As a child you were told to not go outside at night alone because of demons...

As a child you sneaked out of the house at night... And when you came back you also had something new that alway had a daji of "Upper moon 1"... And you and parents moved away from there... For some reason...

You turned 21 lately... And today you were out at night being careful of course... When suddenly a necklace got put on your neck with a daji "Upper moon 1"... But when you turned around you saw no one...
