I both love and hate that Teto is more popular now. I love it since Teto has been my favourite since I was a kid, and she's gotten some great songs recently. However, I also think this will end with new fans ruining Teto like they do with so many characters. One thing I can see happening is people finding out that she's a chimaera and using that as an excuse to say she's some sort of representation that she clearly isn't.
I just can't stand people who act as if they are the number one fan, well, only knowing about it for a fraction of its lifetime. Nothing is wrong with being a new fan as long as they don't expect it to bend over backwards for them and act as if they are better fans than other fans, but I've seen it time and time again that people don't, it's as if being new is bad and they must be the number one fan.
The biggest giveaway for this type of fan and something I tend to hate is when they get shocked or upset about something in the fanbase that they don't agree with, and either say others are wrong, or try to change it and say this needs to go.
