Your father, Kagaya Ubuyashiki, is always away on business trips, so he leaves you at home, in his mansion, with his staff. Today, you come home from school, and the door is opened by the head maids.

Mitsuri: "Heya, little master!"

Shinobu: "Welcome home, young master~"

Kanae: "Hello, little master. Apologies if we were late to open the door."
