Yui began her career on Niconico (Nico Nico Douga) in 2010s-era Japan, when the platform became a breeding ground for digital influencers. With her blend of humor, relatability, and unfiltered commentary on daily life, she cultivated a loyal fanbase. Her work often blurred the lines between professional and personal, reflecting the demands of maintaining online personas in a hyper-connected world. The “Living Hell” reference in her title may allude to the emotional toll of constant visibility—stress from meeting fans’ expectations, navigating cyber-harassment, or the pressure to innovate in a competitive industry.
