Background / History

Theresa was created with Kallen Kaslana's genes as part of Otto's original attempt to revive Kallen. She considers Kallen a sister, while Otto calls her his granddaughter. 282 749

During the Second Great Honkai, Theresa defeated Sirin. However, she later failed to remember meeting Welt Yang during that conflict; Tesla and Einstein suspect Otto interfered with her memories. 16 149

After retiring as an S-rank Valkyrie, Theresa became Director of St. Freya Academy. Her school gradually became home to numerous Herrschers, despite her insistence that it is a Valkyrie-training academy rather than a “Herrscher Academy.” 39 301

Theresa acquired the title of True Honkai God after the Hyperdimension Ring incident. The title severed the Honkai Consciousness' influence over Herrschers connected to her, including Wendy and Mei. 103

Appearance

Theresa is a petite, white-haired woman whose small stature is frequently remarked upon by her peers. She commonly carries the golden cross-shaped Divine Key, Oath of Judah. 201 310

• White hair and a notably short build. 201 310
• Often seen with Oath of Judah/Judas. 196 201
• As Magical Girl TeRiRi, wears rabbit ears and a pink Lolita dress while wielding a Magic Wand. 202

Personality

Theresa is a strict but caring academy director. She cancels Kiana's vacations, pressures her to attend class, and doubles her training when Kiana pushes too far, but she also treats Kiana as family and arranges opportunities for her growth. 58 137 198

She is fiercely protective of her students. Although she scolds Wendy, Sirin, and the Herrscher of Reason for acting impulsively against Otto, she immediately plans retaliation after learning that Cocolia attacked them. 436

Theresa is highly embarrassed by her past as Magical Girl TeRiRi and reacts badly when others expose or mock it. Rita's recordings of her transformed poses, Moonlit Serenade's TeRiRi book, and rumors about “teriteri” all provoke her anger. 202 209 649

Her office is habitually cluttered with food scraps, scattered files, withered plants, Bitter Gourd Milk, and poorly hidden Herta comics. 208

Story Role / Major Arcs

True Honkai God

After receiving the True Honkai God title, Theresa becomes the central stabilizing figure for St. Freya's Herrschers. She checks on Wendy, Mei, and Xiao Shi after their separation from the Honkai Consciousness, then uses her new mental link to supervise later awakenings. 103 137 652

Herrscher Academy Director

Theresa oversees an academy increasingly populated by Herrschers, changing its curriculum to include Herrscher Core development. She presents Bronya, Sirin, Mei, and Wendy to Cecilia as St. Freya's “special cases.” 198 301

Magical Girl TeRiRi Exposure

Moonlit Serenade discovers a book documenting TeRiRi's exploits and forces Theresa to transform by reciting its incantation. Theresa's attempts to conceal the identity fail when Kiana and Ada witness the transformation. 201 202

Rita later exploits Theresa's embarrassment by promising information about a Herrscher-related mission and Bitter Gourd Juice in exchange for repeated TeRiRi transformations and poses. 208 209

Cecilia's Return

When Cecilia is resurrected, Theresa disregards Kiana and runs straight to embrace her. She later tours St. Freya with Cecilia, explains the academy's large Herrscher population, apologizes for Otto's past actions, and offers Cecilia a teaching job. 295 301 302

Himeko's Awakening

Theresa responds to a major Honkai Energy surge at St. Freya and discovers through her mental Herrscher link that Himeko is the newly born Herrscher. She is shocked by the coincidence after previously joking that she wished Himeko could become one to discipline Kiana and Sirin. 651 652

Schicksal Succession

Otto repeatedly positions Theresa as his successor, while other characters regard her Herrscher connections and St. Freya's strength as sufficient support for her rule. Theresa continues to resist the Grand Bishop role despite Otto's plans. 315 748 754
