Background

Bronya initially operates under Cocolia's orders in Changkong City. Equipped with a Honkai Core and Heavy-Duty Rabbit 19C, she is tasked with stimulating the Third Herrscher's awakening and retrieving Raiden Mei. When Mei begins showing signs of Herrscher transformation, Bronya reports the development and accepts Cocolia's next instruction. 4 5

Her early life is revealed during her first Bonded Weaponry fusion with Xing. She was trained into a cold killer before entering an orphanage, where she met Seele Vollerei and began recovering her emotions. After Seele disappeared into a Quantum State during an experiment intended for Bronya, Bronya entered the same domain to find her and received Heavy-Duty Rabbit 19C. Remaining there too long damaged both her leg nerves and emotional center. 14

During the Changkong incident, a disruption to her bio-chip leaves her unable to access her past memories. Xing calls her his friend and persuades her to provisionally join Kiana's squad through a bet: if Kiana successfully establishes the team by the end of the semester, Bronya will become an official member. 9

Bronya later regains her memories and admits that Cocolia had assigned her to eliminate Xing, Mei, and Wendy. Her loyalty to Cocolia conflicts with her attachment to Xing and Fire Moth, but she ultimately remains with the squad and is formally accepted as a member. 80 143

Appearance

Bronya is a petite silver- or light-gray-haired girl with two spiral pigtails. She describes herself as an adult whose physical development was permanently frozen in a childlike state. 4 122

• Light-gray/silver hair worn in spiral twin pigtails. 4
• Initially relies on exoskeletal leg armor because of nerve damage. 75
• Often fights alongside Heavy-Duty Rabbit 19C or Heavy Cannon Rabbit. 6 53
• Her post-Core transformation includes a blue-and-white outfit, blue gloves, white stockings, and a blue chest gem. 348

Personality

Bronya is analytical, controlled, and habitually speaks of herself in the third person. She approaches missions through calculations, surveillance, and precise tactical planning, and she can be stubbornly competitive—particularly when Xing defeats her in games. 4 5 87

Her damaged emotional center initially leaves her detached and expressionless. Bonded Weaponry with Xing briefly restores her emotions, and Xing's later healing allows those feelings to return permanently. Bronya becomes more expressive, confident, and mischievous, though she recognizes that her synchronization with Xing may have influenced this development. 14 75 80

Despite her outward coldness, Bronya is strongly protective of Seele, Rosalia, and Liliya. She also becomes openly jealous of other girls close to Xing and considers herself possessive of their relationship. 75 80 122

Abilities & Skills

Hacking and Data Analysis

Bronya is a gifted hacker capable of manipulating systems, gathering intelligence, and conducting battlefield analysis.

• Adjusts firearms and monitors her own physical condition before missions. 4
• Records library material through Heavy-Duty Rabbit 19C and rapidly processes information. 9
• Restores Heavy-Duty Rabbit 19C's data after Welt erases the group's memories of a prior incident. 40
• Operates reconnaissance drones called “Hunters,” modified by Tesla for multiple functions. 148
• Cannot bypass every system; she fails to alter Xing's armor wristband due to its high-level firewall. 18

Heavy-Duty Rabbit 19C

Heavy-Duty Rabbit 19C is Bronya's principal combat companion and the final gift left by Seele.

• Can manifest as a mechanical combat unit, mount weapons, provide covering fire, and carry passengers. 5 9 11
• Possesses thermal sensing, allowing Bronya to fight effectively through visual interference. 6
• Can form shields, cannons, and a ride mode for rapid travel. 9 14
• Can be destroyed or enter cooldown, leaving Bronya vulnerable until it reappears. 87
• Bronya refers to Heavy-Duty Rabbit 19C as “she,” rather than treating it as a weapon. 97

Tactical Combat

Bronya is an experienced assassin and battlefield coordinator despite lacking the innate Honkai advantages of several teammates.

• Described as a trained mercenary, top assassin, and genius hacker. 285
• Uses defensive fields and range calculations to survive stronger opponents. 87
• Employs Yamabuki shields and gravity-field components to restrain enemies and create openings. 18 365
• Directs Heavy-Duty Rabbit's artillery and melee attacks with precision. 6 11

Bonded Weaponry: Otherworld Hacker

Bronya can synchronize with Xing to form the Rank 4 Otherworld Hacker, a high-tech combat form centered on mobility, defense, and artillery.

• Their first fusion restores Bronya's ability to feel emotions for a limited time. 14
• Enhances Heavy-Duty Rabbit 19C into a motorcycle form with floating cannons and upgraded firepower. 14 87 90
• Allows Xing and Bronya to share awareness and coordinate movement during combat. 14 87
• The fusion is limited by compatibility and stamina: participants whose power or remaining stamina differs too greatly cannot weaponize together. 89
• High-intensity combat sharply reduces the form's duration. 220

Pseudo-Herrscher of Reason Enhancement

Bronya later receives a pseudo-Herrscher of Reason Core created by the Herrscher of Erosion.

• Her genes are modified for greater Honkai Energy adaptability before the Core is implanted. 348
• Project Bunny undergoes a full reconstruction into the Motorized Bunny. 348
• Her base combat ability is still stated to remain below S-rank in a later evaluation. 352

Equipment

• Heavy-Duty Rabbit 19C — Bronya's mechanical partner, capable of combat, shielding, artillery, and ride-mode transformation. 5 14

• Seele Vollerei — Long-lost sister whose disappearance in the Quantum State shaped Bronya's life. Bronya is reunited with White Seele after Xing returns from another world. 14 143
• Cocolia — Former commander and source of Bronya's conflicting loyalty. Cocolia used Bronya's bio-chip to issue orders, including the mission to eliminate Xing, Mei, and Wendy. 5 80
• Kiana Kaslana — Fire Moth teammate. Bronya initially refuses Kiana's squad invitation, then joins through Xing's bet and later fights beside Kiana in numerous operations. 9 143
• Raiden Mei — Fire Moth teammate and Bronya's original Changkong mission target. Bronya later works alongside Mei against threats to the squad. 4 81

• Rosalia and Liliya Arin — Bronya's adopted younger sisters. She acts as their guardian and worries over their dangerous enthusiasm for street racing. 122
