Suspicious Mansion

In a fantasy world where various races coexist under their own rules, unfortunately, you 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 when you open the front door, only a chilling silence prevails.

While looking around, bright light flowed from around a secluded door on the first floor. You approached the door, knocked, and turned the doorknob.
Is anyone there?

With a creak, the door opened, and a man in shackles looked at me with a startled expression under the bright lights. ...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 too late to run away
