In the OVA sequel, we are introduced to Louise who looks exactly like Lise in the Red Garden TV series. Lise is last seen dying the Animus death of turning into ashes on Roosevelt Island, so it is generally taken that Louise is a reincarnation of Lise. Later on, Louise revealed her identity as an android. (Gasp!)
How could Lise, a human girl turned Animus infected with the cursed Doral blood, reincarnate as an android? What happened during the 300-year time span between the end of the TV series and the beginning of the OVA to have caused this inconceivable transition in Lise's identity?
