I would say Alan is about 30 something considering he was in his late teens/early 20s when he started looking for the sins, this is roughly ten years after that so I would say he’s not super far in age with them since they weren’t super young kids to begin with, and he’s definitely not physically old enough to actually be their dad (but this is just my guess anyway)
Think he’s about 10 years older than all of them except for the priestess as she’s a few hundred, if not a thousand years old. I just remember this vaguely though. Right now, MC should be in his early 30s, if not 30 and the others (except for the priestess/saintess), are in their late teens to early 20s.
Did I miss somewhere anyone's age was mentioned, I know Alan is supposed to be adult age and the kids are younger than him by enough for him to still consider them kids but I'm not sure how old anyone is actually supposed to be. Soelrang said "the age difference isn't that big" but like? 5 years? 10?? Sometimes Deus looks older than Alan, it's confusing.
This doesn't change anything and I'm glad Alan sees himself as the kids papa, just real curious.
