Note 1: Do not harass anyone! It does not help the victim, and potentially just can garner sympathy to whoever the perpetrator is.
Note 2: Mafumafu did not specifically name Mikeneko, however everything about A-san lines up perfectly. He probably can’t name whoever is she as he might have had to sign an NDA. So unless there’s coincidentally another female creator with very similar life…

Long story short: After an article in a Japanese magazine have revealed his marriage, Mafumafu had to go explain some further details on his situation. He detailed his relationship, and the abuse he received, especially the extreme jealousy.
During the divorce settlement, multiple people, including A-san have harassed Mafumafu as a cheater and domestic abuser. There’s also some accusations that Mafumafu have killed A-san’s blind cat, which hurt him the most.
Since events are matching up with A-san being an online personality who’s returning in a new form and the death of a blind cat, people are believing she was Mikeneko. One another thing is, when Mikeneko worked for Hololive and the whole drama has just started, Hololive only said the talent’s private life is up to the talent, and did not deny accusation of the two dating and/or being married. https://twitter.com/ziltoid1991/status/1751260196494582165
