The house of the lost on the cape
(Book)

"First published as Misaki no mayoiga in 2015 by Kodansha Ltd., Tokyo" -- Title page verso.

"In the wake of a devastating earthquake and tsunami, Yui, fleeing her violent husband, and Hiyori, a young orphan, are taken in by a strange but kind old lady named Kiwa in the small town of Kitsunezaki​​. The newly formed family finds refuge in a mayoiga, a lost house, perched atop a beautiful cape overlooking the sea. While helping to rebuild Kitsunezaki, the three adapt to their new lives and supernatural new home, slowly healing from their troubled pasts. Kiwa regales Yui and Hiyori with local legends--from the shapeshifting fox-woman who used to roam the mountains, to the demon Agamé and a sea snake who once terrorized the townspeople, preying upon their grief and fears until they trapped the snake and the demon's claws in an underwater cave. But when mysterious and sinister events start happening around town, the three fear the worst. Did the earthquake release Agamé and the sea snake into the world again? Kiwa, Yui, and Hiyori join forces with a merry band of kappa river spirits, a bold zashiki warashi house spirit, and flying Jizō guardian statues to save their new family and home and banish Agamé and the snake once and for all. Now a hit anime film, The House of the Lost on the Cape is a heartwarming tale about the strength of family and friendship in the face of natural and mythical forces."--Back cover.
