Literally, it’s a class, where those who used to be assassins or the spirits that have the anecdotes regarding assassination, belong to.

Actually, they are lowest in the battle status among all the classes so they are the weakest when it comes to a direct combat.

On the contrary, though, they do have a skill, specialized with covert operation. They are skillful at getting rid of battles by assassinating their masters (hosts), instead of a direct combat between servants.

She appears for the first time in Fate/Grand Order.

She was the boss that governed the Oni (demons) during the Heian period. (There are various theories but) one of them is that she is one of the “Japan’s Three Great Monsters” with powerful strength. Just like Oni appearing in a Japanese fairy tale, her personality is whimsy and she takes actions only “if it’s fun.” Among all the Oni, she has the highest combat strength. While she is sometimes mischievous, she tends to get involved with those who she likes so much.

Personally, I want to her be chosen as a swimsuit servant in 2021. (Her usual outfit is like a swimsuit, though……)

She appears for the first time in Fate/Grand Order.

She is the God of Love from Indian mythology. She used to have mission in her mind, where she would make Shiva and Parvati (both God) be deeply in love with each other, using an arrow of love, so she can save the world’s crisis but…… When she accepts to summon, she borrows a girl’s figure, which is somehow familiar to us. She is basically very lethargic and has no interests in anything, but also is sarcastic and self-deprecating.

She appears for the first time in Fate/Apocrypha.

She is a worldly-known serial killer, which startled all over England. Her true nature is that of “a collection of wraiths born from the aborted children of prostitutes”. (Jack the Ripper is a unique spirit in England with so many anecdotes, and both sexes and figures change depending on a master she summons or the era.) This Jack, as you can see, is pure and has a childlike cheerful personality but……

She appears for the first time in Fate/Grand Order.

She is famous as a yokai haunted in Himeji castle located in Hyogo Prefecture. She used to be a God of mountain called Osakabe-Yama, however, in time, she has settled in the keep of Himeji Castle. She was a “fox” yokai before but was summoned as a bat-motif servant after all. She is a shut-in type otaku girl but it doesn’t mean she dislikes humans. She tends to be a little sneaky but basically a good girl.

She is originally a character who appeared in the April Fool project held by TYPE-MOON in 2013.

However, she was somehow implemented in Fate/Grand Order. Incredible.

She tasked herself in eliminating Saber-class heroines which have been increasing in numbers, but, she has never made it yet. She has the same face, voice and sacred sword (Excalibur) as Artoria Pendragon. Her true color is unknown and nobody would try to reveal it, either.

She appears for the first time in Fate/Grand Order.

She is a ninja who has played an active role in the Edo period. There are legends about “how Katou Danzou operated puppets, karakuri dolls,” but those are legends derived from the fact that “Katou Danzou herself was a karakuri doll.” Therefore, she is actually a robot. Her personality is incredibly serious and loyal to her master. She is sometimes so serious that she tends to be a little off, which is one of her attractions.

She appears for the first time in Fate/Grand Order.

She is a female spy active in the underworld. She may as well have been the most wondrous individual among her kind, getting rid of a number of opponents’ shogun until the day she was executed as a spy. Although Servants from Assassin-class are skillful at Presence Concealment, she played an active role as infiltrating, while standing out, therefore, she is not skillful at spying. While lacking of attacking ability, she is excellent at attracting and weakening enemies. She is a cheerful and kind older-sister-type girl but has a strong will inside of her at the same time.

Personally, I love a commercial when she appeared in Salem in Chapter 1.5. So cute.

She appears for the first time in Fate/Prototype.

She is known as a “poison girl,” a master of poison, handing down anecdotes throughout the world such as India before Christ. Her body is filled with poisons and she can kill anybody who she touches even if they are the heroes. While she fights, making use of powerful poisons, she cannot control herself and cannot even touch those who she is very close to, either. The players (masters) from Fate/Grand Order are immune to any kind of poisons so they are the rare and special ones whom she can touch.
