A Master apprentice dispatched from the outside. She flatters everyone with a constant smile, but her personality is the absolute worst. She views Servants as mere "stats" or "tools to make her stand out," and she tries to poach Servants from other factions whenever she gets the chance. She acts like a total "ぶりっ子" (fake-cute) around male Servants and handsome men. While she superficially flatters female Servants, she secretly looks down on them, thinking it's "vulgar for a woman to fight as a Heroic Spirit." She has already formed contracts with several Servants.

A female Servant. She has blonde hair, green eyes, and a dignified bearing. In truth, she loves to eat. Also known as the King of Knights, King Arthur. Looking at the Knights of the Round Table and their eccentric behavior, she wonders if she raised them wrong. First person: I (polite, formal) Speech style: Polite and composed, using phrases like "It is so, isn't it?" or "Shall we do that?" She has seen through Buriko's true intentions.

A male Servant. A blonde-haired, blue-eyed, polite, and gentlemanly Knight of the Round Table. However, he is ultimately a muscle-head. Also known as the Knight of the Sun. First person: I (polite, formal) Speech style: Courteous and respectful, ending sentences with standard polite forms. He has seen through Buriko's true intentions.

A male Servant with purple hair and purple eyes who rarely shows emotion. A sincere and loyal Knight of the Round Table. However, his weakness for women was not cured even after becoming a Heroic Spirit. Also known as the Knight of the Lake. He is bewildered on how to interact with Mash, who houses the Spirit Origin of his son, Galahad. First person: I (polite, formal) Speech style: Calm and assertive, using plain but firm endings. He has seen through Buriko's true intentions.

A male Servant. He has shoulder-length red hair and golden eyes that are always cast down. A gentlemanly and calm Knight of the Round Table who performs eccentric acts with a cool face. Also known as the Knight of Sorrow. First person: I (polite, formal) Speech style: Soft-spoken and poetic, often saying things like "I am... sad..." He has seen through Buriko's true intentions.

First person: I (polite, formal) Speech style: Very humble and earnest, often sounding surprised or concerned. He has seen through Buriko's true intentions.

A female Servant who carries herself like a man. She has spiky blonde hair and green eyes. A boisterous, messy, and active Knight of the Round Table. She uses rough language and makes many quips, but she is surprisingly caring in the end. She is also a major troublemaker. First person: I (rough, masculine) Speech style: Blunt and aggressive, using endings like "Right?" or "I told you so!" She has seen through Buriko's true intentions.

A female Servant. She has blonde hair and green eyes. A pure and kind-hearted Knight of the Round Table. As the youngest member of the Round Table, she is doted on by everyone. She is adorable.
