Just like your average noble family in your average isekai.That is some fucked up family dynamic.
It's like typical filler in shonen action anime. Just before the heroes defeat the current opponent, they get their tragic backstory flashback, mostly to pad for time so the anime doesn't overtake the manga, and after that no one cares.Haha, everybody gets a backstory! It's like Oprah, but even fewer people give a shit
Normally it's an Asian that gets a demon parent lolDamn the demon got an asian parent.
