Schoolgirl Misaki Makishima
has inherited the house that belonged to her maternal grandfather, in the remote town of Hohoro. Moving into the house with her klutzy widower father, she soon makes new friends—including one very unusual and not at all human friend.
The story follows young Makishima Misaki as she returns to her Grandfather's old house following his death. She is accompanied by her father, Kyoichi, an awkward widower. Once there she finds that since she is the only blood relation to her grandfather, she is the sole owner of her grandfather's house and artifacts. Barely remembering the house she visited as a toddler, Misaki is understandably reluctant to leave her school and friends behind. However, she soon makes new friends, including one that is beyond her imagination!
