There must be a reason why they covered his face when he killed her. And if he really reincarnated there too, I think there's a high chance he remembers everything too.
Well I forgot about that but reading your comment made me think... Maybe the shadow thing that talks with the emperor? Or maybe Chris himself, I love Chris but we did saw him with a shadow like this too at some point
I wonder who's the creep who killed her?
I'm pretty sure that they're also in this universe.
