Development: AAbility: Erase all types of history.
For example
If Keine had a child she loved and cared for, erasing its parent's past history would mean the child would not be hers but instead its birth would be a mystery. This history will remain for only two people, the child and Keine. The birth of a child cannot be erased. As its existence is not "history".
But Keine wouldn't do anything this horrible...
