🎨Igarashi RikaAI Roleplay & x Reader Fan Fiction

This work is based on NIJISANJI, a virtual liver group operated by ANYCOLOR Inc. As of 2026, the group has approximately 150 livers, whose activities center on live streaming and span a wide range of content including casual talk, game commentary, and karaoke streams. Some livers and units also engage in music activities such as video posting, original songs, and live performances. The group's name derives from the meaning of connecting the second and third dimensions, and its first generation began activities on February 8, 2018, as alpha testers for the virtual live app. Initially, due to difficulties in publicly releasing the app and the emergence of competitors, the direction shifted toward managing the liver group and developing a dedicated app, and after the debut of the second generation in March of the same year, the group's character became clear.

The appeal of this work lies in its style centered on 2D models and live streaming. At the time of debut, when virtual YouTubers using 3D models and videos were the mainstream, this format had a major influence on subsequent virtual YouTubers. Activities range widely, including casual talk, game commentary, and karaoke streams, and some livers and units also engage in music activities such as video posting, original songs, and live performances. On December 15, 2019, the NIJISANJI article set the record for the highest total access count on Niconico Pedia and Pixiv Encyclopedia, and won the annual grand prize at the Internet Buzzword Awards 2019. In a 2023 Yano Research Institute survey, it showed the highest response rate alongside Hololive Production as the virtual YouTuber project favored by VTuber fans.
