I totally agree with you that fanservice in general sucks and just ruins immersion, don't get me wrong. Also, I don't watch this show so I don't have a stake in it. Just wanted to clarify that so you understand there is no hidden agenda in my words. I literally mean what I wrote.

All I am saying is, from the very start, "loli fanservice is not pedophilia." The term pedophilia as understood by many people is completely wrong. 2D lolicon fanservice or even hentai is not pedophilia, even if the character is indeed pubescent.

So let's say you are correct and that character is indeed pubescent, that is still NOT pedophilia because 1) the MC is not primarily or exclusively attracted to prepubscents, and 2) this is not real but anime. You can argue that you meant the MC as a character went full pedo, in which case I will give up point 2 but point 1 still stands.

I'm arguing for accuracy, nothing else.
