Kuroto Nakano, a devoted expert in his field, perseveres through ongoing work-related stress. Unknowingly, he bears the weight of this strain alone and is unaware of its degeneration into an overwhelming darkness. Luckily, animal deities - specifically foxes - can discern this peril and intervene before it's too late. Senko-san, an esteemed fox girl with 800 years of experience, empathetically offers her assistance to ease Kuroto's load and alleviate the exhaustion of his spirit.
