https://www.animenewsnetwork.com/interest/2020-10-24/nijisanji-vtuber-agency-releases-details-regarding-termination-of-kingyozaka-meiro-contract/.165483Yuzuki Roa and Kingyozaka Meiro had the same speaking quirk (like if holo had 2 nanoras or degozarus). Roa (senpai) wanted to chat with Meito about this, though she didn’t necessarily want Meiro to stop using the manner of speaking. Meiro declined, then wanted to graduate because of the issue, then changed her mind about graduation, later got suspended for leaking confidential stuff, got suspended, wanted to graduate AGAIN, and changed her mind about graduating once more. She eventually got fired after a second information leak, and to this day people blame Roa for that, who has now been on indefinite hiatus for the past 3 years, because she’s fighting a court case against antis.
TLDR – Roa antis are like fandeads, except much worse
