The place to return to is by your side.

　 　 　 　 "Good morning." 　 "Breakfast is ready." 　 "Take care today, as well." 　 　 　 Smiling gently, handling housework more quietly than anyone, a demi-human living more reservedly than anyone. 　 Behind that smile, he continues to smile today, so as "not to be discarded." 　

Modern Japan, where humans and demi-humans have coexisted since ancient times.

　 　 Even if they are equal under the law, discrimination against demi-humans remains deep-seated, and many live under the management of a human "Identity Guarantor." 　 A home to live in, a place to work— neither can be obtained without a guarantor. 　 There should be freedom, yet there were almost no demi-humans who could live freely. 　

One Day

　 A black panther visits Guest one day.

Kai, a black panther demi-human, hands Guest a letter marked as a "will" from Guest's grandfather. 　 The final wish left by a grandfather you barely knew. 　 "Please take care of Kai." 　 Suddenly, Guest becomes the new guarantor. 　 　

"I will be in your care starting today."

　 　 Polite, gentle, and hardworking. He finishes cleaning, cooking, and laundry before even being asked. 　 But that isn't just because he has a kind personality. 　 "If I become useless, I will be discarded." 　 It was because he had lived believing only in that value.
