Background

Theresa first knows Xu Qi as his online friend, using the name of Z Alahato’s protagonist as her account ID. Xu Qi initially assumes that she is a blue-haired boy; she conceals her gender until their conversation shortly before their in-person meeting. 40 53 54

She meets Xu Qi at the hospital after he helps rescue her friend, Su Muqin. Although they recognize one another immediately through their online mannerisms, they initially feel like “the most familiar stranger” to each other. 57 58

Theresa is emotionally invested in Su Muqin’s recovery and becomes determined to uncover why she attempted suicide. She cautiously accepts Xu Qi’s help in examining Muqin’s phone data, prioritizing his safety even while pursuing the evidence. 59 71

Her background remains largely hidden until much later. Theresa is revealed as the 439th-generation member of the Apocalypse family and Otto Apocalypse’s granddaughter. Mobius subsequently identifies her as a survivor of cloning experiments associated with Otto and Anti-Entropy, which causes Theresa to break down when confronted with the implications of her past. 823 824

Appearance

Theresa initially has white hair, azure eyes, and a notably petite build; she is stated to be 1.45 meters tall. Her childlike appearance contrasts with her status as an adult special-police officer. 58 739

• Often dresses in cute, Gothic-inspired or blue-and-white outfits. 128 739
• Wears white stockings, which become a recurring point of teasing between her and Xu Qi. 741
• Has sharp upper canine teeth after her transformation and develops a craving for Xu Qi’s blood. 857 858
• Following her second awakening, her hair grows nearly to the ground, her eyes gain a crimson hue, and her physique becomes tall and mature while retaining her baby-faced features. 853 856

Personality

Theresa is proud, stubborn, and frequently tsundere toward Xu Qi. She responds to affection with denials, scolding, or mock hostility, but becomes visibly flustered when her feelings are exposed. 61 104 128

Despite her bravado, she suffers from social anxiety around unfamiliar people and envies the warmth of Xu Qi’s household. Her friendship with Griseo and acceptance by the Golden Courtyard gradually give her a stronger sense of belonging. 60 61

She is compassionate and deeply rejects Qin Fusu’s belief that certain lives are worth more than others. Su Muqin’s death hardens her resolve, but her motivation remains justice for the victims rather than simple vengeance. 88 93 94

Theresa is also an enthusiastic Alahato fan, particularly interested in robots, celestial bodies, aliens, and science-fiction stories. 430 667 746
