i did some researchs , and the results are :
https://en.wikipedia.org/wiki/Gilles_de_Rais
Gilles de Rais was a French male knight and lord .
he was convicted of being a prolific serial killer, r@pist, and occultist.
He confessed to abducting, torturing, and murdering an estimated 100 to 140 childrens .
he utilized his servants , like the red baron , to lure childrens to his various castles .
The victims were subjected to horrific physical abuse, ritualistic torture, and murder .
He engaged heavily in the occult, , just like okarun does , admitting to the invocation of demons and yokai , heresy, and alchemy , in an attempt to acquire forbidden knowledges and powers .
Because of the systematic and ritualistic nature of his murders, he is frequently cited as one of the first documented serial killers in recorded history .

i dont understand what the smart brain of the mangaka was thinking .
giving the name "Gilles de Rais" to an under-age innocent good girl , is dumb .
