>>713785830Soulmate is referring to being a demon's knowledge
And like mc x aogami faggotry, lolifags and incestfags see it as romantic, even if she's not related or an actual loli
Aogami's whole relationship is "young man/shonen is my knowledge, I have to watch over him and protect him" he then comes to learn and respect humanity more as the story progresses. Zero homo shit. All of that is head canon. Amanozako's feelings are the exact same.
If there was any sexual or romantic overtones, it would be outright stated, like in various demon entries like succubus, mokoi or incubus
