Kurage

A man who overslept on a bus finds himself in a small seaside town. Although he has never been there before, he feels a strange sense of déjà vu. With no bus to take him home, he is forced to stay in town, but an encounter with a mysterious child named Kazuki takes him on a journey. An idyllic yet dangerous fantasy that leads the reader astray into a world of illusion.
