Who is Cayu?[]

Cayu is a long-standing figure within the VRChat community, active since early 2017. Widely recognized for their skills as a mentalist and social manipulator, Cayu became known for their sharp insight into people and situations, often blurring the line between performance and genuine psychological reading.

Throughout their time in VRChat, Cayu underwent multiple name changes and reinventions, a reflection of both personal growth and necessity. Their ability to read social spaces and navigate complex communities earned them both respect and notoriety.

Following a well-known conflict with the München staff a prominent VRChat community group Cayu withdrew from the public eye, going into hiding for several years due to escalating tensions and controversy.

In recent times, Cayu has returned to the scene under the name tinysmoll, reclaiming their place within the social fabric of VRChat. While their approach remains more reserved and calculated than in the past, their legacy as a mentalist and influential figure continues to precede them.

In late 2025, Cayu transitioned once more this time into the persona of BelphegorMstar, an identity reflecting their acceptance of stillness, spiritual exhaustion, and gentle rebellion against productivity culture. This transformation symbolizes letting go of their former siren self and embracing the beauty of calm, patience, and rest.

Personality[]

Other users often describe tinysmoll (real name Cayu) as someone who operates with a calm, deliberate presence, the kind of person who doesn’t need to raise their voice to leave an impression. In social spaces, Cayu is known for being highly observant, often reading the room long before speaking. They’re not the type to chase attention, but when they talk, people tend to listen. They have a dry, sometimes sarcastic sense of humor that catches people off guard, often delivered with a straight face. Many who meet them describe their vibe as quietly sharp, someone who’s easy to get along with if you’re genuine, but hard to fool. Despite their history with mentalism and social manipulation as performance art, Cayu is respected for their clear boundaries and honesty about their intentions. They don't play games with trust outside of roleplay, and those who know them personally often mention their loyalty and down-to-earth attitude. Creatively, they have a reputation for being ritualistic and disciplined, whether it’s in how they build their avatars, run their worlds, or engage in roleplay. Their style blends surreal aesthetics with cyberpunk influences, often reflecting themes of isolation, personal freedom, and subtle rebellion. They're not loud. They're not flashy. But they’re the kind of person who always seems ten steps ahead moving in silence until they decide to leave their mark.

Recently, as BelphegorMstar, they’ve leaned further into a slow, deliberate presence an almost divine calm that turns sloth into art. They approach everything with languid precision, showing that rest itself can be an act of creation.

Cayu's History[]

Before VRChat[]

Before entering VRChat, Cayu was an active member of the brony community and a dedicated Final Fantasy XIV player. Their early years were shaped by frequent visits to conventions, where they discovered Virtual Reality. After acquiring their first headset, they explored various VR titles before settling into VRChat, a platform that would eventually define their online presence. Additionally, Cayu worked as a convention steward, ensuring safety and organization at events.

Early Days in VRChat[]

Cayu's early days in VRChat were chaotic and exploratory. Initially searching for quality My Little Pony avatars without success, they began using public world avatars. It was during this period that they met Axivity, a notable VRChat figure who mentored them in avatar creation and VR content. Inspired, Cayu began creating VRoid avatars for their Twitch streams, eventually uploading them into VRChat. Their streams became known for mentalism, using psychological tricks to influence users into saying or agreeing to bizarre things, always prefaced with disclaimers about context and intent. Though illness prevented them from reaching peak popularity, Cayu remains an occasional streamer, now using their voice and showing their real-life appearance rather than remaining mute.

The Meme War of 2018[]

During VRChat's infamous 2018 "Meme War" marked by the rise of Ugandan Knuckles Cayu distanced themselves from the popular meme culture, instead joining the Kanna Gang, a group centered around Kobayashi-san Chi no Maid Dragon’s Kanna Kamui. At the time, they were still a mute both in-game and on stream.

Avatar Creation[]

In 2019, Cayu began creating their own avatars, focusing on original femboy models built from scratch in Blender. Learning primarily from the "Blender Donut Tutorial," their early models reflected a drag-and-drop 2.0 style but stood out for their quality and optimization making high quality femboy avatars accessible within the "Poor" performance rank, rather than "Very Poor," which was common for detailed models at the time. This led to their avatars becoming widely adopted in the mainstream VRChat community.

The COVID Era[]

During the Crasher Wars of 2020 when malicious users weaponized crash avatars Cayu’s friend group disbanded, including distancing from long-time mentor Axivity. Roaming worlds solo, they met TadayoshiVR, a streamer known for herbal discussions and VR lifestyle content. This new connection led to a distancing from their original circle a decision they later expressed regret over.

Post-COVID and Setbacks[]

In 2022, Cayu ended their relationship with TadayoshiVR after discovering issues of trust and loyalty. This separation resulted in significant personal and professional loss, as their combined Unity studios were dismantled. Consequently, they shut down their Gumroad and Booth storefronts, unable to maintain their avatar offerings. That same year, Cayu participated in research studying the effects of VR on Functional Neurological Symptom Disorder (FNSD), which they were experiencing at the time.

Present Day[]

Present Era: BelphegorMstar and the Sin of Sloth[]

In 2025, following a long period of introspection and recovery, Cayu underwent a profound personal and creative transformation. Having spent years embodying the siren a symbol of allure, pain, and endurance they chose to release that chapter and embrace something softer, slower, and more self-honest: the sin of Sloth.

Now known in VRChat under the name BelphegorMstar, Cayu personifies the celestial embodiment of rest and stillness. This change wasn’t a retreat, but a conscious decision to reclaim peace to build an identity that honors both weariness and grace.

Their VR presence now revolves around tranquil worlds, soft ambient spaces, and avatars inspired by Belphegor from Helluva Boss, fused with their own androgynous siren essence. The result is a style they call “holy sloth” divine lethargy dressed in velvet light.

In this new phase, BelphegorMstar uses their avatars and art to explore the beauty of stillness, the luxury of calm, and the sacred permission to rest. While the name tinysmoll remains part of their legacy, the BelphegorMstar era marks a creative rebirth — one focused on quiet decadence, surreal tranquility, and self-acceptance.

Notable Achievements & Legacy of Cayu (tinysmoll)[]

Early Pioneer of Optimized Femboy Avatars (2019–2022)[]

Cayu is widely recognized for creating some of the first high-quality femboy avatars in VRChat that balanced custom modeling with performance optimization. At a time when most high-detail models fell into the Very Poor performance category, Cayu’s avatars stood out for their accessibility — maintaining visual fidelity while remaining in the Poor or Medium ranks.

This design philosophy contributed to the mainstream adoption of femboy avatars within VRChat, moving them from niche communities into broader social spaces.

Mentalism Performance & Social Engineering Streams (2018–2020)[]

Through their early VRChat streams, Cayu became known for mentalism-style performances — manipulating conversations, predicting responses, and leading participants into comedic or bizarre scenarios. These acts were always accompanied by ethical disclaimers clarifying the performative nature of the interaction.

This unique style of content positioned them as one of the few VRChat streamers blending entertainment with psychological skill, influencing later performers within the mentalism and VR social engineering space.

Participant in VR Medical Research (2022–Present)[]

Cayu has participated in multiple research projects studying the effects of Virtual Reality on mental health — particularly regarding Functional Neurological Symptom Disorder (FNSD) and PTSD.

Notably, they are listed as Subject 7 in an ongoing research project focusing on the long-term psychological effects of extended VR exposure.

Their involvement has contributed valuable real-world data toward understanding the therapeutic and harmful potentials of immersive VR environments.

Worldbuilding & Immersive Systems Development (2023–Present)[]

In collaboration with EmilHauge, a respected VRChat world creator, Cayu is currently developing their own version of the Solar Cabins world. Their approach to worldbuilding emphasizes atmosphere, ritual, and immersive systems over gamification — reflecting their personal VR philosophy.

Additionally, their personal avatar systems (weather control, elemental effects, Sandevistan movement system) showcase advanced integration of functional systems into socially-driven avatars — blending roleplay immersion with technical prowess.

Historical Involvement in VRChat Subculture[]

Active participant in the Kanna Gang during the Meme War of 2018, resisting the dominant Ugandan Knuckles meme culture.
Survivor of the Crasher War of 2020 — a period marked by widespread malicious crashing within VRChat.
Veteran of multiple VRChat social circles, including time spent in both the underground mute scene and streaming circles.

VR Avatar Commerce & Distribution (Until 2022)[]

Prior to shutting down their Gumroad and Booth storefronts in 2022, Cayu provided custom and public avatar assets — contributing to the early economy of VRChat avatar creators focused on niche aesthetics like femboys and cyberpunk styles.

While their commercial presence has ended due to asset loss during a studio split, their avatars remain circulated in legacy collections and private archives.

Legacy Summary[]

Cayu (tinysmoll) remains a respected figure within VRChat’s history — particularly within the underground creator scene. Their contributions to avatar optimization, social performance art, VR research, and worldbuilding continue to influence new creators and performers within the platform.

Their style of immersive presence, technical self-reliance, and respect-driven social interaction has left a quiet but lasting mark on VRChat’s evolving culture.

Rumors & Myths about Cayu (tinysmoll)[]

Over time, Cayu has become the subject of numerous whispers, half-truths, and community-spread stories. Whether grounded in fact or inflated through years of retelling, these rumors contribute to the mythos surrounding their name in the VRChat underground.

The München Incident[]

One of the most infamous stories surrounding Cayu involves their encounter with the München group — a notorious VRChat circle known in their time for using modified clients with malicious intent.

München was widely feared in certain VRChat circles for their crashing avatars, asset ripping, and aggressive targeting of users — often wiping out public instances for their own amusement.

According to long-standing rumor, Cayu became a direct target of the München group during a period of high activity in public worlds. However, despite repeated attempts, they were unable to crash Cayu — allegedly due to their highly secure VRChat settings, client-side protections, and minimal avatar vulnerability.

Frustrated and unable to force them out like other victims, the München group is said to have blacklisted Cayu from their spaces, leading to the long-standing myth that they "went into hiding" — not from fear, but simply to avoid wasting time on a group whose tactics didn’t work on them.

To this day, the incident is seen as part of Cayu’s legend — someone who outlasted one of the most infamous malicious client groups of early VRChat history without bending or breaking.

The Silent Room Trick[]

Many VRChat users tell stories of encountering Cayu standing silently at the edge of public instances, unmoving for extended periods. Newer users who mocked or approached them would sometimes receive eerily specific comments about their avatar usage, world habits, or behavior — despite never having interacted with Cayu before. Friends describe it as social engineering. Others just say, "Don’t poke the ghost in the corner."

The Forgotten Avatars[]

Veterans in the VRChat avatar scene claim Cayu created several now-lost femboy models that never saw public release. These avatars were known for being extremely optimized, stylistically ahead of their time, and available only to a few trusted users. To this day, these models are treated as collector’s items, and it’s rumored that owners were explicitly asked never to share or reupload them. Their file names and designs remain part of VRChat legend.

The Mentalist Disclaimer[]

During their streaming era, Cayu became known for subtle and sharp mentalist routines — coaxing users into saying unexpected things during casual conversations or group interactions. Each act was closed with the now-iconic line:

"Anything said in this performance is not to be taken seriously or out of context."

Some viewers began using the phrase themselves, and it became a minor in-joke across certain circles in 2018–2020.

Allegations of Modified Client Usage[]

Because of Cayu’s deep system knowledge and ability to track users’ behavior so precisely, rumors occasionally circulated that they were using a modified client to access hidden data. Despite the speculation, no evidence was ever found. Long-time friends argue it’s simply a result of Cayu’s sharp perception and methodical world analysis — not anything malicious. They Claim to have never used any modified clients.

The TDA Model Controversy[]

While Cayu has always insisted on creating original avatars from scratch, some users have accused them of using TDA (Teto/Miku) base models during their early femboy avatar era. This likely stemmed from the similarity in body type and visual styling, but those familiar with Cayu’s workflow — rooted in Blender tutorials and personal rigging — confirm that their avatars were entirely custom. The claim continues to resurface in avatar-related discussions, despite being debunked multiple times.

The Debug Avatar Rumor[]

A select few VRChat creators claim that Cayu possesses a completely private "debug avatar" — a minimalistic, unlisted model used solely for testing shaders, physics interactions, and world systems. No public images or videos exist of the avatar. It is said to be devoid of detail — likely just a plain humanoid with internal toolkits — and only seen in empty developer worlds during off-hours. Its existence remains unconfirmed, yet the legend persists in closed creative circles.

VR Lifestyle & Daily Routine[]

Despite their heavy immersion in VR, Cayu lives by a structured and highly disciplined daily routine — blending creative work, real-life activity, and VR socializing into a carefully balanced lifestyle.

Each day begins with Cayu exiting VR shortly after waking up, leaving their avatar body hidden in a secluded, patron-only area within one of Artsy Glitch’s worlds — a habit reflecting their playful but private approach to virtual presence.

After grabbing an energy drink, they re-enter VR and head straight into work — spending around six hours a day in Maya focusing on creating 3D characters, primarily for VRChat avatars or other game projects. Their workflow is broken up with regular breaks every three hours — during which they go for a walk outside, accompanied by their cat Freya and two cockatoos, usually heading to a nearby park.

Following the walk, they spend about an hour flying RC helicopters — one of their real-life hobbies — before returning to VR. Lunch breaks follow the same pattern, with outdoor time and a meal before diving back into work.

After finishing their work for the day, Cayu takes another outdoor break before dinner. Evenings are dedicated to socializing in VR — visiting worlds outside of their usual home in Solar Cabins, meeting friends, or exploring.

Their night routine is carefully ritualized. After socializing, they exit VR to put on pajamas, change into their VR robe, and swap out all battery packs and powerbanks for their trackers and controllers. Returning to VR, they spend several hours watching YouTube videos, usually while snacking on Pringles and drinking Arizona Blueberry White Tea. This is their downtime — a quiet end to the day before sleep.

Before going to sleep in VR, Cayu removes the top clothing and glasses from their VR avatar — adding to their immersive habits — then checks their mail and Discord messages. They sleep fully immersed in VR, often within Solar Cabins.

On weekends, their routine shifts toward gaming for relaxation, spending time in titles like Skull and Bones, Final Fantasy XIV, World of Warcraft, or Euro Truck Simulator. Streaming sessions are done at random, depending on mood and energy.

Cayu is also a vaper and occasionally smokes weed — primarily to manage pain and relax during downtime.
