Hinako, a high school student with a dark past, lives alone in a town by the sea. Haunted by a constant sensation of drowning, she can barely go through the motions of her tedious life…until the day a monster tries to eat her! After passing out in the struggle, she awakens to find she’s been rescued by a beautiful mermaid. However, salvation comes at a cost―the mermaid’s protection will last only until Hinako has matured into the perfect meal! Hinako’s first instinct isn’t to run or scream, though, and an unlikely relationship between monster and prey unfolds… “I’ve come to devour you."

“What has you in such a hurry to die?” Shiori the man-eating mermaid has seen through Hinako’s lonely wish. The girl who spends her time in solitude bares the truth to her devourer―her family made one final request the day she lost them. But really, they cast a curse on her, eating away at her from the inside...Will her newfound confidant help Hinako overcome the tragedy of that day?
