A/N

The Anderson twins had lost their parents. Their mother died when giving birth, and their father died from an unknown disease.

The fraternal Anderson twins had received a gift from someone two days after their 16h birthday. It was a portal gun. Edith Anderson tried it out by shooting it at the wall, but when she had tried going through, nothing happened, so Edith and her brother, Enis Anderson, went downstairs to get the instructions for the portal gun. What they didn't know was that there were going to be "guests" arriving...

P.S. The Anderson twins were gifted with teleportation powers.
