>>552157I find it hard to believe Peko could go out for 3D events and such and manage to BS her mom out of it, or that Peko could have so much income coming in and her mom never bothered to find out exactly what she was doing to get it.
That being said though, if it was her mom, actually she wasn't completely in the dark; she had become basically certain that Peko was some kind of streamer or youtuber, but just didn't know she was a vtuber nor so successful. So that makes it somewhat plausible it was for real. Also it's not implausible to me her mom really would have such a surprisingly nice ara-ara voice - having a nice voice somewhat can run in the family, and Peko probably was gifted with one that is good for voice acting aka her wacky Peko voice.
