OVA
Description
Jo is the central protagonist of Burst Angel: Infinity, an original video animation that expands upon the main storyline. She is a young woman whose most distinguishing physical features are her silver-gray hair and piercing red eyes, a combination that, along with her combat prowess, contributes to her fearsome reputation. Her typical attire is practical and no-nonsense, and she is almost always seen armed with a pair of large-caliber Desert Eagle pistols. Across her left shoulder and arm is a unique, wing-shaped tattoo or mark that begins to glow when she taps into her full potential, an outward sign of her extraordinary and unnatural abilities.

Jo's personality is defined by a stark contrast between her cold, taciturn demeanor in daily life and the fierce, unrestrained intensity she displays in battle. She rarely smiles or shows overt emotion, preferring a deadpan and direct manner of speaking, and she has little interest in social graces or mundane concerns like money. Her solitary and brusque nature leads her to keep most people at a distance. When not on a mission, she finds entertainment in watching horror and gore-related movies, a pastime that aligns with her otherwise grim and serious disposition. However, combat brings out a different side of her; it is the one activity where she genuinely seems to come alive, finding pleasure and a sense of purpose in the thrill of the fight.

Her primary motivation stems from a deep, unwavering loyalty to her partner, Meg. Jo explicitly states that Meg is the one she fights for, and this relationship is the emotional core of her character. This protective instinct overrides almost everything else, and any threat to Meg is met with immediate and lethal force. While Jo is a formidable fighter, she does not fight for grand ideals or monetary gain; her world largely revolves around ensuring Meg's safety and carrying out the jobs assigned to them. In the Burst Angel: Infinity OVA, which is set during their time in New York City before joining the larger group, this dynamic is on full display as Jo and Meg return to visit an orphan friend of Meg's, only to become entangled in a violent situation that requires Jo's skills.

Jo's role in the story is that of the primary enforcer and combat specialist. She is the "muscle" of her small group, possessing the superhuman abilities necessary to take on overwhelming odds, including piloting a large mecha named Django for high-stakes missions. Her reputation precedes her, with enemies and allies alike referring to her by fearsome nicknames such as the Angel of Death or the Hell Angel, a testament to her lethal efficiency and the high body count she leaves in her wake.

The most significant relationship in Jo's life is with Meg, who serves as her emotional anchor. Their bond was forged in the past when Meg, an orphan, took care of Jo, and this debt of gratitude and affection has transformed into an absolute, all-consuming devotion. The series heavily implies that Jo's feelings for Meg are romantic, and this connection is the primary lens through which her character is explored. While she works alongside Sei and Amy, her interactions with them lack the same depth and personal investment that she has with Meg.

The mystery of Jo's background is a critical element of her development. She has no memory of her past, not knowing who she is or where she came from. The truth, which she eventually rediscovers, is that she is not fully human; she is an artificial being, a genetically engineered weapon created in a secret laboratory as a "Genocide Angel" designed for warfare. This revelation forces her to confront her own nature as a killing machine. When her friends are taken hostage, she even surrenders to be reprogrammed to ensure their safety. Her arc culminates in a choice to defy her origins, turning her destructive purpose against the organization, RAPT, that created her. In a final act of protection, she knocks Meg unconscious and leaves her behind to face this final mission alone, demonstrating that her love for Meg has ultimately given her a humanity that transcends her artificial creation.

In terms of abilities, Jo possesses superhuman reflexes, endurance, and combat instincts. Wrist-mounted devices on her arms enhance her already incredible gunfighting skills, allowing her to draw and shoot with preternatural speed and pinpoint accuracy. She is a master of gun-kata, often engaging multiple opponents in close quarters while dual-wielding her signature pistols. When her wing-shaped tattoo activates, her power increases exponentially, pushing her abilities far beyond normal human limits. In addition to her personal fighting skills, she is also the primary pilot of a large, white cybot or mecha named Django, which she uses for larger-scale operations and to provide heavy support for her friends.
