VTuber Ironmouse is rocketing to popularity on the live-streaming service Twitch.

The Puerto Rican VTuber recently became the most-subscribed streamer on the platform, cinching the sought-after title following a subscriber-collecting subathon. She also boasts a follower count more than 1 million strong. As a VTuber — or virtual YouTuber — followers are only familiar with the animated version of Ironmouse, whose voice is provided by the real-life creator behind the account. The pairing of Ironmouse’s consistently popular streams and the virtual character’s charming personality aided greatly in her journey to the top of Twitch, where she’s been breaking records left and right.

Who is Ironmouse?

Ironmouse is a cute, pink-haired, anime-style VTuber whose account appeared on Twitch in 2017. In the years since, Ironmouse has risen high enough to compete with some of Twitch’s top streamers, raking in subscribers in the tens of thousands. She recently became the most-subscribed-to channel on the platform, a goalpost which she celebrated — along with her loyal fans — in a recent stream.

The popular streamer made a name for herself through several years of gaming-centric content, uploading streams of herself enjoying titles like 7 Days to Die in her early days and transitioning to more relaxed titles like It Takes Two in recent years. Her popularity has undergone a major boost over the last several months, following her arrival at 500,000 followers in mid-2021, according to Kotaku. Since then, her star has been steadily on the rise as the creator racks up fresh followers on a near-daily basis.

This is aided, in large part, by her streaming schedule. While many streamers struggle to maintain consistent release schedules, Ironmouse is hyper-focused on her Twitch presence. Much of her current popularity can be attributed to a recent subathon, which remained ongoing for a truly impressive amount of time.

Why is Ironmouse so popular?

As noted above, there are multiple factors behind Ironmouse’s Twitch success. She built her follower base for years before signing onto VTuber agency VShojo in 2020. Since then, she’s been a mainstay among some of Twitch’s most prominent streamers, varying uploads between a range of content types. Most of her content sees Ironmouse enjoying a game or chit-chatting with her followers, but it occasionally branches out into reaction videos or casual, rambling IRL content.

The sudden recognition behind Ironmouse has a lot to do with the VTuber’s subathon, which kept the streamer busy for right around a month straight. The subathon — a marathon stream intended to boost a creator’s follower count — started on Feb. 4 and concluded on March 7, according to Upcomer. Ironmouse presented the subathon with simple rules, stating that each fresh follower added during the stream would add 15 seconds to her stream timer. In total, she gained 171,818 followers over the course of 31 days.

The lengthy stream aided immensely in Ironmouses’s rise to fame and saw the chipper creator break several records along the way. Over the course of her ceaseless month-long stream, Ironmouse hurtled past massive creators to seize brand new records. By day 11 of her subathon, Ironmouse surpassed Miyoung “Kkatamina” Kim as the most-subscribed female streamer on Twitch and soon after cinched the record for third-most concurrent Twitch subscriptions in the entire history of the site.

In just four years, TikTok, the short-form video-sharing app, has gone from a popular fad to a Gen Z cultural touchstone. In the last year or so it’s become something else as well — one of the best things that can happen to an up-and-coming musician, especially one with eyes on the Spotify Viral 50.

And for one aspiring Atlanta artist with a penchant for sweaters and Cardi B, he owes a big debt to TikTok for making a splash on Spotify.

Lil Shordie Scott’s “Rocking A Cardigan In Atlanta” is currently in the Top 20 of both the U.S. and Global Viral 50 playlists on the streaming service. That’s almost purely on the weight of its TikTok presence, proving that the platform is becoming as indispensable to emerging artists as radio play was to what your elders knew as “rock ‘n’ roll.”

TikTok omnipresent and ever-changing dance trends have certainly helped a fair share of established names such as Megan Thee Stallion and Doja Cat remain on the popstar A-list, but it’s helped the careers of more than a few obscure acts as well. “How You Like That” by Blackpink, “Beggin” by Måneskin, and “Astronomia” by Chiky Dee Jay are just a few of the many songs that have had a spotlight shined upon them by TikTok virality.

In the case of Lil Shordie Scott — according to his YouTube page, he’s a “youngin from the southside of Atlanta with a different style and vision” — it took two months for “Rocking A Cardigan In Atlanta” to go from debuting on his SoundCloud account to becoming a TikTok dance jam.

The track seemed to take off, according to Scott’s genius.com page, following a cover video by TikTok user @runuppercy. The video, admittedly quite different from Scott’s flow, gathered over one million likes (and counting) and, more importantly, sent users in search of the original.

The song got another unexpected TikTok boost when Jenelle Evans, star of Teen Moms 2, posted herself twerking to Scott’s original version of the song following her revelation that she was suffering from fibromyalgia. In the video, Evans dances along to the song using moves that have gone viral in one of the platform’s many dance trends. Users across the platform have posted their own videos — generally featuring more than one person dancing— all following the same steps.

Of course, virality doesn’t guarantee last fame, but Lil Shordie’s fairly distinctive flow and vocalization, pitched many times above most of the raps coming out of Atlanta right now, may prove a key to success. (That piano intro’s pretty fantastic as well.)

Time will tell whether his time as a TikTok trend was a momentary supernova of infatuation, or if he’s here to stay in the firmament for a while.
