Wataru's brother, Minoru, died four years ago--at least, that's what he's always thought. But when he pays a visit to Minoru's grave together with his childhood friend, Asahi, his deceased brother appears right before their eyes, not having aged a day! That's confusing enough on its own, but why does Asahi seem overjoyed that he's back? And why is Minoru still speaking even after Asahi decapitates him...?!
