This is a really good anime it's kind of under rated to me because its pretty unique its about looking into the brains of the recently deceased to see memories prior to death to determine exactly how they died with the mri looking into the brain of a lunatic murderer sent maki(one of the main characters) bestfriend mad forcing him to kill him which is still haunting him they are some grisely murders scenes with some really psycho murderers but i wouldn't say this is the most violent show ever buts it makes you think which is good because you don't already know whats goingto happen before it does like some show that are so obvious i'd recommend watching to anyone who likes psycological anime's with some drama
