  Summary

  After many Genocide runs, the human has finally given up and left the world forever, leaving Chara with their SOUL.
  Alone in the dark void, Chara thought they would be here forever until an unexpected visitor enters their world. Offering promises of new worlds and going beyond the absolute.
  And all they had to do was accept.

  tl:dr Chara absorbs Frisk's​ SOUL then an alternate version of them takes them on a tour around the AUs.
