You fool, you absolute dingus, she's 5000 years old. Haven't you been paying attention? All kidding aside, due to the endless time loop nature of the setting, all characters can be hand waved as thousands, if not millions, of years old. Furthermore, if they're going to remove it due to chinami, they've already had the opportunity to do so, but they haven't. But the biggest reason why I believe the game won't get taken down is because, as long as it's up, the site lives rent-free in selebuses head. And I think the moderators get a kick out of that.
