Quick Profile
Best Player Read
Do not turn unusual NPC behavior into a false alarm. Friendly characters are usually clues, not threats.
Use this page to separate character context from normal anomaly checks. That separation prevents wasted time during active shifts.
Appearance
Looks nearly identical to Ratthew, with visible eyelashes, a pink bow on her ear, and different eye highlights.
Behavior and encounters
Does not appear as a normal in-game NPC; her story is revealed through Ratthew's monologue and a hidden photo.
After Ratthew's late interaction, his key and note lead to the hidden Vault behind the Room 5 cat poster, where Rattina's photo can be found.
Read this character alongside the shift progression and events guide when the encounter is part of a run. A named character is not automatically an anomaly: use the anomaly checklist only for patient evidence and keep story clues tied to the character's confirmed role.
How to handle Rattina
- Follow Ratthew's late dialogue and collect the key and note
- Use the key in the Room 5 Vault route to find Rattina's photo
- Treat Rattina as a lore clue, not a character who spawns at the check-in window

A character you never meet
Rattina is Ratthew’s twin sister. She previously worked for Animal Corporation and disappeared without a trace. She does not appear as a normal in-game NPC, and her story is revealed through Ratthew’s monologue and a hidden photo instead.
That makes her entry different in kind from every other character page: there is no behaviour to read, no encounter to prepare for and no window check to run. The content is entirely the route that leads to her evidence.
The route to her photo
After Ratthew’s late interaction, his key and note lead to the hidden Vault behind the Room 5 cat poster, where Rattina’s photo can be found. The recorded tips follow that sequence: follow Ratthew’s late dialogue, collect the key and note, then use the key in the Room 5 Vault route.
This is the same chain referenced on the Ratthew page and in the Ratthew Key guide, so the three pages describe one route from three angles. If you are following it, the constraint is progression rather than detection — the interaction is late-game.
Do not look for her at the check-in window
The recorded guidance is explicit: treat Rattina as a lore clue, not as a character who spawns at the check-in window. This matters because the site has a strict habit of treating arrivals as things to inspect, and a player looking for Rattina in the admission queue will waste a shift waiting for an arrival that cannot come.
She is documentation of what happened to a former employee, and the correct interaction with that documentation is reading it.

Does Rattina appear in game?
No. She does not appear as a normal in-game NPC. Her story is revealed through Ratthew’s monologue and a hidden photo found in the Vault behind the Room 5 cat poster.
How do I find Rattina’s photo?
Follow Ratthew’s late interaction to get his key and note, then use the key on the hidden Vault behind the Room 5 cat poster. The Ratthew Key guide covers the same route.
Who is Rattina?
She is Ratthew’s twin sister, a former Animal Corporation employee who disappeared without a trace, which ties her to the corporation’s hidden work.
