huh? uhmm its friction based on someone's imagination and art style. This isn't some illegal po** site featuring children in a locked space. It clearly stated the age of each character and their occpation. 21st century and Earth's world views are thrown out the window when it comes to friction more so anime/manga.
most attack on Titan characters were all teenagers at 12 -19 commiting mass genocide, same things seen in Naruto or the cute Princess principal and adults having s** is what stroke your conscience?
LOL
if you're gonna be prejudice pls go all the way through cause i bet you enjoyed Naruto and AoT or you're just being a hypocrite...a two faced bas****
