Lacerta

Biodata

History

Departure from the New Federation

Lacerta is the child of a high-ranking New Federation official. Despite her family background, awakening Resonance Power forced her to leave the New Federation and seek opportunities elsewhere 38. She later became Stardust Academy’s principal while also teaching its preparatory students 5.

Lu Guan’s Enrollment

While collecting incoming students, Lacerta intercepted Lu Guan’s accidentally unleashed Great Spiraling Ring of Yu to protect the welcoming party. She lost consciousness and was hospitalized; afterward, she explained that she had overexerted her Resonance Ability rather than suffered a serious injury 4 5.

Huanglong’s advance reports had led her to expect a problem student, but Lu Guan’s sincere admission of fault changed her opinion. Instead of imposing a harsh punishment, she appointed him her temporary teaching assistant, requiring him to learn the course material, explain it when necessary, and help organize study activities 5.

Recognizing that she lacked the expertise to solve his uncontrolled ability, Lacerta recruited Chisa to teach him. She subsequently raised his simulation access to Chisa’s level, observed his training, and stopped Hecate’s projection when he exhausted his Resonance Power 6 9 13 14.

Academy Dark Side Investigation

Lacerta investigated abnormal activity in the Academy Dark Side, a collective Sonoro formed from accumulated student emotions. She detected a foreign frequency that could neither be located nor analyzed and connected it with worsening student mental health. Although she informed Lu Guan, she insisted that the adults would handle the danger and restricted his access to the simulation grounds 16 17.

Together with Lu Hes, she found Lu Guan after his encounter with the Fractsidus president’s avatar. She explained that he would temporarily have to remain in Lahai-Roi under academy and Deep Space Union supervision for both monitoring and protection 19 20. Over the following two months, she used his information to mobilize Union forces against several Fractsidus spies, though the investigation did not establish that every infiltrator had been removed 22.

Defense of Dania

When the Deep Space Union reviewed Dania’s status as a Threnodian Resonator, Lacerta defended her right to remain a student: Dania had violated neither school rules nor regional law. Lacerta opposed every committee proposal except Huanglong’s and maintained that her student would not deliberately harm the academy or Union 37 48.

As negotiations deteriorated, she gave Lu Guan Aalto’s contact information to secure Black Shores support. She also deliberately let students learn what the committee was considering, helping opposition to its plans gain momentum 46 49.

Lacerta accompanied Dania into the hearing and presented evidence supporting her continued enrollment. When committee members instead advocated imprisonment or laboratory confinement, Lu Guan intervened violently. Lacerta initially tried to restrain him, but ultimately refused to let her student bear the consequences alone 53 54 55.

Using Disordered Memories, she killed committee members with ulterior motives concerning Dania. Her mother and Huanglong’s representative remained unharmed. Lacerta defended her actions as part of her responsibility to educate, guide, and protect students, openly rejecting the committee’s authority to disregard evidence for its own interests 55.

After the Committee Purge

At the delayed opening ceremony, Lacerta publicly attributed the committee deaths to a Fractsidus attack and praised Dania for stopping Scar. When Lu Guan’s alterations made her prepared speech unusable, she discarded it and improvised a statement reaffirming Stardust Academy’s ideals 59.

She approved of Dania’s future with the Black Shores and helped coordinate the academy’s new research priorities, including Mornye’s investigation of Desolation and prospective Black Shores assistance 59. She later vouched for Lu Guan during Lu Yi’s inspection and approved his departure for Jinzhou, assuring him that both the academy and Union would support him if needed 62 76.

Personality

Lacerta places her duties as a teacher above institutional convenience. She responds to honest mistakes with guidance rather than condemnation, worries about the psychological burden of uncontrolled abilities, and treats protecting students as part of education. Her defense of Dania eventually takes her from formal advocacy to personally killing committee members rather than leaving Lu Guan solely responsible 5 48 55.

She also has a playful, easily exasperated side. Lu Guan’s theatrical combat lines and pranks repeatedly strain her composure, while his romantic success makes her self-conscious about never having had a relationship. She participates in mischief herself, accepting experimental candy specifically because she wants to see Chisa’s reaction 13 14 23 59 60. Despite teasing Lu Guan about Dania and Sigelika, her central concern is that he treat both girls well 73.

Abilities & Skills

Memory Palace

Lacerta’s Resonance Ability creates an internal memory palace 23.

• Stores remembered material, including adult films she privately recalls when recognizing the nature of Lu Guan and Dania’s interrupted conversation 23.
• The provided account does not establish the palace’s capacity or whether it can be accessed by others.

Disordered Memories

Lacerta invokes “Disordered memories… Take shape!” during the committee purge, using her ability lethally against multiple members 55.

• Kills the targeted committee members within approximately three minutes 55.
• The precise forms manifested and the ability’s wider combat limitations are not described.

Protective Use of Resonance

Lacerta uses her Resonance Ability while taking the force of Lu Guan’s accidental explosion to protect others 5.

• The exertion leaves her unconscious and requiring infirmary treatment 5.
• She attributes her condition to overusing her ability, not a severe injury 5.

Frequency Detection and Sonoro Knowledge

Lacerta recognizes a frequency within the Academy Dark Side that does not belong to the academy 16.

Relationships

• Lu Guan — Student and temporary teaching assistant. Their relationship develops from an alarming first meeting into mutual trust, frequent teasing, and Lacerta’s willingness to share responsibility for his actions 5 55 59.
• Dania — Student whom Lacerta defends against confinement and experimentation. She personally reassures Dania before the hearing and later supports her prospects with the Black Shores 48 53 59.
• Kaiermei'er — Biological mother and permanent secretary-general of the Deep Space Union’s board of directors. Their disagreement over the committee purge exposes the conflict between Lacerta’s teaching principles and her mother’s institutional concerns 54 55.
• Chisa — Teaching colleague recruited to help Lu Guan control his ability. They observe his training together, discuss threats to the academy, and become occasional targets of one another’s teasing 9 13 23 49 60.
• Lu Hes — Academy doctor and investigative partner. He accompanies her into the Academy Dark Side and supplies the experimental candy she intends to give Chisa 19 20 60.

• Aalto — Black Shores representative whose assistance Lacerta seeks to strengthen Dania’s defense before the committee 46 49 52.

Walkthrough System Role

Lacerta is one of Lu Guan’s romanceable characters, but the documented affection milestones do not establish a romantic relationship between them 6 14 24.
