Background / History

Displacement from Mondstadt

Mona was studying the stars at her Mondstadt home when the sky shattered. A spatial current swept her and her astrological instruments into the Douluo Continent. She landed outside Suotuo City, lost her remaining Mora, and discovered that the unfamiliar world’s energy was suppressing her Hydro Vision 12.

Without usable currency or food, she established an astrology stall in the southern night market, charging ten Copper Soul Coins per reading. A rank-twenty-six Soul Grandmaster and two accomplices accused her of fraud, demanded a hundred Gold Soul Coins, and threatened to force her into an alley. Her attempt to defend herself with Hydro power failed under the world’s suppression 12.

Rescue and Vision Reforging

Chu Yuan broke the leader’s wrist, while Keqing incapacitated all three attackers. Mona recognized Keqing as the Yuheng of the Liyue Qixing and sensed that Chu Yuan’s presence stood above ordinary stars of fate. He helped her to the Golden Goblet Restaurant, where she ate and asked about his ability to calm her Vision 13.

At the Rose Hotel, Mona offered to divine Chu Yuan’s future as repayment. Instead of a Constellation, she saw a golden throne governing the stars of both Teyvat and Douluo. The resulting backlash shattered her brass astrolabe, and Chu Yuan protected her from its fragments 14.

Chu Yuan then reforged her Vision with the Crown of Heavenly Principles. The resonance between her Hydro origin, stellar fate, and his authority helped him reach level thirty-one and form his Third Divine Authority Soul Ring. The process also bound their fates together; afterward, Mona embraced and kissed him 15.

Zhu Zhuqing’s Rescue and Changed Fate

Using her strengthened divination, Mona located elemental relics and a threatened girl in Suotuo City. She guided the group to Zhu Zhuqing, identifying five hostile star tracks around her, including one belonging to an opponent above rank forty 16 18.

After Zhu Zhuqing’s rescue, Mona used a water mirror to reveal Dai Mubai carousing with courtesans. She also showed Zhu Zhuqing’s original fate: a life overshadowed by the White Tiger and constrained by an imperial marriage. This revelation helped Zhu Zhuqing reject the engagement and pledge herself to Chu Yuan 19.

Following Zhu Zhuqing’s transformation into the Divine Court’s first Night Scout, Mona confirmed that her Star of Destiny had become independent 20.

Auction and Shrek Academy Conflict

Mona accompanied Chu Yuan to the Rare Treasures Auction House, where she recognized ancient Mora containing concentrated Geo power and remarked on the purity of the Lumenspar Ore. The group acquired the relics despite Ning Rongrong’s competing bids 21 22.

During the subsequent confrontation with Shrek Academy, Mona mocked Flender’s recruitment attempt and warned Chu Yuan that Tang San relied on underhanded tactics. She also drew attention to the Great Soul Arena’s enormous audience when Tang San proposed a match 28 29.

Mona watched the wager match beside Chu Yuan rather than competing. After Keqing and Zhu Zhuqing defeated Shrek’s fighters, she accompanied him into the arena and later left with the group for the Seven Treasure Glazed Tile Sect residence 30 32 33.

Appearance

Mona has a delicate oval face, mint-green eyes, fair skin, and long dark purple-black hair worn in twin ponytails 12.

• Hat: A broad, pointed purple-and-black witch’s hat 12.
• Hair ornaments: Golden stars decorating the ends of her ponytails 12.
• Clothing: A fitted deep-purple and dark-blue astrologer’s bodysuit patterned with golden stars, accompanied by a cape 12 14.
• Stockings: Gradient-black, star-patterned pantyhose; torn during her arrival and later restored with starlight 12 16.
• Vision placement: Her Hydro Vision hangs at the small of her back 12.

Personality

Mona takes considerable pride in both her scholarship and Hydromancy. She objects to her work being dismissed as ordinary fortune-telling and insists that she does not deceive clients. Even while weakened by hunger, she tries to preserve the bearing of a distinguished astrologer 12.

She dislikes accepting favors without repayment. After Chu Yuan rescues and feeds her, she promises to repay him and offers a formal divination before he restores her Vision. Her intellectual curiosity also drives her to investigate his extraordinary fate despite her incomplete recovery 13 14.

Her scholarly confidence contrasts with her embarrassment over hunger, damaged clothing, and intimacy. After her Vision is reforged, she becomes openly attached to Chu Yuan, while remaining sharp-tongued toward people she considers arrogant or hostile, including Ning Rongrong, Flender, and Tang San 13 14 15 23 28 29.

Abilities & Skills

Hydromancy and Fate Reading

Mona reads fate through water, starlight, and astrological patterns. After her Vision is reforged, she can create star charts and water mirrors without a physical instrument 14 15 16 19.

• Remote observation: Follows the karmic connection associated with Zhu Zhuqing’s token to locate Dai Mubai and display his current activities 19.
• Fate interpretation: Explains how Zhu Zhuqing’s original star trajectory was subordinated to the White Tiger 19.
• Recognition of altered destiny: Detects Zhu Zhuqing’s newly independent Star of Destiny after her transformation 20.
• Limit: Cannot successfully divine Chu Yuan’s supreme fate. Contact with his authority causes destructive backlash and exhausts her Hydro reserves 14.

Stellar Reconnaissance

Her reforged Vision projects a floating azure star chart edged with golden Heavenly Principles patterns, reflecting energy flows across more than ten li 16.

• Locates three distinct Geo and Electro crystal reactions associated with fallen Teyvat minerals 16.
• Tracks threatened individuals and the hostile star trajectories surrounding them 16 18.
• Estimates an enemy’s approximate strength, identifying a pursuer above the fortieth-rank Soul Ancestor threshold 18.

Hydro Elemental Power

Mona channels Hydro through her Vision. Before its reforging, the Douluo Continent’s laws obstruct its use; afterward, her power exceeds its former Teyvat strength and is no longer suppressed by local Soul Power 12 15.

• Illusory Bubble: Attempts to use this technique to repel her attackers, but the attack fails before release because of elemental suppression 12.
• Starlight manifestation: Can directly summon starlight with a thought after reforging 15.
• Shared water-and-starlight movement: Chu Yuan’s newly acquired Stellar Fate Hydromancy: Illusory Bubble explicitly enables both him and Mona to transform into water and starlight and blink across vast distances 15.

Knowledge of Teyvat’s Laws and Relics

• Recognizes the Crown of Heavenly Principles as primordial authority above The Seven and the source of elemental power and stellar fate 14.
• Understands the principles behind Visions and the False Sky better than an ordinary Teyvat resident 14.
• Identifies ancient Mora containing concentrated Geo power and assesses the purity of Lumenspar’s elemental energy 21.

Equipment / Items

• Hydro Vision — Reforged by Chu Yuan; its blue crystal gains golden Heavenly Principles star patterns and immunity to Douluo Soul Power suppression 15.
• Brass astrolabe / divination basin — Used for water-based astrology; shatters when Mona attempts to read Chu Yuan’s fate 12 14.
• Astrological velvet cloth — A dark-blue, slightly worn cloth used to arrange her divination equipment. Mona angrily objects when a thug steps on it 12.
• Astrologer’s outfit and pointed hat — Her distinctive star-themed clothing survives her displacement, with its damaged stockings later repaired 12 16.

Relationships

• Chu Yuan — Rescuer, protector, and romantic partner. He restores and strengthens her Vision, binds their fates together, and receives her growing affection and personal care 13 15 21 30.
• Keqing — Fellow displaced Teyvat resident and companion. Keqing helps rescue Mona, reassures her about Vision reforging, and asks her to investigate Suotuo City’s elemental traces 13 14 16.
• Zhu Zhuqing — Companion whose rescue and rejection of her arranged destiny are aided by Mona’s tracking and Hydromancy 18 19 20.
• Ning Rongrong — Initially the target of Mona’s amusement during her treasure challenge; later joins the group and addresses her as “Sister Mona” 23 29.
• Tang San — An opponent Mona distrusts. She reacts coldly to his attempt to probe Chu Yuan and later warns about his tricks before the arena wager 17 29.
