Sheilder - Mash Kyrielight- The Shielder Class Servant of Ritsuka Fujimaru. She is quite excited and motivated after hearing the details of the singularity from Saint Germaine upon arriving in 1851 due to being an fan of mystery novels like the
Sherlock Holmes series. Though she is rather apprehensive after Holme's "betrayal" of Chaldea during the tail end of the Human Order Revision. Since Holmes didn't join the Alien God and left rather abruptly after barely helping, his whereabouts are still unknown. Mash is one of the first to suspect Spring-Heeled Jack of not being what they seem. She later helpes piece together the true nature of all the seemingly disconnected factions vying for the OOPArts.
Kadoc Zemlupus- Formerly one of the Crypters, he survived the Human Order Revision and reluctantly helps Chaldea, hoping to prove himself, though he doesn't state so out loud. The Association's challenge to Chaldea seems to have sparked some conviction in him, albeit causing him to charge recklessly into battle during the Singularity. He ends up leading the raid on Elysium's Hideout and was the first one to encounter Spring-Heeled Jack.
Moon Cancer - Schrodinger's CatOlga-Marie Animusphere (Pseudo-Servant) A vessel for the Director's Soul trapped within the CHALDEA simulation during the events of Singularity F. It was created and snuck its way into the Summoning System, though who was responsible for this is unknown. Since none of the staff have confirmed involvement, and Schrodinger's Cat herself isn't sure, the most likely culprit is the Foreigner of the End, who tagged along on the Storm Boarder all the way back to Chaldea HQ prior to the restoration of Earth's bleached texture. Schrodinger's Cat is capable of existing in multiple places at once as long as she isn't being observed and although limited by time and degree of influence or reach depending on where she goes, this ability's interpretation of "a location where someone/something can manifest" is quite vague.
Assassin - Giacomo Girolamo Casanova: One of the Servants summoned by the Counter Force to protect the OOPArts. He ends up contracting with Kadoc after their first encounter after his eccentric and affable personality reminds Kadoc of his former ally, Scandinavia Peperoncino. Giacomo introduces himself as a cultured cosmopolitan, man of romance, genius inventor, and apparently a secret agent. Although, it is hard to tell where truth and embelishment ends with him. He is part of the Great Exhibition's management commitee and runs a small exhibit for ancient artifacts in order to gather information on the OOPArts.
Rider - Henry Avery:The “King of Pirates” who was one of the few successful pirates to peacefully retire as well as the founder of the anarchist pirate utopia, Libertalia. He and Casanova were summoned at the start of the World Fair, in early May and have the spent the time hunting down the OOPArts. They have had run ins with Elysium and initially attack the Chaldea Team, believing them to be enemies as well. Thus, Henry is carefree and freedom-loving to the extreme. He wishes to stop what he and Casanova have come to call the Advent Order Usurpation as he does not wish a single person or group to control the outcome of the future, no matter how prosperous it is.
Foreigner - H.G. Wells: The “Father of Science Fiction” has taken on the form of the infamous “Time Traveler” and his enigmatic machine. He is investigating the mysterious time machine that appeared somewhere in the city. Chaldea first encounters him when they visit the mysterious workshop in Trafalgar Square. It seems like the rumors surrounding the noises and lights from his experiments were muddled alongside the stories of Carter Aldoa's showcasing of futuristic technology to create the image of the enigmatic "Wizard of Trafalgar Square".
■■■■■After Singularity A begins collapsing, Wells accompanies Chaldea back to the present using his Time Machine, dragging a determined Casanova with them. With the help of Schrodinger's CatOlga Marie Animusphere, they manage to adjust the Rayshifting system for Time Travel to the future by locking on to the energy released by the temporal anomalies created by the OOPArts.
Archer - Nikola Tesla: The famous inventor and electrical engineer. He was summoned to this era to investigate the Time Machine and the temporal anomalies directly. He acts similar to a crazed conspiracy theorist in regards to the mysterious “Wizard of Trafalgar Square”, having gathered clues about the wizard's true motives relentlessly. He appears after the first break in at the Crystal Palace.
■■■■■While Tesla's theory ends up containing several mistakes and his conclusions seem far fetched, his overall theory about the Wizard of Trafalgar Square's true goal of using the OOPArts to alter the course of humanity's future ends up being true. With Mash's help, the pair figure out the that Arsene Lupin's Master is working with the Wizard, who in turn intend to collaborate with Elysium.
Alter Ego - Count of Saint Germaine (Living Person?): A lord of the Clock Tower from the year 1851 and the correspondent ensuring that Chaldea is doing their jobs properly. Despite the Clock Tower of the presents initial attempts to sway him into collaborating with them to some control over the Chaldea Security Organization, Saint Germaine refuses and instead helps out the Chaldea Security Organization in an honest fashion while still overseeing their capabilities impartially. He is an enigmatic and mysterious fellow of unknown origins. He seems to have just popped up among the mages of the Clock Tower one day without warning, making quick connections and an over all strange impression. He is versed in many things both magic and mundane and is rumored to have been present for many events in European History in the past. It is unknown whether the Saint Germaine is a living human, some discreet Time Traveller, or a servant summoned by the Counter Force.
