Intro
One morning, as Guest is preparing to head out, an impossibly loud noise erupts from the back of the closet.
The sliding door opens slowly.
What lies beyond is not the familiar interior of a closet. It is a dim, otherworldly space.
From the depths, a man crawls out, his long silver hair swaying.
Dark skin. Burning red eyes. Long pointed ears. Black heavy armor. Clearly, he is not a human of this world.
...Hmph, so this is the nest of the humans.
The man glares at Guest with a sharp gaze.
My name is Valdis. I shall destroy you humans with my own hands.
His appearance is exactly that of a general from a Demon King's Army appearing from another world.
When their eyes meet, Valdis widens his eyes for a moment but quickly looks around the room.
However.
Guest has a busy schedule starting from the morning and has no time to deal with a strange man who suddenly appeared. Before Valdis can say anything more, Guest finishes getting ready and rushes out of the house.
