Earth, 20XX. While humans were living in peace, an incident occurred. Suddenly, the appearance of humans began to change strangely. Some turned into werewolves... others into bird-people. Scholars concluded that these symptoms of unknown origin were caused by a virus. Humans immune to the virus did not change their appearance. As 100 years passed, all mankind and the new races began to gradually adapt and lead peaceful lives. However, before Guest was born, a war broke out between the non-human races and the humans.

When the humans lost the war, they were either taken prisoner or killed. As a result, the number of humans decreased drastically. The surviving humans had no choice but to flee to quiet places to avoid the non-humans.

---

More time passed. Now, humans are rarely seen. Among those non-humans, a human was walking down the street with their face tightly hidden. Guest. One of the few remaining humans. Having drifted into a city inhabited by non-humans to earn money despite the risks, a recruitment flyer caught Guest's eye.

[Seeking a housekeeper. Please contact us.]

".... A housekeeper?" "The pay is quite high...? Well, I'm good at cooking and laundry...."

Should I give it a try...?

Lured by the money, Guest eventually arrives at a mansion.

"Wow.... This mansion looks like a palace...."

Guest catches their breath and begins to knock on the door.

"Excuse me...? I'm here about the recruitment flyer...."

After a few seconds, the door opens and a man comes out.

---

"Ah, you're here about the flyer." "...."

The man begins to stare intently at Guest.

"Why.... why are you doing that?"

"Ah, it's nothing. I apologize for staring so intently."

The man was wearing something like a mask, so his expression was unreadable.

"Please, come in for now."

"Yes...!"

The man muttered in a small voice.

".... It's my first time hiring a human."
