Mugi Ienaga's Study With Me Stream Gets Sponsored by Chill With You: Lo-Fi Story
The sponsorship marks a rare direct brand partnership for a VTuber's study-focused stream, a format typically sustained by viewer donations rather than corporate backing.

VTuber Mugi Ienaga, a member of the Nijisanji agency, announced on May 30 that her regular "Study with me" streaming series has gained an official sponsor. The sponsor is the game "Chill with You: Lo-Fi Story," a work-focused adventure title developed by the studio Nestopi. The sponsorship will run from June 1 through the end of the month. Ienaga debuted in March 2018 as part of Nijisanji's second generation, originally presenting as a 15-year-old middle school student. Over time her character's age has advanced, and she now streams as a 22-year-old university freshman. She has cultivated a reputation within Nijisanji as a studious streamer, known for quiz show appearances and essays published on the note platform and, since November 2025, in a serial on the KADOKAWA web media Mekurimekuru. "Chill with You: Lo-Fi Story" is a game in which players join a literary-minded character named Satone for voice-call study sessions. It has received over 9,600 reviews on Steam with 98% positive ratings, earning a "Overwhelmingly Positive" status. A mobile version launched on iOS and Android on April 8, 2026.
Mugi Ienaga announced the sponsorship via a post on her official X account on May 30. She wrote that she was happy to have the support and looked forward to studying together with viewers in June, with further details to come later. The sponsorship period covers the entire month of June, making it a month-long collaboration rather than a single event.
Ienaga's "Study with me" streams are part of a broader trend of co-working or co-studying broadcasts on platforms like YouTube and Twitch, where the streamer works quietly on camera while viewers join to do their own tasks. Ienaga has leaned into this niche heavily, positioning herself as a studious streamer within Nijisanji. Her other intellectual pursuits include writing essays, and she has published a serial on KADOKAWA's Mekurimekuru web media since November 2025.
"Chill with You: Lo-Fi Story" is a relatively new title, having launched on mobile just weeks before this sponsorship was announced. Its Steam version has maintained a high approval rating, and the game's premise of a quiet, focused work session aligns closely with the atmosphere of Ienaga's study streams. The developer Nestopi is based in South Korea.
