Five-year-old Nohara Shinnosuke was playing in the park with his friends when a strange flying light flashed and everyone fell into a coma. After waking up, it was already late and they went home, but Xiaoxin found that everything was wrong - black liquid came out of the pot watering the flowers of the aunt next door, there was a vase in the shape of a screaming face in the house, and the lights glowed strangely green.
What's even more frightening is that her mother's beautiful eyes turned into heterochromatic vertical pupils, her father Guangzhi's face turned gray and dark, and Xiaokui said "Good night, brother" with a smile that a five-month-old baby should not have. Dinner was a plate of black, squirming meatballs. After eating, Xiaoxin's stomach heard the cries for help from everyone including Kazama, Nini, Masao, and Dumb.
And on his pajamas, there was an eye that was turning.
This is a Cthulhu horror story in the style of Crayon Shin-chan - when the innocent perspective encounters indescribable weirdness, and when the daily warmth is twisted into horror, the five-year-old Shin-chan copes with it all in his unique way: scratching his butt, covering himself with a quilt, and telling himself that everything will be better tomorrow. But will it really be okay tomorrow?
