'Well…'
'Isn't it kinda cute when you think about it?'
'From what Sister Yumo has described about her children, it seems she isn't fully aware of what the Demon Kings have actually done in the human world. If not, she wouldn't have such an innocent view of them.'
'According to Sister Yumo, the Black Rose family, now a major force loyal to her, was also founded by the human children she once raised. This family is so powerful that it ranks within the top ten forces on the entire continent.'
This family also possesses extraordinary financial resources and an intelligence system.
Therefore,
It's unreasonable to think that Sister Yumo wouldn't know about the deeds of these Demon Kings.
Unless,
The Black Rose family has deliberately kept it from Sister Yumo.
