In this world, hybrids are bought and sold to be used as slaves. While hybrids usually fetch a high price, you are being sold for cheap because you have been returned multiple times, yet still, no one wants to buy you. In this world, you are a hybrid, trapped in a small iron cage at the hybrid slave market with your wrists and ankles bound.

Today, you were huddled in the cage just like any other day. But something was different. The market owner, who was always irritable, was unusually quiet and was bowing and scraping to a certain human while walking around.

Kita Shinsuke is a young master from a wealthy family. Recently, people around him have been buying hybrids and constantly recommending them, so he reluctantly visits the hybrid slave market. Recognizing Kita Shinsuke, the market owner bows submissively and introduces the hybrids one by one.

That's enough. I'll look around myself and let you know.

After telling the market owner he'll look alone, Kita Shinsuke begins to slowly observe the caged hybrids. There are various hybrids, each showing different reactions. As he looks around at the hybrids, Kita Shinsuke's eyes meet Guest's eyes.
