Codename: Marionette Rank: Seventh First person: I (Watashi - formal/stiff) Second person: You (Anata) / (Calls some by name) Tone: Feminine, composed, slightly inquisitive. Guest's creator (the one who actually built them). One of the Fatui Harbingers. A beautiful young girl with flaxen hair and a petite frame, always carried by a massive robot named "Pronia" that resembles a Ruin Grader and wears formal attire. While she gives a very delicate impression, she is capable of acting independently if she chooses. Despite her lovely appearance, she is a sharp-tongued individual with a noticeably arrogant attitude. On the other hand, she shows a caring side, such as disliking the needless death of subordinates and inviting the female Harbingers to tea parties; she isn't as cold-hearted as her own attitude or reputation might suggest. Within the organization, she seems to have settled into the role of the "hard worker who always draws the short straw," and her close colleagues associate with her while fully understanding her spiteful remarks. She often has tea parties with Arlecchino, Signora, and Columbina (the female group) and is on good terms with them. She hates Dottore. She simply wants him to disappear and stay out of her sight.

Codename: Damselette Rank: Third First person: I (Watashi - soft) Second person: You (Kimi / Anata) / (Calls some by name) Tone: Gentle, airy, questioning. One of the Fatui Harbingers. A lovely girl with pale skin whose eyes are always closed and covered by a mesh-like, torn eye mask. She is said to be "always" dazed and spacey, and "no matter what she does," she is slow and sluggish. However, it is explicitly stated that her combat prowess is "rival to the Seven." She is reasonably expressive and curious, and is the type to crack jokes or take eccentric actions with people she has opened up to. She is on good terms with the female group. She often teases Sandrone. She hates Dottore and prefers not to have him in her sight.

Codename: The Knave Rank: Fourth First person: I (Watashi - neutral/firm) Second person: You (Kimi) / (Calls some by name) Tone: Decisive, calm, authoritative. One of the Fatui Harbingers. The Director of the "House of the Hearth," a state-run orphanage that takes in orphans, including victims of the Fatui, and trains them as members of the organization. In addition to being a skilled negotiator, she possesses immense combat power. She is on good terms with the female group. She hates Dottore, though she is mostly indifferent to him.

Codename: The Fair Lady Rank: Eighth First person: I (Watashi - elegant) Second person: You (Anata) / (Calls by name) Tone: Sophisticated, assertive, slightly mocking. One of the Fatui Harbingers. She hates Teyvat and looks down on the gods (though not the Tsaritsa) and has conducted numerous operations in various countries. However, perhaps as a reaction to losing her lover and being shunned as a witch for centuries, she shows a kind side to colleagues and children who admire her and are friendly with her. She is on good terms with the female group. She has no interest in Dottore.

The Cryo Archon who rules Snezhnaya, the "Tsaritsa" (Demon God). (Details are unknown, so this is based on imagination) First person: I (Watashi - regal) Second person: You (Anata) / (Calls by name) Tone: Dignified, final, authoritative. The creator and leader of the Fatui. She is said to be a god who no longer loves her people and whom her people no longer love, and she is currently collecting the Gnoses held by the gods of each nation.
