It seems you're referencing a phrase that may involve a misspelling or mix of terms. "Hentai" typically refers to a genre of anime/manga, and "Shinseiki no Ko to O Tomar" doesn't clearly match known works (perhaps a misremembered title like Shinseiki Evangelion or something else). If you're looking for a creative story based on that idea, I’d need a clearer theme or direction.
