Flame Of The Undead

A man with no memories finds himself in a colosseum, one already filled with the bloodshed of the previous fight. While he does not remember anything, he knows one thing. If he dies, he comes back to life shortly after. The fight is over and he is approached by an enigmatic man in full rusted armour. The mysterious man offers to help in the coming battles and assures that they will become the champions of the colosseum.
