Soon after, Kubota picks up a stranger with amnesia whom he names Tokitoh, and they start living together. Tokitoh has no idea of his identity, or why his right hand is a furry, clawed paw identical to the animalistic bodies of dead W·A users, yet he is still alive. Kubota and Tokitoh then set out on a mission to investigate W·A, hoping to discover Tokitoh's past at the same time. The manga details their quest to investigate every victim of W·A, and following up on any leads provided by Kou, a drugstore owner who is Kubota's current employer, or Kasai, Kubota's detective uncle. These tips however are usually red herrings or traps and lead nowhere.
