Review Detail of Nah_U_Stupid in Amalgamation of Races

Sometimes OP is good. The MC in this Fic is OP and can already defeat Muzan easily, yet he still gets ordered around by the other weaker demon slayers. Then his wish about being able to turn into a Demon suddenly disappeared all of a sudden. Pathetic excuse for not killing Muzan early. All in all it had a great idea but awful presentation.
