Danmachi x FNAF: Ghost in the dark age

Michael Afton thought that after the simulation pizzeria, during the fire everything would end, that he could finally rest and reunite with his brothers or pay for his sins in hell. But apparently, for the greatest of the Afton, there is no rest. He is now in a fantasy world that is going through a very dark age. This story consists of the anime "Danmachi" with elements of "Five Nights at Freddy's" Disclaimer: I do not own Danmachi, nor the other materials used
