So, in the Indonesia vtubing sphere side of things, there's something that recently just came up that causes me to question something, but let me explain the context.
Back in May (it's already June on my end, bear with me), ID vtuber from JKT48V aka Vtuber sidebranch of ID Idol group JKT48, Kanaia Asa announces her graduation on the 5th May, with the graduation date happening on 31st May local time. The Graduation itself was more or less normal and she was able to do stuff as JKT48V member up and including one last mini concert with her two other genmates Tana Nona and Pia Meraleo on ID's Comic Frontier event last week (the same event where a Iofi crossdresser man-handle a convention thief).
What's interesting about it is that, on the same day after Kanaia Asa officially graduates and no longer doing stuff as Kanaia Asa, her PL account casually quote-replied to JKT48V's official announcement about Kanaia's graduation and openly stated that she is the one behind Kanaia.

ID TL tl;dr: Pretty much just her introducing herself as the one behind Kanaia Asa and her basically thanking her genmates, JKT48V and its staff, all that stuff.
My question is that, has this kind of thing has happened in either JP or EN vtubing sphere? As in openly mentioning who they are right after graduating without so much as subtle hints or 'nudge nudge will come back hint hint' kind of thing?
