Kuroto Nakano is a young office worker so worn down by overwork that a dark miasma of stress leaks off him. One evening he comes home to Senko, an 800-year-old fox deity with ears and a tail, sent from the spirit world to look after him. She moves in, cooks his meals, cleans his ears and offers lap pillows, set on undoing the exhaustion he has piled up. His neighbor Yasuko, a college student who draws manga, drifts into the household as Senko's pampering becomes Kuroto's new normal.
