Replacing Rimuru: A Multiverse story

Raj a average guy struggling with poverty and his life dies by the hands of some not important bastard. While bleeding to his death he wishes to be reincarnated as Rimuru and by some luck Voice if the World fulfills his wish. Good thing is that he had been given a second chance with the abilities of one of the most broken characters. Bad thing? He has reincarnated in MHA instead of Tensura while being nerfed slightly. Now, it's only his desire to get strong that will push through all obstacles in this two faced world of Heroes and Villains towards greatness.
