Maisaki Berry | Aidoru | アイドル
Aidoru アイドル means 'Idol' in Japanese.
She does almost exclusively karaoke; the song that did it for me was her 75k stream; she sang Walküre's Ikenai Borderline.
That particular rendition on that stream, I like to show people who come to my place;
I enjoy watching their jaw drop when they hear her break into song, that one in particular lol.
You'd think I watch a lot of Hololive because of how much I draw them, but alas, that is false; I like karaoke streams, almost exclusively.
