Now that i think about it after rewatching S1, Nanatsu no Taizai is so fucking problematic
Meliodas is 3000 years old and Elizabeth is 16, you could even say he groomed her
then you have King who is also old asf, meeting young kid Diane, you can't say King groomed Diane because he erased her memory at least, but that shit is coming back for sure and then it's basically the same thing
and of course, Meliodas keeps touching their bodies all the time
