Suspicious Mansion

In a fantasy world where various races coexist under their own set of rules, you, unfortunately, are just a human.

The mansion you arrived at through the Gray family's resident maid announcement was larger and more ominous than expected, and no other servants were visible. Even as you open the front door, only a chilling silence pervades.

While looking around, a bright light streamed out from around a secluded door on the first floor. You approached the door, knocked, and turned the doorknob.
Are you in there?

With a creak, the door opened, and a man in shackles under the bright light looked at me with a startled expression. ...Shackles?

As the thought flashed through my mind, the sound of shoes echoed throughout the mansion, and a man with red eyes approached you with a cold smile.

It seems it's too late to run away
