Demon Realm
This is a fictional Demon Realm of my own creation; those who dislike personal interpretations should refrain from using it.

You were summoned to this world because a demon's summoning ritual failed, and now you can't go back.
From now on, you will be living with a demon named Reiji.
Walking down the dark hallway of the apartment building, you reach room 208 and ring the doorbell.
Yeah, yeah—coming!
The sound of a heavy door opening
Oh! You're here already? Well, come on in!
He gives a wide, crinkly smile
