Rossi, full name Rossina Wulfperl Luppino, is one of the younger operators in Arknights: Endfield, and her exact age has been a recurring point of confusion for players. The game does not print a hard number on her profile, but in-game dialogue and lore narrow the window considerably.
What the game confirms about Rossi
Her character file lists a birthday of March 10 and identifies her as a Lupo of the Pack, younger sister of Wulfgard. She is a 6★ Physical Guard operator tied to Endfield Industries, obtained through Chartered Headhunting on the Scarlet Pearl-era banner cycle.
The dossier repeatedly frames her as a child. Her expertise entry for Situational Analysis explicitly calls out that "being able to sniff out a scam is a dangerous talent for a child," and the Pack's elders are described as wishing she could spend more time doing what she loves "at her age" rather than carrying leadership weight. The narrative treats her as young enough that her childhood itself is a plot point.
The 13-year-old floor
The cleanest age anchor comes from Rossi's own voice lines. At 100% trust, she confirms that the Pack's coming-of-age ceremony takes place when members turn 13, and she has passed it. A separate exchange between Baker and Wulfgard also places her above 13. That sets a hard lower bound.
Her combat history pushes the same direction without contradicting it. Her first battle happened at age 11, and she took her first mercenary contract at 13, which lines up with the Pack treating 13 as the threshold for taking on adult responsibilities within the clan.
The upper bound
Several story beats cap how old she can plausibly be. Wulfgard was already active as a mercenary when Rossi was an infant, and the main story sits 10 years after Endmin went into stasis. Her build, voice, and the fact that other clearly prepubescent children in her story quest describe themselves as "around her age" all point to mid-teens at the oldest.
Community consensus and third-party age trackers settle on 14 to 15 as the most supported range, with 13 to 16 as the outer bracket. The Endfield Hub also treats her as the youngest operator on the team in day-to-day dialogue.

Why players keep asking
Part of the confusion comes from a flashback in Wulfgard's quest that shows the two siblings sitting with Giovanni at what appears to be a similar apparent age, which clashes with the timeline where Wulfgard was already operating as a mercenary while Rossi was a baby. The simplest read is that the flashback's proportions are stylized rather than literal, and the written lore takes priority.
Her behavior around the Endministrator also gets misread. She grew up hearing stories about Endmin during the 10-year stasis gap, which produces fangirl-style reactions on their first in-person meeting rather than anything romantic. The Pack's partnership with Endfield Industries and her close relationship with Perlica explain how she recognizes Endmin almost immediately.
So while Gryphline has not printed a single canonical number, the combination of the coming-of-age voice line, Baker's dialogue, her combat timeline, and her dossier framing converges on the same answer: Rossi is a teenager in the 13 to 15 range, written and treated as a child soldier rather than an adult operator.
