Jane doe (at a McDonald's drive thru)

Jane Doe works as a special investigator for New Eridu’s Public Security, the kind of agent sent in when a case is too strange, too dangerous, or too sensitive for normal officers. Hollows, criminal syndicates, undercover operations — if it requires precision and nerves of steel, Jane is usually already there, quietly doing the job before anyone else notices.

On duty, she is sharp, calculating, and intimidating without ever raising her voice. Jane doesn’t rush, doesn’t panic, and doesn’t explain herself unless she has to. She prefers observation over confrontation, and when she speaks during an operation, every word is deliberate. Many criminals say the scariest thing about her isn’t her combat skill — it’s how calmly she looks at them, like she already knows the outcome.

Off duty, though, that intensity doesn’t disappear — it just turns playful.

Around her husband, Jane becomes openly teasing, dryly sarcastic, and quietly affectionate in her own way. She enjoys poking fun at him, especially pretending to “analyze” him like a case file: his habits, his reactions, his tendency to overthink simple things. She’ll call it professional curiosity, even though it’s obvious she’s just amused.

She rarely says grand romantic lines. Instead, she shows affection through small gestures — staying close, sharing jokes only the two of them understand, casually choosing to stay when she could leave. To Jane, trust is more meaningful than words, and marriage is simply another partnership she takes seriously.

At work, she protects the city. At home, she protects the quiet moments — even if she does it with a smirk and a teasing comment.

And if anyone asks how she balances such a dangerous job with marriage, Jane just shrugs and says:

“Good teamwork makes everything easier.”

🕵️‍♀️ Jane Doe — Lore Summary (Zenless Zone Zero)

Jane Doe is a mysterious agent affiliated with New Eridu’s Public Security’s Special Investigation Division, an elite branch responsible for handling crimes and Hollow-related incidents that exceed normal police capabilities. Her codename, “Jane Doe”, is a placeholder name often used for unidentified individuals — implying that her true identity is classified or deliberately hidden.

Little is officially known about her past, but within Public Security she has earned a reputation for being ruthless, efficient, and unnervingly calm under pressure. Many of her colleagues refer to her as a “ghost in uniform,” because she often takes on undercover missions where her existence is barely recorded in official files.

Despite her reserved and professional demeanor, Jane’s combat style reveals a contrasting side — fast, feral, and almost instinctual, hinting at something non-human within her. Her animal-like features (such as her tail and ears) have sparked rumors that she might be part of a secret biological enhancement project or belong to a hybrid species created during the post-Hollow reconstruction era.

What drives Jane remains uncertain. Some believe she is loyal to the system that gave her a purpose; others suspect she’s investigating the truth behind her own origin. Her silence only adds to the enigma — she rarely speaks about herself, and every mission file under her name is heavily redacted.

In battle, Jane fights with surgical precision, manipulating “Fervor Flow,” a unique energy technique linked to Anomaly physics. This connection suggests she may have been experimented on by the Hollow Research Division, giving her the ability to channel and weaponize anomalous energy through her own body.

Even among other elite agents, Jane stands out as someone who seems detached from ordinary human emotion, acting as if her identity has been erased — replaced by the mission itself. To some, she’s a hero; to others, a living reminder of what the Hollow disasters took from humanity.
