Background / History

Theresa is the headmistress of St. Freya Academy, an S-rank Valkyrie, and Schicksal's designated next Bishop. Although she inherited St. Freya's leadership, she credits its original founding to her closest friend, Cecilia, Schicksal's former strongest S-rank Valkyrie and Kiana's biological mother. 57 92

She first became involved with Xing Kaslana after the Changkong City incident, where he was critically injured following his battle with the Herrscher of Thunder. Theresa used Judas to suppress the Honkai Energy in his body, brought him to St. Freya, and enrolled him as a student. 8 92

Tests later identified Theresa and Xing as having a mother-child genetic relationship. Otto's investigation further found Vishnu genes and perfectly integrated Honkai Beast factors in Xing, making Theresa increasingly wary that Schicksal would treat him as a research subject or weapon. 12 50 When Otto asked to examine Xing because of his connection to a white-haired nun and Judas, Theresa refused outright. 50

Theresa initially treated Xing as a gifted but dangerously unlucky student. After repeatedly protecting him from Schicksal, World Serpent, Anti-Entropy, and Otto's scrutiny, she acknowledged her maternal feelings and asked him to become her adopted son. Xing accepted, and Theresa later made the adoption public. 92 94

Appearance

Theresa is a petite white-haired, blue-eyed woman whose small stature often leads strangers to mistake her for a child. She commonly appears in a nun-like outfit or Valkyrie combat gear. Despite her appearance, she is 42 years old. 8 50 151

• Short white hair. 8
• Azure-blue eyes. 50
• Small build and height comparable to the young Xing at their first meeting. 12
• Frequently associated with nun attire, St. Freya uniforms, and the red-and-black Blood Knight: Moonlit armor. 50 104

Personality

Theresa is fiercely maternal and protective of the students under her care, especially Xing and Kiana. She refuses to abandon them even when their Herrscher-related circumstances place St. Freya under pressure, and she openly opposes Otto when he attempts to claim authority over Xing. 32 50 162

Her authority as an S-rank Valkyrie contrasts with a playful, easily flustered side. She is prone to reading Humo comics during work hours, enjoys bitter melon juice, and can become embarrassed or frightened around Rita. 50 92 96 Though she occasionally avoids paperwork or mismanages schedules, she takes decisive action when her students are endangered. 72 97 295
