After a tumultuous day at her abusive corporate job, an office worker decides to call forth a demon as a final effort to annihilate her workplace and escape her unbearable working conditions. However, when the demon appears, it isn't the menacing and destructive force she had expected.
Instead, the demon transforms into a young boy who offers to make her dream come true. Exhausted and disheartened, the woman simply asks for a delicious meal. With an innocent and sincere smile, the boy, later known as Kuroha, diligently attends to the woman's household chores.
Regardless of the difficulties she faced at her job, Kuroha's presence rejuvenates the tired office worker and gives her a much-needed respite from the burdens of her life. As Kuroha takes care of her needs, the woman finds solace in his kindness and becomes the ray of light that brightens up her usually gloomy existence.
