my theory: he has the skill to store stuff inside his body (like an inventory) so he probably stored body limbs and when he “exploded” he threw out the body parts and jumped away. in the story you did get to see that kasar jumped into water while he “exploded” (they were standing on some sort of tower surrounded by water)

I was in a hurry to read this, read it in the middle of a meeting haha but I read the first half quite some time ago. And while it's true that everything was literally explained, maybe I went over this particular part?
What was it about kasar being introduced as 'immortal' too? That part about how he blew up and played dead. How did he survive that again?
