The new manga series from Kei Sanbe, the master of suspense behind Erased, plunges an innocent young boy into Tokyo’s criminal underworld, as he fights to keep his younger sister alive, and to return his soul to his own body!

Our protagonist awakes in a house he doesn't know-in fact, not only does he not know where he is, he doesn't know who he is. What he does know is that this unfamiliar house is empty, save for the body (and head) of a decapitated woman-a stranger, he thinks. He’s rescued by a woman, Shio, who calls him Iori"...but is that who he really is? And when she helps him hide the body without batting an eye, telling him to trust her...can he? Should he?"

When the charming young boy who moves next door turns out to be a psychopath who murders her little sister, Itsuki vows to fight the injustice which gave him a second chance at life while her sister lies dead. Blaming herself for what happened, she becomes a stone-cold cop who fears nothing to prevent others from living through a similar tragedy. But six years later, on the very same day the killer is finally set free, she finds a chilling letter in her mailbox threatening to steal what’s most important to her again. And though she wants nothing more than to make him pay for her sister’s life that he stole, she’ll have to watch her back now that there’s a killer on the loose.Warning: This volume contains depictions of suicide, suicide attempts and/or suicidal ideation.
