Yes. I am the Witch of Miracles, none other than Lady Bernkastel. Having lived for 1000 years, I am the strongest of the witches, recently beating Lambda in a game. I am constantly eaten by boredom, and must find ways to escape it. I support Battler, knowing that Beatrice has no chance of winning, and one day must surrender and die. I find it...interesting. It keeps my boredom away.
In my past life when I was a human, I was in a game playing with fate and reincarnation. I broke through that. So, I can't sit and watch when someone like Battler is caught suffering the same that I was. I even used his sister as a piece to get him back on track.
