Background / History

A deceased Honkai Impact 3rd fan awakens in a moonlit alley after transmigrating into the body of her favorite character, Moonlit Oath: Devotion to Love. Ai-chan informs her that returning home requires traveling through forty-nine worlds; she adopts the name Theresa while embracing “Miss Moonlit” as the identity most personal to her. 1 4 41

Initially disoriented by her female body and dangerous new world, she turns to the bounty system for survival, Crystals, and Valkyrie growth. Her first encounters establish the pattern that defines her early life: she mercilessly kills threats such as Lost Demons, Church pursuers, Fallen Angels, and corrupt Artifact Wielders, then converts their artifacts into resources or integrates the rarest ones herself. 3 5 6 21 22

Her rescue of Gasper and Valerie marks a major change in her priorities. Although she takes their Divine Artifacts, she gives them freedom, compensates them with Stigmata and weapons, and eventually makes Valerie her immortal blood Servant. 16 19 23

Appearance

Miss Moonlit is a tall, elegant young woman whose white hair, crimson eyes, fair complexion, and delicate fangs create an otherworldly vampire-like appearance. Her beauty is repeatedly noted by humans and supernatural beings alike, while her usual grace sharply contrasts with the brutality of her combat state. 7 10 11 36

• Long, bright white hair and blood-red eyes. 7
• Slender, refined fangs that look alluring rather than bestial. 4
• Standard attire includes a black long dress, gloves, boots, black stockings, and a lace collarbone chain. 7
• Her dress has a nearly ground-length hem decorated with black roses. 7
• Three blood-red Stigmata marks appear across her back while equipped with the Hana set. 8
• Also wears Kuoh Academy’s white-and-black sailor uniform with a red skirt. 41

Personality

Miss Moonlit is proud of her appearance and openly indulges her affection for the Moonlit Oath form she inhabits. She enjoys shopping, games, amusement parks, snow, plush toys, and dressing herself and her companions well; she reacts badly to being assigned melodramatic titles she never chose. 20 23 42

Her kindness is selective but genuine. She refuses to kill innocents merely for bounty rewards, saves victims of supernatural experiments, compensates people whose powers she takes, and repeatedly offers those under her protection freedom rather than forcing them to remain. 19 21 23 24

In battle, she is ruthless, thrill-seeking, and frighteningly direct. Her berserk state can overwhelm her emotions and leave her uneasy afterward, but she does not regret retaliating against those who threaten her or her companions. 5 6 15 27

She values voluntary loyalty over coercion whenever possible. Her Servants are treated as family, but she expects obedience and regards betrayal as incompatible with the life she shares with them. 32 54 66

Abilities & Skills

Moonlit Oath Physiology

Miss Moonlit has immense physical strength, exceptional speed, a low body temperature, fangs, and a natural affinity for bats. She is able to endure sunlight when necessary, though she dislikes it and struggles with daytime schedules. 6 7 12 41

• Transforms into a single bat or a swarm of bats for flight, escape, and infiltration. 6 8
• Commands bats and uses them as scouts or sensory extensions. 3 8 92
• Possesses no innate bloodlust despite her vampire-like form. 7
• Can use vampire hypnosis magic. 45
• Her raw strength is sufficient to lift a heavy tank. 12

Bloodstained Crimson Casket and Berserk Combat

Her signature weapon is the cross weapon Bloodstained Crimson Casket, which transforms into a pair of massive chainsaws. The weapon produces blood-red lightning and is her preferred answer to enemies too dangerous for ordinary Demon Swords. 5 8 15

• Uses high-speed dual-chainsaw attacks; during one castle battle, she swings at least forty times in a second. 15
• Her ultimate attack manifests a colossal red moon and channels “ten thousand years of longing” into a decisive killing strike. 15
• Enters a berserk state that dramatically raises her aggression, speed, and power. 15 31
• Berserk combat impairs her emotional control and can leave her remorseful after a massacre. 27
• The chainsaw can withstand and counter the Twilight Holy Spear. 90

Sephiroths Cup

After extracting the Sacred Gear Sephiroths Cup from Valerie, Miss Moonlit integrates it rather than recycling it. Its powers form the foundation of her survivability and her Servant network. 16 17

• Regenerates catastrophic injuries almost instantly, including a completely severed arm. 17
• Provides immense energy, life-based power, resurrection, and large-scale healing. 17
• Can heal vampires without harming them with holy power. 18
• Has developed Forbidden Hands concerning resurrection, healing, subverting life’s natural order, and creating forbidden life. 32 91
• Can restore a person so long as some trace of their existence remains, if developed far enough. 17

Evil Eye of World Stoppage

Miss Moonlit takes Gasper’s Evil Eye of World Stoppage after confirming that doing so will not prevent his future inheritance of Balor’s power. 18

• Stops time around targets, allowing her to interrupt attacks, capture opponents, or kill before they can react. 18 21 39
• Can freeze numerous enemies at once, including experimental subjects and magical beasts. 21
• Its duration decreases sharply against stronger opponents and is nearly ineffective against those much stronger than her. 21
• Can be countered by specialized disposable Artificial Artifacts. 39

Sword Creation

Miss Moonlit first uses Demon Sword Creation as a versatile transitional Divine Artifact, then develops it into a major part of her arsenal. 26 28

• Creates large numbers of Demon Swords with specialized elemental and anti-light properties. 26 29
• Her Forbidden Hand, Unlimited Lost Works, creates a vast bounded field filled with more than a thousand Demon Swords. 28
• Later develops and combines both Demon Sword Creation and Holy Sword Creation. 32 39
• Fuses the two artifacts with Infinite Power into True Holy Sword Creation. 96
• True Holy Sword Creation can create holy swords, demonic swords, divine swords, and even attempted God-Slaying weapons, subject to her ability to sustain them. 96

Dragon Emperor Powers

Miss Moonlit strips the Crimson Dragon Emperor’s Cage from Issei Hyoudou and becomes Vritra’s new host. She later acquires the White Dragon Emperor’s power from Vali, uniting both Heavenly Dragons under her control. 46 47 63 64

• Boost doubles her power every ten seconds, though repeated use places escalating strain on her body. 47
• Balance Breaker manifests crimson dragon armor and wings. 47 48
• Uses the dangerous Tyrant Dragon form in battle against Vali. 61
• White Dragon Emperor power halves an opponent’s strength and absorbs the lost power. 60 64
• Combines both powers into the Two Heavenly Dragons Armor, enabling rapid escalation against Demon King-class and stronger opponents. 64 90

Infinite Power

Through her alliance with Ophis, Miss Moonlit receives the power of the serpent and absorbs portions of the Infinite Dragon God’s blood. 52 53

• Permanently strengthens her body after she absorbs Ophis’s blood. 53 54
• Enhances Divine Artifacts beyond their normal limits. 54
• Allows Holy Sword Creation and Demon Sword Creation to begin fusing despite their opposing natures. 54
• Can be distributed to her Servants as a direct power boost. 70 85

Moonlit Servant System

By biting willing targets and sharing her bloodline, Miss Moonlit creates Servants bound to her life. The system is augmented by Sephiroths Cup and differs from conventional vampiric conversion. 12 23 58

• Servants are ageless and effectively immortal while Miss Moonlit lives. 12 17
• Servants do not fear sunlight or suffer bloodlust under her current Moonlit Oath form. 12
• Miss Moonlit can grant Stigmata, weapons, Sacred Gear projections, Infinite Power, and portions of her own strength. 58 66 70
• Growth in her Valkyrie rank strengthens her Servants, while their growth feeds power back to her. 64 84
• Her Servants’ lives remain tied to hers; if she dies, they die as well. 12 58

Learned Skills

Miss Moonlit uses system materials to develop abilities beyond combat. 22 45

• Mastered more than a dozen languages using skill materials. 22
