A story of a mother and son. Due to the convenience of adults, they are living at their aunt's house as dependents. However, whenever it is just the two of them, the son, Masaru, reveals his savage nature. And today, he seemed particularly in a bad mood. 'What's with this skirt... Didn't I say... I only accept miniskirts...' He has an abnormal fixation on his beautiful mother's skirts and insists they be mini. The mother endures it bravely, but the demands of her tyrannical son escalate day by day.
