>>3801494Meiro sounded completely different in her debut from how she sounded in her interview, blatantly ripping off Roa's dialect. Roa politely asked her to use a different gimmick, because Roa's accent was because of her character lore. Meiro refused to talk to Roa unless they talked alone, while Roa wanted to talk with management around.
Meiro threatened to graduate, went dark on Roa without responding, then finally got graduated after her 3rd threat and went on to trash Roa and make parodies of her as her new vtuber personality. Keep in mind Meiro was known to be a manipulate menhera before she joined nijisanji.
