i will say that i tent to avoid calling waifu characters that i enjoy but are depicted as "childs". Even if they are legal. Like i also love Konata and Kiragami from Lucky Star, or Gawr Gura from Hololive or my Favorite Fire emblem character is Lysithea. They are in my favorite characters of all time for sure, but not my waifus. But i won't call them "waifus" because of the child/loli factor drives me away. But i will say, some people are really "hard no" of talking about characters that are "not legal", and i don't really understand why. I mean they are fictional at the end of the day.
But i will keep it there. I don't want to start a debate like the ones that appeared a lot when i was using that shitstorm website that tends to cry about everything (twitter):)
