Killed Again, Mr. Detective?

For a detective who always cracks the case, Kisaragi is surprisingly unlucky in love — and in life. Every time he gets close to solving a mystery, he meets an untimely and often bizarre end, only to wake up in his own bed, alive and well, though with a nagging sense of déjà vu. It seems an unknown force is determined to keep him from the truth, no matter how many times it has to reset the clock. This endlessly looping conundrum presents a unique challenge for the perpetually perplexed Kisaragi. With each death, he retains a fragment of memory, slowly piecing together the larger puzzle of his own peculiar predicament. Can he break the cycle, uncover the identity of his killer, and perhaps even find a lasting romance before his next inevitable demise?
