Nijisanji VTuber Mugi Ienaga’s study-focused live streaming project “Study with me” is sponsored by Nestopi Co., Ltd., promoting “Chill with You: Lo-Fi Story”.

On May 30th, Mugi Ienaga, a VTuber belonging to Njisanji, announced that her study stream project, “Study with me,” has been sponsored. This marks the first instance of a study stream by a Njisanji VTuber receiving sponsorship.

The sponsor is Nestopi Co., Ltd. Their work-in-progress adventure game, “Chill with You: Lo-Fi Story,” will be sponsoring the distribution. The sponsorship period is one month, starting in June 2026.
There will be no major changes to the format of the study streams, and there will be no ads interrupting the study sessions. Lo-Fi background music from the game can be used in the opening and ending sequences, and sponsor names will be displayed in the on-screen text. He also said, “I wanted to broaden the base of VTubers with what I could do,” and expressed his joy at the announcement.

Ienaga Mugi is a VTuber belonging to Njisanji who debuted in March 2018. To date, she has been active in various ways, including conducting long study sessions with her viewers and writing essays for a web magazine.

Chill with You: Lo-Fi Story is a work-based adventure game where you study and do desk work while “working on the phone” with Satone, a literary girl. As you set a Pomodoro timer and work, Satone will work alongside you, bringing you closer to her. You can freely combine Lo-Fi music and ambient sounds to create an environment conducive to concentration.


In conjunction with this announcement, Chill with You: Lo-Fi Story has been updated. Spring and summer outfits have been added to Satone’s closet. Satone will change her outfit every day according to her mood. Also, starting June 2nd, a poll will be held on the official social media accounts to find out which outfit you would like to see implemented next.


Additionally, five new merchandise items went on sale at POP @P SPACE -AKIHABARA- on May 30th. The five items are stickers, acrylic keychains, bromide prints, desk mats, and tapestries, some of which feature new illustrations.
