Mosaic City

is a city in Japan in the World of Fate/Requiem. As the last place on Earth suitable for humans to live after the large Holy Grail War fourteen years prior, it is a city in which all citizens are granted a piece of the Holy Grail and summon Servants. It is the main setting of Fate/Requiem.
==Characteristics==
Mosaic City is comprised of the former wards of Tokyo, such as Shibuya, Shinjuku, and Akihabara. Each area is overseen by one of the Caren Series AIs. People can travel between districts of the city via train. The train tracks run over the water, and ruins of Tokyo from before the Grail War can be seen in the sea as the train passes by.Fate/Requiem Volume 2: Shinjuku the Nostalgic City - Chapter 11 In Mosaic City, the Stigmata Chitose Manazuru's final word is equal to the judgement of the Holy Grail. Her decisions cannot be overturned.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 2 
Mosaic City is safe inside a bounded field, but the world outside is a wasteland due to the destruction caused by World War III 14 years ago. Many drones left over from the war still litter both the land and sea, and will automatically attack vessels that get close. Mosaic City used to accept refugees escaping from the world outside, but over time seeing new people enter the city has become exceedingly rare.
Mosaic City's highest state of emergency is known as . Before Nzambi's attack on the Holy Grail Tournament, it had only ever been invoked once before. Its red is not the red of danger, but the red of Rome, of the proud battle standard of the Roman army, and their patron, Mars. When Code Crimson is invoked by a member of the Caren Series, Chitose Manazuru and Lucius Longinus arrive to defend the city.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 6
===Nightwatch===
Special agents called hunt Servants who break the rules of the Holy Grail and endanger civilians. Their job is to hunt down outsiders ill-suited to the city and expel them - or, if necessary, end their lives.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 7 They take orders from the Caren Series. It is not uncommon for the citizens to hold a grudge against members of the Nightwatch, and it's rare that they are ever thanked for doing their work.
People trusted by the Caren Series, such as members of the Nightwatch, can be given a special authority called . This gives them the ability to instantly jam or intercept any citizen of Mosaic City's communications. By making a chopping motion with her middle and index fingers, Makki was able to instantly cut Karin's phone connection, preventing her from making a call. Erice has had temporary access to this authority on certain missions.

===Akihabara===

RequiAkiba FGO.png|Coastal City Akihabara in Fate/Grand Order
 is the setting of volume 1 and where Erice Utsumi lives. While in the old world Akihabara was once a mecca for otaku culture, in the world of Fate/Requiem that was transformed by the Holy Grail, it has become a seaside resort city with many stores that sell magical trinkets. It also hosts the Holy Grail Tournament, a fighting sport between Servants. It was overseen by Caren Fujimura before her death. After her death, control was split equally among the other Carens.
====Erice's apartment====
Erice's apartment is located in a large abandoned department store. It used to be a maid café, but Erice repurposed it once she moved out of her grandmother's home. The inside is decorated in Victorian style with wooden floorboards, preserved unaltered from its former role as a maid café. Her apartment isn't for ease of living, but it has a bathroom and bedroom, more than sufficient for one person to live in comfortably. It has a small veranda in the bedroom, from which Erice can gaze at a small bit of ocean visible between the surrounding buildings.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 1
====Akibagabara Jyogakukan High School====
Called "Akijyo" for short. A prestigious young ladies' school which Rurihime attends.
====Akihabara Department Store====
Akihbara's shopping district is known locally as the Department Store, but that is just a name left over from the old world. The Department Store is comprised of innumerable tiny shops beneath an overpass. The surface floor is full of tourist-trap stores selling trinkets, decorations, and charms with very weak magecraft effects that can be activated by non-mages by using their Command Spells. From the perspective of an actual mage, the amateurish magecraft on display would probably cause derisive laughter.
Delving into deeper floors of the labyrinth, the atmosphere of the Department Store becomes seedier. Shops include those run by Caster-class Servants selling magical goods made from scratch, or charms made by tinkering with or tuning existing goods. The prices are extremely steep, and Erice stocks up on them from here for her Nightwatch duties. Hidden out of the way, behind an invisible bounded field that prevents spiritual beings like Servants from entering, is a shop selling summoning Catalysts.
====Akihabara Station====
The train station connecting Akihabara to the other wards of Mosaic City has a bustling plaza out front, where food trucks stop and many street performers play their music. There is a screen on a building that plays footage and advertisements for the Holy Grail Tournament.
====Bookshop Café Borges====
Bookshop Café Borges is a two-story coffee shop and one of Erice's favorite places to relax. The first floor holds the café itself, while the second floor has innumerable bookshelves crammed so tightly that it looks like the floors might give out, along with sofas and chairs for reading.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 3
====Borgia Siblings' hotel====
A cozy luxury hotel catered toward tourists, with an austere Renaissance-style lobby. The aging hotel manager is the Master of the Borgia Siblings, with the Borgias themselves employed as concierges, though they also tend to do most of the actual managing. Secretly, it is also a common visit for those involved in the criminal underworld, as the Borgias are very knowledgeable information brokers.
====Caren Fujimura's classroom====
Akihabara's management AI also runs a public history class that people of all ages can sign up for. Her classroom is located in one floor of a tall, multi-story building housing a variety of different public service facilities. The building is nestled a comfortable distance from downtown on the middle stratum, bordering a public park.
====Colosseum====
Akihabara's Colosseum, located on the outskirts of town near the sea, is designed in a Roman style. With four levels, it stands as tall as a skyscraper. It hosts the Holy Grail Tournament. The outer hall is an indoors, but large and airy, space that gently curves to match the shape of the building. Shops line the walls and screens show the action in the arena.
The Colosseum's seating is designed to siphon magical energy from the thousands of people in the audience, allowing for competitors in the Grail Tournament to fight at their best. It is the only place in Mosaic City where a Servant can easily and safely use their Noble Phantasm. Activating a Noble Phantasm anywhere else is highly challenging, often requiring a Command Spell, and using one could kill a Master from the magical energy drain unless attempted with extreme care.Fate/Requiem Volume 1: The Boy Among the Stars - Chapter 4
The Colosseum's arena is a huge rectangle, 200 meters long. It can transform into various environments; when holding a naval battle the arena split in half and folded in on itself to become a basin, then seawater pumped in from the ocean filled in the space and rocks emerged from underneath. Each seat in the audience has a floating semi-transparent screen that allows the spectators a clear view of the action. An invisible barrier around the arena prevents any stray attacks from hitting the audience.
====Kanda-myōjin====
 is a Shinto shrine that protects the weakest point in Akihabara's Ley Lines, serving as a counterpart to Yushima Tenmangū. Together the two perform essential duties in the city. It is dedicated to Ōkuninushi, Sukunabikona, and Taira no Masakado.Fate/Grand Order Collaboration Event: Board Game Apocalypse - Section 2: The Lost "Reaper"
====Kanda River====
The is a harbor that opens up to the ocean, with various boats moored at the docks. Waterborne buses sail the river during the daytime.Fate/Requiem Volume 1: The Boy Among the Stars - Prologue Despite the name, it bears little resemblance to the Kanda River of the old world. In the world "After" the Holy Grail War, it is more like a canal through which sea water flows.
====Kykeon Stock Aeaea====
A restaurant chain run by Circe and her Master with locations all across Mosaic City. There are two in Akihabara, but the one in the Colosseum had to be closed indefinitely after Nzambi's attack.
====Yushima Tenmangū====
 is a Shinto shrine run by Rurihime's family, dedicated to , the kami of learning. While in the old world the shrine was part of Tokyo's ward which neighbors Akihabara, when the Grail restructured the city it was incorporated into Akihabara and now sits at the district's northern border, near the sea. It receives many visitors seeking to pray to the kami, and has shops like a tempura manju stall where Ushiwakamaru works.
The shrine is an important location for Mosaic City's Ley Lines, with the chief priest of the shrine given the job of maintaining and preserving them. If something were to happen to the shrine, the bounded field around Akihabara would collapse and the district's Servants which rely on the Ley Lines to receive magical energy from the Grail would dysfunction.Fate/Requiem Volume 2: Shinjuku the Nostalgic City - Chapter 10
====Umebayashi Park====
Umebayashi Park is a park located by the sea, in front of Yushima Tenmangū. Except for the bright white sand and clear blue sea, it looks like it came right out of the Edo Period.
===Shinjuku===
Shinjuku Requiem.jpg|Nostalgic City Shinjuku
RequiShinjuku FGO.png|Nostalgic City Shinjuku in Fate/Grand Order
 is the setting of volume 2 and where Chitose Manazuru lives, as well as where Erice was raised. Its architecture is a recreation of 1920s Japan. A city with a three-storied structure that was reconstructed in the same way as Akihabara. Each block is called with the name of a town, such as Hanazono, Tsunohazu and Kashiwagi. Having the largest population, it is the current capital of Mosaic City. It is overseen by Caren Himuro.
====Chitose's home====
Chitose Manazuru's house is located in the Hanazono block, in Shinjuku's upper level.
====Kabukichō====
 is Shinjuku's red light district. A shady street located behind the kabuki theater, marked by the dazzling glare of neon signs. The city's upper level above the street blocks out the sunlight, covering it in a gloom that makes it look like sunset is approaching. The lighting is intentional, meant to be a fitting mood for the area that could suck in exhausted adults with the allure of comfort both day and night. The street smells of tobacco and drugs, accompanied by the sounds of music, drinking, and games. The area is home to a yakuza boss.
====Reijinza Hall====
Reijinza Hall is a café and hostess bar in Kabukichō, owned by Caren Himuro and run by Makki. Mata Hari and Annie Oakley are waitresses here.
====Shinjuku Central Station====
Shinjuku's train station overflows with people, mostly businessmen. It is located in Tsunohazu, Shinjuku's widest block. Shaped like a half-circle with multiple levels, the station is Mosaic City's central hub and its trains connect to all the districts. From here people can also board a tram that wraps all around Shinjuku like a net. There is a fruit parlor in the station's front.
===Shibuya===
 is where Karin lives.
====Caren's Chinese restaurant====
Shibuya's Caren Series AI runs a Chinese restaurant.
===Tama===
 is a residential district that carries the left-over atmosphere of a Pre-War commuter town, a vast town rich with nature, abundant with average citizens and students. It is managed by Caren Gotou.
Five years before the start of the story Tama was where Louis XVII and his Master began their mass murders that eventually spread across Mosaic City.Fate/Requiem Volume 2: Shinjuku the Nostalgic City - Chapter 9
====Alexandria====
A library where Euclid works. It has a statue of Iskandar.
