/vt/ - Virtual Youtubers

Judging by the very limited insight we have into who they are beyond their characters, Botan is the only one that comes to mind. Mio too maybe. If only because they seem to be comfortable enough with themselves not to load their partner with unreasonable expectations.

Introverted, shy girls may seem like a good choice, but they're not. They'd quickly grow bored of (You) because they'd realize they can be a dull nerd by themselves.
Ina is the best example of this, (You) think you'd be great together because you're both nerdy and quirky, but what she really wants is a normal dude, preferably one who doesn't even know what the word "gacha" means.
