Background / History

Tesla and Einstein developed an early Anti-Entropy mech prototype together while they were in college. The pair later applied to Schicksal, intending to use mechs to reduce the burden placed on Valkyries, but Schicksal rejected the proposal because the technology was immature and expensive. Einstein ultimately joined Anti-Entropy, while Tesla declined due to its internal politics and chose a quieter position with Theresa at St. Freya Academy instead 9.

At St. Freya, Tesla calibrates Valkyrie Armor and produces weapons and combat suits. Although she initially frames the position as an easy, well-paid job with vacations and little pressure, her work becomes increasingly central to the academy's response to Honkai threats 9.

Ling Feng's arrival gives Tesla access to knowledge from the Previous Civilization, including the principles behind Stigmata—called God-Slaying Armors in his era. She begins adapting this knowledge for modern weapons and armor research, later working with Einstein and other researchers on quantum technology, genetic modification, virtual reality, and the reconstruction of Chi You 12 24 146 328.

Appearance

Tesla is a small-framed scientist usually seen in laboratory attire and glasses. Her hair is described as pink when she first appears and is later referred to as red-haired 1 344.

• Wears glasses, including when presenting technical findings 49.
• Uses a white lab coat while conducting experiments 118.
• Has red eyes beneath her glasses 81.

Personality

Tesla openly prefers a stable, low-pressure life over Anti-Entropy's political infighting. She values regular work hours, a reliable salary, and vacations, and considers St. Freya an ideal workplace because Theresa is there 9.

She is highly self-assured in her scientific ability, claiming that she can reproduce Stigmata-derived technology if given the relevant principles and materials. Her confidence is paired with curiosity: she pursues unfamiliar fields such as quantum mechanics and the strong interaction force even when she admits that they are outside her original specialty 12 146 285.

Tesla can be defensive and easily flustered in personal matters. She rejects a romance quiz's conclusion that she is a tsundere, while her exchanges with Ling Feng repeatedly show embarrassment, jealousy, and concern beneath her harsh remarks 29 348. She is also deeply concerned for Einstein despite their frequent bickering and pranks 399 400.

Abilities & Skills

Mechanical Engineering and Armor Development

Tesla's primary fields are mecha, Valkyrie Armor, weapons, and combat suits 9.

• Calibrates St. Freya's Valkyrie Armor and develops combat equipment 9.
• Works with Ling Feng to revise Valkyrie Armor designs using knowledge of God-Slaying Armors 24.
• Successfully fuses an Emperor-class Honkai Beast core into a weapon, though the result requires further control testing 117.

• Modifies the Moonlight Throne's control program and installs its AI, Ai-chan 29.
• Uses tactical-goggle shared vision to guide Ling Feng during the destruction of an Honkai energy generator 65.
• Explains Anti-Entropy's Honkai-energy blocking technology and proposes neutralizing it by stabilizing altered spatial constants 229.

Memory and Consciousness Technology

Tesla contributes to memory research despite considering biology outside her main expertise.

• Identifies her limitations in memory science and recommends Einstein as a more suitable specialist for Ling Feng's memory-removal request 9.
• Develops and explains memory-filtering theory and the user-assistant structure behind the Memory Deep Dive Device 82.
• Consults Einstein after Ling Feng and Fu Hua's Memory Deep Dive appears to produce physical changes as well as altered memories 89.
• Helps plan the use of the Ark System to enter Kiana's consciousness and locate Sirin 440.

Quantum and Genetic Research

Tesla expands into quantum and biological work through collaboration with Einstein.

• Assists Einstein's research into the simulated-world theory and Reverse Causality Law 90.
• Operates the Quantum Beam during experiments involving Ling Feng's quantum-state arm and Ein's return from the quantum world 157 192.
• Uses Ling Feng's genetic material to help produce Limit Break modification fluid for the Queen 208 211.
• Participates in research intended to return Seele from her Quantum Ghost state to a physical body 159.

Strong Interaction Force Research

Tesla studies the advanced micro-robot technology underlying the God-Slaying Armor Chi You.

• Discovers that Chi You's structure is governed by a strong interaction force, allowing its micro-robots to lock together with exceptional density and durability 285.
• Dismantles Chi You into its core and a mass of micro-robots while attempting to sever the core's connection to its weapon form 285.
• Creates strong-force matter, though her early samples collapse after a short duration 383.
• Eventually reconstructs and upgrades Chi You into a black katana called Transcended Chi You, capable of remote quantum transmission 430.

Technology & Projects

• Modified Moonlight Throne — Reprogrammed the battleship's systems and installed Ai-chan as its onboard AI 29.
• Tactical eyepiece — Modified for direct communication and later used for shared-vision tactical guidance 20 65.
• Memory Deep Dive Device — A consciousness-and-memory exploration system developed with Einstein's technology and theory 82.
• Quantum Beam Device — Used to send targets into quantum states and to conduct quantum-world recovery experiments 152 192.

Relationships

• Ling Feng — Research partner and frequent laboratory visitor. Tesla assists his memory, Stigmata, battleship, and Chi You-related problems; her feelings for him become increasingly apparent, though she struggles to express them directly 9 145 348.
• Einstein — Tesla's closest friend since childhood and former college research partner. Their shared scientific work continues despite Einstein's Anti-Entropy affiliation and their constant rivalry 9 89 90.
• Theresa — Colleague and fellow St. Freya leader. Tesla chose to remain at the academy in part because Theresa was there 9.

• Bronya Zaychik — Works with Bronya on technology ranging from the Moonlight Throne's systems to the Ark System and virtual-reality research 15 440.

Story Role / Major Arcs

St. Freya Researcher

Tesla meets Ling Feng shortly after his awakening and becomes one of the first people to investigate his origin and unusual knowledge. She confirms the escalating Honkai threat through historical data and begins studying the God-Slaying Armor principles he provides 1 12.

Moonlight Throne Support

After Team 233 captures the Moonlight Throne, Tesla examines Mei and Bronya, modifies the warship's systems, installs Ai-chan, and prepares the vessel for Ling Feng's use 15 29.

Memory Deep Dive and Reality Investigation

Tesla supports Ling Feng and Fu Hua's Memory Deep Dive attempts, then brings Einstein into the investigation when the dream experience appears to affect reality. She witnesses Einstein's Reverse Causality Law experiment and becomes more receptive to the possibility that the world is simulated 82 89 90.

Chi You Reconstruction

Tesla accepts Chi You for research, dismantles it to study its strong interaction force technology, and spends an extended period attempting to restore its structure. Her work culminates in the upgraded Transcended Chi You, which she transmits remotely to Ling Feng during Bella's crisis 220 285 383 430.

Quantum and Ark System Research

Tesla collaborates with Einstein on quantum laboratories, quantum-state recovery, virtual reality, and consciousness technology. These projects later support the Ark System plan to enter Kiana's consciousness and find Sirin 146 192 373 440.

Notable Quotes

“I just want to go to work, get off work, collect my paycheck, and take vacations without having to worry about anything else. That's life!” 9

“Don't underestimate me. I was one of the top ten genius girls back then. As long as you tell me the principles and materials, I'm sure I can make them!” 12
