The Ambiguous Identity: Unmasking Anya Mouthwashing's Last Name And The Fan Theories

As of December 17, 2025, the question of "Anya Mouthwashing's last name" remains one of the most intriguing and debated mysteries among fans of the 2024 psychological horror game, *Mouthwashing*. This character, a key figure in the unsettling narrative aboard the Tulpar freighter, is officially known only by her first name, Anya, with her full identity intentionally obscured by the game's developer, Wrong Organ. The ambiguity stems from a blurred and cryptic ID card visible in the game, which has sparked multiple, compelling fan theories about her true family name. The search for a definitive answer has led to a deep dive into the game's lore and visual clues, ultimately revealing that the name is likely a deliberate piece of meta-commentary rather than a traditional surname. Understanding the different theories—ranging from a simple placeholder to a subtle Japanese reference—is essential to grasping the full scope of the character's mysterious background and narrative significance within the game's disturbing universe.

Anya (Mouthwashing) Character Profile: The Nurse of the Tulpar

Anya is one of the two tritagonists, alongside Daisuke, in the critically acclaimed 2024 psychological horror game, *Mouthwashing*. Developed by Swedish studio Wrong Organ, the game places players on the Tulpar freighter, a spaceship where Anya serves as the crew's nurse. Her role extends beyond medical care; she is also responsible for conducting the psychological evaluations of the other crewmates. Her character is central to the game's themes of isolation, psychological distress, and the breakdown of reality. Fans have noted her role as a mother figure to the protagonist, Curly, which is subtly reinforced by the fact that the name "Anya" in Hungarian means "mother". She is also confirmed to be pregnant during the events of the game, adding another layer of depth to her protective and nurturing, yet often unsettling, presence.

The Three Main Theories for Anya's Last Name

The intense curiosity surrounding Anya's last name stems from a specific in-game asset: her ID card. The text in the surname field is highly illegible, leading to a fascinating split in fan interpretations across Reddit, Steam forums, and dedicated fan wikis.

1. The "NoName" Consensus

The most widely accepted and likely canonical answer among the fan community is that Anya's last name is "NoName".

This theory suggests that the developer, Wrong Organ, deliberately wrote "NoName" on the ID card as a meta-commentary on the character's ambiguous identity or as a simple placeholder that was never intended to be a real name. It aligns with the game's unsettling and often surreal nature, where traditional details are frequently obscured or distorted. Close examination of the blurry text has led many to conclude that "NoName" is the clearest, albeit unconventional, reading.

2. The "Musume" Speculation

Early in the game's release, before the "NoName" theory gained traction, many fans speculated that her last name was "Musume".

The Japanese word *Musume* (娘) translates to "daughter" or "girl." This theory gained popularity because the ambiguous text on the ID card bears a resemblance to the Japanese characters or a transliterated version of the word. Given that *Mouthwashing* is a game that relies heavily on psychological and cultural subtext, some fans believed this was a deliberate, subtle clue about Anya's own familial background or her relationship to the other crewmates. However, this interpretation has largely been superseded by the "NoName" reading.

3. The "Chisome" and "Jibberish" Interpretations

Other, less popular theories exist, highlighting the true ambiguity of the visual asset.

• Chisome: One notable theory proposed the name "Chisome," based on a specific reading of the ID card's font and blur. This name, while less common, shows the depth of investigation fans undertook to solve the mystery.
• Jibberish: The most dismissive, yet arguably accurate, description is that the last name is simply "actual jibberish". This view suggests that the text was intentionally rendered as nonsensical or illegible to maintain the character's enigmatic nature and prevent a definitive answer, forcing the community to speculate.

Why the Last Name Mystery is Crucial to Mouthwashing’s Lore

The intense focus on Anya's last name is not just about trivia; it’s integral to the narrative style of *Mouthwashing*. The game thrives on ambiguity, unreliable narration, and psychological horror, often leaving key details open to interpretation. The likely answer, "NoName," serves a powerful thematic purpose. In a game where the characters are trapped and their identities are stripped down to their most vulnerable states, having a main character whose legal identity is literally "NoName" underscores the themes of depersonalization and isolation aboard the Tulpar. It suggests that her identity is defined by her role—the nurse, the mother figure—rather than a traditional family lineage. This deliberate lack of a surname makes Anya a more universal and perhaps tragic figure, whose personal history is less important than her immediate, terrifying circumstances. Furthermore, the ongoing debate itself is a testament to the game's success. The developer, Wrong Organ, has created a world so rich in subtext that a single, blurry texture on an ID card can generate hundreds of hours of community discussion and analysis. This kind of open-ended storytelling is a hallmark of modern psychological horror, and Anya's ambiguous last name is a perfect example of how small details can create massive topical authority for a game. In conclusion, while fan theories like "Musume" and "Chisome" are compelling, the most credible answer to the question of Anya Mouthwashing's last name is that it is intentionally "NoName," a powerful narrative device that enhances the game's atmosphere of dread and existential uncertainty.
