@Tersione I was totally thinking that myself. If she still has just the right amount of feminine mannerisms (i.e. she's not COMPLETELY manly) combining that with loud obnoxiousness is actually a pretty decidedly unbeatable formula. I'm kinda hoping they're setting that very plot up for her. I can't help but see the chapter where he explains to his son that your vtuber persona needs to be a marriage of your genuine and ideal self as foreshadowing.
(Bit of a fun note to anyone reading who might not be aware: there is actually a whole GENRE of vtubers similar to this dad, except they more or less come straight out with it instead of trying to hide it. One of Natsuiro Matsuri's most infamous incidents was her lewding a loli one of these in Minecraft.)
