From K Manga:
Natsumi Eguchi took us to the afterlife with Hozuki’s Coolheadedness. Now, they take us somewhere even stranger: the land of the living. College students Magi and Yaeko’s lives take a strange turn the day a man is struck on the head by a falling dictionary from the sky. Bleeding, dazed, and refusing help from the police or paramedics, he sets off every alarm in their minds. But the real shock comes after. Ever since that chance encounter, the world around them has started to shift. Ghosts. Spirits. Unexplainable things. Whatever this man is, he’s opened their eyes to a realm that was never meant to be seen and a story that was never meant to be told.
