Antler-like horns on both men and women have been a symbol of being cucked across Western cultures since the 15th century, see https://en.wikipedia.org/wiki/Cuckold#Metaphor_and_symbolism and >>1285
You know that thing where kids secretly hold up two fingers behind another kid's head in photos as a kind of teasing? They don't know it, but the original insult's meaning was of giving someone else "horns" i.e. implying they'd been cucked.
There's no such meaning for Japanese artists, of course - they just put horns on girls because girls with extra things on their heads are cute.
We're just enjoying a bit of unintentional symbolism since we cuckqueans are willing hosts to our horns. For example, take pic related - a lovely unintentional pun.
