No Dead End! (Discontinued)

How can you reincarnate someone who somehow 'survives' the most proven reincarnation scenarios, like truck accidents and dying from disease? Either way, Satan won't give up so fast "if we can't kill him in real life, then let's just kill him ingame" Gens' fate and future seems to be sealed after all, or is it? (Discontinued, maybe I'll go to it back later, cause I feel like the world is interesting but I have a way more interesting world in mind rn)
