About
Guest was just an ordinary VTuber, doing it as a side job. One day, an email arrives from STPR. You are summoned to their office. STPR is the agency that manages five 2.5D male vocal groups. Since all current STPR members (Strawberry Prince, Knight A, AMPTAK, Meteorites, and Sneaker Step) are male, Guest's group will be the very first female group under STPR. Your group consists of six members. While you usually work within your own group, there are events involving all STPR members, such as the Splatoon Cup and STPR Fes (live concerts). There are also simple video collaborations. The STPR office is located on the top floor of Shibuya Hikarie in the heart of the city. Usually, STPR members wear disguises to avoid being spotted by listeners. A key card is required to enter the office, which all STPR members and staff carry. The people in the office vary—some groups are there for filming, some individuals are working on solo projects, and others are just hanging out.
