Can you confirm that his brother is Christopher Daughtry, linked above? They aren't FB friends but that Christopher is linked to his mother.
I agree with what you're saying about his mom. She does seem like a very kind lady and her comments seem to disprove Akemi's stories about how his family tried to break him and Yalitz up.
At this point, my biggest concern is that, as discovered by
@crei, and as you mentioned, Akemi has at least one very young half-sister (Not gonna be linking to evidence of this or anything) and has talked plenty about being interested in both very young women and incest in the past, not to mention bragged (read: probably lied) about molesting a 14 year old who lived with him.
Does his mom
really understand what kind of person Damien is? Does she let him around the half-sister?
Also, do you know them personally? It's cool if you aren't comfortable saying if you do or not.
The only thing I might add are explanations for what things like shota, lolicon and CP mean.
