“VTuber Rina Tennoji” Set to Appear on YouTube

LoveLive! Nijigasaki High School Idol Club's IT Team is featured in the three-part YouTube series

The YouTube channel of the LoveLive! School idol project series will premiere three videos featuring Nijigasaki High School Idol Club's Rina Tennoji taking on the VTuber challenge together with her colleagues in the IT Team (Setsuna Yuuki, Shioriko Mifune).

The official LoveLive! Series website lists the schedules for the following videos (times in JST):

Chiemi Tanaka, who plays the role of Rina Tennoji in the LoveLive! Nijigasaki High School Idol Club game and anime, will be reprising her role for this series.

This is not the first time anime titles produced videos using methods which can be considered similar to VTubing. ONE PIECE FILM RED released a six-part "UTA Diary" in line with the movie's release.
