A costume shared by all NijisanjiVTubers (including Virtuareal), used at Nijisanji Anniversary Festivals (also called Nijisanji Fes or NijiFes).
With a theme of a school festival, members are sorted into one of seven classes named after the traditional colors of the rainbow. Each class wears a matching short-sleevedprintt-shirt. The rest of each member's version of the costume is personal to them, often based on their default costume. The NijiFes 2023 key visuals add a white jacket with multicolored paint splats.
