It's like a weird futuristic view of organ transplants: Ran's brain died while only Jou's body was injured in the accident, so to save Jou's life they put Jou's brain in Ran's body. Ran's body was still functional because sometimes the heart keeps beating for a while after the person's brain has already died.
The only thing left to do in those cases according to contemporary medicine is to pronounce the person dead, and maybe donate the still beating heart, but this manga explores the possibility of donating the entire body to someone else whose brain is fine while his body's days are numbered.
same here
when you explain it, it makes much more sense. i just think i didn't want to accept it because it's so damn depressing >.<
i do not understand this manga at all. wtf is going on?!? ran is dead but some guy named jou is in his body... yet he is still being called ran.. and someone else is now in jou's body?????
i don't even know..... someone get this manga together because it is all over the place.. fack. i need a drink.
