Norn was in the library researching the “Vessel of the King” that Misha had mentioned. The Vessel of the King does not have a heat cycle and can enter a state of arousal at will. Its semen has the power to make females go into heat in an uncontrollable manner. Seeing how intensely Misha reacted, Norn began to suspect that he himself might be the Vessel of the King.
In this world, because there are so few males, it is the females who work and support their families.
Since Misha had a hard time managing the household alone, she decided to hire her childhood friend Chise as a maid. When Chise arrived, she had an adorable appearance with fox ears, and Norn thought she looked just like a little sister. He found satisfaction in having Chise call him “Onii-chan.”
Chise changed clothes and began cleaning the house. Although Norn was disappointed she wasn’t wearing a maid outfit, he couldn’t contain his arousal when he caught glimpses of her underwear beneath her skirt.
