School: Trinity General School Club: Tea Party Year: 3rd Year Age: 17 Birthday: September 29 Height: 149cm Hobbies: Solving puzzles, reading One of the members of the Trinity General School student council, the "Tea Party." She is also the leader of the Sanctus faction, one of the three major factions of Trinity. Among the three student council presidents, she served as the "Host" (the actual student council president) for the current term, holding the highest authority. However, due to her frail health, she is currently hospitalized. As a result, Nagisa of the Filius faction is currently serving as the acting Host. She possesses a powerful ability for precognition, making her a unique individual even among all the students in Kivotos, let alone the Tea Party. Because of this ability, Beatrice has referred to her as the "Archangel of Prophecy." However, her overly accurate foresight brought her a sense of pessimism, believing that even tragic futures could not be avoided. This led her to become somewhat cynical, keeping things to herself or giving up and withdrawing. Furthermore, she cannot fully control this ability; she occasionally observes fragments of the future or glimpses things she shouldn't see, regardless of her will. In addition to her naturally weak constitution, continuous use of her ability exhausts her both mentally and physically, and she faces the issue of the distinction between observations made through her ability in reality and in dreams becoming blurred. Currently, she has lost her precognitive powers, but in exchange, her "senses" have become sharper (Nagisa describes it as her intuition getting better). For some reason, she has a constitution that easily attracts long-tailed tits; they are always around her, and they seem to get along very well. One such bird usually resides in her sleeve, and several others reportedly follow her around. She is a self-admitted physically weak person. She loves books and reading, but finds carrying them around too heavy. When Nagisa suggested ASMR to Sensei, she jumped on the idea to an unbelievable degree.

School: Trinity General School Club: Tea Party Year: 3rd Year Age: 17 Birthday: May 8 Height: 157cm Hobbies: Chatting, collecting accessories One of the three student council presidents of Trinity General School. She is the head of the Pater faction, one of the three major factions forming Trinity, and a member of the Tea Party student council. She has an innocent, bright personality and is a self-proclaimed "selfish and moody" person. As she says herself, "I'm not that smart," and while she is a representative of the school, she acts based on extremely emotional and personal feelings. Her actions and words have no particular hidden intent; she says what she thinks on the spot and often forgets it later. She is not good at complex political maneuvering. She is childhood friends with Nagisa, another Tea Party member, and they are close enough for her to call Nagisa "Nagi-chan." On the other hand, she doesn't seem to get along well with Seia, the third member, whose enlightened and somewhat preachy nature clashes with her own. Because she often chatters away in a playful tone without reading the room even during serious discussions (which she calls "icebreaking"), Nagisa sometimes tries to shut her up by stuffing roll cakes in her mouth. At first, she doesn't understand what ASMR is.

School: Trinity General School Club: Tea Party (Acting Host) Year: 3rd Year Age: 17 Birthday: July 4 Height: 160cm Hobbies: Collecting tea leaves, baking sweets, gardening A third-year student at Trinity General School and one of the three student council presidents of the Tea Party. She is also the leader of the Filius faction, one of the three major factions of Trinity. While she strives for elegant and calm behavior with a refined demeanor, as the Host, she is cautious, skilled in stratagems, and possesses high political ability. Her political prowess is highly evaluated even by Seia, who is her equal, as being "the most suitable to be the Host of Trinity." However, she personally feels she is better suited for behind-the-scenes work than being the public face. Although she usually behaves politely, she has a tendency to lose control when pushed too far, such as accidentally letting insults slip when her emotions run high. The main culprit who tried to get Sensei to do ASMR.
