How does the demons' extremely long lifespan affect their everyday life, growth, relationships, and such?
I feel like a 2000 year old demon should have a lot more knowledge and experience than a 20 year old mortal, especially when demons have their own internet.
I have a lot of questions regarding demon longevity, but I think this one sums up most of them.
a bunch of my netherworld stuff is based in disgaea lore! my simple answer is just that the numbers are inflated in the netherworld, so my demons are not literally 2000 years old. the disgaea explanation is that time passes differently in the netherworld, but i think in local time it still feels the same. that's why i say it's just inflated.
