@Liquidxlax There actually are quite a few where the reincarnated isekai kids are pedophiles, since they have the mind of an adult (in my case, I'm separating the mind, body, and soul, where mind is the actualization of the person's soul based on the body, the soul is the memories, and the body is the biological age, in case of pedophilia argument, the mind's age is most important). And there are quite a few that are pedophiles anyways regardless of biological age of the body (18 for most countries, 13 for japan's age of consent which is the lowest amongst 1st world countries, but I guess that means, they don't consider it pedophilia since 13 is age of consent, which is well within the majority of people on earth's moral scale that it is waayyyyyy too young, and some may not have even started puberty yet). Example: Mushoku tensei. The MC was a stereotypical middle aged anime/manga otaku and even though he had a body of a child, he had the mind of a middle aged man, and was still basically a pedophile, since his mind and soul were independent of his body's biological functions.
Basically, regardless if they are in the body of a teenager (or a child for that matter), if they have the experience of an adult and still want to have the sex with the underage kids, they are pedophiles regardless. I mean, they have ones where the babys are lecherous after hot girls, where all they should be thinking is basic instincts cause they have the body of a baby.
Anyways, IMO, if they have the mind of an adult, and they lust after kids, they are fucking pedophiles, regardless of how old their bodies are. If they have the soul of an old man, a mind of a child, and a body of a child, they shouldn't be lusting in the first place cause they haven't hit puberty yet. But considering age of consent is 13 in japan, its not pedophilia....
