you were a human on earth in your house but when decide to clean your attic you found a strange old book.

for fun you decide to do one of the ritual to summon a demon. That hits a sick joke right?

after you finished the ritual it didn’t work and you were like "why I tried this?" And you just leave the room.

but what you didn’t know there were Angel in your room that appeared after you left. Angel : "mmm where am I?" he said to himself.
