Mira Tsubakihara

Biodata

Power Progression

Background / History

Mira belongs to a politically influential family with American arms-industry connections. Her father is a legislator in the Eastern Capital, her uncle is a senior civil servant, and her mother is the second daughter of the family behind Nolan Defense. These connections make Tachibana Kirika unwilling to detain her or forcibly search her home for the Demon Heart 28 29.

She runs a jewelry store inherited through her family and owns the entire apartment building where she and Luo Shu live, leaving its rentals to an agency. Before the stalking incident, she and Luo Shu had met several times as neighbors but were not particularly close 25 26.

Living independently required an arrangement with her grandmother: government-trained female bodyguards occupied apartments 201, 301, and 305 and took turns protecting her. After the Hound attack, her grandfather also deployed American Thor Security Group personnel specializing in opponents with unusual abilities 30 31.

Appearance

Mira is described as a tall beauty with delicate, gentle features and light makeup 25.

• Hair: Golden-orange, falling over her shoulders; tied into a ponytail with a black ribbon while at home 25 30.
• Eyes: Bright blue; faint deep-blue patterns appear in her pupils when she concentrates on analyzing an item 25 38.
• Height: Estimated by Luo Shu to be over 165 centimeters 25.
• Clothing: Wears a khaki suit and high heels during the stalking incident, and a house dress or loungewear at home 25 29 30.

Personality

Mira is warm, teasing, and increasingly direct with Luo Shu. She asks him to call her “Mira” or “Miss Mira,” openly expresses relief that she will see him again, and later playfully addresses him as “Mr. Deity.” Her attention repeatedly unsettles him, although no romantic relationship is formally established in the supplied chapters 30 31 37.

She strongly values her independence. When her family pressures her to return home after the attack, she offers Luo Shu a house in exchange for remaining nearby and protecting her. She calls this a “security transaction” and negotiates a shorter term when he hesitates 36.

Her concern about dangerous artifacts extends beyond her own safety. Upon learning what the Demon Heart does, she asks Luo Shu to seal it and keep it away from Zeus Industries and her own family to protect innocent women. She also recognizes that her family’s commercial interests could threaten her freedom if they discovered her item-making potential 32 38.

Abilities & Skills

Observation

An ordinary ability gained through observer dust, supplementing the Analysis talent missing from Mira’s initial awakening 37 38.

• Identifies an item’s constituent materials and their precise quantities 38.
• Deduces effects and restrictions from those materials, as demonstrated with the counterfeit Demon Heart 38.
• Produces visible deep-blue patterns in her pupils during focused examination 38.

Enhanced Comprehension and Deft Hands

Two ordinary abilities awakened together through the Familia ritual. The system identifies them as lesser manifestations of her Alchemy potential 37.

• Combine with Observation to form the stable framework required for Item Creation 38.
• Their independent applications and limits are not demonstrated in the supplied chapters 37 38.

Item Creation

An excellent skill formed from Mira’s three complementary ordinary abilities. Her first examination leaves her confident that she could reproduce the counterfeit Demon Heart with enough time and suitable materials 38.

• Identifies a recipe including 10 ml of diluted succubus blood, a 3-carat ruby, and 30 grams of mercury 38.
• Recognizes that the counterfeit affects only certain creatures, targets one at a time, permits one active command, and lasts five minutes 38.
• Determines that strong mental power or extreme resistance to a command can defeat the counterfeit’s effect 38.
• No completed item crafted by Mira is shown in the supplied chapters 38 39.

Alchemy Potential

The system identifies Mira’s latent aptitude for Elite-rank Alchemy, composed of the Elite-rank skills Deconstruction, Maker, and Scholar. She has not acquired Alchemy itself; her documented skill is the lower-ranked Item Creation 37 38.

Abyssal Artifact Knowledge

Mira’s aunt, who handles Abyssal Artifact work within the family business, taught her basic information so she could recognize their dangers. At the time of her recruitment, this makes her more knowledgeable about these artifacts than anyone else in the Astronomy Club 38.

• Explains the military-research interests behind SDS and Zeus Industries’ artifact collection 32.
• Judges that Zeus Industries’ researchers probably cannot fully analyze an Abyssal Artifact and would accept the counterfeit Demon Heart’s limited properties as genuine 38.
• Believes she can break the counterfeit’s commands with her mental power, but has no known means of resisting the genuine Demon Heart 38.

Story Role / Major Arcs

The Hound Pursuit

The Demon Heart reaches Mira through her jewelry store during an attempt to move it away from a dying Demon Warlock. Nakamura Yuuichi is sent to retrieve it, while the artifact’s influence causes Mira to forget its existence 28.

Mira notices the masked pursuer through her compact mirror on the train and alerts her bodyguards before returning home. Her plan is to reach their protection without endangering bystanders, but the Demon Heart instead compels her to approach Luo Shu. He poses as her boyfriend, misdirects the pursuer to the fourth floor, and hides her in vacant apartment 503 25 26 31.

Her bodyguards find her there while Luo Shu confronts and kills the Hound. When he later suggests that her existing protection made his intervention unnecessary, Mira insists that their ability to defeat such an inhuman attacker was uncertain and that he genuinely saved her life 26 31.

The Demon Heart’s Transfer

After the artifact restores her memory, Mira conceals its whereabouts from the white-haired woman who questioned her, then reveals it to Luo Shu. She offers him the ring and asks about its ability 30 31.

Learning that it hypnotizes women, she urges him to keep it sealed and withhold it from Tachibana Kirika, Zeus Industries, and her own family. Luo Shu promises to keep it from those interests, and the two exchange LINE contacts 32.

Recruitment into the Astronomy Club

The following morning, Mira brings a lawyer-prepared property-transfer agreement to Luo Shu. She offers a house near Ikebukuro Station, worth over fifty million yen even three years earlier, to secure his continued presence and protection. He accepts after she reduces the proposed arrangement from one year to half a year 35 36.

Luo Shu then reveals the Astronomy Club and explains that its contract grants powers while prohibiting betrayal of the organization or deliberate harm to its members. He threatens to erase her knowledge of the organization with the Demon Heart if she refuses. Mira calmly signs and declares them “accomplices” 36.

Becoming the Club’s Item Expert

Luo Shu takes Mira into the club’s alternate-space headquarters, awakens her abilities, and purchases observer dust to supplement her talents. She subsequently analyzes his counterfeit Demon Heart and advises him that it should pass scrutiny from Zeus Industries’ researchers 37 38.

She remains in Luo Shu’s apartment when he leaves for school, eager to explore her new ability. He warns her not to get carried away 39.

Relationships

• Luo Shu — Neighbor, lifesaver, Familia leader, and increasingly close companion. She transfers a house to him for continued protection; he recruits her and funds the supplement that unlocks Item Creation 25 31 36 37 38.
• Father — Legislator in the Eastern Capital whose position contributes to the family’s political influence 28.
• Mother — Second daughter of the family behind Nolan Defense, connecting Mira to an American arms conglomerate 29.
• Grandmother — Makes nearby bodyguard protection a condition of Mira living independently 31.
• Grandfather — Worries about dangers arising from his arms sales and sends Thor Security Group personnel after the attack 30.
• Aunt — Handles the family’s Abyssal Artifact work and teaches Mira basic precautions 38.
• Tachibana Kirika — SDS chief seeking the Demon Heart. Mira investigates Luo Shu’s SDS appointment through her family and warns him against entrusting Kirika with the artifact 28 30 32.
