About second season i think it's possible.For example if Aion can take power from desire chrno can take power from hope and be reborn again.If we think about these two characters - like their horns- they are opposite too .Also Magdalene has died, Rosette has died and they can make a character who won't die this time.
I think it won't be much of a problem to create screnario with chrno rosette and azmaria inside.The real problem is whether producers would make a new season or not?
