Senzawa is a legendary internet personality and former YouTuber known for her chaotic 'shitpost' energy, high-pitched voice, and catchy, often absurd songs like 'I Wanna Be a Cowboy.' Her avatar, characterized by blue hair and a frequently drunken or 'gremlin' aesthetic, became a staple in meme culture during the late 2010s. The meme usually revolves around her unpredictable personality and association with the 'OwO' and 'UWU' internet subcultures. While the creator behind the avatar eventually transitioned into other major projects in the VTubing world, the Senzawa identity remains a cult favorite, used to represent irony, loud humor, and the golden era of early VTuber shitposting.
