im rereading this and idk why but i feel like it wasnt a human that stabbed him in his past life but idk
yh it was a war between demons monsters and humans so it was most likely a demon
In my case i feel like there's some time travelling/parallel world twist going on in the plot. Like the heroes could be him & his friends and the stabber is connected to him...lol is that crazy or what?
