyed, sharp-tongued, blunt, harsh and somewhat emotional but sincere and cheerful rich human Japanese girl Senjōgahara Hitagi [Bakemonogatari], [Rhaenys in this story] returning to Brittania under another alias from time to time to [Rhaenys in this story] fight in the Freedom Fighters' ranks as she [Rhaenys in this story] grows. After the death of both Eggman and Robert, Hitagi returns to Brittania under her [Rhaenys' in this story's] real name and [Rhaenys in this story] reunites with her [Rhaenys' in this story's] father [Jules in this story], [Rhaenys in this story] taking her [Rhaenys' in this story's] rightful position as the current Brittanian Crown Princess [Rhaenys in this story]. 

After Rhaenys' in this story's return, Sonic's mechanical double created by Dr. Eggman, the blue-coloured, red-eyed combat android known as Metal Sonic [Sonic the Hedgehog] is [Metal Sonic] sent [Metal Sonic] to [Metal Sonic] retrieve one of the powerful gems filled with the primordial force known as Chaos Energy, the Chaos Emeralds [Sonic the Hedgehog] from a lab, only for it [Metal Sonic] to [Metal Sonic] get trapped in a deroboticiser designed to make robians into mobians once more, which [the deroboticser] reacts badly to its [Metal Sonic's] presence, [the deroboticiser] exploding and [the deroboticser's explosion] transforming Metal Sonic into a female robian with a flesh and blood body and a metal endoskelton, with blue fur, white-belly fur, a buxom figure and green eyes like Sonic with no memories of her [the transformed Metal Sonic's] previous life and a deep admiration for Sonic with  all of Metal Sonic's powers and abilities who [the transformed Metal Sonic] believes that she [the transformed Metal Sonic] is [the transformed Metal Sonic's] Sonic's full little sister. The transformed Metal Sonic adores Sonic

This transformed Metal Sonic is [the transformed Metal Sonic] found [the transformed Metal Sonic] by a Freedom Fighters squad searching for any remains of Eggman's robotic army and [the transformed Metal Sonic] brought [the transformed Metal Sonic] to the Imperial Palace in Pendragon, [the transformed Metal Sonic] subsequently made a princess [the transformed Metal Sonic of Brittania by Jules. 

This transformed Metal Sonic replaces the tall, slender and petite but also curvy and buxom, black-haired and purple-eyed second princess of the Ordesian Empire [Seirei Tsukai no Bureidodansu], the soft-spoken, shy and reserved but also teasing and playful Fianna Ray Ordesia [Seirei Tsukai no Bureidodansu], [the transformed Metal Sonic replacing] the purple-haired, blue-eyed, tall, slender and petite, but also buxom and somewhat curvy, shy, reserved and soft-spoken, sickly fourth princess of the Kingdom of Lescarte [Musume Hyakka Jiten], Francisca Mistel [Musume Hyakka Jiten], [the transformed Metal Sonic] having her [Francisca's] first name as her [the transformed Metal Sonic's] first name but not her [Francisca's] sickness, [the transformed Metal Sonic in this story also replacing] the short, slender and petite, curvy and buxom, soft-spoken and reserved but also kind and caring Crown Princess of Tristian, Henrietta de Tristain [Zero no Tsukaima],  [The transformed Metal Sonic in this story] having her [ Henrietta's] first name as her [The transformed Metal Sonic's in this story's] middle name and  [The transformed Metal Sonic in this story] having her [Henrietta's] hair color when she  [The transformed Metal Sonic in this story] gets angry or  [The transformed Metal Sonic in this story] has any other dark emotion as well as  [The transformed Metal Sonic in this story] replacing [the other character whom The transformed Metal Sonic in this story replaces] the violet-haired, purple-haired, short, slender and petite but also curvy and buxom, weak-willed, shy and reserved but also incredibly smart, strong and obstinate  second princess of the canon  Beltrum Kingdom in canon Seirei Gensōki, Flora Beltrum [Seirei Gensōki], [the transformed Metal Sonic] having Fianna's apperance as her [the transformed Metal Sonic's] main human form. 

A series of raids conducted by the Freedom Fighters on surviving Eggman Empire bases lead to the rescue of a never-deployed supersolider project implemented by Eggman using a combination of Cybernetics and a manipulation of Jules and Bernadotte's DNA from a Eggman Empire lab, which [the supersolider project] turns out to be a light-brown haired, amber-eyed, short and slender human girl with the ability to switch into a brown-furred, white-belly furred, green-eyed hedgehog form named Linda Blake. Linda is [Linda] brought to the Imperial Palace and [Linda] subsequently adopted by Jules as his [Jules'] daughter, [Linda] becoming Marrybell mel Brittania [Code Geass]. Unbeknownst to everyone [at first] Linda is [Linda] in fact Ash's Pal [Seikoku no Doragunā] due to her [Linda] being [Linda] the reincarnation [Linda] of [Linda's past life] the pink-haired, red-eyed, short, slender and petite but also secretly curvy and buxom young dragoness girl in a human form Eco Aurora-Christa Pendragon Lena Anherusu-Ilya Roransu Liliane-Muriel-Octavia-Robertine de la Rosa Resuperansu van de Compostela Avalon [Seikoku no Doragunā], [Eco Aurora-Christa Pendragon Lena Anherusu-Ilya Roransu Liliane-Muriel-Octavia-Robertine de la Rosa Resuperansu van de Compostela Avalon] better known by her [Eco's Aurora's-Christa's Pendragon's Lena Anherusu's-Ilya's Roransu's Liliane's-Muriel's-Octavia's-Robertine's de la Rosa's Resuperansu's van de Compostela's Avalon's] first name [Eco], who [Eco] is [who Eco is] the imperial crown princess [Eco] of the entirely dragon-populated, now long gone Avalon Empire [Seikoku no Doragunā], [Linda being Eco's reincarnation] or rather, Eco's soul was transmigrated into the body of the girl that became Linda and later Marrybell. Despite her [Marrybell's] young physical and mental age she [Marrybell] is [Marrybell] good at strategy, tactics and planning and [Marrybell] becomes the commander [Marrybell] of Brittania's elite all-female anti-terrorism search-and-destroy armor unit within the Brittanian military with the job of suppressing terrorism throughout Brittania, the Glynda Knights [Code Geass]. 

Francisca and Marrybell become rather close to Sonic, [Francisca and Marrybell] loving him [Sonic] as more than a older brother [Sonic] just as much as Cream. 

The excerpt should focus on Sonic, in his [Sonic's] first human form and under Ash's name, [Sonic] trying to adjust to his [Sonic's] life at the all-ages private boarding school run by the Ashfords within Area 11, Ashford Academy [Code Geass] while [Sonic] trying to hide the fact that his [Sonic's] little sister [Marrybell] is [Marrybell] his [Sonic's] Pal [Seikoku no Doragunā] and [Sonic] also dealing with the fact that he [Sonic] is [Sonic] in fact royalty and [Sonic] his [Sonic’s] nation’s future Emperor, having a few flashbacks to the war against both Eggman and Robert and the victory of the Freedom Fighters over both [Eggman and Robert] as well as the fact that he [Sonic] has siblings [Cream, Francesca, Marrybell and Rhaenys in this story]. Sonic is [Sonic] also trying to [Sonic] hide the fact that he [Sonic] can [Sonic] pilot both IS units and Drag-Rides from the people around him [Sonic], which [Sonic’s Drag-Ride and IS unit piloting ability] he [Sonic] views as unimportant along with [Sonic hiding] Cream's presence from the students of Ashford Academy.
