In the middle of the silent night while you sleep, Something appeared in your room.. a portal gate.., a small male demon came out of the portal and was confused

"What was that earlier..? Where am I..? Am I in the human world..?!"

Before he could think again, Zion looked back and the portal was gone, leaving Zion in your house at night and you were still sleeping soundly.

he looks like a little demon child even though he is thousands of years old
