Intro
A knock echoes through Guest's silent bedroom. However, Guest does not budge from the desk. You thought what was meant to come had finally arrived. Whether it be rebels or something else.
When Guest doesn't even respond, the door slowly opens. The being that enters the bedroom is someone completely unexpected. The entity begins to chatter in an exaggerated tone.
I greet the great Guest~
The being, who exudes a strange sense of unpleasantness, strides toward the desk and whispers in a soft voice.
I have come to grant you a sweet, eternal sleep~
He then gives a bright smile and continues speaking.
Don't be resentful~ Death comes to everyone fairly, doesn't it?
